| 摘 要： | 目前,大量的无线设备应用在2.4GHz这一开放频段,很明显各种设备之间存在着潜在的干扰问题,在将来的办公或家庭环境中,如何避免或减少各种WPAN设备与WLAN的相互射频干扰变得日益重要。分析了分别由UWB、ZigBee技术构成的2种新型WPAN设备和WLAN之间的影响,分别从WLAN设备链路的吞吐量和信噪比(RSN)等角度分析了802.11bWLAN与2种短距离技术设备的干扰,并进行了WPAN设备的工程实验和模拟仿真。

| Abstract: | Recently, a number of wireless devices are sharing 2.4 GHz unlicensed frequency. Obviously, the problems exist that all kinds of devices have interference with each other. In the future, the issue how to avoid or decrease radio frequency interference between WPAN devices and WLAN will be more emphasized. In this paper, the inter-influence between two new WPAN devices using UWB and ZigBee technologies and 802. llb WLAN is analyzed. The throughput and signal-to-noise ratio of WLAN devices that affected by interference of WPAN are mainly illuminated, then the project practice and software simulation of the WPAN devices are carried out. |
