Abstract

A digital overlay covering method includes a down link trunking and an up link trunking, wherein the down link trunking includes: receiving the signals, processing the signals, packing the framing digital signals, transmitting to a plurality of covering units through the optical fiber or five line transmissions, decoding the frame, completing the signal coverage transmitted by the antenna; the up link trunking comprises: receiving the signal, processing the signal, packing the framing digital signal, transmitting to the access unit through the optical fiber or five line transmissions, decoding the frame, transmitting to the base station system through the antenna of the access unit or the potical fiber / five line transmissions. The invention also provides a digital covering system. The method and the system of the invention adopt the digital signal processing, the digital signal transmission, the digital distribution, reduce the loss and the noise of the signal. An access unit is added at the entrance of the building, transmitted to the inside of the building through the wiring, and the coverage unit is accessed at the required position, namely reaching the requirement to be compatible of the multi-system and multi-frequency range, to complete the coverage of the signal.

Description

【Technical field】 [0001] The invention relates to indoor coverage technology in the communication field, in particular to a method and system for indoor coverage in a digital manner. 【Background technique】 [0002] In modern cities, buildings are getting taller, more and more dense, and most of these buildings use reinforced concrete structures as the skeleton, coupled with fully enclosed interior and exterior decoration, which seriously shields and attenuates wireless communication. Wireless signal; In addition, in the ground floor of high-rise buildings, such as underground parking lots, underground shopping malls and other places, the wireless signal is usually very weak or even no wireless signal. [0003] In order to solve the above problem of indoor coverage of wireless signals, the current method usually used is to build an indoor distribution system, which directly introduces the signal of the base station to each area of ​​the room through a wired method, and then t...
