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

2. E Band Paving the road to ubiquitous fibre access

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 1 Gbps @ 1,5 km 99.9% 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

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 Encourage spectral efficiency
71-76 GHz & GHz
250 MHz each
62.5 MHz sub-channels
Encourage spectral efficiency

11. Light Licensing Administrative Incentive Pricing
Channel size
Distance
Regional demand
‘light license factor’: approx x0.1 or x0.05
1 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
