Indoor Asset Tracking
We tackle LPWAN asset tracking head-on
We are not afraid to do mobile. Most LPWAN technologies boldly proclaim their suitability for fixed use cases like meter reading because it’s easy. But it’s rare to find a LPWAN vendor touting their mobile asset tracking capabilities, much less support for GPS or multi-year battery life.
Why? Mobile is just harder! Unpredictable RF obstacles and terrain, a wide variety of use cases, and situations where GPS isn’t always available. Combine these challenges with LPWAN technologies that cannot realistically support GPS or whose batteries fail in a matter of days, it’s no wonder LPWAN vendors stay away. Most importantly, mobile requires a networking stack that supports certain features required by mobile that may be less relevant in fixed use cases, like Automatic Repeat Requests for messages that don’t arrive at their destination.
We launched Haystack after spending years solving medium-range mobile asset tracking challenges for the defense sector and kept this at the forefront of our thinking when designing DASH7. Today we integrate DASH7 with the latest long-range radios and the most advanced low power GNSS/GPS receiver to enable the most convenient, high performing, and affordable mobile asset tracking solution in the marketplace today.
Our approach to real-time location also enables multiple approaches to real-time, low power geofencing and alerts. GNSS/GPS can radically simplify this task but RSSI- and TDOA-based approaches can also support geofencing, albeit with less location granularity.
How only Haystack can support real-time, low-power GNSS/GPS location
• A-GPS provides “hot start” location acquisition – like a GPS cheat sheet – to endpoint, minimizing power draw.
• Haystack gateways multicast A-GPS datagrams to nearby endpoints
• Location acquisition time is usually ~2-3 seconds with ~3 meters accuracy
