随着无线通信技术的飞跃发展,地面移动通信从质和量的方面都取得了可喜的进展。地面移动站成千上万地出现,与此相对应的频率开发也逐渐由150MHz、400MHz频段向800MHz高频段发展,最终达到准微波频带(1～3GHz)的年代将不会很远了。本文介绍地面移动通信的现状,并展望将来的发展前景。
With the rapid development of wireless communication technology, ground mobile communication has achieved encouraging progress both in quality and quantity. Thousands of ground mobile stations appear, and the frequency development corresponding to this gradually develops from the frequency band of 150MHz and 400MHz to the frequency band of 800MHz. It will not be far away to reach the quasi-microwave frequency band (1 ~ 3GHz). This article describes the current status of terrestrial mobile communications and prospects for future growth.
