Abstract

In this paper, we report on a mobile broadband wireless access (MBWA) system field trial with fast low-latency access with seamless handoff orthogonal frequency division multiplexing (FLASH-OFDM), which was carried out at Sendai city in Japan. Downlink throughput distributions in multiple-cells environment with a sectored cell layout are discussed when the frequency reuse factors are one and three. The field trial results show that the reuse factors of one and three yield the median downlink throughputs of 3.2 Mbit/s and 2.1 Mbit/s, respectively, within 3.84 MHz system bandwidth. It is considered that the MBWA system with the reuse factor of one has higher median throughput by 50% than that with the reuse factor of three in multiple-cells environment.
