Opportunities and challenges of M2M communication in automotive electronics applications

Relying on huge market opportunities, M2M has become another important frontier in the field of mobile connectivity. As one of the first areas where M2M is put into commercial use, M2M communication applications in the automotive transportation market have long been widely developed. With a cellular wireless transceiver installed in mobile assets such as trucks, buses and heavy equipment, the management back office exchanges bi-directional data with the vehicle and monitors vehicle location, travel time, fuel consumption and maintenance status anytime, anywhere. In particular, we invite Mr. Shen Jianguo, General Manager of the Module Business Unit of Xuntong Wireless Technology (Shanghai) Co., Ltd. to share with you the opportunities, challenges and solutions that may exist in specific applications.

M2M communication market trends and demand trends

The global M2M market has maintained a shipment growth of more than 20% in recent years. According to market research firm ABI Research, shipments to the global M2M market will reach 56 million in 2012. Since 2002, SIMCom has maintained an average growth rate that exceeds the industry average. Although the financial crisis has greatly slowed the growth rate of M2M, its growth has not diminished.

M2M application scenarios are increasing, from industrial application scenarios to family, community, school and mobile scenarios. With the rise and implementation of the concept of IoT, it is expected that these applications will be more broad, and M2M will maintain strong growth in the next few years. With the Chinese government and industry's emphasis on the Internet of Things and the vigorous promotion of the industry, we expect the domestic market M2M and the Internet of Things industry to greatly exceed the growth rate of the global market.

From the demand of M2M for wireless communication modules, customers require module suppliers to provide powerful, stable, reliable, multi-module module products, and require module suppliers to provide more comprehensive design services and technical support.

The development of emerging automotive electronics applications currently faces challenges and risks

The automotive electronics industry application is a major direction of M2M applications. The automotive electronic application environment is much worse than other M2M applications. It has strict requirements for high temperature resistance, vibration resistance, shock resistance, radiation resistance and antistatic performance of the terminal products. At the same time, the industry has strict system certification for the vehicle terminal product suppliers. Claim.

Current communication electronic chips can basically meet the general M2M applications, but for upstream chip manufacturers and module manufacturers, more reliability tests are needed to screen and ensure that the final products meet the requirements of the automotive industry.

In fact, the wireless communication module has long been used in the automotive industry for many applications, such as taxi/bus dispatch management, logistics industry vehicle management, bus private car theft tracking, dangerous goods transportation tracking and so on. Our in-vehicle modules are also used in a large number of applications. At present, the telematics for passenger cars/private cars that are gradually emerging in China is also a direction we focus on and participate in.

SIMCom solutions help customers address these challenges or risks
