background1
Background
  • Seychelles
    • Population: 79,089
    • Sea Area: 1,000,000 km2
    • Land Area: 444 km2
    • Islands: 115
  • Outer Islands connected via VSAT.
  • Inner Islands connected by microwave and RUTEL (2.1-2.4 GHz) links.
  • Telecommunication Indicators
    • Teledensity: 26.9%, inclusive of fixed cellular terminals (FCT)
    • Mobile density: 56.6% (more than X2 of fixed)
    • Household penetration: 64% (vision is 100% - a phone in every house)
    • Internet subscribers: 3332 (using 6 Mbps downlink and 2.5 Mbps uplink)
  • Telcos: Duopoly (December 1998) – CWS (incumbent) and AirTel (new entrant) – both have International gateways.
  • ISPs: Duopoly (December 2000) – ATLAS (incumbent via CWS) and KOKONET (new entrant – VSAT).
  • Internet access: Dial-up, ISDN, DSL, lease line, wireless access (2.4/5.7 GHz ), VSAT, cable (shortly).
  • Lease lines tariff is $400 per month (basically a monopoly with CWS) + ISP charges.

regulatory aspects
Regulatory Aspects
  • 2.4-2.5 GHz (802.11b)
    • Licensed to ISP (New entrant) – $1,000 annual license fee.
    • Last mile and only low broadband users (PtMP).
    • FCC rule 47CFR, Part 15.247 for ISP (EIRP limited to 36 dBm or 4W).
    • 3 to 1 dB rule for PtP.
    • European Standard EN 300 328 (EIRP limited to 20 dBm or 100mW), for unlicensed equipment.
  • 5.725-5.825 GHz (802.11a - Motorola [proprietary])
    • Licensed to both ISPs – ATLAS: Motorola Canopy & KOKONET:
    • Mainly used for backbone and last mile heavy users.
    • FCC rule 47CFR, Part 15.401-407 for ISP (EIRP limited to 53 dBm or 200W).
    • European Standard EN 300 440 (EIRP limited to 14 dBm or 25mW), for unlicensed equipment.
    • Telecom Division assists ISPs in their network planning to avoid interference.
  • 5.25-5.35 GHz
    • Reserved for Government usage.
    • Also a backup for fiber optic network.

ITU/ICTP Workshop

accomplishments
Accomplishments
  • Dedicated fixed broadband wireless access is very competitive ($100 per month).
  • Probably the only African country with national coverage (December 2000).
  • Have not experienced interference we have been unable to resolve.
  • Assisted in the widespread of Internet cafés.
  • Free fixed broadband wireless access to schools as part of USO.
  • It is a cost effective solution for VPN (for businesses) compared to lease line.
  • Assisted the Government to become more efficient (integration, delivery of e-Government, sharing of applications, files etc.).

ITU/ICTP Workshop

lessons learnt
Lessons Learnt
  • Regulation must be forward looking:
    • Allow deployment of new technologies.
    • Assist to prevent interference.
    • Assist to provide competition to Internet access (competitive rates).
  • Advise ISP on Freznel zone, cable loss and fade margin for long distance links. Special care for over water links (scattering).
  • Unable to use low portion spectrum of 2.4 GHz due to RUTEL system.
  • Good dialogue with all stakeholders are important to resolve interference problems.
  • Combo wireless equipment are useful if the customer needs to change service (low to high bandwidth) and flexibility (transition period).
  • Public education is imperative to avoid importation of non-compatible equipment (hence helps to resolve interference).

ITU/ICTP Workshop

future work
Future Work
  • Government plans to roll out 3.4-3.7 GHz (C extended band) wireless networks.
  • Analyze the experimental VOIP report on wireless networks.
  • Deploy encrypted/VPN wireless solutions for telemedecine project (Outlook and PGP) – 2nd opinion for X-ray images.
  • Ensure the rollout of hotspots at the airport, restaurants etc.
  • Experiment with low cost PtP USB/dish IEEE 802.11g wireless networks links.
  • Experiment with NetMeeting with freeware Gatekeeper and MCU (applications on fixed broadband wireless access).
