SkyMote devices create a 2.4 GHz 802.15.4 based Wireless Sensor Network (WSN).  Our network has control capability also, so Wireless Sense & Control Network (WSCN) might be a better term.

All wireless communication is secured with 128-bit AES encryption.  A password can be used to lock a mote so it will not join unauthorized networks.

A SkyMote network has a tree topology:

Bridge:  A bridge is used to connect the wireless network to a host via Ethernet or USB.  Each network has only 1 bridge.  The wireless tranceiver on a bridge is always on.  A bridge can have up to 16 children (repeaters and motes).

Repeater:  Creates a wireless link between 1 parent and up to 16 children.  The wireless tranceiver on a repeater is always on.

Mote:  End-device with sensors and actuators.  Generally operated in sleeping mode, where the device (including wireless transeiver) is shut down most of the time, and wakes up periodically.  A sleeping mote cannot have children.

The network device limit (bridge + repeaters + motes) is currently set at 128.
