Delivering Broadband in Rural Areas

John O’Raw – LYIT

Danny McFadden – Blue Box Broadband


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


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)

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


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


Where do people live?

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
