摘要

互联网的快速发展已经使其成为连接世界人民的流行媒介。伴随着互联网流行而兴起的无线技术,由于广泛的需要迅速为人们所接受。无线应用协议或WAP是一种应用程式,使人们通过无线网络,从手机、PDA或任何其它便携式设备访问Web。 本文在已有的有关WAP的研究工作基础上,如WAP的功能、使用、结构、以及WAP与其它应用的结合等,主要在以下方面展开探讨: 1、分析WAP的架构,以此学习WAP的不同结构层次和每层所起的作用及具体功能。 2、分析嵌入式WAP服务器的工作原理及功能。 3、分析WAP与蓝牙的结合。剖析它们各自不同的特点,研究两者相结合后创造出的更多功能。 4、剖析建立和使用WAP的受益者。探讨从生产商、运营商到普通用户,各个群体的受益情况。 研究表明,许多人因使用WAP而受益。无线应用架构和嵌入式WAP服务器在建立和运行应用程序中起着重要作用的。单独使用WAP或蓝牙技术有众多的限制,但当结合在一起时,为无线通讯技术打开了—个崭新的大门。不仅只是互联网和移动电话,而且还有其它设备,已经深刻地影响着我们的日常活动。
