The GUI and firmware have been optimized so that a customer can evaluate a REAL MESH network.
The Voyager kit has been tested for SmartMESH mote hopping. This is where a mote, which is out of range of the network manager, can hop through an in-range mote. The multiple hops network ensures that out of range motes can stream data to the network manager.
Programs like TeraTerm or PuTTy can be used to interface diretly with the SmartMesh manager where you can access networking statistics and performance metrics.
