The Wireless HDMI Round Up Testing

I tested the solutions in a few different situations: With the transmitter next to the receiver, across the room and unblocked, in an adjacent room, and then across the house with multiple walls between them. I though this would give a good sample of how people would intend to use the devices in a real-world situation. My home also has both 2.4 GHz and 5 GHz wireless networks that are active, using the widest channel bands available, so even if you have something in the 5 GHz range in your home you could expect similar performance I believe. All of these are also plug-and-play setups, so once they were connected I needed to do nothing to make them work. I used an Oppo BDP-93 for some of the testing, and the video output of my MacBook Air for some additional testing as well.

With the receivers under 5' from their transmitters, I had no issues as expected. If they had failed this test, I probably would have scraped the testing as a whole. Moving the transmitters 20' across the room with open air, I had no issues still. The signal was good and strong, and both real world content and test patterns showed no loss of resolution or color data. For many people this would correspond to their use of these in real life, letting you send content to a screen across the room, or to a projector mounted away from your components.

The next test was the same distance as the 20' open-air test, but had no direct line-of-sight of the transmitter. In this case I expected the DVDO to have issues, but it easily bounced off a wall and continued to work just fine. Once I closed a door between the transmitter and receiver, the DVDO stopped working as expected. The other solutions continued to work well, with very few issues coming up at all, and often performing flawlessly despite the wall now in their way.

The hardest test was trying to go across the house with multiple walls and a staircase in the middle. I couldn't get the DVDO to bounce through the doorway and off multiple walls to work here at all, so it is not good for this situation. The IOGear began to fail a little more often here then I found usable and isn't something I would use for this either. The Belkin had the best performance of the three. It usually kept a strong signal and good picture here, even with all of the walls in the way. It still suffered from some breakups and audio issues, but it was watchable if necessary, which was more than the other two could manage. I don't think any of them would be good for this for daily use, but for sometimes streaming content to a remote room in the house it might be acceptable.
