Nb-iot is what _nb-iot advantage _nb-iot application
In August 2015, 3GPP RAN began research on a new air interface technology for narrowband wireless access called Clean Slate CIoT, which covers NB-CIoT. NB-CIoT was jointly proposed by Huawei, Qualcomm and Neul. NB-LTE was proposed by Ericsson, Nokia and other manufacturers. NB-CIoT proposes a new air interface technology, which is relatively large in the existing LTE network, but NB-CIoT is the only 6 proposed Clean Slate technology, the only one that meets the requirements of the TSG GERAN #67 conference. Cellular IoT technology with large targets (increasing indoor coverage performance, supporting large-scale device connections, reducing device complexity, reducing power consumption and delay), especially NB-CIoT communication module costs lower than GSM modules and NB- LTE module. It is predicted that in 2016, 6.4 billion IoT devices will be connected to the network every day, and 5.5 million devices will be connected to the network. One of the foundations of the “Internet of Everything†is the transmission of data, and the data transmission capabilities of different IoT services. Real-time has different requirements. According to different transmission rates, IoT services can be distinguished between high, medium and low speed: high-rate services: mainly use 3G and 4G technologies, such as vehicle-mounted IoT devices and surveillance cameras, and the corresponding service features require real-time data transmission; Medium-rate services: mainly use GPRS technology, such as lockers in residential quarters or supermarkets, which are used frequently but not in real-time. The requirements for network transmission speed are far less than high-speed services; Low-rate services: The industry has classified the low-rate service market into the LPWAN (Low Power Wide Area Network) market, which is a low-power WAN. At present, there is no corresponding cellular technology, and in most cases, it is supported by GPRS technology, which brings about a problem of high cost and low penetration of low-rate services. That is to say, the current low-rate business market is in urgent need of development, and the low-speed business market is actually the largest market, such as fire extinguishers in buildings, various monitors used in scientific research, and the frequency of such devices in life is very low. But the total number of collections is considerable, and the collection of these data is used for various purposes, such as improving the configuration of urban equipment. NB-IoT is a new narrowband cellular communication LPWAN (Low Power Wide Area Network) technology that can help us solve this problem. Mobile communication is moving from the connection between people and people to the connection between people and things and things, and the Internet of Everything is an inevitable trend. However, current 4G networks are not capable of connecting objects to objects. In fact, compared with short-range communication technologies such as Bluetooth and ZigBee, mobile cellular networks have features such as wide coverage, mobility, and large number of connections, which can bring more rich application scenarios and should become the main connection technology of the Internet of Things. As an evolution of LTE technology, in addition to peak rate of up to 1Gbps, 4.5G also means more connections based on cellular IoT, support for massive M2M connections and lower latency, which will boost HD video, VoLTE and Internet of Things. Such applications are rapidly spreading. The cellular Internet of Things is opening up a vast market that has never been seen before. For telecom operators, IoT applications such as car networking, smart healthcare, and smart home will generate massive connections, far exceeding the communication needs between people. NB-IoT has four characteristics: First, wide coverage will provide improved indoor coverage. In the same frequency band, NB-IoT gains 20dB more than the existing network, and the coverage area is expanded by 100 times. Second, it has a large number of connections. Capability, NB-IoT can support 100,000 connections in one sector, supporting low latency sensitivity, ultra-low device cost, low device power consumption and optimized network architecture; third is lower power consumption, NB-IoT terminal module Standby time can be as long as 10 years; fourth is lower module cost, the company expects a single connected module to be no more than $5. NB-IoT focuses on the low-power wide coverage (LPWA) Internet of Things (IoT) market and is an emerging technology that can be used globally. It has the characteristics of wide coverage, many connections, low speed, low cost, low power consumption and excellent architecture. The NB-IoT uses the license band and can be deployed in the inband, guard band or independent carrier mode to coexist with the existing network. Because of its low power consumption, wide coverage, low cost, and large capacity, NB-IoT can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, intelligent parking, and smart agriculture. The first version of the 3GPP standard is expected to be released in June this year, when a number of test networks and small-scale commercial networks will emerge. With the advent of smart cities and the era of big data, wireless communication will achieve universal connectivity. Many companies expect that the number of global IoT connections in the future will be a billion-dollar era. A large number of physical and physical connections have emerged. However, most of these connections are carried by short-range communication technologies such as Bluetooth and Wi-Fi, but non-operator mobile networks. In order to meet the needs of different IoT services, according to the characteristics of IoT services and the characteristics of mobile communication networks, 3GPP has carried out technical research to enhance the functions of mobile communication networks in accordance with the application scenarios of narrowband services to meet the needs of the booming IoT business. We are entering the era of Internet of Everything (IoT), which is a huge opportunity for the entire mobile communications industry. Both the operators and the equipment giants are demonstrating their IoT solutions and applications in different vertical industries. Of course, the basis for achieving this is to have a ubiquitous network connection. The operator's network is the most widely covered network in the world, so it has unique advantages in access capabilities. However, a reality that cannot be ignored is that the physical and physical connections that are actually carried on the mobile network account for only 10% of the total number of connections, and most of the objects and objects are connected by Bluetooth, Wi-Fi and other technologies. To this end, the industry chain has been studying the use of narrowband LTE technology to carry IoT connections from a few years ago. After several renaming