The TELEGRID WZRDnet Wireless Mesh Network is a low power ad-hoc network based on the IEEE 802.15.4 protocol, commercially known as ZigBee®. WZRDnet provides secure voice and data communications without the need for an infrastructure (i.e. no cell towers or satellites required). In WZRDnet each device (i.e., handset or repeater) functions as a router in the network, relaying messages from originator to destination. Unlike other mesh networks, this architecture does not employ base stations or central routing tables thus avoiding single points of failure. WZRDnet is a true end-to-end packet switched network allowing transmission of voice, data and position location information (PLI).
