Low Latency
It transmits inputs with very low delay between input and response on the computer. As a result, mouse movements and keystrokes are processed with minimal delay.

Ultra-Wideband Explained
What Is Ultra-Wideband?
Ultra-Wideband (UWB) is a wireless technology that transmits data using very short pulses across a wide frequency spectrum. Operating in a space of its own, it enables extremely fast and precise communication with minimal interference from other wireless devices.
So far, UWB has been primarily associated with devices such as smartphones and trackers. CHERRY XTRFY is among the first manufacturers to implement Ultra-Wideband technology in high-performance computer peripherals, where fast response times, high polling rates, and exceptionally stable wireless connections are essential.
Ultra-Wideband for Input Devices Explained Simply
How Do Keyboards and Mice with UWB Work?
- Input on the Device: When a key is pressed or a mouse is moved, the electronics inside the device detect the input. A controller chip in the keyboard or mouse processes this information.
- Transmission via UWB: The controller chip converts the input data into UWB radio signals and transmits them wirelessly to a compatible receiver on the computer. UWB uses very short radio signals distributed across a wide frequency spectrum.
- Signal Reception: The UWB receiver on the computer receives the radio signals and converts them back into digital input data.
- Processing in the System: The data is then passed to the operating system, where the input is processed like a regular keyboard or mouse input. The combination of a wide frequency spectrum and short radio signals ensures stable and precise wireless communication.
Advantages of UWB for Keyboards and Mice
The Ultra-Wideband technology we're using combines low latency, high signal stability, and strong resistance to interference. Especially at high polling rates and during extended use, it offers clear advantages over traditional wireless technologies.
Stable Wireless Connection
It maintains a consistent connection even at high polling rates and during continuous data transmission. This keeps inputs smooth and reliable, even when the keyboard or mouse is used intensively over long periods.
Reduced Interference
By distributing communication across many frequency ranges, signal transmission is less affected by Wi-Fi, Bluetooth®, or other 2.4 GHz devices. This is especially relevant in environments with many active wireless devices, such as offices, home setups, competitive gaming, or LAN parties.
Power Efficiency
It transmits data using very short pulses, which can help reduce power consumption while maintaining high performance. This allows devices to deliver fast and reliable wireless communication without significantly impacting battery life, supporting longer usage times between charges.
What Are the Differences?
UWB, Bluetooth®, or 2.4 GHz Wireless
Modern keyboards and mice use different wireless technologies. Depending on the application, different characteristics are prioritized, such as compatibility, power consumption, signal stability, or low latency.
Is UWB Better Than Bluetooth® or 2.4 GHz Wireless?
Bluetooth® and 2.4 GHz wireless are well-established technologies that provide reliable wireless connectivity for a wide range of devices and use cases. Bluetooth® is valued for its broad compatibility and power efficiency, while 2.4 GHz wireless has become a popular choice for gaming peripherals thanks to its fast and stable connection via a dedicated USB receiver.
Ultra-Wideband introduces a new approach to wireless communication.
For users who demand the highest levels of wireless performance, our implementation of Ultra-Wideband technology offers compelling advantages. Its ability to maintain reliable operation in crowded wireless environments makes it particularly attractive for competitive gaming, streaming setups, and workspaces with multiple active wireless devices. Combined with low latency, high polling rates, and strong resistance to interference, it is designed for users who expect speed, precision, and consistency from their peripherals.
Rather than replacing existing wireless technologies, UWB expands the possibilities for modern peripherals and represents an exciting new option for users seeking the best possible wireless experience.
