Most of mobile user data service occurs inside building

and capacity and quality of indoor wireless network confront higher requirement

along with construction of high-rise office buildings

business center

and hotel

and so forth. Due to features like high telephone traffic

bad environment of wireless transmission

strong concealment

and difficult engineering implementation of these indoor sites

coverage and improvement of quality become key points of current 4G internet construction. The thesis discovers and studies

with the combination of mobile 4G room construction practice of Inner Mongolia

on room system coverage scheme with variable methods and stronger implementation. It has strong guidance on room construction in the future.
