A performance comparison of three indoor radio network concepts based on time dynamic simulations

Abstract

Today there is growing demand for ubiquitous high-quality indoor wireless communication systems and many different proposals regarding such systems have been brought forward. This study investigates how three different indoor radio network concepts perform in time dynamic simulations when user mobility is introduced. In this new simulation environment a system based on a number of radio-ports connected to a centralized radio network controller is compared to a system based on small pico cells and a system based on distributed antennas. With this particular simulation set up the results indicate that the capacity of the centralized radio network controller is two times the capacity of the pico cellular concept and three times the capacity of the system comprised of distributed antennas. The capacity advantage found here for the centralized radio network controller compared to a distributed antenna solution is smaller than in a previous study. There it was found that the capacity of the centralized radio network controller is four times the capacity of a system with distributed antennas.
