New wifi telemetry data link _anyone tried it?

I noticed on ebay that a new telemetry data link is being sold. It is a wifi based mav link It claims to have a range of between300 and 800 meters.
Does anyone know what the range is of the 3dr radio 915. I’m guessing approximately 1000 meters. It will certainly be interesting to see what people think about it.

Have you tried it? It looks like it is only an air module. i wonder if boosting of your laptops wifi antenna would be necessary.
