The Internet of Vehicles has become the development trend of the automobile industry, and the penetration rate of the Internet of Vehicles is constantly increasing. According to IHS estimates, by 2020, the global automotive electronics market will be close to 300 billion US dollars, and the market space is huge. From the product level, in the past 10 years, the application of automotive electronic products has mainly focused on the power system, chassis, body, etc.; network connection. At this time, the coordination of GPS, sensors and communication modules has become the key.
As an industry-leading wireless communication module company, SIMCom is committed to providing stable connections and excellent user experience for the majority of car owners. The wireless communication module provided by SIMCom is the core component in the vehicle-mounted telecommunication terminal, the pipeline connecting the vehicle and the network, and the beginning of the user experience. Without a wireless communication module, car-related in-vehicle applications cannot be connected to the Internet, that is, the Internet of Vehicles cannot be realized. In the future, after the application of mobile edge computing and 5G network in the Internet of Vehicles, the data of the Internet of Vehicles can be stored in a location close to the vehicle, providing low-latency and high-reliability communication capabilities, and performing data analysis in real time, and analyzing the results. Quickly communicate to other connected vehicles in the immediate area for vehicle decision-making. SIMCom’s SIM7800 automotive-grade module connects the center console and the Tbox, and the Tbox is connected to the outside world to realize a new interconnection or entertainment experience with large traffic in the connected car environment.

SIMCom SIM7800 is an automotive-grade module based on Qualcomm MDM9628 LTE CAT4. It is packaged in LGA and has a size of 34*40*2.9mm. The maximum downlink bandwidth can reach 150Mbps and the uplink bandwidth can reach 50Mbps. SIM7800 is based on a new network security design and complies with automotive network security architecture standards. SIM7800 uses multiple security mechanisms to ensure the security of communication between cars and the Internet, providing OEMs and users with smart in-vehicle solutions. The SIM7800 module is a vehicle-grade module that provides software development kits and software secondary development solutions. The open linux solution provided can stimulate the creative potential of developers. It also provides built-in network security functions and supports safe over-the-air upgrades. . The SIM7800 reserves a high-speed Ethernet interface, which is suitable for high-speed data transmission in the vehicle and provides stable and reliable communication capabilities for the vehicle.

Nicola Chen, product manager of Excelpoint, a SIMCom agent, said: “The Tbox custom development board will help designers flexibly use SIMCom’s automotive-grade module SIM7800 to provide automotive users with more abundant business and services, and to Vehicles are effectively supervised and dispatched to achieve more efficient, safe and comfortable vehicle management and user experience.”
Safety is the top priority of the Internet of Vehicles. Strictly controlling the absolute security of the connection between Tbox and the external network is an important task of SIMCom. First of all, in terms of program protection, only products from legitimate sources can upgrade Tbox. Second: In terms of system security of the module, since it is based on Linux, SIMCom uses SeLinux+ to block all the ways of illegal intrusion. Third: protect the privacy of files and encrypt data.
