With the rapid development of the Internet of Things market, the demand for long-distance large-scale IoT deployment is increasing, but GPRS, 3G, and 4G technologies are difficult to support large-scale terminal numbers, so they have low power consumption, low cost, high coverage, and strong connection advantages. The NB-IoT technology has received wide attention.
NB-IoT refers to the Narrow Band - Internet of Things technology. By reading this issue of Technology Weekly, you can not only understand what NB-IoT technology is, but also understand the key nodes of NB-IoT technology development, as well as the solution and application direction of the technology, and also understand the Internet of Things era and NB- IoT technology competes for market-related communication technologies.

| What is NB-IoT?
The development of NB-IoT is a combination of NB Clot technology jointly proposed by Huawei, Vodafone and Qualcomm and NB LTE technology of Ericsson.
The NB-IoT technology protocol was approved by the 3GPP Radio Access Network (RAN) Technical Specification Group meeting on June 16, 2016. It took less than eight months from project initiation to co-freezing, making it one of the fastest established 3GPP standards in history. After the performance standard is finalized in September and the conformance test is completed in December, NB-IoT can enter the commercial phase.

There are many wireless communication technologies in the Internet of Things, which are mainly divided into two categories: one is Zigbee, WiFi, Bluetooth, Z-wave and other short-range communication technologies; the other is LPWAN (low-power Wide-Area Network). ), that is, wide area network communication technology. LPWA can be divided into two categories: LoRa, SigFox, etc., which work on unlicensed spectrum; and 2/3/4G cellular communication technologies, such as EC-GSM, which are supported by 3GPP and operate under licensed spectrum. LTE Cat-m, NB-IoT, etc.
| NB-IoT chip, module
After the announcement of the standard, Huawei Hisilicon, as the leader, will launch the NB-IoT commercial chip at the end of September this year. This will be the industry's first commercially available NB-IoT chip, and its chip price will be short-distance communication chip price. near. The realization of the Internet of Everything has added a big weapon, and the popularity of the Internet of Things has accelerated.
At present, operators such as ATT and Verizon in the United States attach more importance to CAT-M than NB-IOT, and Chinese operators are also piloting the technology. It is understood that ZTE Microelectronics has completed the pre-research of the agreement and can cooperate with the agreement of the Chinese operator construction plan, sample test and final commercial.

Since NB-IoT is not yet commercially available, there are still few chips and modules, but many manufacturers' NB-IoT chips will be released soon.
Dr. Zhou Yujun, Senior Deputy General Manager and Chief Technology Officer (CTO) of MediaTek, revealed in an interview with MWC2016 (World Mobile Congress - Shanghai) that NB-IOT-based chips will be launched next year.
Domestic manufacturers, Datang Telecom has launched FDD/NB-IoT products, which have been deployed in the Internet of Things market. As a supplier of communication chips, Ziguang has a certain card position advantage in the field of NB-IoT; Beijing Junzheng One of the core suppliers of IoT chip modules.
| NB-IoT application areas and cases
The core of NB-IoT is for low-end IoT terminals (low-power consumption), which is more suitable for wide-distribution applications in smart homes, smart cities, smart production, etc. represented by smart meter reading, smart parking, and intelligent tracking. Will shine a lot. Some experts believe that "NB-IoT technology allows us to see the hope that products such as smart bracelet smart watches can be used independently of mobile phones, independent of mobile phones, and may continue to be used for more than 30 days; and in addition to The need for more application scenarios such as positioning and tracking on people is also very clear.
Look at those applications of NB-IoT from three major industries
NB-IoT will detonate the smart wearable market
According to McKinsey's latest research results, IoT has broad application prospects. It is expected that the Internet of Things will reach 11.1 trillion US dollars in 2025, of which NB-IoT will reach 42 billion US dollars and reach 420 million connections. Shanghai Unicom and Huawei have jointly created NB-IoT's success stories in the fields of intelligent parking and smart meter reading, which have received industry attention.

| What are the supporters and competitors of NB-IoT technology?
The Internet, the terminal, the network, the chip, the operating system, the platform and other parties have always had different paths, which has made the Internet of Things "fragmented" serious. With the giants such as Intel, Qualcomm, Ericsson and Nokia joined the NB-IoT camp. The giant alliance may become an opportunity to end the fragmentation and unify the Internet of Things.

New Arrival or New Style Lio Nano Disposable ecig have a completely enclosed design, reducing the need for charging and replacing cartridges. The no-charge design also reduces the occurrence of faults. It is understood that with rechargeable e-cigarettes, each cartridge needs to be charged at least once and the battery efficiency is extremely low, while the design of disposable ecig can solve this problem very well.
