由于高频和宽频带的特性, W波段毫米波可支持高速率、远距离无线传输, 在未来无线通信中是一项很有前景的技术。为研究 W波段毫米波的无线传输特性, 建立了 W波段无线信道模型, 进行链路分析, 并基于光生毫米波技术进行了实验研究。结果显示, 可以成功搭建 1.485 Gb/s, 90 GHz的W波段实时通信系统, 并成功实现了高清无压缩视频无线传输 265 m。迄今为止, 这是高清视频信号在 W波段实时无线传输的最远距离。

W-band millimeter wave can support high speed wireless, long distance transmission due to the characteristics of high frequency and wide bandwidth. It is a very promising technique in future wireless communication. To investigate the wireless transmission characteristics of W-band millimeter wave, the model of W-band wireless channel is analyzed, and millimeter wave based on photonic beating technique is generated through experiment in this paper. The results show that the 90 GHz W-band real-time communication system with bit rate of 1.485 Gb/s is set up, and uncompressed High-Definition video(HD video) data is successfully transmitted over 265 m. This is the longest distance using W-band millimeter wave to deliver a live uncompressed HD-video wireless signal so far.
