NB-IoT, or Narrow Band-Internet of Things, is an emerging technology of the Internet of Things, which supports the efficient connection of devices with long standby time and high network connection requirements. Narrow Band-Internet of Things has the characteristics of low cost, low power consumption, high coverage, etc. It is positioned at the operator level and satisfies the low-speed Internet of Things market, and has broad market prospects.
1. NB-IoT application
In order to welcome the innovation of the Internet of Things business model and cross-industry collaboration, the Internet of Things market will become more fragmented. With the huge opportunities in the core areas of standards, the entire industry not only needs to promote technological innovation, but also needs to recommend freezing. NB-IoT(Narrow Band-Internet of Things) is currently the biggest hot spot in the communications industry and is widely used in a variety of vertical industries, such as remote meter reading, asset tracking, smart parking, and smart agriculture. With the emergence of a batch of test networks and small-scale commercial networks, NB-IoT application will stand out among multiple low-power wide area network technologies.
2. Optimistic about the NB-IoT market at home and abroad
Internationally: In January 2017, Vodafone announced the official commercial NB-IoT network in Spain. Currently, 21 operators worldwide have committed to deploying NB-IoT networks. By the end of 2017, 25 NB-IoT networks will be officially deployed globally.
Domestically: In 2014, Huawei acquired Neul, a leading provider of cellular IoT chips and solutions in the UK. After the announcement of the NB-IoT standard, Neul quickly launched the industry's first official commercial NB-IoT chip. The three major operators, China Mobile, China Telecom, and China Unicom, have already joined the battle. As early as June 2016, China Unicom deployed 10 NB-IoT(Narrow Band-Internet of Things) outdoor sites in Shanghai Disneyland to cover the entire park. In October of the same year, China Unicom opened the country's first standardized NB-IoT commercial network in Guangzhou. In November last year, China Telecom established an experimental network in Nanjing. This year, the country's first NB-IoT network was officially commercialized in Yingtan. At the same time, China Telecom also released the "NB-IoT Enterprise Standard V1.0". China Mobile also used NB-IoT technology in Nanjing to build a smart street light project.
3. Typical application of NB-IoT(Narrow Band-Internet of Things)
Autonomous abnormality report business types: such as smoke alarm detectors, equipment abnormalities, etc., uplink very small amount of data (ten bytes in the order of magnitude), and the cycle is mostly in years and months.
Autonomous periodic report business types: such as remote meter reading and environmental monitoring of public utilities, with a small amount of uplink data (in the order of hundreds of bytes), and the cycle is mostly in days and hours.
Remote control command service type: such as remotely turning on/off the device, triggering the device to send an uplink report, a very small amount of downlink data (on the order of ten bytes), and the cycle is mostly in days and hours.
Software remote update service type: such as software patch/update, a large amount of upstream and downstream data (kilobytes) is required, and the cycle is mostly in days and hours.
