摘　　要：目前,全球宽带通信市场发展迅速,无线化成为宽带接入的未来发展方向。提出在发展无线接入时需注意的若干问题。当前移动接入与固定接入的界限正逐渐变的得模糊,认为统一的标准有利于推动无线接入技术的发展,而且任何宽带无线接入技术必须支持话音业务。接下来剖析了WiMAX的发展情况,分析了WiMAX与3G的关系。最后提出应重视短距离低速率无线接入系统的发展。At present, global broadband comunication market develops fast, and wirelessness becomes the development trend of broadhand access. This article ruddy puts forward several problems in the development of wireless access. Curcently the boundary between mobile access and fixed access becomes ambiguous, and unified standard can enhance the development of wireless access technology. In addition, all the broadband wireless access technologies must support voice services. Then it analyzes the status quo of WiMAX and the relationship between WiMAX and 3G. Lastly, it stresses the importance to develop die shortdistance and low-rate wireless access system.
