For many people, a typical wireless network extender is connected by running a certain length of Ethernet cable or wirelessly. Until a few months ago, I was still unknown, and another standard appeared, namely MoCA or "Coaxial Cable Alliance Multimedia".
A few months ago, Actiontec contacted me shortly after they released their latest MoCA network extender WCB6200Q. The solution supports the second edition of the latest binding MoCA standard and is compatible with 802.11ac through its dual-band configuration.
This extender requires your existing router to support MoCA, or alternatively, you can purchase an adapter sent by Actiontec for testing, such as ECB6200. Using a 4x4 radio configuration, the dual-band radio on this solution has a speed of 600Mbps on the 2.4GHz band and a capacity of 1300Mbps on the 5GHz band, and also has dual Gigabit Ethernet ports on the back of the device.
The suggested retail price of the Actiontec WCB6200Q is US$149.99, while the ECB6200 adapter is priced at US$89.99, both with a one-year warranty.
The packaging of Actiontec WCB6200Q is very simple. The light brown box is used for the extender on the left and the ECB6200 adapter on the right.
The scope of delivery of ECB6200 is shown above. It includes a short coaxial cable, power adapter and Ethernet cable.
Looking closely at the adapter, you can find that there are two LEDs on the front edge of the device, while the two coaxial ports on the left are on the right, and the Ethernet is on the right.
Moving on, we have another box of WCB6200Q delivery scope. The situation with Ethernet cables, power adapters and coaxial cables is very similar, but this also includes splitters.
The front of the extender is equipped with six LEDs, from which you can gather information about power, coaxial connections, and wireless activity and Ethernet.
As I mentioned very briefly, the extender does have two Gigabit Ethernet ports on the back of the device, as well as its coaxial input and reset button.
In order to test WCB6200Q, I went to the basement of my house and set up the solution, making it a solution that any ordinary consumer can use the existing coaxial cable. The cable I use is a 50-foot cable, from the basement to my office, it is RG8 coaxial cable. In the basement, I deployed an ECB6200 adapter with Ethernet and coaxial connections, and set up an extender in my office, and connected it to a test PC via LAN. As you can see above, I haven't fully put Actiontec into enhanced mode to reach full performance, and you see the peak at 432 Mbps.
Through a simple LAN test on 2.4GHz, Actiontec was able to generate 95 Mbps.
When moving to 5 GHz, the performance of Actiontec equipment was much better at 245 Mbps.
Since MoCA is a brand new technology to me, I'm pretty sure that somewhere in the test, I might have screwed it up. Having said that, it took me more than a month to solve this problem, and always came up with the same result, which made me think it might need a firmware update. Anyway, I do like this technology and see it very useful for large buildings or multi-storey rental houses. This gives me a build quality that I think is pretty good. At least it’s about the same as every network extender I’ve tested, including all major vendors.
The performance I have seen may be helpful, whether it is for me to figure out how to put the device into enhanced mode, or for Actiontec to issue a firmware update for that purpose. In the test, I was able to reach 432 Mbps over LAN, 95 Mbps on 2.4GHz, and 245 Mbps on 5GHz.
In general, I can only recommend this device to people who do not have access rights or who cannot use CAT5 or CAT6 cables where needed. This device is much better than a powerline network and is a reliable alternative to traditional wireless network extenders.
If you are looking for an alternative to the Ethernet cable to the destination upstairs, then Actiontec WCB6200Q may be a reliable choice.

Any switchboard can add some extra outlets in the room, but it is important to find an outlet that does not make your electronic equipment susceptible to harmful electrical surges. We have spent more than 150 hours researching and testing surge protectors, and we are convinced
Provide the best combination of protection and number of sockets at a reasonable price. It can absorb ordinary household power surges (up to thousands of volts) and then bring it to your electronic equipment to prevent damage and fire. You don't have to doubt whether it is still working, because once the protection fails, it can safely cut off the power, so you know it's time to replace it.
In the test, the surge protector is one of the best protectors to prevent excess voltage from reaching its socket. Once the protection device wears out, it can also safely stop all power sources, and it has 12 AC power sockets as well as coaxial cables and telephone ports.

