The NB-IoT standard has been frozen in June and there is no doubt that this year will be the key year for the NB-IoT industry. Whether it is chip suppliers, operators or even national governments, all parties in the eco-chain are actively promoting the commercial operation of NB-IoT. Recently, Huawei revealed in public that its NB-IoT commercial chip will take the lead in mass production in Q4 this year. The first national-level Internet of Things industry base will also land in Fuzhou, which indicates that China's NB-IoT industry will enter into substantive Force stage.
Pig on the tuyere? Huawei wants to be a "windist"
"As long as you stand in the wind, the pigs can fly." Lei Jun was praised as a famous saying by countless intelligent hardware startups. Everyone flocked to the wind and put POSE and other winds to come. After three years, the wind did not wait until only one sentence. The death sentence of "collectively stepping into the air". Why is this happening? Is the Internet of Things really a big pit?
In an industry event, the reporter of the smart product circle met Lu Jiang, the marketing director of Huawei's wireless product line terminal business management department, and he made a simple exchange on the development of NB-IoT industry. He believes that the development of the Internet of Things is mainly due to the following reasons: First, the standards are not unified: the interconnection between devices is the basis for the development of the Internet of Things, but at present there are many standards in the industry, each of which is based on the same standard. The WiFi modules that are made can't communicate directly with each other, plus the IoT application connection requirements and the scenes are different. These all bring great difficulties to the practical application.
Secondly, there are many mobile phone accessory models: smart hardware companies are often difficult to jump out of the thinking limitations of the mobile Internet era, and make a fuss about the human-computer interaction mobile phone ecology. In fact, in the field of Internet of Things, there are many application requirements for sensing, metering, monitoring, etc., which are based on a new independent ecosystem based on the communication of things and things.
Third, the Internet of Things is mixed with consumer electronics: In the past few years, the Internet of Things has a very distinctive feature that is surrounded by hot circles and cold, and various kinds of intelligent hardware products are crowd-funded and open-line experience stores. B2C has become a B2VC that has changed its taste, and the actual sales volume has been paid. On the other hand, domestic appliance manufacturers are actively carrying out intelligent upgrades. Currently, the Wi-Fi activation rate of white goods is 40%, but what is the activation rate still used after half a year of sales? Less than 5%!
"This is because consumers do not feel the tangible benefits brought by the Internet of Things." Lu Jiang believes that the value of the Internet of Things at this stage is actually in B2B2C, taking smart home appliances as an example: through remote monitoring of the operating status of home appliances, Home appliance manufacturers can conduct product lifecycle data management, obtain consumer habits, use preferences, predict maintenance needs in advance, and actively remind consumers to replace consumables... and all of this has only one purpose - to improve service quality and enhance brand Word-of-mouth communication and continuous repurchase rate.
"The Internet of Things is not equal to intelligent hardware, and it is not equal to consumer electronics. Network construction that meets the special needs of physical and physical communication is the first step," he said.

Five technical advantages to seize the main position of IoT
In the IoT era, tens of billions of objects will be connected to the network. In the past, communication networks were used to serve people. For example, short-range wireless access technology and mobile cellular network technology value high-speed bandwidth, allow frequent charging, and communication between objects and objects in the Internet of Things. Otherwise, business characteristics, connection requirements, and scene differentiation are large, which has led to the rise of LPWA (Low-Power Wide Area Network) to build a network with low bandwidth, low power consumption and strong coverage to cope with the Internet of Things era. As a leader in long-distance wireless communication technology, NB-IoT has the following significant advantages:
Advantage 1: Big connection. In the case of the same base station, NB-IoT can provide 50-100 times the number of accesses than existing wireless technologies. For example, limited by bandwidth, operators only open 8-16 access ports for each router in the home, and a family often has multiple mobile phones, laptops, and tablets. In the future, it is necessary to realize the whole house intelligence. The need for networking across hundreds of sensing devices has become a daunting challenge. And NB-IoT is enough to easily meet the needs of a large number of devices in the future smart home networking.
Advantage 2: Wide coverage. NB-IoT boosts 20dB gain over LTE, which not only meets the wide coverage requirements of rural areas, but also applies to applications such as plant areas, underground garages, and manhole covers that require deep coverage. Taking the manhole cover monitoring as an example, in the past, the GPRS method required an antenna to be extended, and the vehicle was extremely vulnerable to damage. The NB-IoT can solve this problem as long as it is properly deployed.
Advantage three: ultra low power consumption. Low-power features are an important indicator for IoT applications, especially for devices and occasions where batteries cannot be replaced frequently, such as sensors that are placed in remote areas of the Alpine Wilderness. The battery life of several years is the most essential requirement. NB-IoT focuses on small data volume and small rate applications, so the power consumption of NB-IoT devices can be very small, and the battery life can be greatly improved from the past few months to several years.
Advantage four: low cost. Compared with LoRa, NB-IoT does not need to re-build the network, and the radio and antenna are basically multiplexed. Taking China Mobile as an example, there is a relatively wide frequency band in 900MHZ. Only a part of the 2G frequency band needs to be cleared, and the simultaneous deployment of LTE and NB-IoT can be directly performed. Low speed, low power consumption and low bandwidth also bring low cost advantages to NB-IoT chips and modules.
Advantage 5: stable and reliable. NB-IoT is deployed directly on the GSM/LTE network, but does not occupy the voice and data bandwidth of the existing network, ensuring that traditional services and future IoT services can be performed stably and reliably at the same time. Taking the smart meter reading application as an example, the recovery rate of PLC meter reading data is about 60%, and NB-IoT can be increased to 99%. In addition, compared to the Wi-Fi mode, NB-IoT has a higher data security factor and is more favored by data-sensitive enterprise customers.
Restructuring the business model early in the market is the key
Supporting massive connections, deep coverage, and low power consumption, these inherent advantages make NB-IoT ideal for smart meter reading, intelligent parking, vehicle tracking, logistics monitoring, etc. that require sensing, metering, monitoring, and more. Intelligent manufacturing, intelligent agriculture, forestry, animal husbandry and fishery, as well as smart wear, smart families, smart communities and other fields. The widely used 2G/3G/4G and other wireless technologies are currently unable to meet these challenges.
