What Is a Wireless HDMI?
As we all know pretty well, to obtain a high-quality digital video and audio transmission an HDMI cable is needed. But what to do if you need to couple devices installed at a distance and it is inconvenient to use cables? It might happen if, for example, you have more than one floor, or don't want to place wires between rooms on the same floor (which, by the way, might be dangerous). But the solution exists and is pretty simple. The wireless HDMI systems (or wireless video sensors) are easy enough to buy today and there are affordable models available. Well, what is wireless HDMI system? As a rule, it consists of HDMI wireless transmitter and receiver to transfer the image and sound signals from your PC, Blu-Ray player, or Gaming Station to the TV screen, monitor, or projector.
If you still have a lot of HDMI cables all over your room, you might be interested in the HDMI switches and splitters. Also, USB wireless adapters will come in handy if your PC or laptop lacks the built-in Wi-Fi receiver.
What Features to Compare
Data Transmission Technology
The data transmission technology is an important parameter when you are selecting a wireless HDMI device. As of today, WirelessHD, WHDI, and WiFi are used the most often. The differences between these types lie in the operational frequency, the distance the device is able to transfer the signal to, and the ability to pass through the obstacles. WirelessHD is able to transfer video and audio in a really high quality but the transmission range is rather limited, especially if there are obstacles involved. At the same time, both WHDI and WiFi transfer data between rooms through walls and sometimes even ceilings just fine but in some cases, a bit of quality might be lost when the distance is too large or the obstacles are too thick.
Video and Audio Quality
Although for quite some time the manufacturers have been feeding us promises that the technology for 4K video wireless HDMI transfer will be developed soon, today the best video quality we can get from this type of devices is 1080p. But that is a lot! After all, the 4K is still new and unsupported format for many other gadgets, too. Moreover, among wireless HDMI models, you can find those supporting 3D, which is a dream come true for many movie lovers and gamers. And as for the audio, the best quality available is 5.1 or even 7.1 uncompressed surround sound. Look through the specs to see if the model you have chosen supports this quality. Just note that this device is not designed to increase quality but only to transmit the sound as nice as possible so if you are streaming the music from your smartphone, for example, the sound will be based on your smartphone specs.
Operating range is essentially the maximum distance between the transmitter and the receiver that will not result in signal loss or image/sound quality decrease. If you are going to set the transmitter and the receiver far from each other or on different floors, for example, we would recommend you to look for the device with an operation range of 100 ft or more. For using them in the same room, you can get a 30 ft working model.
Interfaces and Compatibility
How does a wireless HDMI work? Usually, all transmitters and receivers in a set have HDMI inputs and outputs, to send and receive signals respectively. The more ports like this the set can boast, the more gadgets and devices you will be able to connect. MiniUSB and USB ports are often provided for maintenance and sometimes you will also find a 3.5mm jack or other port to plug your headphones in. And, of course, there are charging ports. As for wireless HDMI connection, you should follow these simple rules. When you connect wireless HDMI to your PC or mobile device, it is necessary to check the operating system installed on the said device. With other gadgets, however, wireless HDMI is more versatile. If the device has an HDMI port, chances are it will work with wireless HDMI without problems.
J-Tech Digital HDbitT Series
Widened Connectivity Options
The wireless signal transmission at a distance is a necessary option nowadays. When it comes to connecting two multimedia devices, the kit from J-Tech is just what you need. This model supports CEC, EDID, HDCP and, of course, high-quality digital audio transmission. The Advanced Encryption Standard will protect your signal real-time. This wireless HDMI can transmit 4K UHD streaming video, giving many other models a run for their money. Even the newest high-resolution TVs and multimedia players will work perfectly well with the kit. Moreover, the new HDbitT digital transmission standard allows you to transfer data to a surprisingly long distance, up to 660 feet. And no cables anymore!
Even a Child Will Handle It
This wireless HDMI transmitter kit can be controlled from anywhere in the home or office. Both the transmitter and the receiver have IR sensors. For example, if your multimedia player is in another room and you are near the connected TV, you just point the remote towards the IR sensor on a receiver and now you can control this player. This feature significantly simplifies control over your multimedia system, no matter where in the house you are.
