FootnotesCurrent use
Bands having a worldwide (co)primary allocation to Mobile Servicehave most potential for spectrum designation
Not all bands with (co)primary allocation to Mobile Service may be suitable for IMT designationTherefore, detailed studies are needed to assess the suitability
22/10/20156 © Nokia 2015
Interference is key and the spectrum should be used as efficiently as is practical
Contiguous spectrum
E.g. Several hundreds of MHz of contiguous spectrum needed for a band to be suitable for Mobile Broadband
Channel bandwidth
Regulator-assigned channel bandwidths need to be assessed
ITU RR, etc Table footnotes should be examined to find out restrictions and prohibitions
Actual usage (not just allocation) of the frequency ranges should be further investigated
Channel characteristics
Channel/path loss model needs to be studied.

Current Nokia’s Views
For example:
Current activities should be focused to find ranges/bands to be studied between WRC-15 and WRC-19 (and not to find and decide on the bands to allocate)
Storyline
5G will need both cm and mm-wave spectrum. The exact amount of spectrum bandwidth requires study. Preliminary estimates based on projected 5G use case scenarios indicate that spectrum bandwidth per
22/10/20158 © Nokia 2014 - File Name - Version - Creator - DocID
be studied as wide as possible
Keep as many ranges alive as possible, especially below 30GHz
2-4 wide ranges in low (~6-20GHz), medium (~20-40GHz) and high (~40-90GHz) frequencies
5.925 – 8.5 GHz10.7 – 19.7 GHz24.25 – 29.5 GHz36 – 50.2 GHz66 – 71 GHz71 – 76 / 81 - 86 GHz
indicate that spectrum bandwidth per operator is likely to be something like:
~500MHz below 20GHz ~1GHz between 20-40GHz ~2 GHz above 40GHz.