It has the automatic shutdown function required by our main selection, but the function will only be activated when one of the functions is activated
Failure occurs-if either of the other two parts is used up first, it will protect your expensive electronic equipment part. However, it has prominent LEDs to indicate wiring problems and has as many AC outlets as Tripp Lite's preferred products. In our tests, it works as hard as the Tripp Lite 12-Outlet to suppress surges, and its Joule rating is approximately 30% higher (which means it is designed to last longer, but this is only an estimate). Although it lacks our preferred phone and coaxial ports, it adds two USB ports so you don't have to sacrifice sockets to charge phones, tablets or other small devices. APC's short cable (6 feet) means that it is difficult for you to reach distant outlets, but we think it is long enough for most people.
The Power Air has six AC outlets and two 2.4-amp USB ports, providing a lot of protection in a compact design.
For light power sources (such as under a bedside table or coffee table),
It is a way to protect gadgets (such as phones, tablets or alarm clocks) from surges. It provides two USB ports and six AC power sockets in a circular package, which is smaller than a dinner plate. The USB port provides a total of 2.4 amps of current, which is enough to charge a smartphone or tablet at a high speed, or charge two low-speed devices. The circular socket layout allows it to be used with various plug sizes. Like the APC P12U2, it has a 6-foot cord, which is 2 feet shorter than the cord of the Tripp Lite 12 socket. Although the rated power is low (1,080 joules), the performance of Power Air in its service life is not as good as our main selection and runner-up, but its life may not be as much as that of large models.
Tripp Lite’s Protect It 3-Outlet SK30USB has an automatic shutdown function and provides almost the same surge protection as the full-size model. In addition, it has two 2.1 amp USB ports.

, But provides more protection. It has an automatic shut-off mechanism, making it one of the few three power outlet options we have found, which will disconnect the power when the surge protector wears out. In addition to three AC power outlets, it is also equipped with two USB ports that can provide a total of 2.1 amperes of current. Compared with other small options we have tested, it performs well and can almost block the voltage of larger models. We will choose SK30USB to protect some small household appliances (for example, essential oil diffusers, Nintendo Switch docking stations and coffee grinders) and some smart phones, even when we travel with us.

Our preferred product will provide protection for most devices in most situations. but
Furthermore, it provides the best surge suppression capability of all the models we have tested, enough to reassure owners of high-end electronic products. It turns a 5,000 volt surge into 40 volts, thanks in part to shutting down the circuit, which turns off all power when a surge is detected. Compared with high-end series mode surge eliminators, the PST-8 actually passed fewer voltages in our tests, and the latter may cost hundreds of dollars. But ordinary equipment (such as computer monitors) will be well protected by one of our cheaper paddles, so this model is best for those who insist on providing extra protection for special precious equipment. In addition, it has a sturdy aluminum body and an 8-foot-long cord.

In order to distinguish the facts from the facts about surge protectors, we approached experts in multiple fields when writing the original version of this guide. We talked
He is a veteran with 30 years of experience in the utility industry and a senior vice president of the industry association (American Public Power Association) to learn about grid and utility-scale surge protection. We emailed
He is an insurance professional who has been in the industry since the 1960s and has received advice on the role of homeowners and tenants’ insurance policies in protecting your technology investments.
In addition, since 2016, we have invited Lee Johnson, an electrical engineer with more than 10 years of experience in electronic product design and testing, to conduct four rounds of testing on our preferred products.
Surge protectors provide more than just additional outlets. It is above all a safety device-a relatively cheap method of protecting expensive electronic products. There is no reason for anyone to leave the office, the study or home theater is unprotected, or hang on a worn-out surge protector.
Yes, that's right: surge protectors will not last forever. Most estimates set the average life span of a surge protector at three to five years. Also, if your house has frequent power outages or outages, you may want to

