High value area depth coverage problem has always been plagued by the operators

the current effective way is to build a set of depth coverage. This scheme

to find the depth of coverage in the area of problems and difficulties in the construction

scheme is proposed to lay a solid foundation. Secondly

it puts forward the depth of indoor coverage ideas

in the traditional coverage scheme based on further improvement of residential indoor depth coverage; secondly

according to the characteristics of the small area of building construct five different depth coverage of each scheme; finally

to optimize the network cell. And the application of the results to the real estate construction

for the latter part of the local area network design optimization provide valuable ideas.
