  1. E-band: A technical overview Future Wireless Technologies Forum

  2. E Band Paving the road to ubiquitous fibre access Graham Beneke - Multisource Telecoms (Pty) Ltd

  3. Spectrum Management • Preventing and mitigating interference Graham Beneke - Multisource Telecoms (Pty) Ltd

  4. E band becomes viable • Advances in semiconductor device technology, resulting in commercially-available E-band cost-effective MMICs. • Increased congestion in the  microwave bands (6-38GHz) • Unprecedented need for high capacity in mobile networks Graham Beneke - Multisource Telecoms (Pty) Ltd

  5. Performance • 1 Gbps @ 5 km • 99.9% availability • 1 Gbps @ 1,5 km • 99.99% availability (South African weather) Graham Beneke - Multisource Telecoms (Pty) Ltd

  6. Performance (2) • Less impacted by fog / dust / smog than FSO • Front-To-Back ratio of more than 50dB • Beamwidth <1 degree • Wide channels for high capacity • Spectral / Channel reuse in close proximity Graham Beneke - Multisource Telecoms (Pty) Ltd

  7. Technical Challenges • Trade offs between • Spectral efficiency and radio complexity • Power consumption and bandwidth • Modulation scheme and distance • Ultimately… COST Graham Beneke - Multisource Telecoms (Pty) Ltd

  8. Pseudo-Light Licensing Works • Multiple 17 GHz links • Adjacent on highsite • Channel re-use within 10 degrees • Informal registration with distributor • Fails when other vendor equipment is deployed • BUT interference issues mutually resolved Graham Beneke - Multisource Telecoms (Pty) Ltd

  9. United States Model • 71-76 GHz & 81-86 GHz • No mandatory channelisation • Feasible for wide-band, simple modulation • Channels of 1+ GHz Graham Beneke - Multisource Telecoms (Pty) Ltd

  10. European Model • 19 channels per band • 71-76 GHz & 81-86 GHz • 250 MHz each • 62.5 MHz sub-channels • Encourage spectral efficiency Graham Beneke - Multisource Telecoms (Pty) Ltd

  11. Light Licensing • Administrative Incentive Pricing • Channel size • Distance • Regional demand • ‘light license factor’: approx x0.1 or x0.05 • 1 Gbps @ 1 km must be <R5000 pm • Compete with typical dark fibre costs Graham Beneke - Multisource Telecoms (Pty) Ltd

  12. Light Licensing (2) • No regulator input for registration • Initially – no automated radio planning • Simple GIS database • Flexible billing (monthly & automated) • Order of application/registration • No block assignments, all links registered Graham Beneke - Multisource Telecoms (Pty) Ltd
