In the ever-evolving landscape of wireless communication modules, REYAX Technology has been at the forefront, specializing in high-quality solutions for over a decade.
Their latest innovation, the RYUW122 Ultra-Wideband (UWB) module, promises to revolutionize indoor positioning and distance measurement.
With its precision location capabilities and compliance with worldwide UWB radio regulations, the RYUW122 opens up exciting possibilities for a wide range of applications.
In this in-depth article, we will explore the key features and potential applications of the RYUW122 UWB module.
What is UWB Technology?
Ultra-Wideband (UWB) is a wireless communication technology that uses a broad spectrum of frequencies to transmit data.
Ultra-wideband (UWB) stands as a remarkable short-range RF technology used for wireless communication, offering unparalleled precision in detecting the exact location of individuals, devices, and assets.
In a manner akin to Bluetooth and Wi-Fi, UWB facilitates data transmission between devices through radio waves, accomplished by emitting short nanosecond pulses across an “ultra-wide” spectrum of frequencies.
How Does it measure the distance by data transmission?
UWB technology operates by generating billions of radio pulses sent at rapid intervals, forming intricate patterns across a broad frequency range, typically spanning at least 500 MHz or 20% of the center frequency.
UWB uses Time of Flight (ToF) to determine the distance between peers. ToF measures the propagation time that it takes for the RF signal to travel between the transmitter and receiver.
TOF Explained with a simple diagram
This time measurement multiplied by the speed of light determines the distance with high accuracy.
Compared to other technologies relying on measured signal strength to evaluate distance, UWB provides a higher degree of accuracy and security.
These patterns are then received and analyzed by the recipient device, which decodes the incoming signals into usable data.
Although primarily designed for rapid data transfer over short distances, the unique characteristics of UWB signals also enable precise localization of devices.
As a result, UWB-capable devices, including smartphones, sensors, and anchors, can accurately pinpoint the location of transmitting devices, such as other smartphones or asset tracking tags.
This capability paves the way for location-aware communication and services, enhancing various applications and user experiences.
UWB’s Unique Advantages
- Operates with a high bandwidth over a very wide frequency spectrum between 3.1 to 10.6 GH and has very little power consumption.
- location of UWB signals can be determined with an accuracy of less than 50 centimeters (with optimal conditions and deployment), and extremely low latency.
The RYUW122 Module Overview
The RYUW122 is a UART Interface 6.5/8 GHz UWB antenna transceiver module developed by REYAX. It supports IEEE802.15.4-2015 UWB and IEEE802.15.4z (BPRF mode) that meet worldwide UWB radio regulatory compliance.

Ease of Integration with AT Commands
REYAX Technology has designed the RYUW122 to be easily controlled through AT commands.
This user-friendly approach simplifies the integration of the module into existing systems and allows developers to quickly harness its capabilities without a steep learning curve.
Here is a short guide to using AT commands
- The RYUW122 can be set as the role of “ANCHOR” or “TAG”. The distance value will be output through ANCHOR, and the data transmission can be bidirectional.
- First, you must use the AT+MODE command to set the module as ANCHOR or TAG
- Use “AT+NETWORKID” to set the UWB network group. Only those that are set with the same NETWORK ID can communicate with each other.
- Use “AT+ADDRESS” to set a unique Address.
- Use “AT+CPIN” to set the UWB network encryption password. Only those that are set with the same encryption password can be decoded correctly.
- If you want to transmit data to ANCHOR from TAG, You must use the AT+TAG_SEND command.
- If you want to transmit data to TAG from ANCHOR and obtain the distance, You must use the AT+ANCHOR_SEND command.
- When TAG is set to the parameter of “AT+TAGD” for power-saving purposes, the “AT+TAG_SEND” and “AT+ANCHOR_SEND” commands under the ANCHOR must match the RF duty cycle of TAG.
