  • Product name: W-103 one-piece type OBU
  • 产品名称:
  • Code: W-103

  Wanji W-103 OBU is one piece type OBU; WanJi installed the chip RFIC (Radio Frequency Integrated Circuit) as well as RF (radio frequency), so the product can achieve stable and consistent performance. Furthermore, Wanji adopts integrated antenna design to ensure consistency of the heights of the two-way communication zone for radio frequency.

  The product adopts intelligent power management which all circuit module share one dynamic power supply. This design minimizes the product power consumption. Furthermore, the product has larger charging voltage which is 5.5V instead of the traditional 3.6V. The product also can maximize the solar power usage.  Finally, the product has longer service life because OBU adopt zero volt variance for battery charge.

  The OBU has three major advantages:

  Highly safety, Wanji embeds ESAM (Embedded Secure Access Module) and TDES (Triple Data Encryption Standard) in ETC to ensure data accuracy and transaction safety.

  Good directional adaptability, suitable for different installation angles and positions;

  Support data import/export with a hand-held read-write device.
