Practical application demonstration of NB-IoT solutions
Here are a few NB-IoT related applications to give you a deeper understanding of what they mean.
(1) Huawei/China Unicom's NB-IoT smart parking solution: The smart parking system launched based on Huawei's NB-IoT module will be able to realize functions such as reservation and sublease of parking spaces, and the low power consumption and high penetration ability make this solution more reliable. At present, the parking system has been put into trial use at Shanghai Disneyland.
(2) ZTE/China Mobile's intelligent manhole cover: This solution can realize timely warning when the manhole cover is opened or displaced by comprehensively supervising the status of the manhole cover. NB-IoT technology has the characteristics of low cost, wide coverage, low power, and large connection, which can effectively improve the coverage area of the intelligent manhole cover monitoring system, eliminate coverage dead spots, and reduce construction and maintenance costs.
(3) China Mobile/Ericsson/Intel environmental detection application: Intel's latest NB-IoT chip (XMM7115) is used, which can monitor the PM value, temperature, humidity, light brightness, etc. of the environment in real time.
NB-IoT Development and Challenges
First of all, let's talk about the advantages and value of NB-IoT solutions: 1. Wide and deep coverage: 20dB+ better than GPRS coverage; 2. Low power consumption: based on AA battery, the service life can be more than 10 years; 3. Low cost; 4. Large connection: 50k+ user capacity/200kHz cell.
With the above advantages, NB-IoT technology has attracted the favor of mainstream operators and equipment manufacturers around the world, and with the freezing of standards, NB-IoT will usher in commercial use in September this year. According to relevant reports, China Unicom plans to promote the commercial deployment of NB-IoT in key cities by the end of this year and early next year. In addition, the Ministry of Industry and Information Technology also held a narrowband IoT work promotion meeting in April, intending to build a large-scale field experiment based on the NB-IoT standard by the end of the year. According to relevant market research, by the end of this year, 50 mainstream operators around the world will support NB-IoT, which will cover 1/4 of IoT connections in the future, and M2M devices will reach 7 billion connections by 2020.
NB-IoT, as a new standard technology, is under competitive pressure from Sigfox and LoRa technologies (the industrial chain is relatively mature and the commercial application is earlier). However, Sigfox and LoRa are unauthorized frequency bands and are not favored by operators and equipment manufacturers. Although the NB-IoT market has broad prospects, there is also a price war behind the fire. NB-IoT costs are extremely low, and the cost will drop to $1 for large-scale applications, and currently it is still at $5 for a single connection module. The price of chips for Bluetooth, Thread, and ZigBee standards is about $2, and the price of chips that support only one of the standards is less than $1.
