  1. 1. 1800 MHZ FIXED LINKS A Telstra Perspective ACMA Workshop 15 Nov 2012TELSTRA TEMPLATE 4X3 BLUE BETA | TELPPTV4
  2. 2. WHO IS USING 1800 MHZ FIXED LINKS? Approximately 773 fixed links in 1800 MHz band belonging to: Telstra Corp BHP Billiton Iron Ore Pty Ltd Northern Rivers TV Airservices Australia Snowy Hydro Ltd Woodside Energy Ltd Dept of Defence Newmont Tanami Pty Ltd QR Network Pty Ltd TEC Desert Pty Ltd and TEC ESSO Australia Desert No2 Pty Ltd Electranet Pty Ltd Lanfranchi Nickel Mines Pty Ltd Santos Ltd Queensland Rail Limited Robe River Mining Co Ltd Bartter Enterprises Pty Ltd Transend Networks Pty Ltd Australian Rail Track Corp Ltd Electricity Networks Corp 1800 MHz Fixed Links |Brian Miller |15 Nov 2012 2
  3. 3. WHERE ARE THE LINKS LOCATED? 1800 MHz Fixed Links |Brian Miller |15 Nov 2012 3
  4. 4. TELSTRA’S 1800 MHZ FIXED LINKS• Telstra has about 82% of the 773 links in the band• Used for the back haul of voice and data services, including Universal Service Obligation (USO) services• These links represent a significant investment by Telstra• No plans to grow the number of links in this band• The links are often daisy chained – originating from points of interconnect in regional population centers.  Many of the links may be in locations that could also be of interest for future mobile services 1800 MHz Fixed Links |Brian Miller |15 Nov 2012 4

  6. 6. MANAGING INTERFERENCE• Main challenge is managing interference from mobile base stations and user devices into sensitive fixed link receivers (high gain antennas)• Seek to avoid interference through the mutual coordination of frequencies, sites and antennas• Coordination is complicated by the misalignment of the fixed and mobile channel plans in the 1800 MHz band• An alternative option is to consider migrating the fixed link/s to a higher frequency band. But migration comes at a cost … 1800 MHz Fixed Links |Brian Miller |15 Nov 2012| 6
  7. 7. INTERIM APPROACH TO SHARING WITHMOBILE SERVICESTelstra supports the ACMA’s plans to lift Embargo 62 and facilitate theapparatus licensing of mobile services, on the following basis:• Mobile operators to coordinate with fixed link operators on a case by case basis• Commercial terms to be agreed for any changes to existing infrastructure• Equal opportunity for existing spectrum licensees to access the additional mobile apparatus licences in regional and remote areas• Assignments to an operator should be aligned (to the extent this is equitable and practical) with the aggregated frequency range that is being planned for them by the ACMA as part of the spectrum licence re-issue process 1800 MHz Fixed Links |Brian Miller |15 Nov 2012| 7

  9. 9. LONGER TERM – SPECTRUM LICENSING• Telstra intends undertaking an internal study to better understand the options for managing 1800 MHz fixed links in a spectrum licensed environment and will share its findings in response to ACMA Issue paper 2. 1800 MHz Fixed Links |Brian Miller |15 Nov 2012| 9
