In order to improve the throughput and delay performance of indoor wireless transmission, a method of using indoor wireless coverage based on dynamic statistical multiplexing (DSM) is proposed. The method is based on the parallel computation of pipeline and is characterized by dynamic statistical multiplexing Architecture.Through the comparison of several popular access technologies in the world, this paper analyzes the performance characteristics of the technology and several classical wireless access methods, and points out the limitations of the classical access technologies in the face of the demand of wireless broadband transmission. From the theoretical analysis, the dynamic statistical multiplexing can approach the limit value of the throughput and the delay, and through the simulation experiment, gives the throughput and delay curves, and compares the effectiveness of the statistical analysis.The simulation results show that: The main effectiveness index plays an important role in providing new methods and ways to improve indoor wireless transmission and coverage performance.
