Physical Layer Simulation Study for the Co-existence of WLAN Standards

Interference is a prime factor that limits the performance of devices within the 2.4 GHz ISM Band. Due to the ISM Band being unlicensed and free to all users, there is an abundance of devices within this frequency range. The three most prominent of such devices used for data communication consist of Bluetooth, Wifi, and Zigbee. In order to understand whether these three protocols can co-exist with each other, a physical layer system model will be developed for each protocol. These systems models will be combined and their interaction with each other examined to determine the effects of the interference under different channel conditions. The channel models will consist of general AWGN and Rayleigh fading channels, along with a site-specific case involving both Ricean and Rayleigh fading.
