hroughput goes below 1.0 Mbps for the same SNR value. The data throughputs via QPSK and 8-PSK remain roughly at 2.0 Mbps and between 2-3 Mbps respectively for 0-250 km/h speeds. Vehicular-B which is for medium delay spreads, provides a slightly worse outcome, in contrast to Vehicular-A model. 6.8.2 Field Trial The technology field trial was carried out in a typical urban area, Sendai city in Japan [9]. Three cells were used, each having three sectors and the number of subscribers per sector was one. The focus was on the downlink throughput performances in multiple-cell environment with a sectored cell layout with the frequency reuse factors of one and three [9]. Next Generation Mobile Communications Ecosystem The same frequency band was allocated to all cells and sectors and the system bandwidth was 1.28 MHz with frequency reuse factor of one. Different frequency bands were allocated to the neighboring sectors, and the same frequency allocation is used in all cells with frequency reuse factor of three. The system bandwidth was 3.84 MHz with frequency reuse factor of three. The key results are as follows: The reuse factors of one and three yield the median (at 50% outage probability) downlink throughputs of 3.2 and 2.1 Mbps, respectively, within 3.84 MHz system bandwidth. The downlink throughput was higher than 1 Mbps in almost all the field trial areas (excluding cell and sector edges). The inter-sector interference and inter-cell interference lowered the downlink throughput at sector edges and cell edges. The frequency reuse factor of three yielded a higher SNIR (signal to noise and interference ratio) than the reuse factor of one because of wider system bandwidth. 6.9 Industry Outlook MBWA (Wideband mode) has been put on the back burner by the industry and there are hardly any commercial deployments or rollout plans from any operator. Some industry news for 625k-MC mode (also known as iBurst) is as follows: Kyocera Corporation is the leading manufacturer of iBurst devices announced a USB-type modem for iBurst (
