Abstract
The present invention provides hybrid access network architecture to provide broadband data, voice and video services over Internet Protocol. The hybrid access network comprises a wireless distribution system which has wireless mesh network nodes acting as wireless repeaters. Each of these wireless repeaters comprises of at least 3 wireless radios. The hybrid access network comprises of plurality of Broadband over Power Line (BPL) nodes, each node consisting of 2 modems and 4 wireless radios. Each of the BPL nodes acts as a repeater. The hybrid access network terminates the wireless traffic with fewer hops and has a very fast low latency BPL backbone of 1-3 milliseconds latency.

15. A hybrid access network, comprising:
-
a cluster comprising a plurality of Hybrid BPL/Wireless nodes (Griffin nodes), each Griffin node comprising at least two BPL modems and at least three wireless radios, where each Griffin node acts as a repeater of BPL signal, and where said plurality of Griffin nodes are connected to a backhaul aggregation point; and a wireless distribution system comprising a plurality of wireless mesh network nodes (Eagle nodes), each Eagle node comprising at least three wireless radios, and each Eagle node acting as a wireless repeater, where said hybrid network is using a combination of said Eagle nodes and said Griffin nodes, and where said network is configured to limit wireless traffic to a maximum of two hops, and, where said hybrid mesh network of Griffin nodes and Eagle nodes provide a system with low latency, high availability, and high throughput for broadband data, voice and video services, and for control applications requiring real time response. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)

31. In a hybrid access network having a plurality of wireless mesh network nodes (Eagle nodes) and Hybrid BPL/Wireless nodes (Griffin nodes), a method of connecting said Eagle nodes and Griffin nodes to provide a system with low latency, high availability, and high throughput, the method comprising the steps of:
-
providing at least two BPL modems and at least four wireless radios in each of said Griffin nodes, at least one of said at least three wireless radios, one wireless radio for providing radio services to user devices and remaining wireless radios for traffic backhaul and redundancy, where each Griffin node acts as a repeater of BPL signal; providing at least three wireless radios in each of said Eagle nodes, at least two of said at least three wireless radios being used for transmission and receiving operations and remaining wireless radios being used for connectivity to user devices, and where each said Eagle node acts as a wireless repeater; providing a wireless distribution system for peer to peer communication among said plurality of Griffin nodes and said plurality of Eagle nodes; selecting different frequencies for different wireless radios of said Griffin nodes and said Eagle nodes, thereby allowing full duplex operation to transmit and receive concurrently at any of said plurality of Griffin nodes or at any of said plurality of Eagle nodes; selecting different frequencies for point to point BPL links to enable full duplex high throughput data transfer over powerline; and limiting wireless traffic to two a maximum of two hops to control latency in the network. - View Dependent Claims (32)
