Abstract

The IEEE802.11ac task group has started to establish a next-generation WLAN standard. The wider channel of more than 80 MHz achieving over a 1-Gbps data rate is discussed. We have developed an experimental platform consisting of baseband and RF units in a 2×2 MIMO-OFDM system for the wider channel and evaluated its system performance in a field experiment. A MIMO-OFDM transceiver in the baseband unit is designed to realize real-time MIMO detection and provide a maximum data rate of 600 Mbps. In the field experiment, we evaluated outdoor propagation characteristics at farm and between buildings for outdoor usage in WLAN systems.
