多数无线电技术使用模拟信号，而现代无线远程通讯使用数字传输。
While most radio technologies have used analog signals, modern wireless telecommunications are using digital transmissions.
规避这一问题的传统方法是让以相同频率通讯的无线电信号按顺序轮替传输，从而输出的信号就不会干涉输入的信号。
The traditional way around the problem is to have radios communicating on the same frequency take turns transmitting so the outgoing signal doesn't interfere with the incoming.
结论：基于蓝牙的无线通讯系统有接口简单、传输可靠的优点。
Conclusion: Bluetooth based wireless communication system has the advantages of high reliability and simple interface.
