What is the RSGB?UK’s national amateur radio (AR) society
Founded in 1913; Patron is
HRH The Prince Philip, Duke of Edinburgh
Dedicated to the development of science and practice of amateur radio
Represents the interests of UK’s 60,000 licensed radio amateurs nationally and internationally
Conducts examinations
Network of 500+ affiliated clubs across UKSlide3
Scope of the sectorDefined by ITU RR Articles 1.56, 1.57 and 25Amateur service
Amateur-satellite service
136kHz – 248GHz (and more!)
Approx 70k UK licencesApprox 3.5 million amateurs worldwideSlide4
Social and economic value“Amateur” means “unpaid”High tech skill base
Technical innovation
STEM
Emergency backupCrosses international boundariesSlide5
Sector trendsDespite the www, radio (wireless) vitalComputing/radio integration
SDR technology
Weak signal activity
SatellitesSlide6
Sector threatsEMC – EU regulation and monitoring weakDomestic equipment
xDSL
PV and wind
Wireless power transfer
Loss of Microwave bandsSlide7
Use of technologies and spectrum AR spectrum allocation agreed globally within ITUNeed blocks which are relatively noise free for weak-signal long distance operation
Some ‘Primary’ status, but not enoughSatellite communications – Voice and TV
EME and other very weak signal operationDigital ATVSlide8
Expected changesDigital modes (Voice and TV)Not exclusively digitalFurther embedded software and equipment system convergence
Lowering the age profile
Remote control, automation, apps,bridging between modes, further ISS/satellite growthSlide9
Spectrum StatusUK amateurs have access to 136kHz - 248GHz Lack of Primary spectrum hinders both Amateurs and ultimately the wider UK Global harmonisation is a priority due for long distance narrowband EME and satellite usageSlide10
InfrastructureDemand highest at VHF/UHF1000 managed systems Digital/network use growingPropagation beacons to >47GHzSlide11
Spectrum sharingAmateurs self-manage a wider diversity of modesWe practice LBT, DFS, geo-aware etc - always!
Excellent sharing record with PMSE, Radiolocation, Military. Studies cover up to 79 GHz
Difficult to share with mobile broadband and ISM in secondary allocations Slide12
Spectrum trendsOngoing use/congestion highest at HFInfrastructure demand at VHF/UHFBeacons , EME etc popular in microwave bandsData links/mesh growing in microwaves
Distance records at microwave/millimetre waveMore TV in lower bands. More use in 76, 134 GHz
Smart radios – flexible Apps, bridging, codecs Growth/exploitation of small satellites, airborneSlide13
Longer termProtect amateurs’ freedom to innovate’Opportunist communications mode
Even further networking/wireless integration
Scarcer skills need encouraging
Even higher frequencies
