TeamTrak Over BlueTooth. Although Bluetooth has a much shorter range than Ethernet, it consumes much less power and could be used to carry information from, say, a high powered node mounted on a vehicle to nearby inexpensive handsets. Modify TeamTrak to also pass packets over Bluetooth, in addition to Ethernet. (Hint: Make use of the Windows sockets interface with the AF_BLUETOOTH address family, so the code will be similar to that of the ethernet.)
