Performance of 2.4 GHz Xbee for Digital Image Transmission with Yagi Antenna

Abstract

The use of xbee modules is generally used for sending sensor data. In wireless communication today not only sensor data is sent, but also images that have a higher level of complexity. This study is used to determine the performance of xbee based on the IEEE 802.15.4 protocol for sending image data. Yagi antennas are used to strengthen or support XBee performance when shipping. The stages of the simulation were carried out with the 2016 CST software. The VNA preameter test produced yagi antenna parameters with a working frequency of 2.4 Ghz return loss = -12.27 dB, VSWR = 1.545. The results of sending a vertical image resolution of 160 x 120 obtain an average delivery time of 4.05 seconds, a speed of 678.28 bytes / second and data loss of 29% with the furthest distance of 250 meters. The results of sending vertical images of resolution 320 x 240 obtained an average delivery time of 11.24 seconds, speed of 779.28 bytes / second and data loss of 20% with the furthest distance of 200 meters. The results of sending a horizontal image resolution of 160 x 120 obtain an average delivery time of 4.03 seconds, a speed of 727.15 bytes / second and data loss of 20% with the furthest distance of 450 meters. The result of sending a horizontal image resolution of 160 x 120 obtained an average sending time of 11.19 seconds, a speed of 735.52 bytes / second and data loss of 23.8% with the furthest distance of 400 meters.
