The approval of 6Ghz spectrum for wi-fi 6E use in Europe is governed by the European Commission decision 2021/1067/UE from 17 June 2021.
This Decision harmonises the conditions for the availability and efficient use of the 5945-6425 MHz frequency band for wireless access systems including radio local area networks (WAS/RLANs).Commission Implementing Decision (EU) 2021/1067
By 1 December 2021 Euroean member states had to make available the 5.945-6.426 Ghz frequency band. The deadline expired and as of now, only the Netherlands have harmonized it (23 December 2021) and Ireland (11/1/2022).
Frequency band allocation in Italy is regulated by the Piano Nazionale di Ripartizione delle Frequenze (PNRF) from the Ministry of Economic Development. The latest PNRF is from 2018 and does not allow 6Ghz for WAS/RLAN.
An open consultatin on a new PNRF draft (which includes the 5.945-6.426 Ghz frequency band use) is underway with a deadline at 31 January 2022. The timetable after the consultation closes is not known.
It is possible that an updated PNRF will be published in the first months of 2022, opening up the 6Ghz frequency band in Italy and making wi-fi 6E possible in Italy.
I will follow the developments closely.
