| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Quasi millimeter-wave and millimeter-wave model network was developed in Ookayama campus, Tokyo Institute of Technology. The objective of the model network is to investigate propagation characteristics for outdoor applications, such as fixed wireless access (FWA) systems, heterogeneous network connecting between the millimeter-wave FWA network and cell-phone wireless networks, and so on. The model network consists of 10 FWA lines, with 7 FWA base stations, and 3 cell-phone base stations. This paper reports propagation characteristic measurement of 25GHz FWA system using the model network. Rain rate, receiving level, bit error rate (BER) are recorded every 5 seconds via the model network. By processing the measured data, rain attenuation, attenuation by raindrops on radome, difference of rain attenuation by V-pol. and H-pol. etc. are extracted. Cumulative rain-rate distribution is also calculated. | |
