Abstract

Wireless access is known to be power-hungry for mobile devices. A key reason is that devices radiate power in all directions and much of this power will not reach the destination. To address this waste, we present BeamSwitch, a multi-antenna system designed to realize directional communication efficiently. Unlike power-hungry and expensive beamforming, BeamSwitch requires only one transceiver. We provide an 802.11-compliant design and pro-totype of BeamSwitch. Our measurements show that with three passive directional antennas, BeamSwitch reduces the power con-sumption of a commercial 802.11 adapter by up to 20% and pro-vide better quality under diverse propagation environments and extreme rotation.
