LEAPS UWBS
LEAPS UWBS is a fully-embedded and advanced UWB Sub-System that covers a wide range of use cases. One UWB Sub-System is configurable in different modes and profiles. The UWBS can run as an Anchor, a Tag or a Gateway. The networking profiles are fully scalable with high capacity and low-power.
Key Features
Versatility makes it easy to balance the system requirements, costs, deployment time and maintenance complexity. Applications range from simple distance proximity to high-speed tracking or navigation of an unlimited receiver.
It integrates a sophisticated UWBMAC that allows adaptive clustering of the infrastructure devices, air-time reuse, slot allocation, etc. A scalable, proven collision detection, collision avoidance and collision resolution allow the system to function robustly in complex environments.
Supported measurement techniques include TWR, DL-TDoA and UL-TDoA. Integrated location engines allow the device to operate independently in the navigation mode using DL-TDoA or TWR.
Superior power management provides a long battery lifetime for both TWR and TDoA modes.
Used terminology
Anchor: Has fixed location.
Tag: Changes location, determines position dynamically with the help of anchors.
Gateway: Provides stateful information about network nodes (read/introspect), caches node information, might even collect data and track history, provides means for the application layer to interact with UWB network elements (a.k.a. interaction proxy).
Node: Network node (anchor, tag, gateway, …).
LE: Location engine.
CORE_INT: GPIO pin reserved by firmware to inform users about new UART/SPI interface events.
TLV: Type-Length-Value encoding.
