the problem physical
The problem - physical
  • Donegal – Ireland’s Switzerland!
  • Population 147,264
  • Dwellings and Businesses 91,414

the problem technical
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
The problems - financial
  • Density low in rural areas, not commercial using unlicensed radio
  • Even less possible using licensed
  • Urban(!) areas – cherry picked!

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
