  1. Delivering Broadband in Rural Areas John O’Raw – LYIT Danny McFadden – Blue Box Broadband

  2. We will cover......... • The problem (physical) • The problem (technical) • The problem (financial) • Last Mile solutions • 2.4ghz unlicensed (unusable) • 5ghz unlicensed (residential) • 3.5ghz licensed (business) • Backhaul solutions • Licensed microwave with MPLS • Unlicensed

  3. The problem - physical • Donegal – Ireland’s Switzerland! • Population 147,264 • Dwellings and Businesses 91,414 • Land area 4,830 km2 • Only 30 persons/km2 • 15 urban(!) areas (population>2,000) Source: Census 2006/GeoDirectory

  4. The problem - technical • Deliver residential broadband • 54mbs into (maximum) 62 clients per base station • Deliver business broadband • Up to 54mbs PTP basic service unlicensed • Deliver PTP layer 2 circuits at fibre quality licensed • Deliver layer 3 circuits at fibre quality licensed • Deliver services at up to 1gbs And then.......... • Double Play – add on voice • Triple Play – add on digital/mobile TV

  5. The problems - financial • Density low in rural areas, not commercial using unlicensed radio • Even less possible using licensed • Urban(!) areas – cherry picked! • The market has not provided! • No economic public infrastructure • Even small costs make model uneconomic • Fast time-to-market • Low TCO

  6. Where do people live? Source: Geodirectory/SRTM

  7. The solution - technical • Create a ring of licensed microwave sites • Make even the most remote location one unlicensed hop from the ring • Use MPLS to ensure carrier grade services • Use 5.8ghz/layer 3 unlicensed for residential • Use 3.5ghz/layer 2 licensed for business • User other licensed for larger business

  9. Link Budget Planning

  10. Ring Site Topology Licensed Microwave Licensed Microwave MPLS Router Major Customer 3 Sector Site WISP Router 3 Sector Site 5.8 Ghz Unlicensed Link

  11. Coverage Around Buncrana Buncrana Rathmullan Source: SRTM/NWEWN/Radio Mobile

  12. Typical Capability • Around.... • 24mbs up to 9kms • 18mbs up to 12kms • 14mbs up to 17kms • 12mbs up to 24kms • 3mbs up to 45kms • Theoretically possible to run a service up to 60kms

  13. Current Projects • NWEWN • Establish a carrier grade MPLS network • WISP TacaTeo. • Service model for WISPs • Bespoke database and web applications with GIS • “Anywhere” service desk • Undisclosed • Provision of student services to accommodation • Undisclosed • Financial Services / remote services • MSc Thesis • Predictive diagnostic analysis on WiMAX links
