SYSTEM AND METHOD FOR RELAYING SINGLE-HOP TRAFFIC OVER WIRELESS MULTI-HOP NETWORKS

摘要

The present invention relates to a system and method to extend the coverage of a wireless single-hop network (e.g. BLE network) by relaying messages of the wireless single-hop network on a wireless multi-hop network (e.g. ZigBee mesh network), benefitting from a combined single-hop/multi-hop (e.g. BLE/ZigBee) capability of wireless combo devices which can seamlessly bridge between the two wireless networks. As an example, a BLE device sends traffic to a BLE/ZigBee combo radio device that forwards the traffic towards an intended BLE receiver device through the multi-hop ZigBee mesh network. In this way, the single-hop network (e.g. BLE network) can leverage the extended coverage provided by a multi-hop network (e.g. ZigBee mesh network).
