ANALISA INTERFERENSI ELEKTROMAGNETIK PADA PROPAGASI WI-FI INDOOR

Information and communication technologies evolve rapidly. One is with Wi-Fi technology, particularly Internet technology developments that are accessed Wireless (Wireless network). Designed for IEEE 802.11b to cover large area, up to a diameter of 100 meters, and connect 100 of computers that operate on four data rate Different ie 1, 2; 5.5; and 11 Mbps. This condition is risky interference when Wi-Fi technology and Bluetooth are used concurrently. This is because both technologies are equally operate in 2.4 GHz frequency band. At the end of this project has been carried out measurements to see the influence of interference Bluetooth against several parameters Wi-Fi IEEE 802.11b which is indicated by throughput based on the changes data rate. Based on the throughput can be obtained value delay and jitter. The results obtained were the presence of Bluetooth Wi-fi influence is expressed by throughput which influence the throughput is the throughput value decreases with increasing distance between the transmitter (Tx) and receiver (Rx) is the smallest value of throughput on the conditions Non Line Of Sight (NLOS) with Bluetooth 0.5 meters presence of interference against receiver laptop is 0.262 Mbps, and the biggest throughput value when the condition Line Of Sight (LOS) without the bluetooth is 6.107 Mbps. Throughput values obtained from the jitter and delay and delay jitter is the largest in NLOS conditions when there is interference at a distance of 0.5 meters bluetooth to laptop recipients are 3.0534 s and 2.7481 s.
