Everyone has seen the small, inexpensive radio transmitters that allow you to transmit from a portable audio source (minidisc, cd player, etc...) to a car radio by way of an FM signal (usually uses 88.1-88.7, low power stations). My question is this - An 802.11 wireless connection is essentially just a radio transceiver, is it possible to use an 802.11 capable PocketPC to act like one of these inexpensive transmitters, allowing you to broadcast audio wirelessly from PocketPC to car radio?
Another thing, WiFi is sent in a different format than audio. This is a great idea though, and could certainly be done if you have a computer in your car (But only a real geek would have that *nervously whistles*) But it's a great idea for a small device for your car that does this, at 802.11b you could get CD quality (I think) And as the bandwidth in wireless standards goes up, the quality could improve drastically.
It seems to me that the frequency issues are the only real pressing ones - software can certainly be written to encode 802.11 signals into a format that can be received by a car radio... if nothing else, some type of utilization of the transmitter that isn't a two-way connection.
I'm not sure what the frequencies are, but I'm almost positive they aren't anything close to radio, the other thing is can a wireless card transmit the right signal? Perhaps we'll start seeing FM transmiters being built into devices soon?
