The European Commission adopted rules specifying conditions for using ultra-wideband (UWB) technology in mass-market, consumer electronics (laptops, mobile phones, digital cameras, TVs…). 
The goal is to establish a single market for UWB devices in the European Union. UWB devices can transmit data at very high rates by “spreading” the signal over very broad ranges of the radio spectrum.
The technical conditions in this decision, which must be applied within the next six months throughout the EU’s 27 Member States, were developed following extensive compatibility studies between UWB and all other spectrum users that could potentially have been affected. The studies were done by the European Conference of Postal and Telecommunications Administrations (CEPT) for the Commission.
