Tools and software for Site surveyTools and software for Site survey

GPSGPS：：

The main purpose：Save the site ；navigation；Measure the distance between two sites。

The precision of the GPS must be more than5~8meters ,when we note the longitude and the latitude,so we must wait a while after open the GPS.

基站站址选择基站站址选择

as close as possible to the planning site，make for the network optimization later;distance between sites in dense urban area： 200～300m，deviationshould 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 .

site position choice for early establishment should meet the coverage in hot area, such as highway、market or temple ;

site position choice in dense urban buildings should avoid the tall buildings or the construction of tall buildings near the antenna ；

General PrinciplesGeneral Principles

基站站址选择基站站址选择

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);

Leasehold BTS room is the primary choice，building the roof top tower，reducing investment ，attention to the building load-bearing;

With transmission conditions.
