eMTC standard Both eMTC (enhanced Machine Type CommunicaTIons) and NB-IoT are in the new UE category of the LTE overall roadmap. Now LTE has begun to include cost and power reduction, so there is such a new UE Category. eMTC is Cat M1, and NB-IoT is Cat NB-1, which all belong to the same LTE development roadmap. These technologies can also coexist when operators deploy LTE, while EC-GSM is based on GSM (2G) technology. Some operators also have the original 2G network, hoping to use it to support the Internet of Things, and will continue to evolve on the basis of traditional GSM, adding enhanced features, such as deeper coverage. NB-IoT, EC-GSM and eMTC have different advantages. The NB-IoT and eMTC are based on LTE technology. The EC-GSM technology is mainly owned by established manufacturers such as Ericsson, Nokia and Siemens. Pushing, they hope that the Internet of Things field can continue its advantages in the GSM market, so it proposes a technical route for GSM upgrade to optimize EC-GSM. eMTC prospects The Internet of Things market has just begun. This trillion-dollar market cake, the piece based on the carrier network, is fermenting. Analytical agency data predicts that by 2020, the Internet of Things market will exceed $1.7 trillion. By 2025, global IoT devices will approach 70 billion, and about two-thirds of the entire Internet of Things will be in the LPWA field. Among the many technical areas of LPWA, NB-IoT and eMTC are both cellular Internet of Things. However, unlike NB-IoT, eMTC has certain advantages in terms of mobility, voice, and data rate, and can well support IoT services such as smart wear, vehicle management, and electronic advertising. According to the GSMA forecast. In the next five years, the cellular Internet of Things will grow sevenfold. By 2020, there will be about 3 billion connections carried over the carrier's network (of which 2.1 billion are connected to LPWA applications), industrial, personal applications, smart homes, public Business and many other aspects. China is currently the world's largest M2M market, with cellular M2M connections of approximately 100 million. By 2020, this number is expected to increase to 350 million. The LPWA technology will provide an additional 730 million connections, making the total number of connections more than 1 billion. In the next few years, China's Internet of Things industry will continue to develop rapidly, with an average annual growth rate of about 30%. In 2014, China's Internet of Things industry market scale was 600 billion yuan, reaching 750 billion yuan in 2015 and over 2 trillion yuan by 2020. Cellular-based eMTC is an important branch of the Internet of Everything. eMTC can well support IoT services such as smart wear, vehicle management, and electronic advertising, which will drive the development of the entire IoT market. eMTC advantage eMTC is a unified standard for the cellular Internet of Things established by the operation mall in the industry. The eMTC officially released in March 2013 in 3GPP R13 is designed to meet the needs of medium and low-speed IoT services. The LTE protocol is tailored and optimized, and the terminal works at 1.4MHz bandwidth. The main goal of eMTC is to achieve strong coverage, high capacity, low power consumption and low cost. eMTC has the advantages of anti-theft, anti-switching, real-time temperature sensing and locating in intelligent logistics. It can monitor and locate in real time, record and upload information, and query the driving track. In smart wearable devices, it supports health monitoring, video services, data backhaul and positioning. eMTC can also use the screen as a starting point to add value to operators' pipelines. These application scenarios include: smart charging piles, waiting treasures, elevator guards, intelligent bus stop signs, and public bicycle management. eMTC has the basic four capabilities of LPWA: One is wide coverage. In the same frequency band, eMTC has a gain of 15dB over the existing network, which greatly enhances the deep coverage capability of the LTE network; Second, it has the ability to support massive connections. One sector of eMTC can support nearly 100,000 connections; Third, lower power consumption, eMTC terminal module standby time can be up to 10 years; Fourth, lower module cost, large-scale connection will bring about a rapid decline in the cost of module chips, and the target cost of eMTC chips is around 1-2 dollars. eMTC's four major differentiation capabilities: First, the rate is high. eMTC supports the peak rate of up to 1Mbps for uplink and downlink, far exceeding the current rate of mainstream IoT technologies such as GPRS and Zigbee. The higher rate of eMTC can support more abundant IoT applications, such as low-speed video and voice. ; Second, mobility, eMTC supports connectivity mobility, and IOT users can seamlessly switch to ensure user experience; Third, it can be located. The TDD-based eMTC can use the PRS measurement on the base station side to perform position location without adding a new GPS chip. The low-cost positioning technology is more conducive to eMTC in the scenes of logistics tracking and cargo tracking. popular; The fourth is to support voice. eMTC evolves from the LTE protocol and can support VoLTE voice. It can be widely applied to wearable devices in the future.
