| 抄録(英) | Field experiments in the TV White Space (TVWS) were conducted under the White Space pilot program organized by U.K. Ofcom in July 2014, using IEEE 802.11af and TVWS LTE system both of which were developed by NICT, Japan. In the pilot program, it is mandatory for a White Space Device (WSD) to obtain available channels for transmission and maximum permitted transmission power from White Space Database (WSDB) according to its location, antenna height, device class and so on. The WSDB is required to be qualified by the Ofcom after a long test procedure to start the operation. Also, the WSDs are required to satisfy a very hard spectrum mask specified by the Ofcom. NICT has successfully passed the WSDB qualification process and developed WSDs with the spectrum mask requirements satisfied based on IEEE 802.11af and TVWS LTE. Using the developed WSDB and WSDs, the IEEE 802.11af system achieved 2 Mbps downlink throughput over 3.7 km with transmission power of 36dBm EIRP using one TV channel. Meanwhile, the TVWS LTE system achieved downlink throughput of 45.5 Mbps with 20 MHz (contiguous three TV channels) for each of uplink and downlink. It is the first achievement of the TVWS field experiments to measure the throughput of long-distance and broadband wireless link in the center of metropolitan urban area as in London, U.K.. |
