1·Next up is backhaul, which is basically the connection between cell towers and the rest of the network.
下一个问题是回程，这基本上是指发射塔和网络的其余部分之间的连接。
2·There is also the option of a wireless microwave backhaul, but it requires cell towers that are in the same line of sight, and at some point the data still has to go wired.
我们也可以选择无线微波回程，但这必须保持发射塔在同一条视线上，而且在一些情况下数据必须通过有线网络传输。
3·There are three major constraints on streaming video to a mobile device over the air: wireless spectrum, backhaul, and the device itself.
把流媒体视频无线传送到移动设备存在三大问题：无线带宽、回程，以及设备本身。
4·Carrier Ethernet is the infrastructure being used to support mobile backhaul for next-generation, IP-based mobile networks.
电信级以太网是目前用于支持下一代IP移动网络移动回程的基础架构。
5·With auxiliary hardware, CX600 can provide the precision of time synchronization at a sub-microsecond level, fully meeting mobile backhaul requirements of various standards.
辅助硬件，CX600可以提供在亚微秒级的时间同步精度，完全满足各种标准的移动回程要求。
1·Its strong Operation Administration and Maintenance (OAM) -similar to SDH and carrier-class security protection services-ensure efficient mobile backhaul business management and transmission quality.
同时其类似sdh的强大运行维护管理(oam)及电信级保护能力保障了移动回传业务的高效管理及传输质量。
