Oct 28 -Nov-22,

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
