    Well, I suppose had 3G been on a lower frequency i.e. 900Mhz or so, like GSM it might have actually been a way better technology. Instead, it was on a tiny allocation of frequencies stuck up at 2100MHz which resulted in really poor propagation of signals and it was never as good as it was promising to be.

    With 4G there are 800MHz and 900MHz allocations which may mean pretty excellent signal propagation characteristics and decent coverage in structures like trains and buildings etc.

    I think IE, and many others initially over-estimated how good a 3G UMTS 2100MHz USB dongle might be.

    WiFi's only really useful for short-range stuff, but it will remain handy for situations like this for as long as the mobile infrastructure can't penetrate car/coach bodies reliably.

    Also, the other reason is that some people switch off 3G while traveling as it eats batteries while WiFi has relatively little power consumption as it's a low-power local signal.

    Already is

    Thanks, I get the DART to work most days but hadn't seen any notices about it. Ill try it when I'm back to work after the Christmas & New Years break.

    Wifi shouldn't be advertised on southbound darts from Connolly or the Rosslare service as it is unusable.
    I have being using the USB WIFI stick on the Dart for a number of years, there has always been a few "black spots" with no signal. Between Blackrock and Salt hill, Dunlaoghaire and Sandycove (More so with the extension of the cut and cover) Dalkey and Killiney and of course Bray to Greystones. I am sure any WIFI transceiver would be the same.

    Well, it'll have the advantage of having a much higher gain antenna mounted on the train roof rather than a tiny little antenna on your USB stick. That's more likely to connect in areas of marginal coverage.

    An antenna on a train roof is still going to lose signal going through a blackspot, tunnel or cut and cover.

    Surely allocation of exact frequencies is down to the operators?

    Frequency allocation is set by Comreg, which the operators then bid on and use.

    Not only that, but the European operators all standardised 3G on UMTS-2100 (2100MHz) You can only really do what everyone else is doing as otherwise you won't have any handsets to use :)

    I think they've realised their error of their ways with 4G which is why we're seeing lower frequency allocations in the same kind of space that 2G occupies.

    Coverage from Heuston to Inchicore can be very poor at times in the 'Gullet'. Doesn't matter if using 3G or WiFi.

    I also find the service awful.

    Also hate having to login every single time I get on a train.

    this is a serious flaw - if you save the Irish_rail SSID on your phone, everytime you get on a train (and connect automatically) all your apps stop working until you fire up the browser and click through the welcome page. Stupid stupid stupid.

    You have to do the same with most free wifi and paid WiFi services. It's rare that you can connect automatically - eircom Hostspots are an exceptions if you're a customer. In logging on you are accepting the T&Cs. Do you really expect IE to make their system totally open?

    True - GoBus and Citylink services make you do this, and in the Ctylink case, it's the same provider (FleetConnect) as IE.

    been trying to use this from the city centre to Bray and 85% - 90% of the time it is unuseable.
    This is from either my phone or my tablet.
