Abstract
An intelligent backhaul system is disclosed for deployment in the presence of existing radio systems. A backhaul system for co-channel deployment with existing licensed and unlicensed wireless networks, including conventional cellular backhaul radios, Common Carrier Fixed Point-to-Point Microwave Service, Private Operational Fixed Point-to-Point Microwave Service and other FCC 47 C.F.R. §101 licensed microwave networks is disclosed. Processing and network elements to manage and control the deployment and management of backhaul of radios that connect remote edge access networks to core networks in a geographic zone which co-exist with such existing systems or other sources of interference within a radio environment are also disclosed.
Claims34
An intelligent backhaul radio comprising:
- a plurality of receive RF chains;
- one or more transmit RF chains;
- an antenna array comprising a plurality of directive gain antenna elements, wherein each directive gain antenna element is couplable to at least one receive RF or transmit RF chain;
- and
- an interface bridge configured to couple the intelligent backhaul radio to a data network, the interface bridge comprising one or more Ethernet interfaces to couple the interface bridge to the data network
- wherein the intelligent backhaul radio is configured to scan a plurality of radio frequency channels for the presence of radio signals transmitted from one or more unrelated point to point microwave systems to generate scan data, and wherein the intelligent backhaul radio comprises at least one adjustable network parameter that is adjustable based on the scan data
- wherein the at least one network parameter is adjusted to reduce a potential of interference of the intelligent backhaul radio with the one or more unrelated point to point microwave systems
- wherein the intelligent backhaul radio is a first intelligent backhaul radio, and wherein the adjusting the at least one network parameter comprises one or more of:
- selecting a frequency channel utilized between the first intelligent backhaul radio and a second intelligent backhaul radio;
- adjusting the effective radiation pattern of the first intelligent backhaul radio;
- selecting one or more of the plurality of directive gain antenna elements;
- and
- adjusting the physical configuration or arrangement of the one or more of the plurality of directive gain antenna elements.

- and
- a server in communication with the intelligent backhaul radio, wherein the server is configured to receive the scan data from the intelligent backhaul radio,
- wherein the at least one network parameter is adjusted to reduce the potential of interference of the intelligent backhaul radio with the one or more unrelated point to point microwave systems,
- wherein the intelligent backhaul radio is a first intelligent backhaul radio, and wherein the adjusting the at least one network parameter comprises one or more of:
- selecting a frequency channel utilized between the first intelligent backhaul radio and a second intelligent backhaul radio;
- adjusting the effective radiation pattern of the first intelligent backhaul radio;
- selecting one or more of the plurality of directive gain antenna elements;
- and
- adjusting the physical configuration or arrangement of the one or more of the plurality of directive gain antenna elements.
