The Internet of Things (IoT) experienced rapid development in the 10 years from the concept to the current one. There are many means of connection such as wired and wireless, ranging from centimeters to transnational levels. In recent years, operators have also conducted in-depth deployment in the Internet of Things industry. Among them, the most promising is the Low Power Wide Area Network (LPWA). Looking from the future trend, NB-IoT and eMTC will become the important technology that carries the operator LPWA network. As a comprehensive solution provider for mobile communications, Datang Mobile is actively deploying the above two technologies in an effort to help operators win all-in-one opportunities. NB-IoT and eMTC are the key technologies of the operator LPWA network In the carrier LPWA network, NB-IoT's typical application scenarios are smart meters, smart parking, municipalities and the environment, such as low-speed, wide coverage of the scene. In these scenarios, NB-IoT has the advantages of low power consumption, wide coverage and low cost. For example, on the power consumption, a battery can be used for 10 years; in coverage, it can be 20 dB higher than the 2G network with strong coverage capability, and the signal can penetrate more than one wall; in terms of cost, the organization predicts that a single Module prices will reach $ 2 per unit in future large-scale applications, which means that an NB-IoT access point can support a decade online with about $ 14. The typical application of eMTC is school information, lift guard, logistics tracking, driving guards, wearable devices and other mid-range speed class and low-power large connected applications. In the eMTC application scenario, the network rate is less than 1 Mbps, which supports voice (VoLTE) and mobility management, and covers 15 dB more than LTE. The difference between this technology and other IOT technologies is not only reflected in its ability to support voice services. It also retains the network's mobility management capabilities to meet the needs of mobile terminals. Datang Mobile with active technology to actively expand the field of Internet of Things Datang Mobile based on perennial accumulation in the field of basic communications to the field of things and chip modules chip has been expanded to provide accelerated industrial floor to provide a simple connection services based on minimal module supply and improve platform integration capabilities to provide applications End-to-end communications solutions. Mentioning the Internet of Things basic technology, Datang Mobile in network technology, terminal technology and application of business in three areas have a strong lead. On the communications network side, Datang officially started the development of IoT business capabilities of public network equipment in March 2016 and supports two basic technologies, NB-IoT and eMTC, in the LTE system (including TDD and FDD). As of the end of 2016, it has completed the product and software features support for dual-mode FDD + NB-IOT and also participated in the software and hardware basic functions testing of two operators' organizations, China Mobile and China Unicom, and took the lead in completing the UL3 .75 K +15 K two rate support. At the same time, Datang Mobile has also developed a core network for the IoT business, completed the development of most of the base station technologies and completed a complete technical reserve for commercial IoT services in the carrier network in 2017. Terminal technology, Datang Mobile and actively promote the cooperation with chip makers, and Qualcomm, Intel, Spreadtrum three mainstream chip business cooperation and actively with emerging chip manufacturers for technology interoperability, completed the chip development phase of the Interconnection Tune, to support the most basic industrial communication capabilities. At present, Datang Mobile has already been able to deliver IoT terminals for 2G, 3G and 4G existing mobile communication markets on a large scale, including multi-mode, single-mode, CAT1, and multi-interface IoT communication terminals. In terms of application business, Datang Mobile partners in joint application areas and operators covering basic services jointly promoted the rapid promotion and implementation of the Internet of Things. In the basic business areas, Datang Mobile has deployed Internet of Things (IoT), Internet of Things (IoT), Internet of Things (IoT), and the Internet of Things (IoT) into three major areas, including Internet of Things, smart cities and other comprehensive areas. In the field of agriculture, Datang Mobile conducted product research and development in basic fields and promoted pilot projects based on the NB-IOT application in various places. In the industrial area, Datang Mobile has been trying to cooperate with a number of enterprises and conducted extensive exploration in such fields as smart manufacturing and smart pipe network. For the future car networking business, Datang is also actively promoting the industrialization of LTE-V landing. In addition, Datang Mobile also made a corresponding layout in terms of IoT security and developed a common security encryption solution based on NB-IoT technology, including the encryption chip dedicated to the Internet of Things, the encryption and decryption algorithm adapted to NB-IoT, the self-controllable operation System and platform solutions. To create from the terminal to the network to the platform of the entire link, trusted, controllable, secure and secure IoT system. For some special areas, such as special asset tracking, Internet finance, security monitoring, intelligent factories and other network environments to provide higher and more levels of security mechanisms. As time goes by, operators 'IoT has come to the standard from the standard. With the joint support of industry partners, operators' LPWA IoT based on licensed frequency band has become an undoubted global trend. Datang Mobile will rely on the profound accumulation in the field of communications, for the entire industry thriving to provide strong technical support.
