WRC-2003 TOPICS • Unwanted Emissions • Little LEOs • Possible new 135 kHz Amateur Allocation • Agenda for WRC-2007(?) Radio Amateurs of Canada
BEYOND WRC-2003 TOPICS • Wireless RLANs • IMT-2000 - Next Generation • Allocations above 275 GHz • Adaptive Systems Below 28 MHz • Ultra Wide Band (UWB) • Software Defined Radios (SDR) Radio Amateurs of Canada
BEYOND WRC-2003 TOPICS • Power Line Communications (PLC) • Intelligent Transportation Systems (ITS) • Preparations for WRC-2007 Radio Amateurs of Canada
What is a WRC All About • Primarily about SPECTRUM • Formal votes are rare • Consensus the target • Result of a WRC is a new Treaty between the Member States of the ITU Radio Amateurs of Canada
HARMONIZATION of 7 MHz BAND • 7000 to 7300 kHz until 1939 • Region 1 and 3, 7000 - 7100 kHz • Region 2, 7000 - 7300 kHz • Broadcasting Review 4 - 10 MHz • Who gains? Who loses? • Six options • Will be very difficult to resolve Radio Amateurs of Canada
CHANGES to REGULATIONS • Changes to ITU Regulations • S25 Amateur Regulations • S19 Call Signs • S1 Definitions Radio Amateurs of Canada
CHANGES to S25 REGULATIONS • S25.1 Forbidden countries list • S25.2 Transmissions shall be in plain language • S25.3 Prohibition of International third party traffic • S25.4 Except when permitted ! • S25.5 Amateurs must know Morse for operation below 30 MHz Radio Amateurs of Canada
CHANGES to S25 REGULATIONS • S25.6 Countries shall verify qualifications of candidates • S25.7 Countries shall set maximum transmitter power Radio Amateurs of Canada
CHANGES to S19 CALL SIGNS • Prefix = one or two characters, identifies responsible administration (always followed by numeral) • S19.49 c) forbids combinations commencing with a digit when the second character is the letter O or I • Yemen only has prefix block 7O -- no amateur call sign allowed under RR! Radio Amateurs of Canada
CHANGES to S19 CALL SIGNS • Also affects other countries, e.g. Zambia (9I), Tanzania (5I), Yugoslavia (4O), even UK (2I and 2O) • Solution: delete S19.49 c) • Numerals not permitted in suffix • Four letters not permitted, e.g. IARU Radio Amateurs of Canada
CHANGES to S19 CALL SIGNS • Solution: “not more than four characters, the last of which shall be a letter” • Would permit, e.g., VE1234C, VE7RCMP, VE3AB3C • No confusion with call signs used in other services • It will remain for individual administrations to determine whether they will adopt any or all of the changes Radio Amateurs of Canada
PUBLIC PROTECTION & DISASTER RELIEF • WRC 95, WRC 97 • Access to 2 Metre Band Proposed • Suppressed • WRC 00 - Globally Harmonized Band • Common frequencies, interoperability • Cross-border protocols • Equipment Manufacturers Proposing Radio Amateurs of Canada
REVIEW of BROADCASTING 4-10 MHz BAND • Examine Adequacy of HF Broadcasting Allocations in 4 - 10 MHz Band • Amateur, Mobile and Fixed Services Affected • Wanted to include 7 MHz Harmonization • IARU Resisted • Standalone Agenda Item Radio Amateurs of Canada
EESS in the 420 - 470 MHz Band • Synthetic Aperture Radar Systems • Environmental Measurements • Want 6 MHz Bandwidth • 432 - 438 MHz • Affects Amateur Weak Sig. & Satellite • Feasible Solution Seems Possible Radio Amateurs of Canada
WIRELESS LANs - 5.6 GHz BAND • Amateur Band is 5650 - 5925 MHz • Low-power, Licence-exempt Devices • Interference to Amateur Service • Consequences of Amateur Interference? Radio Amateurs of Canada

RNSS in the 1240 - 1300 MHz Band • No interference to amateur weak signal or satellite operations as far as I know Radio Amateurs of Canada
UNWANTED EMISSIONS • Crowded Spectrum • One Service Interferes with Another • Satellites a Particular Concern • Could Affect Amateurs • Watching Brief Radio Amateurs of Canada
LITTLE LEOs • 135 MHz to 3 GHz • Threat for WRC-97 • Industry Rationalization • Need Changed but Threat Remains • No Support for New Allocations • Watching Brief Radio Amateurs of Canada
POSSIBLE NEW 135 kHz AMATEUR BAND • No allocations below 1.8 MHz • Considerable Interest • Successful Experiments • CEPT Countries have secondary allocation • 135.7 - 137.8 kHz, 1w eirp, 100 Hz BW • IC Decision - Seek Allocation by ITU • Problem - Not on WRC2003 Agenda Radio Amateurs of Canada
