LoRaWAN global development trend
The LoRa Alliance is in good shape
Although NB-IoT is coming aggressively, LoRaWAN is also developing quite fast. According to data released by Lux Research in 2017, as of 2016, about 34 countries around the world have deployed LoRaWAN technology. According to the latest data from the LoRa Alliance, as of May 2018, about 100 countries around the world have deployed LoRaWAN. The internet. Alibaba’s figures show that my country has built or transformed more than 1,000 LoRaWAN networks. Alibaba Cloud’s Internet of Things platform has more than 1 million Internet of Things developers across the country. The LoRaWAN network relies on more than 10,000 base station addresses. Among them, the metropolitan area network coverage using LoRaWAN technology and the operator's network has been deployed in Hangzhou and Ningbo, and it is expected to be commercialized in August 2018.
LoRa Alliance Ambassador Bai Fengjia
At the 2018 Shanghai World Mobile Conference, LoRa Alliance Ambassador Bai Fengjia (Kenny Pai) said that the LoRa Alliance has grown very rapidly since its establishment more than two years ago. "There are currently 83 network operators, and more than 100 countries around the world have deployed LoRaWAN networks. There are telecom operators, network operators, and private independent organizations in the LoRa ecosystem. There are more than 500 LoRa Alliance members. China has 35 members."
As a non-profit organization, the members of the LoRa Alliance are composed of users and customers, and their responsibility is to assist in formulating and developing LoRa technical standards represented by LoRaWAN. "The LoRa Alliance hopes to establish a standard in the industry. The use, communication and information interaction of all products are realized through a common platform. The main function of the LoRa Alliance is to formulate, maintain and strengthen the functions of the LoRaWAN network." Bai Fengjia explained Responsibilities of the LoRa Alliance.
LoRaWAN features outstanding
In the low-power wide area network (LPWAN) standard, LoRaWAN features very prominent. First of all, the battery life is long. "The entire architecture is very power-efficient. Taking the water meter application as an example, the battery life can be maintained for ten years. LoRaWAN can meet the needs of application scenarios that do not require battery replacement for ten years."
The second is the long distance. The network built by LoRaWAN covers a large area. "Traditional short-range wireless communication technologies, such as Wi-Fi and Bluetooth, can only range from a few meters, tens of meters or hundreds of meters. Under the framework of LoRaWAN technology, data transmission can be transmitted to ten kilometers away."
LoRaWAN advantage
The cost of the LoRaWAN solution is also relatively low. Due to the simple structure, low material cost, and use in unlicensed frequency bands, the deployment and operation costs of LoRaWAN are very low.
In addition, when deploying a LoRaWAN network, users can build a private network or a public network according to their needs. In terms of security, LoRaWAN will encrypt at the gateway level and the data level to ensure the security of user data.
Speaking of application status, Bai Fengjia introduced that LoRa Alliance member companies have provided many vertical market solutions, with many application cases in smart cities, smart homes, smart agriculture, and smart fire protection. Wang Yunci, Marketing Director of Alibaba's Internet of Things Division, cited several specific application cases that Alibaba has implemented. In the Hongshan Internet of Things Town in Wuxi City, Ali extensively uses LoRaWAN-based transmission technology and Internet of Things communication protocols to manage the city. "We have deployed a large number of Sensors in Hongshan, and through the LoRaWAN protocol, the data is deposited on the core platform of Alibaba's Link WAN Internet of Things for unified management."
Ali blessing
In a rookie logistics park owned by Ali, LoRaWAN technology has been applied to park management. “The total building of the Cainiao Park is about 200,000 square meters. We used four LoRaWAN micro gateways to perfectly cover the 200,000 square meters of the park.†Wang Yunci told TechSugar that in this Cainiao logistics park, in addition to In addition to LoRaWAN's infrastructure such as smart water meters, smart meters and smart manhole covers, there are also some customized solutions for logistics applications.

For example, cargo stacking height detection, this program uses radar to scan the space horizontally. Once the cargo height reaches or exceeds the radar alarm level, an alarm will be triggered. The height data is transmitted to the platform through LoRaWAN technology, and the staff monitors the cargo stacking accordingly. The degree of security.
Another application is transportation vehicle scheduling and location management. All transport vehicles must take a card before entering the Cainiao Park. This card integrates GPS positioning and LoRaWAN modules. When the vehicle is at any location in the park, the GPS module will send the location information to the cloud platform, and the administrator The cloud platform can be used to manage and dispatch all loaded vehicles in the park. "This is a very simple method. You can use LoRaWAN technology to realize the scheduling and positioning management of vehicles in the entire park without the need to install GPS separately on the car."
Wang Yunci said that Alibaba will accelerate the deployment of the Internet of Things platform represented by LoRaWAN technology across the country. "The Internet of Things application practice in the Cainiao Logistics Park has been successful, and we will promote it to Cainiao's parks across the country."
