Coexistence studies for indoor distribution systems of TD-LTE with WLAN system

Abstract

The frequency band 2320-2370MHz is one of the frequency bands for TDD systems in China, the indoor distribution system of TD-LTE will use this band to deploy in the future. On the other hand, WLAN system works in the 2.4 ~ 2.4835 GHz. In this paper, coexistence experiment results between indoor distribution systems of TD-LTE with WLAN AP around the 2.4GHz band were presented first, these results show that the interferences are significant. According to interference analysis, the reasons of interference are found, and the relevant avoiding interference proposals are provided. It will enhance spectrum efficiency and utility and ensures both systems launch harmoniously in this frequency.
