Interference Effects of Blue tooth on WLAN Performance
In this paper, Network stumbler version 0.4.0 was used to estimate the impact of impulsive interference on Wireless Local Area Network (WLAN) when Bluetooth coexist by measuring radiation from a WiFi Access Point (AP) in a homogeneous and heterogeneous scenarios. The parameters measured include Received Signal Strength (RSS) and Signal-to-Noise ratio (SNR) while Bit Error Rate (BER) performance was theoretically deduced from the measured data. Results obtained from the measurements of both scenarios were compared and used in describing the interference problem. The study revealed that Bluetooth impact on performance was minimally significant with mean degradation of 4.74% in RSS and 0.77% in SNR despite the fact that its signal are weak and are designed to accommodate WiFi devices by AFH technology.
