基站站址选择 ¾General Principles 9 as close as possible to the planning site，make for the network optimization later; distance between sites in dense urban area： 200～300m，deviation should be less than 50 m ； distance between sites in urban area： 400～500m， deviation should be less than 100 m ; distance between sites in suburban or rural area： 800～1000m， deviation should be less than 200 m . 9 site position choice for early establishment should meet the coverage in hot area, such as highway、market or temple ; 9site position choice in dense urban buildings should avoid the tall buildings or the construction of tall buildings near the antenna ；
基站站址选择 ¾General Principles 9 Try to avoid large electromagnetic interference, the choice to the electromagnetic environment around the site should avoid radar stations, power stations or high voltage lines (> 30 m); 9 Leasehold BTS room is the primary choice，building the roof top tower，reducing investment ，attention to the building load-bearing; 9With transmission conditions.
