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.
