Due to a lack of financial resources, we unfortunately have to suspend the import of any new radio frequency and mobile phone-related articles as of now (November 27, 2017). We apologize for this inconvenience and will keep you informed.

Because we received a large number of inquiries, we set up a bank account to accept donations. With their aid, we hope to resume, at least partly, the import of newly published articles to the RF archive of the EMF-Portal. Any contribution is greatly appreciated. Thank you for your kind support!

Ultra Wide Band

  • UWB
Communications engineering. UWB is a close-up range radio technology which can cover distances up to 10 meters, used for the wireless connection of devices in the home or office. It works with a very wide band width (> 500 MHz) and extremely low transmission energy (max 10 nW allowed in Germany) in the frequency range of 6.0 - 8.5 GHz. This frequency band is already assigned to other services. Due to the extremely low transmission energy of UWB the disturbance of other devices is unlikely and therefore the frequency range can be used multiple.
