20195Regional Common Proposals
• WRC is a Global conference organized by the ITU every 3-4 years to update Radio Regulations, the
international treaty governing the use of the radio-frequency spectrum and satellite orbits
• Each WRC prepares the agenda for the next WRC and initiates a new study cycle, in preparation
for the next WRC. Technical Studies for WRC Agenda items are done by ITU-R Study Group and
are presented in the CPM Report to administrations and the WRC.

ITU Harmonized spectrum for Emergency (PPDR) Communications
Spectrum for Narrowband Critical Communications
• 146-174, 350-370 and 380-470 MHz - UHF Band for P25 and TETRA and DMR
• 806-824/851-869 MHz 800 MHz band for P25 and TETRA and DMR
Spectrum for broadband Critical Communications
• 694-894 MHz on a global basis
• 380-470 in Regions 1 and 3 and 4940-4990 in Region 3
Resolution 646 adopted by WRC-03
and Revised by WRC-15

Administrations around the world are opening new broadband spectrum for MC Communications for Industries and Utilities
US FCC has allocated 3550-3700 MHz for CBRS . Canada considering similar rules
Germany allocated 3700-3800 MHz for enterprise broadband applications. France, Sweden, UK considering similar rules in midband spectrum
European Regulators recently modified rules to permit broadband channels in 410-430MHz in addition to 450-470 MHz and 698-791 MHz to support the introduction of FD-LTE .
Singapore regulator recently proposed opening of two slots of 5+5 MHz and one slot of 3+3 MHz for industrial and enterprise broadband in 850 MHz
China MII reserved 1447-1467 MHz for critical government communications and permitted LTE trials in many cities.
WRC -19 will consider 24-86 GHz bands for 5G

Group WRC-19 Agenda Item 1.13 Bands
Group 30 24.25 GHz – 27.5 GHz
Group 40 37 – 43.5 GHz
Group 50 45.5 – 50.2 GHz/50.4 – 52.6 GHz
Group 60 66 – 76 GHz
Group 80 81 – 86 GHz
WRC-19 main agenda is to identify spectrum
above 24 GHz for 5G
Some of the 5G Bands allocated at WRC-19 could support Enterprise and Utilities needs for Higher capacity broadband mission critical networks
Other Key WRC-19 agendas impacting Critical Communications are 1.3 for
460-470 MHz and 1.11 for Railways
In Summary, Spectrum needs of Critical Communications are continuing to grow and regulators need to look at new
approaches and higher bands
