  1. C-BandNow and TomorrowTHE FIJIAN EXPERIENCE Spectrum Management Symposium 1 November 2013 @ the Tanoa International Hotel (Nadi) Prepared By Igor Zukina

  2. C-Band THE FIJIAN EXPERIENCE • Downlink: 3.7 – 4.2 GHz • Uplink: 5.9 – 6.4 GHz • ADVANTAGES: • Less disturbance from heavy rain fade • Cheaper Bandwidth • DISADVANTAGES: • Needs a larger satellite dish (diameters of minimum 1-3m) • Powerful (=expensive) RF unit • More expensive hardware • Possible Interference from microwave links

  3. C-Band Challenges THE FIJIAN EXPERIENCE • Down link reception Interference level significantly increased by: • wireless radio links (last mile broadband delivery) in some cases spreading without management and licencing • many cases of reported interferences • interferences can get reduced by cost intensive microwave filters or more directional antennas = most costly for service provider • difficult interference problem resolution as there is no spectrum licences with specific operational parameters

  4. Immediate Commitment: THE FIJIAN EXPERIENCE • Reorganise and reengineer the 2000 – 5000 MHz bands • Strictly regulate operating parameters for WiMax , LTE • Enforce spectrum management and precise licencing for all operating devices • Equipment type approval (possible mandatory) • Protect the C-band for Satellite service – continue to be primary service

  5. Future commitment: THE FIJIAN EXPERIENCE • Continue to analyse new technologies and user demand for the services in C-band • currently very high utilisation of SAT services: • All fixed SAT telecommunications depend on C-Band, • Most of broadcast linking and distribution services are in C-band

  6. C-bandLikelihood for the future : THE FIJIAN EXPERIENCE • Demand of SAT service may decrease because of presence of Fibre communication providing equal performance/cost or cheaper service. • Ku band receiving equipment using statistical signal processing (using DSP), and modern dynamically controllable satellite transponders will increase availability of the service equal to the C-band – in this case it would be more advantages for the region – smaller dishesless wind load • A large demand for last mile wireless delivery may overturn the C-band as primarily service purely based on commercial value of the spectrum and use. OR • New technology satellite focused on switched data, last mile delivery which may replace current legacy constructed satellites – may create continuum for SAT spectrum demand and protection (like 03b)
