DVDO Air - Transmission Tests



Obviously a potentially critical element of the DVDO Air system is its effective range. DVDO claims that the system should work over distances in excess of 10m without a direct line of sight, or as far as 30m with a direct line of sight. You also shouldn’t have to worry about any interference from other Wi-Fi gear in your house as the system offers six different channels within its 60GHz operating band.

Pretty easy to use
Many people still identify setting up Wi-Fi systems with brain-bending complications. But in principal, at least, the DVDO Air system really couldn’t be any easier to use. Connect up your source to the transmitter and your screen to the receiver, and that’s it. As soon as you power the two units up they automatically find each other and start transmitting their signals.
We did suffer on a few occasions during our tests with the DVDO transmitter not handshaking properly with our Panasonic Blu-ray player. But this was always easily fixed by powering down the Blu-ray player and then firing it up again.

Both the receiver and transmitter feature single HDMI inputs, scan buttons you can use if you want to switch between multiple receivers, a simple on/off power switch, a power light indicator, plus on the receiver there’s a ‘link light’ – a light that shows you the status of your connection with the transmitter.

Robust signals
To test the robustness of the DVDO Air transmission system, we placed the transmitter and receiver around 7m apart and tried sticking a variety of things – boxes, TVs and even ourselves (humans being the most likely things to suddenly get int he way as they wander around the house) – at varying distances in front of both the transmitter and receiver units. And remarkably the signal remained totally robust at all times, even with objects placed so close to the receiver/transmitter that they were practically touching it.
We even tried wrapping a shirt around the edges of the transmitter at one point, and still the signal suffered not even a flicker of lost synchronisation or content degradation.

This is a genuinely excellent result that says much about the level of electronics that have been squeezed into the transmitter and the slightly smaller receiver.

Both units are built in a cylindrical format (with TV top and wall mount brackets for the receiver helpfully included in the box) which presumably allows them to beam and receive their signals in and from pretty much all directions. That they can do this without suffering any apparent crosstalk between all the signal beams is very laudable indeed, especially when you consider how much data is contained within the streams.
