Luzango MFUPE IST-2012 Africa Presentation

  1. 1. TV White Spaces for Wireless Broadband in Rural Areas: the regulator, broadcaster and operator viewpoint Luzango Mfupe, Mjumo Mzyece,Tshwane Univ. of Technology Fisseha Mekuria, CSIR Meraka Institute South AfricaSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  2. 2. Motivation, Problem Area Digital Divide is a Policy Issue (WEF, 2012)  TZ and RSA ranked 123rd and 72nd in a global networked readiness index  Archaic static spectrum allocation schemes are inefficient Dynamic Spectrum Management (DSM)  Dynamic spectrum access (DSA)-based technologies have a potential to bridge the digital divide through opportunistic spectrum sharing (i.e., space, time and frequency)  Television White Spaces (TVWS) is just one such opportunity  Current research on DSA tends to focus on developed countries and is not directly relevant to developing region contextsSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  3. 3. Research Objectives Investigate/Identify/Compare/Propose most appropriate DSM approach for providing wireless broadband over TVWS Rural areas contextual constraints include but not limited: Lack of or no reliable electricity grid Large geo areas with sparsely spread pop often from low income brackets Costly tradional fixed-wireline and wireless infrastractureSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  4. 4. Research Approach, Methodology Review spectrum Primary and policies/ secondary research standards/technologi es Quantify the TVWS Spectrum availability audit/measurement campaign(s) Modelling Define technical metrics for DSA policy Analysis/compare Construct geo- location database simulate, perform Evaluate real life experiments Monitor splatter, Different methods of calc: FCC uses contours/vectors spectral utilization efficiency, economic efficiency Ofcom uses pixelationsSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  5. 5. Major Contribution(s) Proposed DSA policy will lead to reduced Cost of ICT and bridge the digital divideSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  6. 6. Telecommunications Operator’s View  Geo-location DB driven TVWS network  Bridged (TVWS -> Wi-Fi) APsSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  7. 7. Benefits to Television Broadcaster Signal coordination: (Opportunity for $) Allow, disallow rule (Trusted/Untrusted operator(s))Session <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  8. 8. Conclusion and Outlook Big potential exist to provide wireless broadband over TVWS in rural areas Open issues still to be resolved: How to define technical metrics for DSA policies? How to protect incumbent licence-holders and public safety services from potential harmful interference? How to enforce DSA policies? How to define metrics for dynamic secondary spectrum tradingSession <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
  9. 9. References World Economic Forum (WEF) and INSEAD, “The Global Information Technology Report: Living in a Hyper connected World”, Geneva, Switzerland, March 2012. Comments and Questions… Thank you!Session <No 7f>, <10/05/2012> May 2012 IST-Africa 2012 Copyright 2012 <ICSIR & TUT>
