A Study on the ZigBee Wireless Communication for IAQ Monitoring of Underground Subway Stations

In this paper, the 424MHz ZigBee module, which uses a relatively lower frequency for wireless transmission and reception, is found to have a much higher data transfer rate than that of the 2.4GHz XBee PRO in the presence of obstacles such as subway waiting rooms, platform like stairs, complicated structures, and crowded passengers. This indicates that low frequency radio waves have better diffraction characteristics and thus better performance in face of obstacles. Therefore, it was found that low frequency Zigbee modules are advantageous in areas with complex structures such as subways.
