Abstract: With the application of nb iot chips, more companies about nb iot chips have emerged. This article lists several listed companies related to nb iot.
Nb iot related listed company - China TelecomAt the 2017 Tianyi Intelligent Eco Expo, China Telecom is expected to realize commercial VoLTE in the whole network in 2018. In addition, many technologies such as NB-IoT and eMTC will realize commercial applications simultaneously.
At the Tianyi Exhibition, China Telecom from the M-IoT chip module to the platform application, from the smart city, vertical industry to personal consumption field, concentrated display, M-IoT ecosystem formed. At the Tianyi IOT Industry Alliance Summit Forum, China Telecom announced 12 IoT warehousing modules, including 6 NB-IoT modules and 6 Cat.1 modules. At present, the number of members of the Tianyi IOT Industry Alliance has increased from 95 to 177.
The Tianyi IOT Industry Alliance's solution library covers 40+ IoT scenarios, involving smart cities, transportation and logistics, industrial energy, healthy homes, agro-ecology, and financial industries. Among them, the alliance member Huizhong Instrument completed the NB-IoT smart water meter pilot in Shunde; Zhejiang Jinka NB-IoT smart gas expanded the pilot number in the three places to reach 1,000 units, Ningxia Auto NB-IoT cow monitoring in Heilongjiang, Inner Mongolia, Ningxia And piloting four provinces in Xinjiang.
Shen Shaoai, deputy general manager of China Telecom's technology department, said that China Telecom's network coverage based on 800M NB-IoT has an absolute advantage in the world. She believes that the application of the Internet of Things is fragmented, there is a long tail effect, it is difficult to use a technology to meet all applications, 3GPP developed NB-IoT and eMTC slightly different in performance, the difference is for the Internet of Things The application is tailored.
Recently, China Mobile officially established the Internet of Things Alliance OneNET, and MediaTek and China Mobile launched the NB-IoT universal module based on the MT2625 chip. This module integrates China Mobile's "eSIM card", a so-called e-SIM card, which is a software and hardware solution to replace the physical SIM card. As part of the smart phone function module, e-SIM no longer has a physical card. The OneNET platform has Helps reduce the NB-IoT development threshold and help developers or startups easily create IoT devices and related applications.
Take China Mobile's shared bicycle smart lock as an example. A battery can be used for more than 6 years. The user can know the position of the bicycle in the city at any time. In the locked state, the vehicle moves, dumps, and the lock is attacked by an external force. Immediately report the abnormality and location to ensure the safety of the vehicle. The unlocking time is only 2-3 seconds. The user can use the App button to unlock, scan the code to unlock or swipe the card to unlock.
The mainland official is pushing the Internet of Things. In June, the Ministry of Industry and Information Technology issued the "Notice on Comprehensively Advancing the Construction and Development of Mobile Internet of Things (NB-IoT)", requesting to speed up the landing of NB-IoT (NarrowBand IoT, Narrowband Internet of Things). At the end of this year, 400,000 base stations will be built, and the three major telecom operators will move.
According to the plan, the Internet of Things is applied in the field of public services, including the promotion of smart city construction. Taking the fields of smart metering of water, electricity and gas meters, public parking management, environmental protection monitoring, etc. as the entry point, combined with the construction of smart cities, the ability to help public services is continuously improved. Applications in personal life include applications in smart homes, wearables, child and elderly care, pet tracking and consumer electronics.
In 2014, Huawei first proposed the narrowband technology NB M2M, and then merged with Qualcomm, Ericsson and other companies to evolve into NB-IoT. In June 2016, the NB-IoT core protocol standard was adopted in 3GPP. NB-IoT is a standard technology introduced by 3GPP. After many discussions, it has become a new narrow-band IoT technology standard that is widely accepted around the world. It is a comprehensive product of technological evolution and market competition.
Huawei is the largest NB-IOT chip manufacturer in China, covering chips and solutions in wireless networks, fixed networks, digital media, etc., and successfully applied in more than 100 countries and regions around the world. In the digital media field, SoC network monitoring has been launched. Chips and solutions, videophone chips and solutions, DVB chips and solutions and IPTV chips and solutions. At the same time, the products cover a variety of standard and packaged communication module products, vehicle networking communication terminal products, industry special terminals and IoT overall solutions, and have been recognized by various industries at home and abroad with continuous innovation and excellent quality.
