What is MMDS?

    There were a few MMDS fed small cable systems using DVB-T where Chorus had cheaped-out and failed to install a fibre feed to an isolated cable system and just whacked up an MMDS antenna instead.

    All of the 'proper' cable systems including all the ex-Chorus ones, use DVB-C. So, you're not very likely to come across this system other than in a few small towns or isolated housing estates in the countryside.

    Also, if those MMDS fed cable systems are plugged into a proper UPC cable head-end, the cable system would have the bandwidth to organise a temporary simulcast until the boxes were swapped.

    There's absolutely no possibility of doing this with MMDS on air as there simply is not enough bandwidth.

    Remember, that Chorus used DVB-C cable boxes made by Sagem in Cork and elsewhere, these are 100% compatible with UPC cable. They physically look like the Sagem DVB-T MMDS boxes, but they are not using the same technology.

    The ex-Chorus cable network already is DVB-C. It's the MMDS network that is DVB-T.
    That's incorrect in some cases. E.g. in the likes of parts of Trim I believe.

    Also my post was a query about

    Dvr's were rolled out on the DVB-T system in Killarney
    I thought that a place like Killarney would have had some sort of cable network already. So I wanted to confirm if that was a DVR trial for purely MMDS customers or if there was a small cable system that used DVB-T (picked up from another MMDS site)
