Car built-in LTE will become the general trend. Audi and General Motors have successively announced that their vehicles will have built-in LTE communication systems to achieve advanced functions such as seamless audio and video streaming, real-time navigation and vehicle safety protection. Attitude will drive the wave of LTE in connected cars.
The 4G long-range evolution plan (LTE) will become the standard equipment of the Connected Car in the future. General Motors (GM) announced at the 2013 Mobile World Congress that it will work with American telecommunications provider AT & T to provide in-vehicle LTE services, and introduced LTE communication modules to its vehicles in the United States and Canada in 2014 ( figure 1).

According to Mary Chan, vice president of GM ’s Global Connect Customer Division, after the LTE communication module is built into the vehicle, TelemaTIcs is no longer just a consumer who uses his handheld device to connect to the vehicle ’s electronic system. On the contrary, the vehicle itself has already Become a smart mobile device, this will make more smart vehicle functions come true.
With the support of LTE communication modules, OnStar will provide new infotainment services such as video streaming in the rear seats, real-time information updates and faster applications. Program download speed.
According to GM official information, the built-in LTE communication module is special in that it is integrated into the vehicle's own electronic system and includes an external antenna to maximize the service coverage area and connection capacity, so consumers do not need to Limited to the communication function of the smartphone, you can get the connection service.
LTE blessing seamless video streaming comes true
In the past, most vehicle-mounted telematics systems could only provide functions such as road rescue, navigation, and emergency call. However, after Audi and General Motors successively introduced LTE communication modules to their products, the function of vehicle-based telematics is expected to be more complete, and consumers can always Get smooth real-time audio and video streaming, entertainment information and other services to welcome the era of seamless networking.
It is reported that observing the changes in the overall vehicle telematics market from 2012 to the present, it can be found that the major brand car manufacturers are striving to move forward in the two directions of popularization of networking and intelligent vehicles. The former connects vehicle-to-vehicle (V2V) or vehicle-machine and smart handheld devices through wireless local area network or Bluetooth, or even 3G or the latest 4G LTE communication network; the latter uses vehicle-mounted data The expansion of communication application (App) services provides consumers with more diversified functions.
In fact, since the transmission speed of LTE is ten times higher than that of 3G technology, after the built-in LTE system in the car, the vehicle-mounted telematics system can provide users with uninterrupted voice, data connection services, and more in-vehicle infotainment, Real-time audio-visual news, Wi-Fi hotspots, and past driving is limited to the transmission speed, can only use fixed-point navigation, and in the case of a large increase in LTE bandwidth, you can also upgrade to real-time navigation, to provide additional protection for driving safety.
Car LTE module out of the cage
To meet the new wave of business opportunities for automotive LTE systems, chip vendors and module vendors such as Telit, Gemalto, and Huawei have launched LTE chipsets and communication modules at the end of last year or this year's MWC. Market opportunities.
Telit opened its first shot at the end of October last year and announced that it will launch LTE cellular modules for European and North American automotive original equipment manufacturers (OEMs) and the aftermarket. The module has a download speed of 100Mbit / s and 50Mbit / s Upload speed, and supports Evolved High-Speed ​​Packet Access (HSPA +), Global System for Mobile Communications (GSM), and Global Packet Radio Service (GPRS) to ensure that the system can still provide basic driving communications even when 3G and 4G networks are inoperable service.
Gemalto and Huawei launched vehicle LTE infotainment system connection technology and LTE communication module respectively during MWC.
It is understood that under the support of Gemalto ’s LTE connection technology, the vehicle-mounted telematics system allows users to enjoy voice and data services, navigation of real-time street video data, multimedia video streaming and download, and support for up to eight devices. Mobile Wi-Fi hotspot. In addition, when the LTE network fails, the connection technology will maximize 3G speed to meet the demand for automotive networking in harsh environments.
At the same time, Huawei also released the vehicle regulation LTE communication module at MWC, which can provide a download speed of up to 100Mbit / s for the vehicle-mounted telematics system, while supporting the global satellite positioning system (GPS) and emergency call (eCall) functions.
As can be seen from the above, LTE for vehicles has become a huge business opportunity targeted by major manufacturers and is expected to become the standard equipment of connected cars in the future.
GM and AT & T will focus on R & D for 4G LTE connectivity in North America and Canada. AT & T estimates that by the end of 2014, its LTE network users will reach 300 million.
In fact, Audi, another major brand car manufacturer, has repeatedly emphasized the development potential of automotive LTE communication at the 2012 US Consumer Electronics Show (CES), and first announced that it will adopt Qualcomm (Qualcomm) at this year's CES. The 3G / 4G LTE multi-mode chipset is built into the A3 model and is expected to provide LTE services this year.
It is not difficult to find that LTE can provide users with more additional functions for vehicles than 3G technology in the past. It is an ideal choice for car manufacturers to add value to their products.
1.The heat transfer rate is up to more than 90%, saving energy and
electricity
2. The honeycomb circuit has planar heating, and the effective
heating area accounts for a large proportion, about 60% of the
product area, and the heated object is heated more evenly
3. Radiate far-infrared light wave, making the heat source softer
4. Wide circuit and connected design, no need to worry about
crimping the circuit break
5. Add the thermostat protection device, which can ensure the
product safety under bad conditions and effectively prevent the
superhigh temperature of the object being heated
