                           4G LTE  Cat M1 GPS car  tracker TK319-L


The TK319-LTE (Cat M1 or Cat NB1 can be switched by software setting in
manufacturer before delivery) Tracker is a self-contained, integrated commercial grade
vehicle tracking device that uses GPS (uBlox IC embedded AGPS algorithm) satellite
location in combination with a complete, performance optimized, multi-mode and multi-
band LTE Cat M1/NB1 and EGPRS module of uBlox to report that location. This module
provides efficient and cost-effective high-speed mobile connectivity.

TK319-LTE acts like a LTE modem and responds to AT commands issued to it from
either a physical UART port connection or to AT commands issued to it through an SMS,
TCP/IP or UDP/IP connection. With regard to text messages, TK319-LTE “reads” all of
its own text messages and tries to interpret each message as an AT command. SMS text
may be sent to a TK319-LTE through any CSD SMS connection.

GPS Tracker Operating Principle:
There installed Satellite Receiver module and mobile phone module. GPS precise positioning with A-GPS and feedback position to the platform via GPRS at setting times(e.g. every 30s).It shows the precise position of the device on the map of platform. We need GPRS to transmit data, so the mobile phone with SIM card need the GPRS function.

Sample and mini order will be delivered within 1-2 working days after the receipt of payment.
For order over 500pcs or customized order, please contact our sales to make sure the current inventory. Our manufacturing capacity is 1,200,000 units per year. And for the popular units we hold 3000pcs stocks in advance per month.
