Abstract

A repeater system includes a first RF repeater device arranged in a first topology of a network of RF repeater devices, to communicate with one or more second RF repeater devices in the network of RF repeater devices to service one or more source nodes and destination nodes in a wireless network. The first RF repeater device deploys an intermediate frequency to frequency shift an incoming waveform. The first RF repeater device detects a change in a network condition in wireless network between one or more source node and the destination nodes. Based on the detected change in network condition, the one or more second RF repeater devices are controlled in network of RF repeater devices to re-configure the first topology of network of RF repeater devices to a second topology.
