As the cost of both the radio devices and the air time drops, more and more measurement and reporting will be done with wireless networks.

随着无线电装置及发射时间两者成本的下降，越来越多的测量设备和报告将通过无线网络来完成。

But previous incremental update algorithms may be inefficient or cannot accomplish data update tasks when the wireless bandwidth drops dramatically.

但是，以前的增量更新算法在无线带宽急剧下降的情况下，会引起数据更新的效率下降或无法完成任务。
