The rapid development of the Internet of things has made a higher demand for wireless communication technology, and the LPWA (Low-power wide-area network, low Power WAN), designed for low bandwidth, low power, long distance, and a large number of connected IoT applications, is also rapidly emerging.

In order to rob Lpwa business opportunities, the relevant manufacturers have formed alliances to launch different agreements, NB-IoT and Lora is a typical representative. Huawei and Vodafone jointly proposed NB-IoT as a 2/3/4g cellular communication technology that works in 3GPP supported by the licensed spectrum. The Lora developed by Semtech is a communication technology based on Sub-ghz that works in an unlicensed spectrum. Together with Lpwa, why does Vodafone innovation and architecture director Matt Beal suggest that NB-IoT will crush Lora technology so sharply?

Is NB-IoT more technically superior than Lora?
In August 2015, 3GPP ran began research on narrowband wireless access to new air interface technology, called Clean slate Ciot, which covers Nb-ciot. Nb-ciot is jointly proposed by Huawei, Qualcomm and Neul, Nb-lte by Ericsson, Nokia and other manufacturers.
Nb-ciot proposed a new air interface technology, relatively in the existing LTE network changes larger, but Nb-ciot is proposed 6 large cleanslate technology, the only one to meet in the TSG Geran #67会议中提出的5大目标 (improve indoor coverage performance, support large-scale device connectivity , reduce the complexity of equipment, reduce power consumption and delay), the cellular Internet of things technology, especially the Nb-ciot communication module cost is lower than the GSM module and the Nb-lte module. Nb-lte is more inclined to be compatible with existing LTE, and its main advantage is its ease of deployment.
Finally, after the September 2015 ran #69会议协商统一, NB-IoT could be considered a fusion of Nb-ciot and Nb-lte.
According to Yuquan, chief strategy officer of Huawei Wireless network product line, NB-IoT technology has four advantages: one is coverage, NB-IoT coverage is 20 db better than traditional GSM network. If a base station can provide 10 times times the area coverage according to the coverage product, the second is to support the mass connection, under the 200KHz frequency, with the help of NB-IoT, a base station can provide 100,000 connections; three is low power, NB-IoT communication module battery can work independently for ten years without needing to charge Four is low cost, NB-IoT module target is less than 5 dollars.
Lora's main technical feature is the ability to carry out long-distance transmission of 1-20km, the city, wireless distance range in a kilometer, suburban or open area, wireless distance up to 20km. Node points can be up to million or even millions, a gateway can connect how many nodes or end-devices. The data rate range is 0.3~50kbps, and the low data rate allows battery life to reach 3-10 years.
Therefore, if you are technically contrasting, it is difficult to say which technology has the absolute advantage, the biggest difference between the two is whether to work in the authorization spectrum.
The development status of two kinds of technology
In order to successfully push the Lora agreement to global standards, an open, non-profit organization, initiated by industry leaders, was established as the Lora Alliance to bring low-power wide-area networks to the world to achieve the application of the Internet of Things, computer-based, smart cities. At present, the alliance members include multinational telecom operators, equipment manufacturers, system integrators, sensor manufacturers, chip manufacturers and innovative start-up enterprises, these members across Europe, North America, Asia, Africa and other regions.

As an early Lpwan technology, Lora has been widely used at home and abroad. Companies have started to roll out simple, low-power Lora modules and point-to-point transmission solutions to end-to-end solution providers. August, intelligent Technology, Mons technology, only the technology, the pioneer of technology and other early Lora solutions to promote the node + Gateway + cloud service solutions, so that users can choose from a stack of wood, choose from simple transmission to enterprise-class network operators of different solutions. However, because the domestic Lora program manufacturers are many start-ups or small and medium-sized enterprises, their exposure is not high, Lora has not been widely concerned.
By contrast, NB-IoT has a higher degree of exposure due to the strength of Huawei and its operators. As the leading provider of NB-IoT, Huawei provides end-to-end solutions, including base stations, core networks, chips, operating systems, and data management platforms. In addition to Huawei HiSilicon, Ericsson and Qualcomm are actively developing and producing such chips, many of the original chip manufacturers and modules are also planning to support NB-IoT this year.
Application, Vodafone launched the underground garage instruction case, Huawei in the "2015 Global Mobile Broadband Forum", after disclosing the use of NB-IoT smart meter, intelligent parking system, the "intelligent Tracking system" which integrates GPS function to manage the positioning information of the goods.
On the operator side, China Mobile has announced that it will implement NB-IoT commercially in 2017. Unicom is also planning to launch NB-IoT field-scale networking tests and business demonstrations in more than 5 cities this year, and to advance the NB-IoT commercial deployment of key cities by early next year, which is fully commercial in 2018. Domestic mainstream operators began to design the NB-IoT timetable, and foreign operators are more enthusiastic, Vodafone, Deutsche Telekom, UAE Telecom, Italy Telecom, T and other world's top operators around NB-IoT released their own development strategy and the launch of the experimental Bureau.
By contrast, it is not difficult to see that the industry giants involved in NB-IoT camps have a certain industry voice and exposure, and have a certain advantage in promoting the commercialization of NB-IoT technology.
Can NB-IoT really crush Lora?
An insider said that in exploring IoT-related application deployments, issues such as interference, which are based on the non-authorized spectrum, are only a few days away, which is enough to see the importance of authorization spectrum based. The licensing and unauthorized spectrum has also become the key to the future development of NB-IoT and Lora Technologies.
Since NB-IoT has a number of advantages for carrier-grade networks, it has the technical and industrial Foundation to deploy a nationwide network, and regulators ' recent policies and pronouncements address its policy hurdles, However, the non-authorized low-power wide-area network represented by Lora seems unable to realize the deployment and operation of carrier-grade network. From this perspective, NB-IoT can crush Lora, but the biggest feature of the internet of Things is its rich application.
Reference to the existing information and communication market, in addition to the operator's 3g/4g public network, there are public security, transportation, civil aviation, logistics, railways, security and other industries dedicated network, but also to achieve similar 3g/4g of high-speed communications, the emergence of the sea can reach, the letter Granville Communication, Putian Communications and other special network areas of outstanding enterprises and the annual market size of tens of billions of.
After the commercialization of the future NB-IoT, in addition to the operator deployment of an open, non-discriminatory access to the low-power WAN network, similar to the existing communications in the field of public network, there are still a large number of industry or enterprise users based on their own business needs to build a private network. Lora Enterprise-level network solution, will greatly expand the market category of private network, forming a broader market space.
The competition between NB-IoT and Lora is not just a game between the two technologies, but also represents the future of two types of LPWA technologies that authorize spectrum and unlicensed spectrum in the era of the Internet of things. We believe that NB-IoT will not crush Lora, but that the two will coexist together to improve the network layer of the Internet of things.
