Since the antenna of an ETC/DSRC OBE is usually attached in the car, the windshield needs to transmit a radio wave for communication. Therefore, when developing special automotive glass, such as heat-reflecting glass, you have to check whether a radio wave transmits.
Application
Since the antenna of an ETC/DSRC OBE is usually attached in the car, the windshield needs to transmit a radio wave for communication.
Therefore, when developing special automotive glass, such as heat-reflecting glass, you have to check whether a radio wave transmits.
Solution
- DSRC OBE tester ME9100 and DSRC communication unit ME9115CN are faced 1m apart. The glass to measure is arranged between them.
- Radio wave is transmitted from DSRC OBE tester ME9100. （Frequency : approx. 5.8GHｚ）
- Electric field strength is measured with DSRC communication unit ME9115CN. （Receiving range : -35 to -80dBmeirp）.
- By comparing the data with that of the reference glass used without problems ETC/DSRC communication, check whether the radio wave transmitted.
- Measured electric field strength data can be downloaded to a PC by connecting the USB cable.
