The NGMN White Paper on 5G mobile identified the critical importance of spectrum availability for delivering the vision for 5G. To support the new applications and services expected from future IMT, additional new bands will be required. Operators should be able to deploy 5G in their existing mobile bands identified for IMT. While access to additional spectrum above 6GHz is of interest, low frequency spectrum below 6GHz is essential for an economical delivery of mobile services. Therefore, priority should be put on making more spectrum in those low bands available and using it more efficiently.
