According to statistics, there are 52 LoRa networks covering more than 100 countries around the world. The adoption of the LoRaWAN protocol in the Chinese market mainly focuses on vertical areas such as smart cities, smart buildings/homes, smart agriculture and industry. Currently, there are 3 publicly available in China. The LoRa network was released, including the Guizhou Zhongan Cloud Network covering the entire Guizhou Province, the network of the Guangzhou Chinese Academy of Sciences Computer Network Information Center covering the Guangzhou Nansha District (803 square kilometers), and the Shaanxi Broadcasting and Television Network covering the Xi'an Beilin District. In addition, China has 16 private/test LoRaWAN ("10 GWs" networks and has installed 1,732 gateways. Its network coverage can be traced directly to NB-IoT.
(Ace) Following the announcement of the signing of the NB-IoT shared bicycle application cooperation agreement with Huawei at the beginning of the year, Semtech announced at the ninth meeting of the LoRa Alliance in Suzhou that OFO is working on LoRa devices and radio frequency technology (LoRa technology). Equipped into its bicycles to complement its licensed spectrum connection options to achieve complete network connectivity for coverage in remote areas and dense buildings.
This is the first time the LoRa Alliance has held such a large conference in China. LoRa Alliance Chairman Geoff Mulligan said, “China plays a pivotal role in the global electronics industry and is a huge potential market for IoT applications. Members have the opportunity to meet, show and communicate to promote their global business interests."
Lowest cost deployment of LPWAN technologyAfter several years of development, LoRa technology has now formed a complete IoT ecosystem from chip to solution. The LoRa Alliance has more than 500 members, including 40 Chinese member companies including ZTE. As a leader in domestic LoRa technology, ZTE launched the China LoRa Application Alliance (CLAA) in early 2016, and at the end of 2016, ZTECLAA, a subsidiary focused on LoRa technology, was established.
During the conference, Liu Jianye, vice president of ZTE Corporation and CEO of ZTE Carat, said that LoRaWAN is a technical system that is very suitable for low-cost IoT-scale applications. Whether it is CAPEX cost or OPEX cost, LoRa technology is only NB-IoT technology. One percent. At the same time, LoRa is only one percent of NB-IoT in terms of user terminal power consumption. It is reported that there are more than 850 CLAA members, with more than 100 application types and more than 40 commercial applications.

In addition to low cost, Geoff Mulligan said that other advantages of LoRa technology include wide coverage (up to 30 miles between sensors and gateways), low power consumption (up to 10 years of service), interoperability (LoRaWAN is an open protocol that enables interoperability between devices in the LoRa ecosystem) and high capacity (LoRa-based high-capacity base stations can support millions of messages per day, while a single base station can support thousands of stations) Equipment) and so on.
Technology and scene related and NB-IoT are not competitiveAs we all know, LoRa is a typical LPWA technology that uses unlicensed spectrum. In an interview with C114 during MWC Shanghai this year, Dr. Shane Rooney, Executive Director of the GSMA IoT Project, said that in the LPWA field, licensed spectrum technology will become the dominant technology in the next 1-2 years. However, he is also frank that in the field of Internet of Things, the difference between licensed spectrum technology and unlicensed spectrum technology is not necessarily at the technical level, but why a customer chooses to use a certain technology.

Geoff Mulligan emphasized that he believes that LoRa and NB-IoT are not competitive. The two technologies have different IoT applications and different concerns. Perhaps some users have already cooperated with operators or intend to cooperate with operators, then he may think that NB-IoT and other authorization technologies are more suitable for themselves. But if users want to build their own network or use the ISM band, or don't want to spend too much time focusing on SIM card security issues, LoRa will be a more suitable choice for users.
According to reports, LoRa technology currently has successful application cases in multiple markets, with a focus on eight vertical markets: industrial control, metering, environment, urban, agricultural, supply chain and logistics, healthcare and homes and buildings.
2018 will definitely be the successful year of the Internet of Things"We have reached a key historical node. Now that we have come to the second half of 2017, I think that 2018 will be the successful year for the Internet of Things." Geoff Mulligan said to us with excitement that by the end of this year, LoRa Alliance member ZTE Carat will add 10 city-level LoRa network coverage, when China will have more than 13,982 LoRa gateways and 153,000 LoRa nodes installed.
In order to promote the further development of LoRa technology, the LoRa Alliance also released its latest technical specifications during the conference. The new features in the specification include back-end node roaming and separation, which will enable IoT devices to connect to LPWANs around the world. And can achieve mutual shift between devices. This can support large-scale deployments and enable new global services such as cargo tracking.

In an interview, Geoff Mulligan said that what LoRa wants to do is not to dominate the world, but to use the right technology for the right scenario. The LoRa Alliance hopes to find the next "Zuckerberg" and help his company become a phenomenal company.
