According to foreign media reports, today's vehicles have as many as 100 computing units, and the software code is up to millions of lines. In order to ensure that the vehicle digital network and vehicle software are in the latest version, the owners often have to drive the car into the repair shop to complete the upgrade of the vehicle network and software. Nowadays, the mainland solves this technical problem for global car companies. The company has launched an aerial download technology solution, which can upgrade and maintain the in-vehicle software, covering a wide range of fields, from powertrain to in-vehicle infotainment systems. Within the scope of its services.

Establishing interconnection and cooperation
To this end, the mainland has further expanded its vehicle networking related product portfolio. The mainland has partnered with Carnegie Technologies to leverage Carnegie's technology platform to ensure that the vehicle network connections used by car owners and drivers are always up to date, providing the fastest and most reliable network service. Carnegie Technologies is a leading global provider of wireless networking solutions.
According to the agreement signed by the two parties, the mainland is reselling Carnegie Technology's Network Convergence Platform and integrating it into the mainland's Smart Telematics, which serves the car. Enterprise.
When the vehicle is driving on the road, the technology can provide users with bandwidth aggregation, seamless transfer of phone and data, fast and seamless switching between wireless networks, LTE, 3G and satellite networks. These new features will play an important supporting role in the automatic download and upgrade of the in-vehicle software.
Smart software for seamless connectivity
As an important part of the mainland's intelligent in-vehicle information portfolio, Carnegie Technologies' intelligent software solutions will continuously scan and measure the available networks, while confirming the bandwidth requirements of the vehicles, and then automatically aggregate the network for users. Provide the fastest, most reliable and cost-effective network connection. In addition, the program also provides the VehicleLink function, which uses the devices such as smartphones, tablets and laptops to obtain the vehicle bandwidth, thereby controlling the data cost and providing users with the best connection solution. The above functions can also be implemented if external wireless is available.
Carnegie's Gapless Handover enables the mainland's intelligent in-vehicle information system to continuously stream data. When the cellular network signal becomes weak, users can use the wireless hotspot provided by another network provider to automatically switch the data stream of the smartphone to the most cost-effective data provider. If the network connection is temporarily unavailable (for example, when the vehicle enters the tunnel), the call will remain active until the network connection is re-established to ensure the persistence of the session.
The car company will fully control the timing and mode of bandwidth aggregation and seamless transfer. They can decide which applications can use the embedded mobile network solution, thereby preventing in-vehicle applications from accessing unsecured networks or setting other parameters and usage rules. For example, the use of media sync will be limited to home wireless network connections, and passengers' tablets will be limited and must not access the embedded mobile network. The car companies will also set up video conference calls to enable switching between embedded LTE, wireless networks or satellite networks to avoid network outages.
Reliable, efficient and cost-effective satellite communication service
In addition to data-intensive applications, the mainland is working with mobile satellite communications company Inmarsat to implement an over-the-air upgrade service via satellite communications, which is currently under development. After adopting the global satellite network of maritime satellites, the mainland will provide its customers with remote upgrade services for vehicles, which can easily run global upgrade services no matter where they are, without having to deal with many different mobile network operators at the same time. Significantly reduces the complexity of the operation.
The mainland relies on satellite network communication provided by maritime satellites to implement software upgrades. The company uses a single network to achieve global over-the-air upgrades. The number of connected vehicles in the world is continuing to grow, and this trend has increased the frequency of upgraded services, requiring a scalable global technology solution. The maritime satellite is responsible for the operation of multiple geosynchronous satellite constellations, which can help to achieve global download and upgrade services for vehicles, with fast service, timely response and high efficiency.
Users of the mainland can experience global upgrades at the push of a button, eliminating the need to face multiple network operators, making upgrades easier and easier. The cooperation between the mainland and maritime satellite enables vehicles to use intelligent routing, flexible use of satellite networks and terrestrial networks (mobile mobile networks, wireless networks), allowing users to spend the least amount of money, using the best quality services, will serve Usability is at its best.
Antenna, vehicle information system and gateway: the architecture of the entire network connection
The smart antenna provided by the mainland or the independent vehicle information system can help the vehicle to realize the network connection, and the gateway is the medium between various network domains in the vehicle, which serves as a communication route.
The above devices can be centrally connected to all on-board communication buses and enable access to all relevant information. As a result, they will provide the required over-the-air upgrades for the infrastructure and distribute them to the relevant electronic control unit. The gateway can transform the pure information routing into a central network interface, provided that the network device is directly integrated into the gateway.
USB Cable :1.Type A: almost every USB cable has a standard flat rectangular interface at one end. Most computers have a usb-a port to connect to only one USB port.
2.Type-B: almost square connector for printers and other active devices connected to computers. They are not common now because most devices have been moved to smaller connections.
3.Mini USB: a smaller connector type that was standard for mobile devices before micro USB. It's not common today, but you'll see it on some cameras, PlayStation 3 controllers, MP3 players, etc.
4.Micro USB: the current standard for mobile and portable devices, even smaller than Mini USB. Although you can still find micro USB on smartphones, tablets, USB battery packs and game controllers, some have turned to usb-c
5.Type-C: the latest USB standard, which is a reversible cable, promises higher transmission speed and higher power than previous USB types. It can also take into account a variety of functions.
