The nb-iot (narrowband cellular Internet of Things) standard was adopted by the international organization 3GPP. The industry believes that 2016 will undoubtedly be included in the history of communication as a commercial first year of nb-iot. Just as the mobile Internet is eager for the 4G era in the past decade, today's Internet of Things is also eager for a strong cellular IoT infrastructure network, and nb-iot is undoubtedly the best choice for this basic network.
In addition, the Chinese government has repeatedly confirmed that it will realize 5G commercialization by 2020. Nowadays, various technologies for 5G have rapidly warmed up, and many technical solutions have gradually landed. At the M2M conference in London in April this year, Huawei demonstrated the nb-iot (narrowband cellular Internet of Things) strategy and innovations in IoT applications and smart cities, and introduced the partnership with partners to build the nb-iot ecosystem. Work, including the establishment of the Vodafone nb-iot open laboratory with Vodafone in Newbury, UK, aims to leverage the potential of nb-iot to create social and economic benefits. Nb-iot (narrow-band cellular Internet of Things) is undoubtedly a hot spot in the Internet of Things in the 5G era.
Nb-iot has the most realistic foundation
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 joining the nb-iot camp, The giant alliance may become an opportunity to end the fragmentation and unify the Internet of Things.
Nb-iot is built on a cellular network and consumes only about 180KHz. It can be deployed directly on GSM networks, UMTS networks or LTE networks to reduce deployment costs and achieve smooth upgrades.
Nb-iot technology is an LPWA (Low Power Wide Area Network) solution defined by the 3GPP standard with the following advantages:
1. Massive connection: Up to 100,000 connections per cell; NB-IoT has 50-100 times higher uplink capacity than 2G/3G/4G, which means that in the case of the same base station, nb-iot can be compared Existing wireless technologies provide 50 to 100 times the number of accesses.
2, ultra low power consumption: battery life of up to ten years;
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. In the absence of breakthroughs in battery technology, battery power can only be extended by reducing device power consumption. The energy consumed by a communication device is often related to the amount or rate of data, that is, the size of the data packet sent per unit time determines the amount of power consumption. The amount of data is small, and the modem and amplifier of the device can be adjusted to a very small level. Nb-iot focuses on small data volume and small rate applications, so the power consumption of nb-iot devices can be very small, which can guarantee the battery life of more than 5 years.
3, deep coverage: can achieve 20db higher coverage than GSM;
Nb-iot boosts 20dB gain over LTE, which is equivalent to a 100x increase in transmit power, which is 100 times more coverage, even in areas such as underground garages, basements, and underground pipes that are difficult to reach.
4. Security: Inherit 4G network security capabilities, support two-way authentication and strict air interface encryption to ensure the security of user data;
5, stable and reliable: can provide carrier-class reliability access, effectively support IoT applications and smart city solutions.
NB-IoT can be directly deployed on GSM network, UMTS network or LTE network, and can be reused with existing network base stations to reduce deployment cost and achieve smooth upgrade. However, using a separate 180KHz band does not occupy the voice and data bandwidth of the existing network. To ensure that traditional business and future IoT business can be carried out stably and reliably at the same time. Taking the smart meter reading application as an example, compared with the use of wired PLC meter reading data recovery success rate of about 60%, nb-iot can ensure the data recovery rate is 99%, and the reliability is greatly improved.
Editor's Note: The Internet, 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 nb- In the iot camp, the giant alliance may become an opportunity to end the fragmentation and unify the Internet of Things.
6, low cost
Low speed, low power and low bandwidth bring low cost advantages. Low rate does not require large buffers, so it can be cached small, DSP configuration is low; low power consumption means low RF design requirements, small PA can be achieved; because of low bandwidth, do not need complex equalization algorithms. These factors make the nb-iot chip can be made small. The cost of the chip is often related to the chip size. The smaller the size, the lower the cost, and the lower the cost of the module.
