Saskatchewan Provincial Public Safety Telecommunications Network Karl Reardon, P.Eng. WBIWG – Regina Nov 2010
Discussion Topics • Background • The Solution - PPSTN • System Description • System Performance • Governance and Operations • Challenges • Q&A - Panel
Background • Many of Saskatchewan public safety users had received service through SaskTel’s FleetNet Service • Commercial service with mixed user base • 185 site, 800 MHz Trunked EDACS system • Implemented in 1992 • Notice provided in 2004 to discontinue service in 2006 – subsequently extended to December 2010 • Cancellation notice initiated inception of new province wide public safety service to meet unique public safety communications requirements
Solution – PPSTN • Three party agreement to design, build and manage a province wide-area radio network • Partnership between the RCMP, SaskPower, and the Province of Saskatchewan • Designed to support the communications requirements of public safety and public service agencies operating in the province • Police, Fire, EMS, Municipal, Federal, Utilities • Future potential consideration for public works and other supporting entities
Saskatchewan Environment / Challenges • Saskatchewan Geography and Demographics • Area: 590,000 sq km • Road Surface: >250,000 km of road surface • Cities/Towns and Hamlets: 477 • Population: 1,000,000 • Long Term System Coverage Objectives: • 97% Mobile - Major through Minor Roads • Currently ~95%) • 95% Portable On-Street in Cities/Town • Currently ~90% in 343 of 477 Cities/Towns/Hamlets
Quick PPSTN System Facts • APCO 25, VHF Trunked Radio Network • 2 800 MHz sites in Regina • 550 Agencies comprising a total of 6000 users • 229 trunked radio sites • 10 new additions in fiscal 2011 • 2 Mobile Communication Trailers • 770 Radio Channels • 208 Fractional T1 radio links • 24 Interconnect points into SaskPower Private Fibre Network • 42 Interconnect points into SaskTel commercial LANSpan backhaul service • 6 satellite backhaul Links
Mobile Coverage • Most road surfaces covered in the South. • Some gaps exist in areas without tower or power facilities • Major routes covered in North (except Points North)
Portable Coverage • Portable on-street coverage provided to 90% of population • Closure of portable on-street coverage holes would require 2x the number of radio sites. • Working to improve portable coverage in 34 areas in 2011 through a combination of new sites and vehicular repeaters
Network Backhaul • Private IP based • Backhaul to redundant NSCs provided though a combination of fractional T1 radio, SaskPower Fibre, Commercial IP service, and Satellite • Vast majority of sites have redundant backhaul paths
Mobile Communication Trailers • 2 MCT trailers w 100’ towers configured within the system • Emergency restoration, events or operations • Complete 4-channel P25 trunked site with auto-locating satellite backhaul • 2 Analogue repeaters • Cost: $500,00 per unit
P25 Vendors • Multi-vendor: • Infrastructure • Harris (M/A-Com) • Consoles • Harris (M/A-COM) • Subscriber equipment • Approved based on standardized test process • Benefits of competitive bid process • Harris • Motorola
Governance and Operations • System designed, built and operated under tripartite agreement • Executive Board • Management Committee, User Committee and Resource Committee • Parties provide assets, resources and services in a cooperative manner to support and enhance PPSTN services • No exchange of funds between parties • Core responsibility are generally broken down as follows: • RCMP: Radio system management and operation • SaskPower: Fibre and power services • Province: Facilities management
User Support • Each party supports their user base • Province supports fire, EMS, municipal police provincial users and other federal users • Provincially sponsored radio purchase program for agencies with limited financial resources. • Users supported by the province pay a flat monthly fee for system use
Challenges • Shear volume of System • P25 Specification Ambiguities • E.g. Data Specification • Portable Coverage • Additional sites are resource intensive • (~$360,000 per site in capital) • Use of Vehicular repeaters • Still working to get these working • Software • User Training “Radio Was Fun Until They Put Software In It” - Anonymous
