Distinguishing from the former researches about CR service communication interruption, only spectrum handoff times exceed a certain number, communication interruption will occur. This strategy can reduce the COP of CR services.(3) Some coexistence issues between WRAN and DTV system are studiedFirstly, the network architecture, system parameters, and self-coexistence of Wireless Regional Area Network are investigated, and convergent performances among overlapping Base Station are simulated and validated. Then, a simple coexistent scenario between WRAN and Digital TV is designed to analyze the interference from WRAN BS to DTV receiver.

3研究了WRAN和DTV系统共存时的若干问题首先对无线区域网(Wireless Regional Area Network，WRAN)本身网络结构、系统参数和自共存机制进行了研究，仿真验证了WRAN重叠覆盖区基站(Base Station，BS)之间同步的收敛性能；接着设计了一种分析WRAN BS干扰数字电视(Digital TV，DTV)接收机的共存场景，通过研究发现了一些干扰控制的临界值，这些临界值对于WRAN的设计和部署具有指导性意义。

In regard to supplementary equipments, China Mobile has announced that the company will purchase all of antenna products, outdoor repeaters, optical fiber cable, power supply for switches, and air-conditions for base station from domestic providers; the company will also purchase most of the battery, feeder products, and small power generators from domestic providers.
