新型内部无线通信网日本邮政省通信综合研究所研制成单位内部无线通信网设施。这种通信网的传送速度与光纤网不相上下。据介绍,这种单位内部无线通信网的主要设施是安装在终端电脑上的小型天线,用电波传送信息,再用安装在天井里的大型天线进行转播,实验用的电波频率为60千兆赫。该设施可以在1秒钟内传送相当于200页报纸的信息量,传送距离为20米,其耗电量相当于无绳电话。新型移动电话英国“技术伙伴”公司与
New internal wireless communications network Japan’s Ministry of Posts and Telecommunications Institute of Communications developed into a unit of internal wireless communications network facilities. This communication network transmission speed comparable with the optical network. According to reports, the main facility of this unit’s internal wireless communication network is a small antenna mounted on a terminal computer, which transmits information by radio waves and is relayed by a large antenna installed in the patio. The experimental radio frequency is 60 GHz. The facility delivers the equivalent of 200 pages of newspaper in less than a second with a transmission distance of 20 meters, which consumes as much power as a cordless phone.
