Anyone who has used the automotive lte 4g tracker manufacturer knows that in order for a device to work properly, a SIM card must be configured in the device and the card must be activated for normal use. Why is it necessary to have a SIM card in the lte 4g tracker manufacturer to position and track the vehicle? It's not hard to understand, just know the positioning principle of the lte 4g tracker manufacturer.

What is the lte 4g tracker manufacturer?

The lte 4g tracker manufacturer is a terminal with built-in GPS module and mobile communication module. It is used to transmit the positioning data obtained by the GPS module to a server on the Internet through the mobile communication module (gsm/gprs network). In this way, the terminal location can be queried on the computer or mobile phone.

Car gps positioning principle:

After reading the above content, you already know the positioning principle of the lte 4g tracker manufacturer. The GPS module in the device receives the data sent by the GPS satellite, and then the data is transmitted to the server through the GSM/GPRS network for analysis, after the analysis of the longitude and latitude, height, speed, time and other information of the geographical location of the vehicle comes out, we can view the location of the vehicle on the mobile phone or computer.

Does the lte 4g tracker manufacturer work without a SIM card?

According to the lte 4g tracker manufacturer positioning principle, the locator obtains satellite signals to calculate the latitude and longitude, and then upload the latitude and longitude to the server through the network. The server analyzes the specific location, and then people query the location of the locator from the server through their mobile phones or computers. Without a sim card, the latitude and longitude of the device cannot be issued, and you cannot query the location of the device. Therefore, an lte 4g tracker manufacturer without a sim card does not exist.

Therefore, why should the car GPS be configured with a SIM card? It is clear that it is to transmit data. If the SIM is out of charge or cannot be used for other reasons, the device will be displayed offline on the monitoring platform. In addition, some GPS positioning devices have a monitoring function, which can be monitored by dialing the phone number of the SIM card on the device.
