Clock & Sync

The out-of-synchronization of the base station clock will affect the network quality, which is mainly manifested as the impact on neighboring search and handover of voice and data services and the rise of interference. There are currently three types of synchronization technology in the network.

- GPS repeaters are used to transmit signals to places where they normally cannot reach. 

- Operate by receiving signals with an antenna located outside of a building, and re- transmitting the signals to the indoor area or covered space 

- Provides for consistent and uninterrupted access to signals underground or in other hard-to-reach areas. 

- The use of re-transmitted signals means that the GPS receiver is tracking the current GPS status, so that when the receiver is moved from indoors to outdoors, the receiver is instantly tracking the location, instead of taking several minutes on the acquisition of the current GPS state.
