Weired email from Orange

About a month ago I emailed Orange to ask about their transmitters working in powercuts (I was looking through their website) and I have just got this reply, which seems a little..well, contrary to what public information films have lead me to believe.

I think what may have happened is that your phone was talking to a mast in an area that wasn't suffering from the same power cut that you were.

I always thought they worked in a powecut

They do work during powercuts, I think they maybe solar power adaptable or use a back up supply by a special kind of generator. I know this because, they was a massive power failure covering South London,Surrey and parts of Kent. My mobile worked, payphones also work as they are not connected to any electrical supply although the kiosk lights will not work.

However, I doubt that pagers will recieve any reception since pager transmitters are a bit backward.

I have noticed when there is a large powercut covering an area as big as greater London, landlines sometimes fail.

Not all transmitters work in powercuts; my mate installs masts for a company that is subcontracted by all network operators; they recently installed a unit on the roof of our church hall - that would fail in a power cut as it draws power from the street mains supply and has no backup power supply.

I'm not sure what percentage of masts have backup supplies; I could ask my mate based upon his experience, though I suspect it's not that big a percentage.

Most power cuts tend to be very localised - if that affects the one your phone is talking to at the time, it'll probably just log onto a different one a bit further away, so your signal will appear to drop.
