众多支持者认为使用磁盘存储在线数据会产生很多问题，无法实现优雅地可伸缩性，而磁盘容量也会不断膨胀——访问延迟与带宽并非协调一致。

Proponents make the case that disk-oriented approaches to online storage are problematic, do not scale gracefully and while disk capacity has exploded — access latency and bandwidth has not kept pace.

诸如EVDO和HSPA这样的移动技术能够利用协调的有保证的带宽提供宽的覆盖范围；而想WIFI这样的技术提供高的带宽和低的等待时间。

Mobile technologies such as EVDO and HSPA provide wide area coverage with consistent bandwidth guaran - tees; while technologies like WiFi provide high band - width and low latency.

仿真表明，通过该方案设计得到的控制器，可以保证系统的稳定性，而激光通信控制系统的粗、精回路具有合适的系统带宽，可以协调地工作。

The simulation proves that the controller achieved through this scheme is able to keep system stability and provide proper system bandwidth to both coarse and fine loops for their coordination.
