日本ITR光电波通信研究所灵活地运用了光纤和毫米波无线的大容量性制成一种新传送系统,并成功地对其进行了基础实验。为了使移动通信多媒体化,必须能高速地传送数据和活动图象。但目前所采用的无线频带带域比较窄,不能进行大容量传送。因此,该研究所把电波资源开发的目光放到了毫米波带,提出 Japan ITR Institute of optoelectronic wave communications flexible use of optical fiber and millimeter wave wireless bulk to create a new transmission system, and successfully conducted its basic experiments. In order to multi-media mobile communications, must be able to send data and moving images at high speed. However, the band of the wireless frequency band currently used is relatively narrow and can not be transmitted in large capacity. Therefore, the Institute put the focus on the development of radio resources into the millimeter-wave band proposed
