In 2015, 3G networks matured, 4G networks developed rapidly, and 2G network business volume and utilization ratio continued to decline. Global operators began to gradually shut down 2G networks and promote the evolution of LTE module /M2M module formats to 4G to improve spectrum utilization . and reduce management costs.
From the domestic market, after the issuance of 4G licenses, the three major operators have launched active deployments. China Mobile is expected to build 1 million TD-LTE base stations this year, and the entire network population coverage will reach 85.4%; China Telecom is expected to build 1 million TD-LTE base stations this year. The completion of 470,000 FDD-LTE base stations overall conforms to the global market trend of switching from 2G/3G standards to 4G.
In fact, the development of the Internet of Things requires the support of long-distance and short-distance communications. This is because short-distance communication technology cannot cover the entire huge IoT application system. Many applications require wide area network communication or short- distance transmission wide area network gateways., especially for vehicles, which requires a large amount of running vehicle data and is not restricted by geographical location. Therefore, it is often used in OBD, smart rearview mirrors, smart car cameras, driving recorders, in -car Wi-Fi hotspots, etc. A built-in mobile communication module is required to collect and transmit data information.
Judging from ABI’s research, in the next three years, the reach of IoT applications will be fully extended. In-vehicle, smart grid, mobile payment, security monitoring, and remote monitoring and control will become the five largest long-distance M2M module shipments . fields. The emergence of 4G modules will accelerate the comprehensive development of long-distance applications. For example, in the power industry, China Power Grid has started bidding for 4G modules since 2014, and the proportion is gradually increasing. At the same time , as Internet cars continue to heat up, 4G network coverage covering a series of in-car Internet services such as entertainment, navigation, safety and vehicle diagnosis is becoming increasingly popular.
Foreseeing the development trend of long-distance M2M in the Internet of Things industry, some local module manufacturers have launched corresponding layouts in advance. As a wholly-owned subsidiary of ZTE Corporation, ZTE IoT has 13 years of module research and development experience and has many successful cases in many long-distance M2M applications such as power, vehicle, security, and mobile payment.
Wang Peng, deputy general manager of ZTE IoT in charge of module product operations, said that in State Grid Power, ZTE’s 3G module products have achieved 90% market share, and have reached 100% in the 4G standard. In addition, ZTE also provides Customized module products for some foreign customers such as Japan’s KDDI and Europe’s 450M smart grid. In the automotive field, ZTE’s early industrial-grade module products were used in the domestic automotive pre-installation market, and it developed the HSPA module MF226 for the European and North American OEM automotive markets. The full-band GSM/GPRS and EDGE ensured that in the absence of 3G coverage Network connections can still be achieved in local areas, providing reliable navigation and fast and accurate positioning. Later, in 2014, a car -grade module was launched for the vehicle pre-installation market.
At the same time, ZTE is also the first company in the Chinese market to invest in the research and development of let modules . Its related products have been commercialized and verified as early as 2010. Therefore, as the Internet of Things develops rapidly, ZTE will be committed to helping Solve the four major problems and challenges faced by the market: First, most IoT application markets require modules to have a life cycle of 5 to 10 years, especially the automotive and power markets; second, IoT applications require modules to have high fault tolerance to avoid data Loss and machine operation disorder; third, 2G/3G modules are gradually switching to 4G, but the Internet of Things still has a large number of low-speed requirements; fourth, individual Internet of Things applications with specific needs often require module manufacturers to provide industry-customized products.
Regarding the above issues, Wang Peng said that ZTE’s IoT module products cover all mobile communication standards from 2G to 4G, and can provide the market with general and customized module products. Many products have been mainstreamed in the United States, Japan, South Korea and other countries. Carrier certification, including AT&T, Sprint, Verizon, NTT DoCoMo, SKTelecom, etc. In addition, ZTE IoT focuses on the development of industrial-grade and automotive-grade module products, which have high fault-tolerance processing and backup mechanisms , and can support a temperature range of -40°C to 85°C to meet industrial-grade and automotive-grade applications with specific needs.
In addition to standard LTE communication modules, ZTE IoT has also launched innovative module products, such as extended modules (LTE Wi Fi) and smart modules (with its own operating system), which are well implemented in high-speed applications such as vehicles Low power consumption and low latency. In the face of a large number of low-speed application requirements for the Internet of Things, ZTE has already made arrangements in advance, and the corresponding LTE Cat-1 module products will be available by the end of the year.
The above is the relevant introduction to the lte module , I hope it will be helpful to you!
