    Convince WiKi and you'll convince me...

    In my experience eircom has been the most reliable, use it for voip ever day and have not dropped a call in a year, happy with the service, just wish they'd unbundle the fixed line I don't use and pass me on the discount. BT were also relaible be alas are no more..:(

    I certainly hope that there is mobile broadband seen as though I have been working on umts systems for the last 5 years. For mobile broadband the btses have to be upgraded to node-bs. 3g or umts is commonly known as mobile broadband

    Well you and the people in the Mobile Phone industry can call it Mobile Broadband. But it doesn't meet the internationally agreed specs for Broadband nor the specs laid down by our own Government in 2004

    * Broadband is Always on. Mobile attempts to connect on demand and may not.
    * Broadband is 0.512, 0.768, 1.5Mbps minimum depending on country. Mobile can easily be 0.05kbps and on a loaded sector with 10 simultaneous connections is < 250Kbps
    * Broadband is low latency, typically less than 50ms, Cable < 20ms and rarely ever more than 70ms. Mobile is 100ms to 2000ms, typically 170ms
    * Contention is strictly controlled on Broadband. Mobile can only control contention by refusing new connections.
    * Broadband works irrespective and unaffected by voice Traffic. Mobile shares bandwith with voice traffic which has priority and subsidises data by 100:1 to 500:1
    * The OECD does not count Mobile as Broadband.
    * The FCC does not count Mobile as Broadband.

    Why Mobile is not Broadband and is typically 16x worse than Fixed Wireless in Same Spectrum
    http://www.techtir.ie/forums/showthread.php?t=1832

    This is not such an issue in other countries because they have decent broadband infrastructure.

    Mobile Internet is a VERY valuable service made up to FIVE times poorer in Ireland by the amount that is sold to Fixed users. If you are "on the go" you need mobile. If you are Fixed you should have real Broadband.

    You can work on UMTS node-B as much as you like and polish it to 21Mbps. Even then to make much difference compared with 3.6Mbps we would x6 the density of cells!
    See http://www.theregister.co.uk/2009/12/29/o2_apology/

    UMTS / HSPA can provide Mobile Internet. It's not Broadband.

    Even LTE, if implemented in FOUR times the spectrum UMTS/3G/HSPA is using today, will only just manage entry level DSL performance, and only if very lightly loaded, at peak times it would be 5 times poorer. Entry level DSL (1Mbps down /128k up) is no longer regarded as valid target for Broadband rollouts. Targets now are 2Mbps rural and 10Mbps Urban, LTE can't do that. Its 100Mbps is peak speed in <1% of cell area with one connection only.

    UPC is rolling out 120Mbps in 2010 (almost this year now) .

    I've been on 8Mbps down /1Mbps up 25ms "always connected" Fixed Wireless since 2005. That's more than twice the national DSL average and x10 typical off peak 3G speed and 6x better latency than typical 3G/HSPA. Unlike Mobile it has its own IP and is always connected. In European terms today it would be less than entry level for new rollouts.

    Even in UK which is fairly backward in European terms maybe 40% may have FTTC >20Mbps before the London Olympics.

    In the real world outside of the Mobile Phone companies most Europeans expect more speed and performance on their Broadband than Irish node-B have as backhaul for entire mast!

    Would you like to tell me how many sites have 100Mbps or better and how many are fed by DSL and how many use E1 (2.048Mbps ISDN)?
