Spectrum Management: Parkes & ATCA Briefing for ATUC
Spectrum Management: Parkes & ATCA Briefing for ATUC members Erik Lensson | Head, ATNF Engineering Operations 30 October 2012 CSIRO ASTRONOMY AND SPACE SCIENCE Background Eastern seaboard spectrum management, - RALI MS-31, (Parkes, ATCA, Mopra) - RFI & NBN S-band wireless access rollout - Upcoming UHF spectrum auctions - CASS RFI monitoring initiatives (Technologies & Ops)
- Implications for Parkes future instrumentation ASKAP and MRO are in the (70,687km2) Radio Quiet Zone, - Band Plan, (legally binding) and - RALI MS-32 Procedures: > MRO/RQZ spectrum issues not discussed today 2 | Spectrum Management: Parkes & ATCA| Erik Lensson RALI MS-31 FN AUS87 recognition of unlicensed (fortuitous) reception;
Goodwill coordination/negotiation; Power density thresholds; Parkes, ATCA, Mopra, CDSCC; Mt Pleasant, Ceduna; Apparatus licence only; Procedure, 5 day turnaround; [email protected] 3 | Spectrum Management: Parkes & ATCA| Erik Lensson Service Delivery Model*
*per CEO Mike Quigley @ RADCOMMS 2012 Universal Broadband - Wholesale network; - Consumers deal through local retailers; - 12 Mb/s peak user throughput. 4 | Spectrum Management: Parkes & ATCA| Erik Lensson NBN Wireless
S-band (2300 2400 MHz) fixed wireless access 3GPP LTE standard wireless technology in 20 MHz channels TDD transmissions, 40/0.66 Mb/ s down, 9/0.15 Mb/s up; Hundreds of stations across rural & regional Australia Ericsson $1.1B contract for design, build & operate (10yrs) 5 | Spectrum Management: Parkes & ATCA| Erik Lensson
ATCA & Other Observatories Mopra Mt Pleasant (UTAS) Ceduna 6 | Presentation title | Presenter name Other UHF Band$ 694 820 MHz, UHF Digital Dividend. Auction April 2013. 126 MHz in 20 MHz lots. Caps on bidders; 2500 2690 MHz ENG/TOBN vs 4G Wireless
Simultaneous auction scheduled with 700 MHz, 20 MHz lots; 1427.9 1510.9 MHz Mobile Broadband, ACMA Discussion Paper (May 2012), 19 submissions, telcos, broadcasters, government agencies & CSIRO. Pending... Midweek RFI and other new aeronautical and spaceborne emitters many in the redshift bands below 1400 MHz 7 | Spectrum Management: Parkes & ATCA| Erik Lensson Aircraft ADS-B, 1090 MHz, 200 W/@20,000
8 | Spectrum Management: Parkes & ATCA| Erik Lensson Parkes RFI Survey Nominal coverage 25 MHz to 6 GHz in 50 MHz steps Supports proposed 0.7 4 GHz broadband receiver Need deep spectral and transient surveys at Parkes; Development system based on SKA hardware + BEDLAM transient detector (Ron
Beresford, Paul Roberts, Aidan Hotan, Aaron Chippendale) Commissioning tests for full system ~end November 9 | Spectrum Management: Parkes & ATCA| Erik Lensson 8 ms BEDLAM Operations RFI/EMC Monitoring System (COTS) Rohde & Schwarz EB-500 Receiver;
20 MHz to 3.6 GHz, real-time 20 MHz FFT, scan & log; Remote web interface integrate with ACMA RADCOM database and ATNF RFI analysis software; Observer or engineer located at SOC or any observatory, can check for RFI at any site/s; One EB-500 unit purchased and evaluated; Priority: MRO, Parkes & Narrabri; 10 | Spectrum Management: Parkes & ATCA| Erik Lensson Planning Wideband Receivers Dynamic range extremely important, need to accommodate the
highest level interferers in any part of the RX passband; High 3IP LNA vs low Tsys (mutually exclusive?); Filtering (pre/post LNA)? Design with gaps in coverage? (where?, how big?); RFI sampling, canceller design; Antenna sidelobe characterisation (all-sky survey); Time invariant vs transient RFI;
