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。
It’s been an impressive year as Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology) made significant strides toward becoming the de facto platform for the Internet of Things (IoT) solutions. According to the LoRa Alliance®, by the end of 2018, LoRa and the LoRaWAN® protocol will be deployed in over 100 countries. In addition, tens of millions of end nodes were deployed, bringing an endless number of use cases in key vertical markets including smart buildings, smart metering, smart agriculture, and smart cities. This past year represented a historic period for LoRa Technology, with several highlights that we believe are worth revisiting.
In the past several years, there has been a significant expansion of the Internet of Things (IoT) in India. Leading IoT network providers Tata Communications and SenRa have rolled out public LPWANs (Low Power Wide Area Networks) making India more interconnected. With the rise in IoT adoption and market evolution, device manufacturers are creating value-added devices such as sensors for chlorine detection in drinking water, smart manhole covers, transformer monitoring, cattle tracking, and smart cities applications.
Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology) is quickly becoming the de facto technology for carrier-grade Internet of Things (IoT) due to the technology’s ability to offer unique advantages in its low power operation and ease of scalability.
Today’s Internet of Things (IoT) market consists of various low-power wide area network (LPWAN) solutions that serve a wide range of applications and use cases. With a feature set that is well-suited for a variety of verticals, Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology) is quickly becoming the de facto technology for the IoT.
One of the hottest new terms in the technology world is ‘Edge Computing.’ If you’re not familiar with the term, the ‘Edge’ is simply a device or hub that processes data and makes decisions closer to the end device rather than sending data to the Cloud for a response. This allows for lower latency and in some cases additional security. The Edge device may still send data to the Cloud to improve machine learning (ML) models and artificial intelligence (AI) algorithms, but this may be a subset of data received at the Edge and sent less frequently.
As the Internet of Things (IoT) continues to revolutionize the way we connect and interact with our devices, there are a number of network options on which to build smart solutions. The most talked about low power wide area networks (or LPWANs) are narrow band IoT (NB-IoT) and LoRaWAN®.
