METHOD FOR CALIBRATING AN ON-BOARD UNIT AND A TEST DEVICE, A METHOD FOR WIRELESS TOLL COLLECTION
摘要：
A method comprises: disposing an on-board unit at a preset relative position with respect to a road-side unit; transmitting a signal by the road-side unit; receiving the signal by the on-board unit and detecting a strength of the received signal; calculating, by the on-board unit, a calculated strength of the received signal according to the detected strength of the received signal; storing the calculated strength of the received signal in a memory accessible by the on-board unit; using the stored calculated strength of the received signal to determine if payment of a toll should be made.
摘要（中）：

一种方法包括：将车载单元布置在相对于路侧单元的预设相对位置; 通过路侧单元发送信号; 通过机载单元接收信号并检测接收信号的强度; 根据检测到的接收信号的强度，由车载单元计算接收信号的计算强度; 将计算出的接收信号的强度存储在由板上单元访问的存储器中; 使用存储的所计算的接收信号的强度来确定是否应该支付费用。
