## Abstract

A master application device comprises a plurality of distributed transceivers, a central baseband processor, and a network management engine that manages operation of the master application device and end-user application devices. The master application device communicates data streams to the end-user devices utilizing one or more distributed transceivers selected from the plurality of distributed transceivers. The selected distributed transceivers and the end-user devices are concurrently configured by the network management engine based on corresponding link quality and propagation environment. The network management engine allocates resources to the selected distributed transceivers and the end-user devices during the data communication. The network management engine continuously monitors communication environment information to configure beamforming settings and/or antenna arrangement for the selected distributed transceivers. Beam patterns are selected for the selected distributed transceivers so as to minimize power consumption and/or based on the location and orientation information of the end-user application devices.
