基于 LoRaWAN® 的物联网 (IoT) 在全球部署，并且部署数量每年都在持续增加。2019 年，所有低功耗广域网 (LPWAN) 的 40%* 预计在 Semtech 的 LoRa® 器件和无线射频技术（LoRa 技术）上运行，基于 LoRaWAN 的网络目前覆盖大约 100 个国家/地区。特别是在亚太地区，专家预计所有物联网连接器件的数量将从 2015 年的 31 亿台跃升至 2020 年的 86 亿台。下面介绍了该地区最近的一些创新 LoRa 技术用例。
LiveCare is a LoRa-equipped bio-capsule developed by SK Telecom which is implanted into a cow’s gastrointestinal tract to monitor a variety of health indicators. The LiveCare device is shielded from environmental tampering by its strategic position inside the cow itself. Ranchers can check the data transmitted from the devices for anomalies in a cow’s body temperature and other vitals to detect the onset of disease, estrus and to forecast delivery of calves. By shielding the herd from disease and better managing their cows, ranchers can bet on healthier cows, resulting in higher quality of milk and meat, and better business outcomes.
Kiwi Technology has long been an Asian leader in the field of IoT. Previous LoRa-based smart city solutions from Kiwi have been deployed in Indonesia, Taiwan, Japan, and China among others. Recently, Kiwi announced its collaboration with Precise Digital Economy, Thailand’s largest electricity facilities group, with the goal of developing a smart city network of LoRa-based sensors to better regulate public utilities, including electricity. The network will reduce operational costs associated with maintenance, and help Thai cities use utilities more efficiently.
A long-time proponent of LoRa Technology, Australia’s National Narroband Network Co. (NNNCo) recently announced the roll out of a new LoRaWAN-based network to help cotton farmers better reap the benefits of their hard work. Through a collaboration with a major Australian agriculture company, GoannaAg, the expansion adds about three million hectares (7.4 million acres) to NNNCo’s existing network coverage.
该网络将用于为种植者带来低成本的云连接传感器和数据分析，利用基于 LoRa 的探头收集的土壤湿度数据、当地天气数据和卫星图像，以优化灌溉计划。更智能的灌溉计划可减少水浪费和增加种植者收入。
In July of 2018, the Philippines’ leading IoT solution provider, Packetworx, announced its expansion of LoRaWAN-based network coverage in the country with 2,500 new LoRa-enabled gateways. This project was a joint effort with The Things Network, and is expected to bring IoT connectivity to the Philippines for a number of innovative applications – from smart building and city, to industrial applications.
Additionally, Packetworx has shown its commitment to the continued growth of the LoRaWAN protocol by launching LoRaWAN Academy programs at 100 educational institutions nationwide. These programs give engineering students first-hand experience with LoRaWAN-based IoT technology, providing them valuable skills which make them attractive candidates to future IoT employers.
In 2016, New Zealand’s KotahiNet teamed up with LORIOT to bring LoRaWAN-based network accessibility to half of the country’s population. Originating in the country’s capital of Wellington, the network is used for a range of applications, from automatic weather notifications for farmers, to tracking of lost boats and stolen beehives. In an unique use case, New Zealand-based EcoNode utilizes the network to assist in conservation efforts of at-risk species. Rather than manually inspecting habitats and traps, LoRa-based IoT devices and the Cloud automatically notify conservationists if species are trapped or threatened – saving time and money.
