How it works
The following pictures show what happens ‘behind the scenes’ when a game is played:
After the game has been started, the phone searches for a bluetooth gps receiver to communicate with. This receiver sends the current gps-data to the phone. (see connection #1). The gps-receiver itself calculates the current position by analyzing the signals received from 2 or more gps satellites (see connection #2 + #3).
To exchange the position data between the handsets, they both connect to a gameserver on the internet which forwards the data to the other phone. The connection runs initially over the air (GSM, see #4) to the mobile access provider, then via internet (see #5) to the game-server.
Arrow #6 shows the connection to the phone of the other player, which also works as described above.
