Abstract :
This paper presents an ASIC hardware architecture of a multi-antenna access point (AP), compliant with 802.11a/b/g standard and designed for outdoor metropolitan-area deployment. The AP has a six-antenna array and its PHY layer implements single-user maximum ratio combining (MRC) and transmit beamforming (BF), as well as downlink multi-user fourfold spatial division multiple-access (SDMA). The clients use standard WiFi 802.11a/b/g networks interface cards (NICs).
