Abstract

Various embodiments of electronic communication systems and methods in which an infrastructure in-motion adapts from a first set of communication parameters to a second set of communication parameters while moving from one geographical region to a second geographical region, and associated transmission pattern of the infrastructure in-motion may be modified to either avoid a problem of multiple-region-coverage or to resolve such a problem once it has arisen. The infrastructure in-motion may be a base station or other infrastructure, and any or all of multiple techniques such as beam switching, beam selection, phased array, and null-steering, may be used to modify a transmission pattern. In various alternative embodiments, infrastructure in-motion in one geographical region establishes a first backhaul link with a first core network, moves to a second geographical region, and then establishes a second backhaul ink with a second core network.

Claims

1. A method for adapting a base-station in-motion to a new geographical region, wherein said base-station comprises

an RF power combiner,

a plurality of backhaul antennas, a plurality of radio transceiver chains selectively coupled to said RF power combiner and said plurality of backhaul antennas, and

a path interconnect to couple said plurality of radio transceiver chains to said plurality of backhaul antennas, said path interconnect configurable to connect any of said plurality of radio transceivers chains to any of said plurality of backhaul antennas;

said method comprising;

servicing wirelessly, by said base-station located in a first position in a first region containing a first wireless client device, said base-station transmitting a first transmission radiation pattern encompassing said first wireless client device;

moving, by said base-station, from said first position to a second position, while in said second position said first transmission radiation pattern covering a portion of said first region and a portion of a second region, said second region containing a second wireless client device;

simulating, by said base-station a second transmission radiation pattern and verifying that the second transmission radiation pattern will not adversely affect transmission with said first wireless client device;

adapting, by said base-station, said first transmission radiation pattern to a second transmission radiation pattern, said second transmission radiation pattern covering only said portion of said second region to service said second wireless client device; and

servicing wirelessly, by said base-station located in said second position, said second wireless client device.

2. The method of claim 1 wherein said first transmission radiation pattern is circular in shape.

3. The method of claim 1 wherein said second transmission radiation pattern is elliptical in shape.

4. The method of claim 1, wherein

communications between said base-station and said first wireless client device adhere to a first geographic regulatory restriction and communications between said base-station and said second wireless client device adhere to a second geographic regulatory restriction;

the first geographic regulatory restriction is associated with the first region;

the second geographic regulatory restriction is associated with the second region; and

the first geographic regulatory restriction differs from the second geographic regulatory restriction.

5. The method of claim 1 wherein, while in said first position, said base station is connected to a first core network and while in said second position, said base station is connected to a second core network.

6. The method of claim 1 wherein servicing wirelessly comprises accessing a data base to obtain a set of communication parameters associated with a selected region, said set of communication parameters used to configure said path interconnect to connect a set of radio transceiver chains to a set of backhaul antennas.

7. The method of claim 6 wherein said first region and said second region are associated with different sets of communication parameters.

8. The method of claim 6 wherein said base-station varies said set of communication parameters and updates said set of communication parameters to create an updated set of communications parameters, said updated set of communications parameters utilizing less resources than said set of communication parameters while maintaining a service level, said updated set of communications parameters replacing said set of communication parameters in said data base.