Plug it directly into a wall outlet), it probably never had a worthwhile surge protection function in the first place. No judgment-I once owned the switchboard my parents bought for the first house. But you should replace these substandard options as soon as possible and thank them for not
Every time there is a power surge, the internal surge protection components will wear out more, and there is actually no way to know how much protection is left. Even if the protective measures have long since disappeared, many inexpensive models continue to supply power to their sockets. This is why we recommend looking for a surge protector with an automatic shutdown function, which prevents the device from transmitting power when the protector wears out.
Most estimates set the average life span of a surge protector at three to five years.
Although surge protectors are not very useful in protecting your property from direct lightning strikes, they are
In any case, they can help solve the more common electrical surges that are generated inside a house or building. They can also protect your utility company from sudden shocks and are especially worth a try in areas with unreliable power grids.
If you never want to replace the surge protector, you can look for high-end products.
Or a hybrid surge protector that can be used continuously indefinitely. But their price can easily soar to 10 times the price of our main pick and runner-up, so for most people, they are an impractical choice.
Finally, if you want to protect equipment that may be damaged by a sudden power failure, hard drives that are vulnerable to data corruption, or important equipment that will never shut down (such as
To treat sleep apnea), you shouldn’t use a surge protector at all. Instead, you need uninterruptible power supplies (UPS), most of which have built-in surge protection. (If this describes you, please read our guide
)
We started our research by aggregating the models by scanning the best search results on the websites of retailers such as Amazon, Google Shopping, Walmart and Home Depot, and well-known brands such as Tripp Lite, Accell, and Belkin.
As we did in previous editions of this guide, we considered the different ways people use surge protectors. For our preferred product, we know that we want some heavy-duty products to be used with home theater equipment and game consoles in the living room (or computer equipment in the office). We also studied small devices designed for kitchen sockets or bedside tables, as well as series and hybrid models for people who need the highest surge protection capabilities.
We look for models with several specific characteristics in each subcategory, including the following characteristics:
Screening candidates through these requirements allows us to obtain a short list of nine models to test against our existing picks:
In the next phase of the report, we tested some of the claims made by each company. Any surge protector
Products that have been rated will be stamped on their main body or printed with their surge protection function on their packaging. Although it is easy to exclude the worst models through research alone, we conducted face-to-face comparisons to verify which models provide the best protection.
In the United States, AC power sockets can nominally provide 120 volts of electricity, but because the design of the power brick conforms to the 240 volt standard used internationally, most electronic devices can handle more voltages. In our test, we applied a 5,000 volt surge to each surge protector and measured the current to any connected equipment.
Senior electrical engineer Lee Johnson set up our test parameters. He attaches each model to a
Generate surges along 200 to 5,000 volts and generate surges in 100 volt increments
-Ground (LG), Ground (LN) and Ground (NG)-and record the output results, which will be transmitted to any equipment inserted into the surge protector. Subsequently, he conducted five consecutive 5,000-volt surges and averaged the results. He recorded the output (the lower the better, because this means that the surge protector will block more power in the device) for all three wiring lines. According to the Institute of Electrical and Electronics Engineers, no family will experience a power surge.

In 2016 and 2017, Johnson dissected each surge protector to evaluate its components. He compared the thickness of the wires, the size and layout of the wires

Be incorporated into the design, as well as the overall construction quality. For well-known brands that sell surge protectors (prices between US$15 and US$50), the guts are so similar that no useful information is obtained from the anatomy, so we have not dismantled the models that have been tested since then.
To further illustrate the importance of using a surge protector, Johnson applied a 5,000 volt surge to the (very old) Dell LCD monitor, with or without protection. After the protected hit, the monitor turns on and displays the image without problems. In contrast, when he leaked 5,000 volts directly into the unprotected display, it immediately cried in pain and never turned it on again.
In the latest test in 2020, we did not test any series mode or hybrid surge protectors because we think they are too large for most people. In past tests, we found our early version
In some respects, it showed the same or better results at a lower price. However, when we tested several models before (
), we compare them with the relatively cheap and MOV-based general-purpose products, and put them at the same speed. We applied various surges from 160 volts to 5,000 volts to each surge to observe their response, and then performed another 5 shocks at 5,000 volts to average. We also disassembled each unit and found a similar design and construction, but there are only small differences between the visible components.
We have tested dozens of surge protectors and are confident
It is the best choice for use with typical living room or office equipment. It provides all the safety features you need, ample sockets, excellent surge protection performance, and its manufacturing quality is significantly better than other devices we have tested.
The Tripp Lite 12 socket has an automatic shutdown function. When the device is worn out, it will permanently turn off the power to the device and can no longer prevent power surges. Unlike most surge protectors, which will continue to power electronic devices even after the protection disappears, our choice is safe and trustworthy, because you know that if power is still provided, it still has some protection features. In addition to its automatic shutdown function, the device also has two small LED indicators: one to tell you when the surge protection is working, and the other to let you know if there is a short circuit, a blown fuse, or a wiring problem that requires intervention. From an electrician.
When we send a 5,000 volt surge through the Tripp Lite 12 socket, its suppression capability is the same as any MOV-based surge protector we tested. In our test, its average allowable pass voltage (the remaining amount of surge through the device) was 207 volts. This is much lower than UL's
score.
Please note that the voltage of each surge protector we tested is below 400 volts.
. The discount unit passed a voltage of up to 517 volts on the LN leg, and did not provide any protection on the other two legs. If you care about actual surge protection, please don't buy a general-purpose surge protector.

