随着通信技术的迅速发展,各种通信新技术不断应用于短波通信领域,使短波通信质量得以很大提高。加之短波通信具有机动、灵活、安全、经济、抗灾害能力强,使用和维护方便等优点,所以至今短波通信在国内外仍有广泛的应用前景。本文针对我省通信状况,提出了建立我省短波随时可呼叫系统的基本设想,最后结合一个简单、经济实用的“随呼系统”作进一步介绍。 With the rapid development of communication technology, various new communication technologies are constantly applied in the field of short-wave communication, which greatly improves the quality of short-wave communication. In addition, the shortwave communication has the advantages of maneuverability, flexibility, safety, economy, disaster resistance, convenience of use and maintenance, etc. So far, shortwave communication still has a wide range of application prospects at home and abroad. In this paper, according to the situation of our province’s communication, this paper puts forward the basic idea of ​​establishing a short-wave system in our province, which can be called at any time. Finally, it introduces a simple, economical and practical “calling system”.
