今年早些时候，Amazon 向公众开放了 Amazon Sidewalk 网络。利用 LoRa 的远距离技术，Sidewalk 信号已经覆盖超过 90% 的美国人口，Amazon Sidewalk 提供 LoRa 作为其连接选项之一，供设备制造商将 LPWAN 物联网设备连接到 Sidewalk，从而实现具有远距离社区覆盖的新型设备。在 Sidewalk 无法覆盖的美国地区或美国境外，使用新 Oxit 模块的设备可以连接到任何兼容的 LoRaWAN® 网络，从而使 AWS 客户能够将其设备连接到任何兼容的适用于 LoRaWAN 的 AWS IoT Core 或集成公共网络。此外，LoRaWAN 技术不仅能让客户连接到其他公共 LoRaWAN 网络，还能利用 LoRaWAN 部署网关，在任何地方创建网络。

最近宣布的 LoRa Basics™ 调制解调器 v4 功能版本包括一项强大的新功能——中继。它允许客户添加电池供电、易于部署的中继节点，用作网络扩展器。这些中继节点可放置在偏远位置或由于极端距离或环境而信号强度较弱的地区，使用 LoRaWAN® 连接有效扩展现有网关和网络的覆盖范围。
LoRa Basics 调制解调器 v4 功能版本通过为客户提供以下功能，彻底改变了 LoRaWAN® 终端设备的开发：
物联网 (IoT) 在整个垂直行业受到欢迎，连接设备的数量不断增长，但连接技术的格局仍错综复杂。任何一种物联网网络都做不到全面覆盖并满足所有垂直物联网用例的要求。
在短短六年的时间里，Semtech 的 LoRa Core™ 产品组合带动了全球经济和环境的变化。这项创新技术为创新提供了新的机会 – 助力企业和公民，使世界变得更美好。
资产追踪是物联网 (IoT) 部署最广泛的应用之一。到 2025 年，物联网对工厂、零售场所、工作场所、办公室和家庭的总体经济影响可能高达 6.3 万亿美元， according to McKinsey Global. A variety of industries, including home and building, healthcare, agriculture, and food services in addition to the industrial and logistics markets, are investing in smarter technologies to replace siloed legacy systems with automated asset management solutions. Many existing geolocation applications are power hungry and require multiple devices, software and services from multiple vendors, resulting in increased complexity and cost.
As Internet of Things (IoT) customers discover the benefits of LoRa® devices for applications as diverse as water metering, smart lighting or tracking rhinos, there is increasing demand for “location of things” services. Location is a vital component of the IoT that encompasses the ability of things to sense and communicate their geographic position. Location data helps organize, track and account for the billions of Internet-connected devices based on sensors and other location-centric elements in them. The ability to capture location data forms the basis of location-based services, and starts with the physical radio frequency (RF) technologies that interact with the world around them. Several technologies, such as GPS, LoRa and others, are able to provide outdoor location information. However, for precise indoor location where GPS has no tangible reach, and to enable continuous location detection or tracking, indoor positioning systems (IPS) technologies such as Wi-Fi come into play.
The Internet of Things (IoT) is a truly massive phenomenon. Revenue numbers from market projections for IoT are staggering - Market Watch predicts that IoT will be worth $2.488 trillion by 2022.
Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology) is a proven long-range, low-power solution for Internet of Things (IoT) that gives system integrators the necessary features to deploy interoperable IoT solutions worldwide. In 2019, it is expected that there will be over 70 countries with public LoRaWAN®-based networks deployed, and over 200,000 gateways globally, with the capacity to support over 1 billion end nodes*.
