FM & TECHNOLOGY
Now a single gateway can manage an entire skyscraper or multiple offices in a private network without added operator costs, linking securely to the cloud via end- to-end encryption while maintaining separation from corporate networks. This avoids the risk of IT systems compromising smart building performance while allowing access to analytics and machine learning in order to automate building management. These systems can also tap into public networks using LoRaWAN, linking buildings around the world to secure management systems.
This protocol reaches directly to satellites in orbit, and operators are launching constellations of satellites to monitor out-of-reach sensors leveraging LoRa from space.
LR-FHSS can also be used in the infamously crowded 2.4GHz band. With Wi-Fi, Bluetooth, Zigbee and Matter networks all competing for access, low power sensors can struggle to be heard in smart buildings. The LoRa 2.4GHz capability offers an expanded ISM bandwidth that is globally available and provides data rates up to 100kbit/s with a range of 200 to 300 metres in complex, dense environments to reliably deliver data from sensors. This allows sensors to continuously monitor machine

health, predictively scheduling maintenance and reducing unscheduled downtime.
The latest LoRa devices now include geolocation capabilities that can be used for tracking assets both inside and outside of a building. These devices sniff the 2.4 GHz Wi-Fi network packets and GNSS satellite navigation signals to track the location of valuable assets, providing additional physical security for equipment within a given area.
These deployments use open standards, which minimizes operational costs, and are part of an ecosystem of sensor and gateway suppliers and network operators that collaborate via the LoRa Alliance.
Making corporate real estate smarter via enhanced systems gives facilities managers highly targeted control of building systems and is much more straightforward than was previously possible. LoRa technology enables long reach for battery powered sensors that connect seamlessly to private or public networks. The latest enhancements and global 2.4GHz operation gives facilities managers many compelling options that make any building smarter.
