以往的集群通信系统是以单区单基站方式实现通信覆盖的,它通过尽可能增加基站天线架设高度,基站发信机采用大功率发射方式,配合移动台的单工大功率发射方式来实现大区制的通信覆盖要求的。但单区的覆盖方式的致命弱点就是无法避免通信盲区的出现,随着移动通信技术的不断发展,蜂 In the past, the trunking communication system was based on a single-cell single base station to achieve communication coverage. By increasing the base station antenna erecting height as much as possible, using the high-power transmitting mode of the base transceiver station and the simplex high-power transmitting mode of the mobile station, System communication coverage requirements. However, the single-area coverage of the fatal weakness is unable to avoid the emergence of communication blind spots, with the continuous development of mobile communications technology, bee
