RESUMO

This MSc thesis deals with the interference between the IEEE 802.11g and Bluetooth wireless network systems. More specifically, it was analyzed the impact that Bluetooth transmissions causes on IEEE 802.11g data transmissions. Five parameters were analyzed: transmission time, average packet transmission rate, average data transmission rate, number of lost packets and number of duplicate ACK packets. By comparing the results obtained for these parameters with and without Bluetooth interference, it was possible to determine that the Bluetooth transmission affected the IEEE 802.11g one. The experiments were performed at three distances between the Bluetooth and Wi-Fi transmitters and receivers. Initially, the interference was measured for the distance of 1.60 m. Then, for 2.60 m and, finally, for 4.60 m. For the distances of 1.60 m and 2.60 m, there was no obstacle between the transmitter and receiver devices. For the distance of 4.60 m, there was a wall of bricks covered with plaster. The results obtained showed that the Bluetooth interference on the IEEE 802.11g transmission increased with the distance, being more significant for the distance of 4.60 m
