What You Need to Know About UWB

Ultra-Wideband (UWB) is a short-range radio technology that excels in precise location tracking, capable of accuracy within just a few centimeters. This technology operates over a broad spectrum, typically exceeding 500 MHz, which allows for low-energy, high-bandwidth signaling across a wide frequency range from 3.1 to 10.6 GHz. The distinct feature of UWB is its use of time-of-flight measurement for data transmission, sending up to one billion pulses per second, which are used to determine the exact time it takes for these pulses to travel between devices.

Key Characteristics of UWB:

  • Range and Accuracy: UWB can effectively operate within 30 to 600 feet, offering localization accuracy between 0.1 to 0.5 meters.
  • Frequency and Speed: It utilizes a frequency range of 3.1−10.6 GHz with a data transfer speed equivalent to the linear speed of light, approximately 0.3 m/ns.
  • Low Interference: UWB's operation at very low power levels minimizes interference with other wireless technologies, making it highly reliable for secure applications.

Applications of UWB:

UWB technology is increasingly being integrated into modern devices for applications such as secure vehicle access, smart home control, and precise asset tracking, as seen with products like Apple AirTags. The technology's ability to provide highly accurate location data also makes it invaluable for preventing relay attacks, a common method used by thieves to gain unauthorized access to vehicles.

For developers and users interested in utilizing UWB, it is essential to ensure devices are compatible, typically requiring Android 12 or higher with specific UWB hardware support checked via PackageManager#hasSystemFeature("android.hardware.uwb"). Additionally, secure session management, using mechanisms like Scrambled Timestamp Sequence (STS), is crucial for maintaining the integrity of data transmissions.
