The transmittingdistance was shortened, as transmitting can not be performed with full power.
由于不能用全功率发射,发射距离缩短。
2
The portable or wearable device realizes these functions by periodically polling and receiving information tags within the transmittingdistance of the device.
便携式或可佩戴器件通过在器件的发送距离内周期性调查和接收信息标签而实现这些功能。

The system is supported by strict mathematics consequence, furthermore, the practical result indicates that the method provides high precision and the wireless transmittingdistance is long.
