Co-Channel & Adjacent Channel Interference Blocking Performance in 2.4 GHz Band

N. Prabakaran, K.S. Shaji

Abstract


The emergence of several radio technologies such as Bluetooth, and IEEE 802.11 operating in the 2.4 GHz unlicensed ISM frequency band may lead to signal interference and result in significant performance degradation when devices are co-located in the same environment. In the normal mode of operation of co located Bluetooth piconets, nodes in different piconets transmit independently of each other, and thus in band co-channel interference is certain to occur from time to time. IEEE 802.11 and Bluetooth, these two operating in the unlicensed 2.4 GHz frequency band are becoming more and more popular in the mobile computing world. The number of devices equipped with IEEE 802.11 and Bluetooth is growing drastically. Result is the number of co-located devices, say within 10 meters, grown to a limit, so that it may causes interference issues in the 2.4 GHz radio frequency spectrum. In this paper, we investigate the interference issues of 2.4 GHz frequency band.
