| Abstract(in English) | For mobile broadband wireless access (MBWA) field trials in urban area of Sendai city, we adopt Fast Low-latency Access with Seamless Hand-off Orthogonal Frequency Division Multiplexing (FLASH-OFDM) system based on Orthogonal Frequency Division Multiple Access (OFDMA). There are 3 cells in the field trial area. Measurement results show that downlink throughput performance is significantly degraded from 2Mbit/s to 1Mbit/s and cumulative distribution of measured signal-to-interference-and-noise ratio (SINR) is impaired about 7dB due to inter-sector interference and inter-cell interference. Since sectorization is mandatory for deployment and operation of the MBWA systems in reuse factor of 1, inter-sector interference reduction is a key issue for systems with same frequency band allocated to all cells and sectors in order to attain high spectral efficiency. |
