    • A Time Division Duplex (TDD) wireless system utilizes an identical TDD IC engine in both base station and remote stations. In the base station the clock input to the TDD IC is halted once in the middle of each time slice to provide a central guard band between transmit and receive portions that determines the maximum range of the system. At the remote stations clock halts are programmed and utilized to provide guard bands to position transmit and receive portions in each time slice to accommodate propagation delay based on separation of a remote station from the base station. In a preferred embodiment the remote stations determine range to the base and a controller programs clock halts based on the range finding. In one aspect a TDD IC engine is used with a minimum fixed central guard band and a time slice of a first duration at a first clock frequency. Clock frequency is increased and the clock halted to provide increased range at the same time slice duration. The same IC engine at the remote stations is operated at the higher frequency and clock halts used to provide the same time slice duration of the base station and to space the transmit and receive portions of the time slice properly to accommodate propagation delay.
    • 时分双工(TDD)无线系统在基站和远程站中都使用相同的TDD IC引擎。 在基站中,在每个时间片的中间停止向TDD IC输入的时钟一次,以在确定系统的最大范围的发送和接收部分之间提供中央保护带。 在远程站处,时钟暂停被编程并用于提供保护频带以在每个时间片中定位发射和接收部分,以适应基于远程站与基站的分离的传播延迟。 在优选实施例中,远程站确定到基站的范围,并且控制器程序基于距离寻找停止时钟。 在一个方面,TDD IC引擎在第一时钟频率下具有最小固定中心保护频带和第一持续时间的时间片。 时钟频率增加,时钟停止,以在相同时间片段持续时间提供增加的范围。 在远程站处的相同的IC引擎在用于提供基站的相同时间片持续时间的较高频率和时钟暂停下操作,并适当地对时间片的发射和接收部分进行空间以适应传播延迟。
