ZigBee:
ZigBee is a specification based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs). ZigBee operates in the ISM radio bands and its focus is to define a general-purpose, inexpensive, self-organizing, mesh network. The built-in ZigBee chip (just for some items of ViewPAC family) is presented as a ZigBee Coordinator (master). With it, ViewPAC can link up to 255 ZigBee I/O modules. |