. You can find surge protectors with more than 12 sockets (for example, Tripp Lite makes a
), but they are usually too large to be used at home, and lack peripheral ports such as USB, telephone, and coaxial connectors.
The Tripp Lite 12 socket also has dual coaxial connectors, so you can connect a cable box and three phone ports. (versus
Connection, phone ports do not support high-speed Internet, so although these ports can be used to protect fixed phones, they cannot be used to protect network equipment from damage. ) If you need a coaxial or telephone connection to set up a media center with equipment, these additional ports are great. Just like AC power outlets, power is also supplied through them, so they may be affected
. For example, power spikes caused by improperly grounded cables (uncommon) can damage unprotected cable boxes. Unlike our runner-up and light aircraft, the Tripp Lite 12 socket does not have any USB ports. But since this type of surge protector is usually placed out of reach (behind a sofa, desk or TV cabinet) and is designed for more heavy-duty purposes, we think that the USB port is not that important.
The appearance of the unit matches the sturdy utilitarian shell, showing its outstanding performance. With ordinary power strips (or even
The surge protector we considered in the last round of testing), its veneer seems to withstand most minor scratches and abrasions. It is compact enough to slide under a bed or entertainment center, and a set of holes on the back gives you the option to mount it on the skirting board. Its 8 feet thick rubber cord is 2 feet longer than 2 feet.
, Which makes it more convenient to run under the bookshelves and sofas. And unlike our other select products, it has
It is an ideal choice for narrow spaces. Tripp Lite provides a limited lifetime warranty to prevent any defects or malfunctions during the life of the product, but please note that the surge protector will not eventually wear out as designed, this is not a defect.
The Joule rating of the Tripp Lite 12 socket is about one-third lower than our Joule rating
: 2,880 vs. 4,320 Joules. The Joule rating tells you how much a surge protector can withstand before it breaks, so our preferred product may not last as long as the APC model. But since this rating is an estimate, and our choice is still higher than many other models we considered, we decided to give more weight to the numbers that can be tested.
Another problem with the Tripp Lite 12 socket is that its space is a bit tight. It has four well-spaced sockets for large power bricks, but the eight sockets in a single row quickly become overcrowded, especially when the plugs are bulky. If some sockets are on the other side of the body, or the device has rotating sockets (such as
. However, the good overall performance of the unit outweighs this subtle defect.
If it is our first choice,
, Not available, please get 12 sockets
. It has as many AC outlets as the AC outlets we chose, the average output and pass voltage recorded in our tests are about the same, and its Joule rating is almost twice that. Like the Tripp Lite 12 socket, it has a lifetime warranty. It is also as sturdy as Tripp Lite, and we hope its socket location is better. However, several major shortcomings (ie poor automatic shutdown function and short power cord) prevent us from becoming the preferred product.
The automatic shutdown function of the P12U2 (to prevent it from being unable to power electronic equipment after losing its protection function) will only appear when the main (LN) branch is worn out. This means that if any of the other two branches (LG or NG) fails first, it will continue to power your equipment, and they may suffer damage in the event of a power surge. There is a silver lining that the P12U2 has two notification LED indicators, embedded in a long transparent plastic strip that extends across its entire body and can clearly indicate when it is no longer able to provide protection, or whether it is present Short circuit or wiring fault. This is the only model we considered in this design. The notification lights of most other surge protectors are the size of a needle.
Like our first choice, P12U2 has 12 AC power sockets. It lacks telephone and coaxial connectors. If you want to connect landline telephones, dial-up Internet access or cable boxes through surge protectors, it may cause inconvenience. However, for everyone else, this is not a big loss. Unlike the Tripp Lite 12 socket, the P12U2 has two USB ports. These are not super useful for media centers, but they are good choices for home offices or any place with devices that can be charged directly via USB.
When we use 5,000 volts to power the P12U2, it prevents surges and our first choice, its penetration voltage is only 205.2 volts-much lower than 330 volts
Rate this surge protector.
Like the Tripp Lite 12 socket, the P12U2 has a limited lifetime warranty to cover all defects. It has a power rating of 4,320 Joules, which is about 50% higher than our preferred power rating (although it can equally protect your equipment from any single shock). As we are explaining
As shown above, a higher Joule rating means that the APC model should last longer, but the rating is only an estimate, and it is impossible to know exactly how long the "longer time" will last.
The P12U2's wire is only 6 feet long, but we think that in most cases, it is still very long. It has four sockets with larger spacing, which can be plugged in larger plugs, such as our first choice, but the other eight sockets are divided into two rows, four in each row, which provides you with more space. Moreover, in terms of build quality, the APC P12U2 is as good as the Tripp Lite 12 socket.

