Than existing base station device, remarkable advantage of the present utility model is:
1, helps the covering of the signal of communication of giving full play to and realize the remote cell territory of each base station capacity, thereby reduce operator's investment.
2, the outdoor equipment investment is little, and instant effect is set up 3G network fast for new operator advantage is provided.
Below in conjunction with drawings and Examples the utility model is specifically described.
Description of drawings
Fig. 1 is a normal cellular networking network structure.
Fig. 2 is a networking network structure of the present utility model.
Fig. 3 is the theory diagram of utility model.
Fig. 4 is the networking network structure of case study on implementation.
Among the last figure 1, donor base station 2, reception antenna 3, wireless discharging-directly station 4, reflecting antenna 5, mobile phone 6, transmitting antenna 7, arterial traffic cover 8, remote small towns covers 9, indoor covering system
