A novel beam combination method for indoor high-speed wireless communication systems

K. Uehara, Kenichi Kagoshima

Abstract

A novel beam combination method for wide-band digital indoor communication systems such as wireless LANs and wireless ATMs is proposed. Crossed fan-beams are used at the base station (BS) and personal stations (PSs). The beam combination method provides better transmission quality than the traditional pencil-beam combination and eliminates complex beam control in the BS. Maximum dispersion distributions in a transmission frequency bandwidth are calculated by a 3D indoor propagation delay simulation algorithm. A prototype fan-beam antenna for the PS is fabricated and measured at 20 GHz.
