| Abstract: | It is a troublesome matter for a Zigbee designer that using the general wireless channel model to estimate transmission distance results in lager errors. By the 802.15.4a channel model, the analytical methods of 2.4GHz Zigbee RF module radiation transmission loss is discussed; the factors that affect the transmission distance are analyzed, and the estimation formula for the maximum transmission distance is derived. For the Zigbee RF module specific circuit designed, the transmission loss and the largest transmission distance are calculated and through the experimental test, the estimated error is less than 10％, which is in line with the requirements of engineering applications, and it can be used as the theoretical basis for 2.4GHz Zigbee RF module design and engineering applications to estimate the transmission distance. |