Even if the house looks like a UFO, it is also suitable for light-load use around the house. Like our preferred product, Power Air will shut down safely if it fails to protect your electronic equipment, so you will know when you need to replace it. The low design (approximately 7¼ inches in diameter and 2 inches in height) is perfect for bedside tables or coffee tables with limited space. Despite its small size, Power Air is able to suppress the most common surge in most large models.
Power Air's automatic shutdown function will permanently power off the device at the end of its useful life, and will no longer be able to suppress power surges. This is the safest way to ensure that the surge protector is actually protecting the electronic equipment. Even if you don’t use it to power expensive equipment, you can still use it as one of our main selection products, but it’s good to make you more worry-free.
The number of AC power outlets for this device is half of our top and second place, but we think six are enough for light-duty surge protectors. In addition, it has two USB ports, the total current of these ports is 2.4A, while the old model USB port is 2.1A.
—Therefore, it provides faster charging speeds for most smartphones and tablets. Even if you insert

-The appearance of a well-equipped bedside table-You still have several sockets to choose from.
In our test, when we tested against a surge of 5,000 volts, Power Air could only pass a voltage of 268.8 volts on average. Although their results are close to 200 volts, they are in the same category as our first choice. However, its service life may not be very long. Its rated consumption is only 1,080 joules, which is not lower than the joule ratings of Tripp Lite (2,880) and APC (4,320) models. Even though our other options have a lifetime warranty, the Power Air's five-year warranty is appropriate considering that the life of the surge protector should be maintained approximately, because most protection circuits will wear out within three to five years.
Power Air is sleek and compact, with a flat shape, which can easily slide under the coffee table. Its 6-foot-long cord is thick, flexible and durable, and its outlet leaves enough space around the top of the device so that you can fully access all the wires. Finally, its blue and green LEDs (respectively telling you whether the device is powered on and protective) will be clearly marked and clearly visible on the top.
If you want something that provides strong protection in a small package (for example, powering a few devices and a few smartphones on the kitchen counter), please buy
. In our complete guide
, We recommend that you use models with up to four AC power outlets and up to two USB ports. However, although most of the switchboards only provide low-level protection against power surges, in our tests, SK30USB has almost the same protection capabilities as large competitors.
In addition to the three AC ports on the front, the SK30USB also has two 2.1 amp USB ports. It also has an auto-shutdown function, making it one of the few small portable surge protectors we found with this function.
In our test, the allowable pass voltage of SK30USB (291.8 volts) is at the same level as the allowable voltage we obtained from the best choice and second place (allowed to pass 206.8 and 205.2 volts, respectively), and is much lower than its 330 volt UL score. Although its life expectancy is shorter than our remaining options (rated at 540 joules, while our other options are thousands of joules), it has a lifetime warranty, which is a great deal for such a cheap device. Impressive.
As for the appearance, SK30USB is made of smooth plastic and has a smooth, streamlined design. Even if it protrudes about an inch from the wall when inserted, it blends seamlessly into the background. Like
, There is a clearly visible plastic band on the top of the device, which lights up to show that its protective function is working (on the downside, this light may be annoying in the bedroom when you try to sleep). It has a three-pin plug and a plastic rod that can be inserted into the bottom hole of the second outlet to ensure a tight connection. If you use SK30USB at home, it also has a screw, you can plug it directly into the wall (instead of the screw in the middle of the wall socket board) for a more sturdy installation, but we don’t recommend you to do this if you plan to use this machine To travel. The spacing between the AC and USB ports is very small, but this can be expected on such a small unit.
Most people don’t need this level of protection, but
Provides the strongest surge protection among dozens of models we tested, even better than high-end
It cost hundreds of dollars. Even though our tests have shown that general-purpose equipment such as computer monitors can survive surges when protected by our cheaper options, in some cases, it costs more to increase the level of protection. The money is still worth it. Among the five numbers. If you want complete peace of mind, no matter what situation you encounter, there is no more affordable method than PST-8.
In our tests, the PST-8 repeatedly allowed 40 volts out of a 5,000 volt surge to pass through its eight sockets. Furman no longer relies on the standard MOV to absorb the entire surge, but adds additional protection: After the surge exceeds 137 volts, the entire device will be shut down to protect itself and all connected devices (open and close the device to reset it) . Any surge that passes before the shutdown will pass through a series of capacitors and a large inductor to filter out the excess power. Large-scale MOVs are similar to MOVs in cheaper units, only sacrificing part of themselves as a last resort.
stage. According to Furman, this is why you can't find the Joule rating listed for the PST-8-since other surge protectors only rely on MOVs to absorb energy, this is not an apple-to-apple comparison.
Furman Power Station 8 (PST-8) provides the most powerful surge protection among dozens of models we tested, even surpassing the expensive high-end series-mode surge protectors that cost hundreds of dollars.
The company also claims that since its launch, the circuit design of the PST-8 has resulted in its repair and replacement rate of less than 0.005%. In other words, few customers need to repair or replace their equipment, Furman said, in all cases, the damage is physical damage (dents, cracks, or broken parts), not internal failures. Considering that this setting effectively suppressed our test surge, we have every reason to believe that in the price range of less than $50, PST-8 can provide longer protection time than standard surge protectors.
However, this improved protection measures not only pay a price, but also pay a price. The PST-8 has only eight AC power outlets in total, plus two phone ports and two coaxial connectors. When you try to power a large number of electronic devices, you may feel a headache. Its layout also has some shortcomings. Only two AC power outlets are properly spaced to accommodate a larger plug. Finally, its three-year warranty (
, But only if you start from
) Is one of the shortest models we have seen, which is disappointing because we expect its surge protection function to last longer than cheaper models. (According to Furman's introduction, these devices are often used by touring musicians, so they are more wear and tear than home surge protectors, so the warranty period is relatively short.)
However, if the price of your device is above average, then these trade-offs make sense. Although PST-8 is not very convenient, it will provide better protection than our other pickaxes. Its overall structure is sturdy, with an aluminum body and an 8-foot-long rope.

