The Internet celebrity airship of the 2018 Hangzhou Cloud Conference, equipped with LoRaWAN gateway, together with the ground gateway, forms the sky Internet of Things service from heaven to earth, which has received a lot of attention. Its main core is the Link WAN Iot network management platform, which provides gateway management and fast device access to the cloud, making it very easy for airships to mount the gateway.
This year, Alibaba Cloud IoT Business Division announced the joint construction of LoRaWAN man with Zhejiang Unicom, using the independently developed Link WAN IoT network management platform, which is one of the industrial chain layout after Alibaba joined the LoRa Alliance, Link WAN has also become an important domestic LoRaWAN access platform. It is compatible with international standards and supports large-scale and high-concurrency access requirements.
What is LoRa technology?
In 2012, Semtech acquired Cycleo, a French company that owned LoRa IP. In August 2013, Semtech released to the industry a new sub-1ghz spread spectrum communication chip named LoRa, with a maximum reception sensitivity of -148dbm. It focuses on the wireless communication market of the Internet of Things with long distance and low power consumption. The technology works in unlicensed bands around the world.
LoRa technology can perfectly solve the problem of long distance and low power consumption. The transmission distance in complex urban environment can exceed that of traditional cellular network, even up to 15 kilometers in open areas. In certain conditions, the distance of 100 kilometers has been successfully achieved, and the penetration is strong, and there are signals in many harsh environments. Support narrowband data transmission, network communication cost is very low; Due to low data transfer rates and a variety of power-saving technologies incorporated into the network design, LORA-BASED devices consume very little power and can last for years or even more than a decade on battery power.

What are the highlights of the gateway on the airship?
The airship is equipped with waterproof and dustproof IP67 LoRaWAN gateway, which forms the IoT network with the exhibition ground station through the Link WAN platform of Alibaba Cloud IoT.
The sky station uses an omnidirectional fiberglass antenna, with a maximum transmitting power of 24dBm and a maximum receiving sensitivity of -140dbm (SF12,125KHz). It can simultaneously process SF7-SF12 frequency spread channel.
Receiving and sending range as far as 30 kilometers away, up to 40,000 meters high, down to 20 meters basement, so that every inch of land can be connected.
Ali cloud Link WAN network management platform used to do what?
Through ali cloud Link WAN platform can rapid deployment features, access gateway only need three steps, in combination with the airship can be empty for a long time, the height of the ideal guarantee long-distance communication performance, the network management platform interface visual debugging, greatly shorten the engineer mount on the gateway boat of time, after the access to the data acquisition and analysis, The platform can also be timely forwarded to Ali Cloud big data service components for analysis, thus providing full-link Ali Cloud data services to users.
What are the characteristics of Ali Cloud Link WAN products?
Aliyun Iot network management platform provides four capabilities: gateway management, node management, network maintenance, traffic calculation.
Gateway management can simplify the operation of the management operation, access gateway in three steps to complete, lower the threshold so that everyone can operate the network; Node management capability, compatible with the latest LoRaWAN standard protocol, users can collect massive sensing data and subscribe to data streams through binding of access credentials; Network maintenance ability, LoRaWAN protocol layer in the platform visual management, channel monitoring and alarm system ability, help users instantly maintenance network; The platform uses Aliyun big data computing and real-time traffic statistics to ensure the real-time and accurate operation of the network.
These capabilities enable users to purchase LoRa gateways from the market, build and operate their own LoRaWAN networks, and enable developers who do not have to pay for gateway construction to purchase LoRa communication modules from the market to access networks, such as Internet of Things connections in the campus, which can be built in one day with three gateways deployed.
“Now every home has WiFi, and in the future, every business will have LoRa!” BeJo, product leader of Aliyun Link WAN, said that the massive connection of the Internet of Things must occur in the low-power wide-area connection technology. As LoRaWAN platform with the best performance in China, it is enough to meet the massive device access capacity and provide users with the most inclusive connection.
It is understood that Ali Cloud Link WAN has been successively landed in the main urban area of Hangzhou, Hongshan Town and Cainiao Logistics Park, covering an area of more than 500 square kilometers. It supports the deployment of projects of different sizes as required, and the application scenarios continue to be rich.
