This method will reduce the cost of target monitoring DGPS system, and simplify the target borne equipment to reduce the weight of the equipment.

使用位置差分法将减少目标位置监测系统的造价，使目标用户设备简单、造价低，而且重量轻（因为在军事上对于目标携带设备的重量要求往往很苛刻）

Because the technique uses off-the-shelf wireless transceivers similar to those used in home computer networks, "the cost of this system will be cheaper than existing methods of monitoring breathing, " says Neal Patwari, senior author of a study of the new method and an assistant professor of electrical engineering.

ENGADGET: Researchers use wireless network to monitor breathing, could save lives
