Description
Summary: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. This paper focuses on coverage and downlink throughput performance, which are the most important criteria for assessing wireless data communication systems. The field trial results show that the base-station can communicate to a subscriber at a cell edge with a throughput of 1.5 Mbit/s assuming circular cells of 0.4 km 2 , 0.6 km 2 , and 1.7 km 2 when the sector antenna heights are 19 m, 58 m, and 84 m, respectively. Therefore, it is considered that the MBWA system is suitable to provide a broadband mobile data communication service to subscribers in an urban area.
