UWB (Ultra Wideband) is a high-speed, low-power wireless communication technology that operates across a very wide frequency spectrum, typically from 3.1 to 10.6 GHz.
It uses ultra-short pulses measured in nanoseconds, allowing for highly accurate time and distance measurements. UWB is being developed globally based on the IEEE 802.15.4z standard.
Unlike location technologies based on BLE or Wi-Fi, UWB enables centimeter-level accuracy (10–30 cm), making it a core technology for real-time RTLS (Real-Time Locating Systems) in smart factories, smart logistics, smart buildings, exhibition halls, and advanced medical facilities.
UWB is also rapidly expanding as a key enabler of smart cities and Industry 4.0 by integrating with 5G/6G networks, IoT devices, and edge computing.
Technology Principle and Architecture
The core principle of UWB positioning technology lies in precise distance measurement using the Time of Flight (ToF) or Time Difference of Arrival (TDoA) of ultra-wideband pulse signals.
Similar to GPS, UWB calculates absolute distances between devices and determines 2D or 3D spatial coordinates using trilateration algorithms.
This enables high accuracy and stability even in complex indoor environments.
In the GrowSpace product line, the following positioning methods are supported:
- TDoA-based Multi-Synchronized Positioning
(Optimized for fixed infrastructure setups; ideal for large-scale real-time tracking) - TWR (Two-Way Ranging)-based P2P Positioning
(Flexible configuration; supports integration with mobile devices and lightweight infrastructure) - Hybrid BLE+UWB Positioning
(Combines the strengths of BLE and UWB to build a hybrid RTLS system}
These methods provide high accuracy and reliability across complex indoor-outdoor environments, for fast-moving objects, and in demanding manufacturing and logistics operations.
