Location is a vital component of the Internet of Things (IoT), encompassing 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 within 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, can provide outdoor location information. However, these existing technologies are not optimized for IoT asset tracking use cases due to their increased power requirements which require access to frequent charging as well as inability to work indoors. Reducing power consumption on devices fundamentally requires a reduction of compute on device, with IoT this can be accomplished by partitioning the workload between the device and harnessing the power of the Cloud. 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.

自然灾害往往没有预警,并会造成难以估量的后果。在发生飓风、龙卷风、地震、洪水或野火等灾害后,社区需要资金援助来清除碎片、提供救生紧急保护措施和恢复公共基础设施。最近通过的《2021 年美国救助计划法案》正是响应了社区的需求。该法案为联邦紧急事务管理局 (FEMA) 的救灾基金拨款 500 亿美元,以帮助州和地方政府应对重大灾难或紧急情况并灾后重建。