Sometimes, laying a video cable between the source and the TV (or projector) is not feasible or convenient, especially when they are in a separate room. Although many wireless HDMI solutions can send AV signals in a room, we still like
Because it can reliably transmit signals around the entire house (up to 100 feet), and has more features than other similarly priced systems.
The transmitter can easily and reliably wirelessly send HDMI video signals and 5.1 audio to a receiver up to 100 feet away, and can be powered by a USB port.

It is a low-cost, easy-to-use option that can wirelessly send 1080p and 5.1 HDMI video and audio signals in the entire room or the entire house without degrading the quality. The basic unit has two HDMI inputs and one HDMI output, so you can plug in multiple sources and easily get power from the USB 3.0 port (more information below).

It is a bit more expensive than our main product, but it combines two HDMI inputs and supports 7.1 sound.
If you want to fill the room with other audio,
Support 7.1 sound. Like our preferred product, this model can support two HDMI sources, can be powered through a USB port, and has reliable performance. However, the additional cost prevents it from occupying the top spot.
This does not have our first two options or multiple input ranges, but it is an inexpensive way to transmit an HDMI source wirelessly.

It does not pass through walls as well as other pickups, but it is strong enough to send the signal to the entire room. This is a cheap and easy way to stream HDMI sources. It has only one HDMI input, but it does support 7.1 sound and USB power, and it is the cheapest model we have tested.

