Abstract
A Dynamic Frequency Hopping Community (DFH Community) is formed from a plurality of Wireless Regional Area Network (WRAN) cells wherein each of the plurality of WRAN cells within the DFH Community is a one-hop neighbor of the leader cell. The leader cell sets and distributes a hopping pattern for use among the WRAN cells based on, in part, the number of usable channels and whether a WRAN cell is shared by two groups in the DFH Community.
Claims21
A system for dynamic frequency hopping (“DFH”) among a plurality of wireless regional area network (“WRAN”) cells wherein each WRAN cell includes a base station (“BS”) and a plurality of consumer premise equipments (“CPEs”) associated with the BS, the system comprising:
- a DFH Community formed from the plurality of WRAN cells wherein at least one of the plurality of WRAN cells in the DFH Community is a leader cell and wherein each other of the plurality of WRAN cells within the DFH Community is a one-hop neighbor of the leader cell;
- a number of channels for communicating between each of the CPEs and BS of the plurality of WRAN cells;
- and
- a hopping pattern set by the leader cell wherein the hopping pattern hops over the number of channels providing interruption free working channels and mutual interference-free sensing among each of the plurality of WRAN cells in the DFH Community.
A method for dynamic frequency hopping (“DFH”) among a plurality of wireless regional area network (“WRAN”) cells wherein each WRAN cell includes a base station (“BS”) and a plurality of consumer premise equipments (“CPEs”) associated with the BS, the method comprising:
- forming a DFH Community from the plurality of WRAN cells wherein at least one of the plurality of WRAN cells in the DFH Community is a leader cell and wherein each other of the plurality of WRAN cells within the DFH Community is a one-hop neighbor of the leader cell;
- determining a number of channels for communicating between each of the CPEs and BS of the plurality of WRAN cells within the DFH Community;
- and
- by the leader cell, setting a channel hopping pattern wherein the channel hopping pattern hops over the number of channels providing interruption free working channels and mutual interference-free sensing among each of the plurality of WRAN cells in the DFH Community.
A base station (“BS”) in communication with a plurality of consumer premise equipments (“CPEs”) using dynamic frequency hopping (“DFH”) forming a wireless regional area network (“WRAN”) cell, said BS comprising:
- a machine capable of executing instructions embodied as software;
- and
- a plurality of software portions, wherein one of said software portions is configured to transmit a request to a DFH Community wherein the DFH Community includes a plurality of WRAN cells separate from the WRAN cell and wherein at least one of the plurality of WRAN cells in the DFH Community is a leader cell and wherein each other of the plurality of WRAN cells within the DFH Community is a one-hop neighbor of the leader cell;
- one of said software portions is configured to respond to a request from the leader cell for a list of channels associated with the BS with said list of channels;
- and
- responsive to receiving acceptance of the request, one of said software portions is configured to execute a channel hopping pattern set by the leader cell.
