New Sharp AQUOS Cordless LCD TVs

i4u writes "I4U reports about Sharp introducing AQUOS a new line of cordless LCD TV Sets. Sony introduced beginning of April the cordless Sony Vega TV series. Now Sharp introduces their line of cordless TV Sets. The Sharp AQUOS LC-15L1 is a 15" LCD TV set that has no wires. The display is powered by a built-in lithium battery. The AV signal is transmitted wirelessly from the base station that contains the tuner. The AV signal is transmitted over 2.4Ghz. The cordless Sony Vega TV series use 5GHz to avoid interference, so Sharp is a bit behind here. The AQUOS LC-15L1 will retail for about 175,000 yen starting May 1st in Japan." These look pretty cool, but of course the battery life and/or battery pricing could be an issue. I guess it depends on how important it is to be able to carry your TV from room to room.

Yes, it is because it is - along with 5 Ghz and a couple of more frequencies - unregulated (or minimally regulated for commercial and scientific use. 5 Ghz, according to this excellent article on Dan's Data is "inherently even less able to deal with propagation obstacles than 2.4GHz".

Just to add to what I said, since in the end it sounded as if I was implying that 2.4 GHz is always superior to 5 GHZ:

2.4 GHz transmission does, indeed, propagate better than 5 GHz, if it wasn't for the considerable existing sources of 2.4 GHz radiation - lots and lots of stuff uses 2.4, as the original poster pointed out, including microwave ovens. So if you're in a interference rich environment, 5 GHz might work better than 2.4 GHz. This is all covered in the article I linked to, incidently.
