overview:

Centron communication made a survey for Hangzhou city digital TV network coverage, and supply a high quality intensive technical project on the basis of on-spot information and test data, which would covered by depth signal in network coverage important area (government, bus station, university town, super mall).

Case:
Hangzhou Su ning qingchun store was far away from the base station. One to three floors were   serious shields, most of signals were weak, reception field strength normally ranged from -80dBm to-90dBm. Bad signal cant match digital TV requirements. According to the test of wireless environment, technician would design one set 2W wireless frequency repeater as signal source, it could make base station signal to expand and cover with indoor distributor system. This indoor distributor system quantity ensured super mall mobile TV signal requirements, also leaving large margin. With precise calculations and reasonable antenna deployment, this design should ensure a reasonable power distribution and better coverage effect in the future.
