For the low-power wide area network, from the vertical perspective, a complete industrial chain has been formed from the "bottom chip-module-terminal-operator-application".


Among them, the chip is at the core of the entire industry chain of NB-IoT, and now almost all mainstream chip and module manufacturers have a clear NB-IoT support plan.


Huawei's acquisition of the company's Neul chip is implemented earlier, and there are already test samples; Qualcomm's chips are expected to be released in the fourth quarter of 2016, and Qualcomm’s chips are NB-IoT and eMTC dual-mode chips; Intel’s chips are expected to The first batch of chips will be provided in the quarter, but mainly based on testing, commercial chips will be released early next year; MTK's chips are also under research and development, and will be released in the first half of next year; ZTE Microelectronics and Datang chips are also in development. among.


Here we select Huawei and Qualcomm to talk specifically. Why should you choose these two? Because of the evolution of the NB-IoT standard, Huawei and Qualcomm played a very important role. The current NB-IoT evolved from the solution NB-CIoT produced by Huawei and Qualcomm. (Details everyone can own Baidu)


1, Huawei

As Huawei, an active participant in NB-IoT, NB-IoT is a big strategy and it is said that all Huawei departments are actively involved.


In fact, as early as 2014, Huawei spent US$25 million to acquire the UK’s leading provider of cellular the Internet of Things chips and solutions, Neul, and also planned to build a global-level Internet of Things centered on Neul.


As expected, after the announcement of the standard, Neul will soon launch NB-IoT commercial chips at the end of this month. This will be the industry's first commercial NB-IoT chip, and its price will be closer to the price of short-range communications chips.


It is reported that Huawei's NB-IoT chip integrates BB and AP, Flash, and battery management within the size of a coin, and reserves sensor integration capabilities. The AP contains three ARM-M0 cores. Each M0 core is responsible for the application, security, and communication functions. This facilitates functional management while reducing costs and power consumption. The subsequent chips will also integrate Soft SIM, further reducing cost.