Since nb-iot has the characteristics of immediate deployment based on real-world networks, operators who need it now can act quickly. As the insiders have said, the surge of 5G is like a love coming in advance and vigorously. In order to make this love more sweet, the best solution is to base more on reality. Therefore, this year, nb-iot has won the top spot in the Internet of Things.
Nb-iot ecology is maturing
As the profits of traditional telecom services become thinner and thinner, the entire telecommunications industry is looking for new profit growth points. The market for people and people is getting closer to saturation, and the huge market for people, things, things and things is just Rise.
According to GSMA predictions, nb-iot will reach 3 billion connections in 2020; Machina also predicts that nb-iot will cover 25% of IoT connections in the future. Gartner predicts that 6.4 billion IoT devices will be put into use in 2016, up 30% year-on-year and will reach 20.8 billion in 2020. At the same time, spending on IoT services in 2016 will grow by 22% to $235 billion.
With the advent of the era of Internet of Everything, networking is becoming a necessity for all industries and equipment. At the same time, the popularity of cloud computing and big data has made devices more inclined to connect to the Internet, which has brought nb-iot many development opportunities, such as car networking, telemedicine, logistics and so on. Therefore, the Internet of Things, which is the closest to the operator's business and has a huge market prospect, is undoubtedly the best entry point for operators.
2016 will be a very crucial year for the development of the nb-iot industry. For nb-iot to be successful, it must be supported by various industry platforms in the ecosystem.
From the perspective of solutions/chips, Huawei, Ericsson and Qualcomm are actively developing and producing such chips. Many chip manufacturers and module manufacturers also plan to support nb-iot this year.
From the operators' response and investment in nb-iot, the nb-iot standard has received responses from many mainstream operators, such as China Mobile, China Unicom, China Telecom, Vodafone, Deutsche Telekom, Emirates Telecom, Telecom Italia, AT&T and other global top operations. Businesses have released their respective development strategies around nb-iot. It is estimated that half of the world's 50 mainstream operators will support nb-iot in 2016.
In the domestic market, the three major telecom operators have taken active actions. At MWCS 2016 in June, China Mobile and Ericsson and Intel completed the world's first business demonstration based on the latest cellular IoT technology - nb-iot: China Telecom Chairman Yang Jie said recently that China Telecom's deployment in the first half of 2017 is based on The 800MHz nb-iot network will achieve full network coverage; China Unicom plans to launch 900MHz, 1800MHz nb-iot field-scale networking test and service demonstration in more than 5 cities this year, and plans to promote nb- in key cities around the end of this year. Iot commercial deployment.
In addition to industry applications, consumer industries such as white goods manufacturers have begun to use nb-iot chips for product development. The nb-iot ecology is taking shape in an unstoppable situation, bringing tremendous opportunities to all walks of life.
There are still difficulties to overcome
The telecommunications industry generally believes that nb-iot has its own advantages over traditional IoT technology. However, it still has its own limitations, and the cost price and power consumption may become obstacles to the development of nb-iot. In terms of cost, the cost of nb-iot modules is expected to fall to less than $5 in the future, but the current price of chips supporting Bluetooth, ZigBee and other standards is only about $2, and only one of the standard chips is less than $1. The huge price gap will undoubtedly cause companies to deploy nb-iot concerns.
Vodafone's Ibbetson believes: "If the industry chain can't reduce the cost of a single module to less than two or three dollars and achieve large-scale application, the nb-iot market will not be able to do it. We need to take the Internet of Things at a very low cost from a global perspective. The module is embedded in the device."
Huawei's Hu Hou also believes that in order to stimulate the large-scale development of nb-iot, the cost of the communication module must be less than $5. If the cost falls below $1, it will lead to explosive growth.
At the same time, the Internet of Things application is still in the stage of trial and demonstration exploration, with less scale application and insufficient innovation vitality. At this stage, operators, Huawei, Ericsson and other equipment manufacturers, Qualcomm and other chip suppliers represented the supply side is more enthusiastic, while the demand side of the application body, such as water and electricity public service providers have not yet heated up, based on the development of the Internet of Things Trends and Thai are laying out future smart life scenes.
