A Novel Interference Avoidance Technique on Mobile Wireless Routers Using IEEE802.11n PSMP KISHIDA, Akira HIRAGURI, Takefumi OGAWA, Masakatsu NISHIMORI, Kentaro HONMA, Naoki SAKATA, Tetsu Copyright (c) 2010 The Institute of Electronics, Information and Communication Engineers IEEE802.11n IEEE802.16e mutual system interference PSMP wireless relay This paper proposes an interference avoidance technique that allows wireless device with similar frequency bands to be operated adjacent to each other for compact mobile wireless routers (MWRs). This MWR implements two devices of Wireless LAN (WLAN) and Worldwide Interoperability for Microwave Access (WiMAX). The MWR connects WLAN terminals to the backbone network by using WiMAX-WLAN relay. Generally, different frequency channels are assigned for the wireless systems assign in order not to interfere among multiple systems. However, mutual system interference is generated if the space between each device is very close and if the frequency using each system is adjacent. To suppress this interference, this paper proposes a novel interference avoidance technique that leverages IEEE802.11n Power Save Multi-Poll (PSMP). First, we clarify the conditions that raise the issues of mutual interference by experiment. Simulations are conducted to show that the proposed scheme outperforms the conventional schemes. Finally, the effectiveness of the proposed scheme is shown by the computer simulation.
