Well it should be possible, but I expect the high-level framework wouldn't support it. You'll have to use a rooted/dev phone I would think.
I'm not an expert on cell networking, but p2p connections are going to be a struggle, because the phone is not designed to work that way. You'll need to handle everything from the handshake to the data reliability, and that's assuming you can put the handsets into some sort of monitor mode so broadcasts can be listened for. You also run the risk of legal trouble if your implementation interferes with the carrier service in your area. If you decided to use the base stations to bounce your transmission, then you have a whole host of issues because by bypassing the carrier you'll have to re-implement key concepts like roaming between stations (unless you hardcode to a single cell in your area) and discovering how the base stations actually work. An interesting idea though, worth doing some research on the radio chip of the handset (or the handsets if you are hoping to support more than one).

My question is: It is possible to implement an application that allows two phone sets to communicate to each other through their radios but without the cellular network? Like a walky talky? But not through IrD, Bluetooth, WiFi. Only using their radios. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Android Discuss" group.
