说明：  近年来，移动通信技术发展迅速，新技术层出不穷， 宽带无线接入技术由于具有网络设计灵活、安装迅速方 便、建设速度快、建设造价低廉等突出的优点，在高速因 特网接入、信息家电联网、移动办公、军事、救灾、空间 探险等领域具有非常广阔的应用空间。根据目前的技术 标准和将来的发展，主流的宽带接入技术可以分为：固定 宽带无线接入技术（FBWA）、无线局域网（WLAN）和无 线个域网（WPAN）。其中无线个域网的发展使得人们摆 脱电缆束缚，在近距离内实现各种设备间的通信的梦想 得以实现。基于ZigBee 无线接入技术的WPAN 更以其低 成本、低功耗等特有的优势成为无线接入领域的又一颗 璀璨的新星，给现代信息社会中人们的工作和生活方式 带来一场新的革命。
(In recent years, mobile communication technology is developing rapidly, the new technologies have Broadband wireless access technology because of network design flexible, speedy and convenient installation, construction speed, construction of low cost highlight the advantages of high-speed Internet access, information appliances, networking, mobile office, the military, disaster relief, Space exploration and other areas with a very wide application of space. Under the current technical standards and future development, the dominant broadband access technology can be divided into : fixed broadband wireless access technology (FBWA) Wireless local area network (WLAN) and Wireless Personal Area Network (WPAN). Which WPAN development and enabled people to escape from cable restraints, In all wi)
