碩士 === 國立臺北科技大學 === 電腦與通訊研究所 === 99 === The IEEE 802.15.4 standard, IEEE 802.11b and Bluetooth coexist on the same network and which the standard developed and set up by IEEE. To comparison of the performance and the channel interference analysis with 2.4 GHz under the protocols. This study used two laptops to do a platform with WLAN and Bluetooth,and ZigBee used the Super Node mdae by National Taiwan University to do a platform. In three different environments,thedevices are separated by two meters, to avoid ground interference devicesareat least 0.3 meter fromthe ground,WLAN fixed using channel 11 (2462 Mhz), Bluetooth uses version2.1, and ZigBee uses channel 11 (2410MHz)and channel 22 (2460MHz), similar tocoveredchannel and not covered channels and external disturbances to observe the PER and RSSI conditions. As the results when ZigBee and WLAN in thecoveredchannel, ZigBee''s RSSI falls approximately between -87.6dBm to-86dBm, PER at between 95%-97%; and not coveredchannel, ZigBee''s RSSI about-80dBm, PER is 5%. Therefore, use of equipment in the 2.4GHz communication band should be considerd the channel conflict.
