High back flow of LTE indoor cell directly affects the perception of indoor 4 G users

while greatly reducing the LTE network resident rate indicator. Due to the closed indoor wireless environment

and the coverage of independence of the indoor cell

the effect is not obvious just by the adjustment of parameters. This paper which is aiming at the influence of the high back flow problem of indoor user perception

is started from the standard of high back flow

to expound the causes and solutions

propose the solution to the various types of the high back

and finally provide the reader with effective scheme of discovery

analysis and solution to the high back flow

so as to provide guidance to the research methods to solve the problem in the high back flow LTE indoor cell