The products mentioned here are used to wirelessly transmit high-definition video and audio signals from HDMI signal sources to the TV. There are four main uses for wireless HD products:
But remember, convenience comes at a price. Wireless is always more temperament than wired, it takes some time to synchronize (connect), and it may/occasionally drop.
A few words about all wireless HDTV solutions. Almost every wireless HDTV product can transmit up to 1080p video from any HDMI signal source you send. This includes Blu-ray (2D and 3D), cable/satellite and gaming systems. Most TVs also emit infrared signals, so when you are in another room of the TV, you can control the signal source (such as a cable box) connected to the transmitter. The wireless products covered in this guide can handle all current 720p and 1080p, but they cannot use Ultra HD 4K. However, 4K solutions are beginning to appear (see "
"For more information).
When choosing a product, we searched for the product on Google and Amazon. We also studied the technology used on each product. (Warning: terminology!) There are two main standards for wireless transmission of HDMI signals:
Devices using the same wireless transmission standard will work similarly to each other, and each standard has its own advantages and disadvantages. For example, products that use the WirelessHD standard can transmit uncompressed video. However, they only work when there are no obstacles (such as walls or cabinets) between the transmitter and receiver. In other words, if you want to place the TV in a room different from the signal source, you are out of luck. To make matters worse, many cabinets block high-frequency signals, so hiding the signal source in furniture will not work. In our tests, even walking between the transmitter and receiver seemed to interfere with the signal.
Model using Wi-Fi, for example
, Less common. However, Actiontec is one of the few products that allows you to add other receivers, so multiple TVs in your home can use the same source. For most people, our best option is a better choice, but if there are multiple recipients that are useful to you, then Actiontec is worth a try.
There are other wireless technologies that are not yet widely available on the market. For example, WiGig or wireless gigabit has the bandwidth to handle 1080p video (and then some videos). However, WiGig is similar to WirelessHD and works in the 60 GHz frequency band, so it may have similar limitations.
Intel's WiDi is built into the notebook computer, and does not have the "thousands of miles away" features like the products here. It is worth noting that if your laptop has an HDMI output, although you need to connect to a wireless transmitter via HDMI, you can use one of these products to wirelessly send computer content to the screen.
We connect the receiver part of each product to the TV on the first floor of a small house. Then, we paired four HDMI transmitters with the Blu-ray player and Roku box, located in the four areas of the house. First, place the source device on a table 10 feet directly opposite the TV. Then, we moved the video equipment to a room 20 feet away adjacent to the TV area. This room does not have a door, but it is not within the line of sight of the home theater. Next, move it to an adjacent room, which is separated by a wall 25 feet away. Then, we moved the equipment to the furthest point in the house, in the corner of the bedroom upstairs 45 feet away.
In our final test, all equipment failed: 100 feet from the TV across the street. Many products claim to have this type of range, but unless you have an absolute line of sight between the two products, you can bring a little salt.
We watched several Blu-rays wirelessly, including action, animation, and comedy. Next, we try to stream content from Netflix, Amazon and Crackle. Finally, we played
Use the Roku 3 box, which is longer than we should.
It is the best HDMI transmitter for most people. Using WHDI, it can provide the best image at the longest distance, has two HDMI inputs, and can be powered by the included AC adapter or the TV's USB 3.0 connection (cable not included). It is also the cheapest dual HDMI unit we have tested.
The basic unit of the Iogear transmitter has two HDMI inputs and one HDMI output. This means that you can connect a TV, transmitter, and signal source (such as a Blu-ray, cable/satellite TV box) in one room, while wirelessly sending the same signal to another TV elsewhere in the house.
Throughout the test, the device performed well even if the transmitter and receiver were located on different floors. There is also no significant video delay. This means that gamers who are worried about their twitch skills should not pay too much attention to wireless technology. Due to the encoding/decoding process, it may increase the time by a fraction of a second, but it is less than the time that can be detected using conventional test procedures.
Perhaps our favorite feature of Iogear is that you can use the USB 3.0 port to power the receiver unit (you need to buy your own USB 3.0 rating)
cable). This means that Iogear can get power from the TV without having to connect extra wires to a power outlet. This makes it easy to hide and is an effective alternative to cutting holes in the wall to hide cables. Not every TV has USB 3.0, the receiver may still work with fewer USB connections, but Iogear specifies USB 3.0. If your TV does not have a USB 3.0 port, Iogear will also come with a power adapter. Moreover, the receiver is small enough to fit behind many wall-mounted TVs.
Finally, it should be noted that the GW3DHDKIT transmitter is compact. Unlike our runner-up, GW3DHDKIT has a horizontal design, but it can also be used vertically, so it is easy to slide into the AV cabinet.
in
, Daniel Kumin from Sound & Vision said: "Iogear's solution allowed me to choose the latest solution: the widest range, the most features, and the ergonomics." His only complaint was that it was a bit expensive. But since his review, the price has been cut by almost half, which brings it in line with the WirelessHD product that he doesn't like much.
Mark Anderson from HomeToys
