 
  ULtra Wide Band (UWB) is a wireless communication technology that utilizes a frequency bandwidth above 1GHz.
UWB technology offers advantages such as low system complexity, low power spectral density of transmitted signals,
resistance to channel fading, low interception capability, and high positioning accuracy. It is particularly suitable
for high-speed wireless access in dense multipath environments, such as indoor settings.
China's JJR Laboratory has obtained radio frequency testing authorization in multiple countries and regions.
It has built standard-compliant testing facilities, introduced specialized testing equipment, and assembled
a professional technical team to provide customers with a one-stop regulatory compliance testing and certification
solution for UWB products.
Products utilizing UWB technology, including but not limited to:
- Automotive digital keys
- Locators
- Trackers
- Speakers
- Radars
- Tags
- Wristbands
- Watches
- Base stations
- Human body sensors
