Release of GTI Future Spectrum White Paper

01 Identify more frequency bands to facilitate future IMT development

02

03

Bands below 6GHz are the core bands used for IMT today, with C band being a key range

Bands above 6GHz can also be utilized by IMT and the candidate frequency ranges to be studied should be kept as wide as possible

Future Spectrum

White Paper

04

05

TDD can better fit with the large contiguous bandwidth allocation and more efficiently utilize the spectrum for high data rate services

Global harmonization of future spectrum should be targeted considering the benefits in economies of scale