and technology evolution, in September 2015, 3GPP officially named this technology NB-IoT. At MWC2016, NB-IoT debuted, attracting attention, operators and equipment vendors have their platforms and endorsements. Technically speaking, NB-IoT has four technical advantages. The first is wide coverage. Compared with traditional GSM, one base station can provide 10 times area coverage. Secondly, massive connection, 200KHz bandwidth can provide 100,000 connections. The third is low power consumption. It can work for ten years with AA battery. No need to charge; the fourth is low cost, the module cost is less than 5 US dollars. It is understood that NB-IoT can be widely used in a variety of vertical industries, such as remote meter reading, asset tracking, intelligent parking, smart agriculture and so on. With the release of the first version of the 3GPP standard in June, a number of test networks and small-scale commercial networks will emerge. NB-IoT will stand out in multiple low-power WAN technologies. In addition, more and more industries are already using IoT technology to increase efficiency, increase customer satisfaction and reduce operating costs. For example, Bosch, a manufacturer of automotive components, household appliances and safety systems, has connected many product lines and directly benefited from the rise of mobile internet technology, especially in the field of car networking. In the medical field, Philips has developed several e-health applications, including a patch for patients with chronic conditions. The patch uses sensors to collect patient health data in real time and transmit it to the cloud platform, allowing healthcare professionals to monitor data and take timely medical interventions. Alberto Prado, director of the Philips Digital Accelerator Program, points out that interoperability of devices and systems is key to the rise of the digital healthcare industry. As the collaborative care model becomes more prevalent, future medical care will inevitably integrate all resources and take active prevention as the main factor. In order to meet the huge opportunities in the field of Internet of Things, the entire industry not only needs to promote technological innovation, but also needs to promote business model innovation and cross-industry collaboration. The Internet of Things market will be more fragmented than the mobile market due to the variety of use cases, applications and business models. 1. Application of NB-IoT in fire protection system (smoke detector) There are often fires in the news reports, and every fire is accompanied by a broken family. Every scene is shocking. We must improve fire protection awareness and use fire fighting equipment in a reasonable manner to minimize losses and injuries. The smoke sensor is the sentinel of the fire protection system. It can detect smoke in real time. The sensor detects the smoke concentration exceeding the standard, sends the information to the background server, and starts the alarm bell, broadcast speaker and other related equipment. The server will automatically push the information to the relevant personnel and departments to realize Fire safety is intelligent. In practical applications, according to fire protection requirements, the installation of smoke detectors is densely distributed, which is inconvenient to route and costly. The use of NB-IoT wireless smoke detector can avoid the problem of difficult wiring and greatly save the installation cost; NB-IoT has a large number of connections, and the number of smoke detectors can reach more than 100,000, which can meet the massive amount. The smoke sensor is connected at the same time; NB-IoT has ultra-low power consumption and can work for ten years in standby mode, which greatly reduces the maintenance cost after installation; NB-IoT has super signal coverage and can cover indoors. And the basement; NB-IoT ultra-low cost, the chip is estimated to be as low as $1. 2. NB-IoT is applied to asset location tracking system With the in-depth development of information technology and various intelligent terminal devices, the demand for personnel and asset positioning will continue to heat up. The application of location services also presents fragmentation features such as asset inventory in smart campuses, medical waste tracking, and pet positioning. . . Today, most of the trackers on the market are based on GSM, and power consumption is a big problem. Large chip area, high cost, relatively low coverage, etc., this technology happens to be contrary to the needs of the location tracker. The GSM technology is quite backward, resulting in poor product experience of the location tracker. In some countries, GSM has already retired or is facing network retreat, resulting in a shortage of such products and technologies. The birth of NB-IoT technology and its birth with low power consumption and deep coverage properties make up for the shortcomings of traditional communication technology. This can be used to locate assets tracking whether it is in an indoor or outdoor area. NB-IoT technology, its low power consumption, wide coverage, low cost, small size and other characteristics make it an indispensable communication method in the field of asset tracking. 3, NB-IoT application in smart home (smart lock) With the popularity of the smart home industry in recent years, the frequency of smart locks appearing in life is getting higher and higher. At present, smart locks use non-mechanical keys as the technology for user identification ID. Mainstream technologies include proximity cards, fingerprint recognition, and passwords. Identification, facial recognition, etc., greatly improve the security of the access control, but the premise of the above security is that in the power-on state, if the smart lock is in the power-off state, it is ineffective. 1. In order to improve security, you need 2, smart lock has a built-in battery 3. Collect basic data 4, transfer data to the server 5, collecting abnormal data automatically alerts the user Because the smart lock is not easy to disassemble after installation, the smart lock battery is required to have a long service life; if the door is in a closed corridor, a stronger signal coverage is needed to ensure real-time transmission of network data; the number of smart home terminals must be sufficient. The number of connections; the most important thing is to ensure that the equipment cost is controlled within an acceptable range after adding the above functions. Application of NB-IoT technology to smart home systems 1, NB-IoT has low power consumption characteristics, only two AA batteries can be used for ten years, greatly reducing post-maintenance costs. 2, super strong signal coverage, can cover indoor and basement, to ensure signal stability. 3, a large number of connections, to meet the simultaneous connection of multiple terminals in the smart home. 4, low cost, the price of a single NB-IoT chip is less than 1 US dollar.
