  1. INDUSTRY CONCERNS Relevant services in 450-470 MHz Adrian Grilli Joint Radio Company Ltd Spectrum managers for the UK Fuel & Power Industries Mobile Communications (voice and data) Telemetry and Telecontrol SMAG FORUM 24 OCTOBER 2003

  2. WAN NMS Mainframe/Server “Scanning Telemetry” Outstation Scanner Network Control Centre SMAG FORUM 24 OCTOBER 2003

  3. Telemetry & Telecontrol • 4000 gas & electricity, and 8000 water ST assignments • 4000 terminals on dedicated London Electricity data system • More systems going in every day (on existing frequencies) • 24/7 – 60/365 systems • ‘continental interference’ overcome by engineering solutions • No interference problems since 31 December 1999 • Widespread geographic deployments SMAG FORUM 24 OCTOBER 2003

  4. Challenging Changes • Some equipment can be remotely re-configured over the air • Some equipment needs site visits to change frequencies and/or filters • Some sites need ‘permit to work’ before entry • Most sites governed by HSE rules on who may enter • In many cases, parallel working will be required during changeover • Predominant cost is labour cost – site visits • Logistics can be expensive SMAG FORUM 24 OCTOBER 2003

  5. Challenging Issues • Parallel working: • Spare channels? Combiners/second antenna? Space on mast? Space in cabin? Equipment cost? Is anybody else doing same? Planning cost? • National Co-ordination: • Are all channels available everywhere? • Cannot accept geographic restrictions • International Co-ordination: • Will there be power restrictions? Preferred channels? Coordination delays? • What are we sharing with: • Will we get more interference on the new channels than the old ones? • How will 12.5kHz FM, 25kHz Tetra, 200kHz CDMA share across borders? • Intermods on shared sites: • How to predict? Who is responsible for resolution? Who pays? • Interference & blocking on shared/adjacent/near-by sites: • How to predict? How to resolve? Who pays? SMAG FORUM 24 OCTOBER 2003

  6. Challenging Conclusions • The problem must be soluble, ….but • Need to identify problems in order to solve them, … and • The process will need careful preparation and planning. And oh yes … • The cost of the new equipment is the cheap and easy bit. • Need to look at operating licences in some cases (eg Magnox Electric) Some facts to ponder from reports issued in September 2003: • Average availability of power from NGT is 99.9999% • “A delay occurred in the restoration of one section of Aquila’s network due to failure of a SCADA (telemetry) link” (OFGEM Report 30 September 2003) SMAG FORUM 24 OCTOBER 2003
