Communication module

1.The communication module supports China Mobile, China Unicom and China Telecom.

2.The terminal system is planned to adopt 4G network standard and needs to support 4G (TD-LTE, FDD LTE), 3G (TD-SCDMA, WCDMA), CDMA2000, 2G (GSM) standards.

3.The communication module can be connected to the service platform through the 2G/3G/4G data channel and the short message channel, and the communication protocol supports the application layer for encryption;

4.The external antenna interface uses a car-level Fakra interface.

Built-in battery

?1.The battery is a rechargeable battery with a service life of more than five years and meets the requirements of the car.

2.The terminal supports external DC power supply and supports internal battery power. When the external power supply is cut off, the built-in battery automatically supplies power seamlessly, and automatically switches to the external power supply after the external power supply returns to normal, and automatically charges the internal battery. The backup battery can ensure that the terminal works continuously for more than 5 minutes and has battery power monitoring function.

1. The built-in battery has a switching strategy circuit, and the terminal can ensure that the built-in battery fails and the external power supply can still work normally.

CAN communication

1.As a node of the vehicle CAN network, the terminal has the function of waking up the vehicle CAN network.

2.The terminal is connected to the CAN bus in the car and supports two CANs at the same time.

Positioning module

1.     Relying on different implementation methods, the terminal is equipped with GPS and Beidou antenna to support the function of obtaining the position of the vehicle. The terminal can be equipped with GPS/Beidou multimode antenna.

2.     See the parameter requirements (Table 2)
