WDS - ACMA Lower Microwave Band Changes - Nov 2010

  1. 1. ACMA Band Changes to Allow 28MHz Channels for HighCapacity PTP Links at <5GHz Patrick Hooper RadioComms Connect Exhibition – Nov 2010
  2. 2. Agenda ACMA Documents Summary of Changes Impact of Changes Benefits on the Changes
  3. 3. ACMA Documents Stakeholder Survey 2006 • http://www.acma.gov.au/WEB/STANDARD..PC/pc=PC_311002 – Survey Released in April 2006 – Consultants Report May 2008 – Spectrum Engineering IFC 38/2010 • Proposed changes to channel arrangements for fixed point-to- point links in the lower microwave frequency bands • http://www.acma.gov.au/WEB/STANDARD..PC/pc=PC_312337 • Released October 2010 • Responses Close 10th December 2010
  4. 4. Lower Bands The lower microwave point-to-point fixed link bands include the: • >1.5 GHz (1427-1535 MHz) band; • >1.8 GHz (1700-1900 MHz) band; • >2.1 GHz (1900-2300 MHz) band; • >2.2 GHz (2025-2285 MHz) band; and • >3.8 GHz (3580-4200 MHz) band Current Availability
  5. 5. 1.5GHz Changes Proposal • Low Capacity Point to Point links • The proposal is to introduce from the ITU-R F.1242 Recommends 3 arrangements: – 2 x 1 MHz bandwidth channels (paired); – 4 x 0.5 MHz bandwidth channels (paired);and – 8 x 0.25 MHz bandwidth channels (paired); Maybe impacted by LTE services in the future
  6. 6. 1.5GHz Changes
  7. 7. 1.8GHz Changes Provide availability for 28 MHz bandwidth systems in the band, it is proposed to develop arrangements that provide for five 28 MHz channel pairs
  8. 8. 1.8GHz Changes
  9. 9. 1.8GHz Changes
  10. 10. 2.1/2.2GHz Changes It is proposed to create two 28 MHz channel pairs overlaying the 2.1 GHz band The assignment of these channels will be in competition for spectrum with new public mobile telecommunications services (PMTS) • Telstra and Optus just announced new licensed in these bands around 2300 licenses
  11. 11. 2.1/2.2GHz Changes
  12. 12. 2.1/2.2GHz Changes
  13. 13. 1.8 / 2.1 / 2.2 Possible Future Issues Wireless access services in regional and remote areas as services expand following population growth, PMTS in the 2 GHz band The ACMA Five-year Spectrum Outlook 2009-2013 noted that the ACMA is currently investigating spectrum requirements for GSM-R for modern train protection systems in the 1.8 GHz band The bands 1980-2110 MHz and 2170-2300 MHz are under consideration as options to deliver long term spectrum arrangements for electronic news gathering (ENG) as a part of the review of the 2.5 GHz band. Proposals include providing ENG access in capital cities and surrounding areas
  14. 14. 3.8GHz Changes Maintain the existing 40 MHz channel plan Develop new arrangements over channels 1’, 2’, 3’ that allow the use of TTD point to point links in low and remote density areas
  15. 15. Impact of Changes More Low Capacity Point to Point link at 1.5GHz Capability to provide High Capacity (>STM-1) Point to Point links in remote areas • 5 x 28MHz Channels in 1.8GHz • 2 x 28MHz Channels in 2.1/2.2GHz TDD Links in 3.8GHz
  16. 16. Benefits of Changes A Lower Cost Solution For High Capacity Regional PTP Backhaul • Low Frequencies Can Utilize Grid Antennas – Reduce Tower Requirements • Low Frequencies Have Excellent Propagation – Increase Link Distances – Reduce Number of Towers Remove Need to Move to 6/7GHz for STM-1
