There won't be a fibre from those locations, they're only installed into locations that will have regular OBs. Unless the counts are at a sports ground or concert venue then there won't be any permanent connectivity. It's not worth installing anything temporarily for one night.

They won't install broadcast fibre, but they'll go for broadband installation as you certainly won't rely on any count centre infrastructure. In most cases it's public sector or an educational establishment. The ports you need will no doubt be blocked, and there's often no point trying to get them opened as IT policy will get in the way.

The cost of installing a 512mb line, full fibre, on a 12 month business contract (and the cost of paying a full year) is much less than a sat truck and sat time. Not to mention the fact trucks can be hard to get hold of on busy periods.

Know the right staff at the centre and you can use the network cabling in the venue to patch your way around to make life easier and less need for cable traps.

Throw on a decent network switch and you've enough connectivity for:
1x Live U feed up to 10Mbs but the same unit can also bring talkback and return vision
1x Ethernet for reporter's laptop
1x Ethernet for a Comrex / Luci Live for those centres also on radio.

You don't even need the most high-spec Live-U, just one with two sims as backup will do the trick and you've got redundancy.

Obviously if it's a big count, you'd look at an SNG, but even with the smaller installations, you can do multi-cameras with an ATEM switcher.

Some BBC Nations have been using that process for many years now.