"If you want to place a TV or projector where it is difficult to lay cables, or want to connect a TV in another room to your main home theater, the Iogear Wireless HD 3D Digital Kit may be just a ticket. In all my tests It all worked perfectly."
The genius writer of HD Guru (coincidentally, just like our own Geoff Morrison)
(two over five). In a comparison test with three other wireless HD transmitters
, He said to Iogear: "If Iogear can rush to our preliminary review in time, it will undoubtedly win."
Like all current wireless HDTV solutions, Iogear is not perfect. Although we did not encounter serious problems during the test, a few Amazon reviews reported problems with transmission distance. In our test, our transmitter and receiver are located at the opposite corners of my little house, and good images can be obtained, but compared with a wired connection at the same distance, doing so will result in a significant reduction in image quality. Remember, the result will depend on the size and structure of the house.
In other words, it is unfair to expect any wireless system to work perfectly at the nominal maximum distance, especially in the presence of obstacles. On smaller TVs (such as 50 inches and below), you are unlikely to see a difference in picture quality even at a long distance. In the same room, the image is always perfect.
Please also note that although the Iogear receiver can be powered by USB power, it can only be used with USB 3.0, and there is actually no USB cable (you need to provide it).
Finally, since the transmitter only has two HDMI inputs, if you have more than two HDMI sources (one
Or HDMI switcher would be better).
The price is slightly higher than our first choice
It is another good choice for wireless HDMI use. That extra cost is because the product increases audio support to 7.1. Its performance is very similar to the Iogear model, with two HDMI inputs, one HDMI output and a USB power option (but still not including the cable).
The excellent performance of Aries Home+ is all our test. It uses a technology called GigaXtreme Technology, which operates similarly to WHDI, so it can pass through walls and cabinets. It also has support for uncompressed 7.1 PCM, DTS and Dolby Digital surround sound.
Said: "The overall experience of watching video and TV definitely exceeded my expectations."
This is certainly a good performance, but we doubt whether 7.1 will make most people want to spend extra money. Unless you want to build a complete home theater, for most people, our first choice will be the best choice.
For those who can’t drill, wire or spend a lot of money,
It is a good budget choice. It can stream an HDMI signal source and has the USB power option that we liked very much in the first two choices.
However, this model runs at 60 Hz, which means it is an excellent indoor solution. When sight is available, it works well at medium distances. It does not work properly through walls or cabinets (or does not work at all).
It can support 7.1 sound, including Dolby TrueHD and DTS-HD main audio streams, which makes it unique in this category and price range. If you need a simple short-distance solution, then Blackbird Pro is definitely a good choice.
Companies such as DVDO and IOGear have launched or announced wireless HDMI systems with 4K capabilities, such as
with
. Currently, there is no 4K friendly system that we know of that can transmit HDR wirelessly, only
Support full 4K/60 signal. Since these wireless systems cannot provide a complete UHD/HDR experience, we are unwilling to choose in this category. For indoor settings, we still recommend using an 18 Gbps HDMI cable to get the most stable signal. For remote UHD/HDR settings, you might consider using an HDMI-like fiber optic system
We tested two samples
, Can be sold in houses and apartment environments through Wal-Mart. The Blackweb system can support up to three HDMI signal sources, can pass through walls, and can generate reliable signals in multiple rooms in the house. However, in apartments, the reliability of the signal is much worse. Even if the transmitter and receiver are in the same room, we still see stuttering and blocking in the video. In addition, both Blackweb samples crushed the black, making the image too dark, so you must readjust the brightness control of the TV to compensate. If you are looking for an inexpensive way to wirelessly transmit HDMI around your house, as long as you don't mind changing the TV settings, the Blackweb kit can do the job.
Similar to our budget selection,
Use 60 GHz technology to provide 1080p/60 uncompressed video and audio. This means that it is best used as an indoor solution. Like the Monoprice model, it also has a USB power option and an HDMI input, but the price is slightly higher.
If our popular choice does not have enough investment to meet your needs, then you may want to consider
. The transmitter has four HDMI and an analog component input, which is a convenient choice for people who have multiple signal sources but no receiver, even if it is expensive. However, we think that most people can do it with our preferred product and the HDMI switcher priced at $20.
Egger's
It should be similar to our choice, but farther away. With it, you can stream uncompressed HD content to up to four different displays (with additional receivers). Because it is over $500 and is specifically for a longer range, we believe this is beyond the scope of this article.
Similar to our runner-up, but reduced costs by canceling one of its HDMI connections. It does have support for 7.1 sound, but the price is too high for a single source solution.
It can transmit up to 1080p/60 video through the wall, but its transmission distance is smaller than Aries Home+ (40 feet), only supports Dolby Digital 5.1 audio, and only supports a single HDMI signal source. However, it has the function of HDMI pass-through to nearby TVs. You can also add more receivers, and you can power the transmitter and receiver via USB.
Unparalleled
Similar to Iogear, but with the addition of USB transfer, so you can transfer content from a game controller, keyboard or mouse, but at a higher cost.
