从我国开始发展移动通信那天起,直放站就一直活跃在通信舞台上。直放站可以消除移动通信网覆盖盲区或弱区,提高覆盖范围,增强信号覆盖延伸,是基站覆盖的一种有效的补充。然而模拟直放站由于自身限制,在一些特定应用场景难以达到较好的覆盖效果。在这种情况下,将直放站数字化的设计思路运应而生,直放站从“模拟”转向“数字”成为大势所趋。 From the beginning of China’s development of mobile communications, repeaters have been active in the communications arena. Repeater can eliminate mobile communication network coverage of the blind zone or weak area, improve coverage, and enhance signal coverage extension, is an effective supplement to the base station coverage. However, because of the limitation of analog repeaters, it is difficult to achieve good coverage in some specific application scenarios. Under such circumstances, the design idea of ​​digitizing the repeater came into being, and the repeater has become the trend of the times from “Analog ” to “Digital ”.
