The Office of Electronic Communications (Urzad Komunikacji Elektronicznej, UKE) in Poland has issued 3.5GHz spectrum to the winning bidders from its 5G frequency auction in October this year. 

Mobile network operators (MNOs) Orange, Play, T-Mobile and Plus were all successful in gaining 3.5GHz licences and have now been issued 100MHz of spectrum. The first base stations supporting the new band are expected to go live early next year.
