Develop app so two mobile phones can directly communicate using their network sensor


Mobile phones are like radios which listen/broadcast on their bands. A mobile phone can connect to a base station and then to another mobile phone. Since the mobile phone has a range of 5 km, I would like to create an app that allows two devices to connect to each other without a base station.

Can anyone provide a reference to a book, online tutorial, website.. anything? Thanks in advance!


Solution

  • In current mobile phones, the radio used to communicate with the phone network is not under the direct control of the main CPU, where your application runs. It is controlled by a separate baseband processor, and the software on this is not typically user-updateable (often, it is not even updateable by the manufacturer of the phone!).
