摘要

在距离90 m的气候风洞中,实验评估了水成物对240GHz载波频率下基于mmic的无线数据传输的影响。在43毫米/小时的大雨和3克/立方米的浓雾中,可成功传输高达24 Gbit/s的QPSK调制信号。根据EVM评估气候影响。减小带宽使传输在BER <;1 × 10-3在自由空间光链路失效的条件下。

Experimental validation of adverse weather effects on a 240 GHz multi-gigabit wireless link
The influence of hydrometeors on a MMIC-based wireless data transmission at 240GHz carrier frequency was experimentally evaluated in a climatic wind tunnel over a distance of 90 m. Successful transmissions of up to 24 Gbit/s QPSK modulated signals through heavy rain at 43 mm/h and dense fog at 3 g/m3 is achieved. The climatic impact is evaluated in terms of EVM. Reducing the bandwidth makes a transmission still possible with a BER <; 1 × 10-3 under conditions, where a free space optical link would fail.
