See, I thought the Microphone people were lobbying for this result (unlicensed use of the spectrum), but it sounds like they were lobbying against it. This is ironic, considering that (according to other stories related to this one), many microphones are themselves illegally using the spectrum without a license to begin with.
This seems to be similar to trespassing on private land for camping, then complaining when the owner opens the land up for everyone to camp there. The microphone manufacturers were enjoying free and illegal spectrum, and now they don't want to share.
I also agree that it seems pointless to open up new streams of Wireless internet access when so many Telecoms are complaining that they don't have the bandwidth to handle their paying land-based subscribers. But I suppose wireless is easier in that everyone shares the exact same connection, rather than supplying individual bandwidth to individual consumers.
