  3. Background ITU/ICTP Workshop

  4. 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. ITU/ICTP Workshop

  5. 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

  6. 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

  7. 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

  8. 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).