We would also like to mention the practicality of both devices. Basically, they look the same. Just the graphic designations on the cases are different. Each of them has an antenna to direct a signal more accurately and improve the transmission quality.
You can even mount them on the wall for greater convenience (there are mounting holes).

All-in-all, this Nyrius ARIES home HDMI digital wireless model will offer you top-notch digital quality of sound.
What Do You Know of HDCP?
Signal protection comes at the top of every manufacturer's priority list, and the High-Bandwidth Digital Content Protection (HDCP) protocol is used by the majority of companies. HDCP is a system designed by Intel to control and manage digital data access via DVI and HDMI interfaces. The main purpose set before HDCP was to prevent the transfer of unencrypted audio and video signals. The HDCP is a licensed product of Intel so the users pay for it but no wireless HDMI systems manufacturers can refuse to use it — a special law enforces the use of this protocol. Plus, HDCP is a mandatory protocol for anyone with the HD Ready certificate.
What Is a Wireless HDMI Extender and Why Do You Need It?
If you wish to enhance your Wi-Fi signal radius, you can opt for a wireless HDMI extender, a device designed for this very purpose.
IOGEAR wireless HDMI review: Forget Quality Losses
When you buy a wireless HDMI system, one of the first things you probably want to know is how far the signal reaches without losing the quality. If this parameter is of utmost importance to you, the IOGEAR Full HD Wireless HDMI kit is a perfect choice: you can place the receiver 100 ft away from the transmitter and the image and sound will be just as clear as it is on the source device, no loss, no distortion, nothing to make the experience less exciting. Mostly, this is due to the WHDI technology used by the manufacturer, is can even penetrate the walls and ceilings. If you have a big house with several rooms and would like to transmit movies and music from your TV to a projector installed on the other end of your apartment, buying this wireless HDMI is your best shot.
AES Encryption History
In case you were wondering, IOGEAR Full HD Wireless 3D Digital Kit uses the AES, Advanced Encryption Standard. So what is it, exactly? AES is a standard that in 2001 replaced the old DES standard. DES had been in use since 1977 and was long outdated. AES was created by a pair of Belgian cryptographers, Joan Daemen and Vincent Rijmen, and was originally named after the two of them — Rijndael. The algorithm turned out to have performance and safety levels so high that in 2001, the U.S. National Institute of Standards and Technology (NIST) approved it as a national standard.
AES is a block encryption algorithm, and each process is performed several times. The block structure is a step up compared to other stream ciphers in that it allows the possibility to change the whole cipher by only replacing a single bit in the key or in the block. There are three Rijndael family members that were selected by the NIST, with three different key lengths: 128, 192 and 256 bits. We'd like to point out that as of today, there are no records existing of hijacking the AES.
IOGEAR Wireless HDMI Troubleshooting
Here are some tips on how to resolve main problems that might occur during use.
- The power indicator LED doesn’t light up. You should check whether the power adapters of the receiver and transmitter are properly inserted into a functioning power outlet.
- No video is displayed on your TV screen. Verify that the wireless HDMI cables have been properly selected and installed between the transmitter input and your device’s output.
- No audio. Please, check if your TV’s volume is properly set or if your source player’s audio volume has been turned up.

Here are some tricks about wireless HDMI:
This type of HDMI is only formally wireless, there are some hidden wires, but they are not visible. "Invisible" wired transmission uses mainly:
- Transmission on the thinnest fiber optic cable, which is flexible and capable of being much longer than the standard HDMI cable, and can also be routed in hard-to-reach places;
- Transmission via electrical outlets using PLC technology. The power grid is available in the majority of inhabited rooms nowadays, so it is very convenient to use it for transmitting an additional signal. It is somewhat similar to the ADSL fast Internet technology (which provided internet using phones). But PLC has some disadvantages too, for example, some vulnerability from "noisy" electrical appliances like old refrigerators.
The innovative 1x2 feature allows you to split HDMI signal to transmit it over 2 receivers. THere is no need for a line-of-sight placement, you can have your home theater devices out of sight without any problems. Furthermore, compared to a single antenna version, this dual antenna modification provides better data transmission rate and more stable video.
