SA Government Strategic Objective § The SA government has identified that the ICT industry does not contribute fully to the economy due to dominance of monopoly suppliers, lack of competition and weak regulation § Outcome 6 is identified as “An Efficient Competitive and Responsive Economic Infrastructure Network” and relevant outputs are as: – Output 1: Improving competition and regulation – v including removing barrier to entry Output 5: Communication and Information technology v Broadband cost and penetration and usage v Digital divide and rural-urban divide v DTT rollout § This has been made key issue by the President of South Africa, Jacob Zuma. Other presidents in the world have taken the same stance – e. g. President Obama in the USA. Engineering and Technology Division 4
How can the challenge be faced? § Broadband wireless access which talks to BWA spectrum § This requires policy and regulatory considerations around spectrum allocation methods and regional and global harmonisation § Migration to Digital Terrestrial Television will bring about more opportunities in broadcasting and broadband market by freeing spectrum and driving convergence at different levels – this is referred to as digital dividends Engineering and Technology Division 5
International Initiatives § A total of 1167 MHz spectrum for BWA has been identified international through the ITU. Most of this spectrum has been harmonised either internationally or regionally. § However, it has been established that the world will require more spectrum before year 2020 (an addition of 553 MHz by year 2020 of which 133 MHz must be available by year 2015). § The presidency’s office in the USA is spearheading a program to search for 500 MHz spectrum for BWA that should be made available by year 2020. This program has been endorsed by the congress. The FCC and the NTIA are working together for realisation of the program. Engineering and Technology Division 6

LICENSING STATUS OF BWA SPECTRUM IN SOUTH AFRICA Engineering and Technology Division 8
BWA bands in South Africa § South Africa has adopted almost all ITU-R designated bands for BWA and are as follows: – – – 450 - 470 MHz – suitable for coverage 790 – 960 MHz – suitable for coverage 1710 – 2200 MHz (excluding 2025 – 2110 MHz) 2300 – 2400 MHz 2500 – 2690 MHz 3400 – 3600 MHz § Licensing status for each band in South Africa is shown in the few succeeding slides. The following color coding is used: – RED - designated but not fully licensed for BWA – GREEN – designated and licensed for BWA – BLUE – licensed for BWA but some re-arranging might be required Engineering and Technology Division 9

In conclusion About 500 MHz available § We have about 500 MHz spectrum identified for BWA that is not licensed and 576 licenced (that is about 50% is unlicensed) § There about 450 individual ECS and ECNS licensees came after the famous Altech case § Therefore there is an need to licence the 500 MHz spectrum § We need to start identifying additional spectrum for BWA by 2015 § At least 100 MHz of the additional spectrum must be below 1 GHz to enable coverage and hence universal access Engineering and Technology Division 13
Migration to DTT and DVB-T 2? § Why DVB-T 2 – Enable more coverage and higher data rate through use of: v v – Low Density Parity Check for error correction coding and the use of rotated constellations Multi antenna technology to provide diversity and exploitation of the earth’s curvature Improved functionality enabled by multiple “Physical Layer Pipes” which separate configuration of each delivery stream § Opportunities – – – Fewer frequencies for more services (a 1/8 of current will be required for 5 fold the current number of services) – i. e. More freed spectrum, more choice and less cost Therefore can make additional spectrum below 1 GHz available for BWA Ability to stream IP based traffic and use of “white spaces” – providing another platform for BWA More opportunities for innovation in programming and distribution – leading to the industry contributing to the economy Physical Layer Pipes can allow localised or regional broadcasting which would facilitate community TV broadcasting and local content Engineering and Technology Division 14
How do we assign spectrum? § First Come First Serve – not suitable for high demand limited spectrum § Competitive processes (market based) – Lottery, “Beauty contest”, Auction, Spectrum pooling, some hybrid § Some Prons and Cons – “Beauty contest” and Auction can both fulfil developmental goals if designed properly (e. g. Through set asides) – economic equilibrium may be the same – “Beauty contest” more costly and time consuming and prone to human error and subjectivity – more prone to litigation – Auction allows the market to determine the value (utility function) – Spectrum pooling good for extremely limited spectrum or niche spectrum § Some Auction methods – First price sealed bid – Second price sealed bid – Simultaneous multi-round auction Engineering and Technology Division 15
Defining Auctioning Problem Mathematically (example) Given F(x): F Number of new entrants Then the goal is to: Maximize F(x) Subject to: xnew 0. 3 xtotal xmax x xmin Where x is any amount of spectrum xnew is the spectrum to new entrants xold is spectrum to incumbents xtotal = xnew + xold is the total spectrum addressed xmax is the maximum allowable spectrum for an entity xmin is the minimum allowable spectrum for an entity Engineering and Technology Division 16
