毕业设计 短距离无线通信数据传输方法的研究 摘 要 随着网络及通信技术的飞速发展，人们对无线通信的需求越来越大，各种短距离无线通信技术将在自动化控制和家庭信息化领域扮演越来越重要的角色。对这些短距离无线通信数据传输方法的发展必将更好地服务于人们的工作和生活，使通信变得更为便捷。 本文主要研究几种常见的短距离无线通信数据传输方法，对目前使用较广泛的蓝牙、802.11系列无线局域网、UWB、HomeRF和红外传输技术UWB的实现方法，并对的应用进行了展望。WB 红外  ABSTRACT With the rapid development of network and communication technology,the wireless communication is more and more increasingly for the people.all the kind of short-range wireless communication technology will play a more and more important part in the automation control and the region of home information.The method of data transfer should service which people’s work and life better for these short-range wireless communication,at the same time,it is quite convenient for the correspondent. The thesis mostly research the method of data transfer which some kind of common short-range wireless communication.and expound the transmission technology which used more widely of the Bluetooth,ieee802.11 series wireless local area networks,uwb,homerf,zigbee and infrared for the moment,to further analyses and compare their relative merits and implementation method clearly,the technical of similarities and different point,it has been reviewed the selection and use of these technologies should be noticed.To further investigate the new wireless technology standard uwb which have the development potential method.
