Patent Images
1. A communications system, comprising:
- a first power line communications system (PLCS) subnet;
an upstream communications device in communication with a point-of-presence;
a multi-hop wireless link providing a communications path between said PLCS subnet and said upstream communication device;
wherein said multi-hop wireless link comprises a first and second wireless hop communicatively coupled to each other via a first wireless link;
wherein said first wireless link includes a wireless downstream link in which data travels from said first wireless hop toward said second wireless hop;
wherein said first wireless link includes a wireless upstream link in which data travels from said second wireless hop toward said first wireless hop;
wherein said wireless upstream link and said wireless downstream link are orthogonal to each other; and
wherein said first wireless link comprises a full duplex wireless link.
