越区覆盖可以利用CNA的All TD-LTE Cell Coverage进行测试路线上的全部小区（）进行判断。

如果cell1是cell2的相邻小区，则cell2必定是cell1的相邻小区。（）

无线网络优化项目工作的启动阶段的工作内容不包括（）

单站验证测试的目的是在RF优化后，保证待优化区域中的各个站点各个小区的基本功能均是正常的。（）

在无线网络安全机制WAPI中，（）实现通信数据的加密传输。

Routers perform the decision process that selects what path a packet takes. These （ ） layer devices participate it the collection and distribution of network-layer information, and perform Layer 3 switching based on the contents of the network layer （ ） of each packet. You can connect the routers directly by point-to-point （ ） or local-area networks, or you can connect them by LAN or WAN switches. These Layer 2 switches unfortunately do not have the capability to hold Layer 3 （ ） information or to select the path taken by a packet through analysis of its Layer 3 destination address. Thus, Layer 2 switches be involved in the Layer 3 packet （ ） decision process.

目前，网络攻击的途径逐渐延伸向无线网络和移动终端

TCP functions at the Open System Interconnection(OSI)(61)layer, or Layer 4. Its chief responsibility is to ensure(62)end-to-end connectivity. IP, located one layer down, at the OSI network layer, or Layer 3, communicates the addresses of each(63)sender and receiver to the routers along the way. Routers and Layer 3 switches can read IP and other Layer 3(64). This information, combined with routing tables and other network intelligence, is all it takes to get(65)the room or around the world via TCP/IP.

A是LAYER1小区，B是LAYER2小区，A-B是互为邻区，以下哪个描述是错的？（）

移动通信设备的网络测试可以通过()实现。

蜂窝移动通信是采用（）组网方式，在终端和网络设备之间通过无线通道连接起来，进而实现用户在活动中可相互通信。

（）负责和本小区内移动台之前通过无线电波的方式进行传输。
