Slide 1: Can public safety share wireless infrastructure with utilities & the transportation sector?
Can public safety share wireless infrastructure with utilities & the transportation sector? Robert Horvitz Email: horvitz@volny.cz
Slide 2: Public safety in Europe mainly uses TETRA
Public safety in Europe mainly uses TETRA Exceptions: • Cyprus (pre-TETRA analog) • Czech Republic (patchwork of TETRAPOL & TETRA) • France (TETRAPOL with some analog VHF for EMS & fire) • Italy (build-out halted due to economic crisis) • Latvia (ASTRO 25 network) • Malta (pre-TETRA analog) • Romani
Slide 3: Some use of TETRA by utilities & transport sector; further uptake possible
Some use of TETRA by utilities & transport sector; further uptake possible • Croatia’s HEP (electricity/gas/heat) • Czech Republic (public transport) • Denmark (railways, Copenhagen transport, energy) • Finland (Helsinki energy) • France (national railway) • Germany (airports, public transport) • Lu
Slide 4: But…
But… • TETRA’s cost is an obstacle • Utilities & transport have slow equipment replacement cycles • GSM-R has strong support among railways • GPRS has “good enough” cost/bandwidth ratio for smart metering, traffic management – License exempt UHF (e.g. 863-876 MHz) also good enough for routine utilit
Slide 5: Sector Requirements: bandwidth, data speed, simultaneous users
Sector Requirements: bandwidth, data speed, simultaneous users 100Mn ‘Normal’ operation, 24x7x365 10Mn Only in major disasters & emergencies 1mn PPDR: PPDR: surveillance Future road 100k voice & & full motion & rail: full low-speed data video for Utilities: motion video 10k for all emergency police
Slide 6: Utility requirements (electricity, water, gas) - 1
Utility requirements (electricity, water, gas) - 1 • Reliable, resilient, delay-less networks for critical infrastructure: high voltage electricity lines, transnational gas pipelines, LNG ports, nuclear power plants (including fuel/waste cycle) - Fixed lines preferred for reliability & 5-10ms SCADA
Slide 7: Utility requirements (electricity, water, gas) - 2
Utility requirements (electricity, water, gas) - 2 • Mobile voice needed for dispatch & communication with repair & maintenance crews • Video (slow-scan & full-motion) needed for access control • All utilities need resilient radio services to co-ordinate recovery from outages & disasters - if depend
Slide 8: Differences among utilities - 1
Differences among utilities - 1 Electricity • Society/economy increasingly rely on constant flow of electricity; short-term gas & water interruptions are tolerable • Electric power outages have cascade effects on other vital services (e.g. mobile telephony, broadcasting & Internet) so response to di
Slide 9: Differences among utilities - 2
Differences among utilities - 2 Gas, water & sewage • Infrastructures mostly buried, so radio’s role is limited • Gas utilities use radio (voice & sensor data) for security & to manage repairs • Water utilities use short, very low bandwidth data bursts to gather information from vast sensor networks
Slide 10: Transport sector
Transport sector “Mission critical” = accident/injury prevention Radio’s main value: facilitate routine operation, smooth traffic flow Many emerging/futuristic concepts. Today’s common applications: • GPS navigation • RFID toll collection • Traffic management • Zone access controls (congestion • Sig
Slide 11: Transport sector: GSM-R
Transport sector: GSM-R • Railways would gladly use this technology for 20-30 more years – but if commercial cellular phases out GSM, that may not be possible • GSM-R is voice-centric but uses GPRS for rail traffic management: – Driverless trains & info services for passengers depend on sensors more
Slide 12: Differences among PPDR sectors: Police
Differences among PPDR sectors Police • Primary need: reliable, secure, authenticated, low-latency voice, with – Priority levels, DMO, PTT, all-calls for dynamic user groups – Dispatching & control room links for monitoring/support – Mobile local hubs & control centres, including for UAV / AGA – Tac
Slide 13: Differences among PPDR sectors: Fire
Differences among PPDR sectors Fire • Radio signals must penetrate buildings • Local data links for infrared cameras, motion sensors, remotely controlled robots & scouts, etc. • Access to building plans, HAZMAT/flammable materials databases • Handsets must be: - Usable with gloves & face masks on -
Slide 14: Differences among PPDR sectors: Emergency medical
Differences among PPDR sectors Emergency medical • Rapid dispatch with on-route review of victim’s reported condition & medical history • Value of broadband for onsite medical emergency care increasing rapidly: - Imagery for telemedicine & paramedic guidance - Onsite vital signs monitoring, sonar sc
Slide 15: Differences among PPDR sectors: Rescue/disaster recovery
Differences among PPDR sectors Rescue/disaster recovery • Air-ground-air important for urgent transport, flooding, coastal waters, mountain & off-road rescue • Foreseeable growth in use of surveillance UAVs/drones for search & ad hoc wireless communication coverage • Voice still dominant but video/d
Slide 16: Conclusions
Conclusions • Because various bandwidths & radio propagation characteristics are desirable, many different networks are already used within each sector & subsector – Therefore, a single comprehensive solution for all sectors is unlikely to be acceptable • Video drives the need for broadband, but som
