蓝牙技术是一种无线数据与语音、视频通信的开放性全球规范,它以低成本、近距离无线连接为基础,为固定与移动设备通信环境建立一个特殊连接。如果把蓝牙技术引入到移动电话和电脑中,就可以去掉移动电话与电脑之间的连接电缆,而通过无线通信完成数据传输功能。打印机、PDA、桌上型电脑、传真机、键盘、游戏操纵杆以及所有其他的数字设备都可以成为蓝牙系统的一部分。蓝牙的定位就是通信网络的最后10米。因此如何在高校运动中让教练员、运动员随时、随地可以使用各种设备,共享网络资源,自动采集比赛数据,访问校园网,是一个值得重视和研究的问题。解决这个问题简单易行的方法便是无线接入技术,其中蓝牙就是一种低成本、较理想的解决方案。
Bluetooth technology is an open global specification for wireless data and voice and video communications. It is based on low-cost, short-range wireless connectivity and establishes a special connection between fixed and mobile communications environments. If Bluetooth technology is introduced into mobile phones and computers, the connection cables between the mobile phone and the computer can be removed and the data transmission function can be accomplished by wireless communication. Printers, PDAs, desktops, fax machines, keyboards, joysticks, and all other digital devices can be part of the Bluetooth system. Bluetooth positioning is the last 10 meters of the communication network. Therefore, it is a problem worth paying attention to and how to let coaches and athletes use various equipments, share network resources, collect game data automatically and access campus network anytime and anywhere in college sports. The easy way to solve this problem is wireless access technology, of which Bluetooth is a low-cost, ideal solution.
