There are a large number of variables, which give advantages
and disadvantages to either

Google groups archives have covered this subject often

No, most models think building penetration losses either don't change
with frequency or, in fact, decrease a bit with increasing frequency.
The issue of in-building coverage is mostly dominated by how much
signal you have outside the building before the penetration loss
occurs, and 900 MHz networks will often have more of that.

If there's a downside to 900 MHz (outside of really dense city
cores) it is that 1800 MHz GSM and 2100 MHz UMTS can usually
share antennas (the panels are usually 1700-2200 MHz) and cell
spacing while 900 MHz GSM and 2100 MHz UMTS need separate antennas
and 3G probably needs more cells, so adding 3G service to an existing
1800 MHz network is usually cheaper. I'd guess this is why Vodafone
and (particularly) O2 seem to have sparser 3G coverage.

Maybe not the building itself, but they contain entrance, ventilation
and window openings, which tend to offer more scope to higher
frequencies than lower.
and you can't assume that there will be more signal at lower frequencies
entering the building, in fact as there are more 1800, and 2.1g BTS,
the odds are any building will be closer to one of those than a 900MHz one,
and even a higher frequency BTS further away may get the advantage
of a better reflective path as higher frequencies reflect better off of
conductive surfaces

That's under normal atmospheric conditions, if there's a tropospheric
or temperature inversion lift on, frequencies affected start from high
to low

The number of variables involved are enormous

Thanks for the responses everyone.

My son has an O2 contract (still in my name) and I called up to query 2
things:
1 was to see if Conference Calling was available to which they said no - is
this correct??
2 was to increase his tariff to include more minutes. Instead of being
helpful they were rude and said that I couldn't have Unlimited O2-O2 calls
and the Web bolt on free (both were added free by retentions on the last
upgrade). The person demanded I picked one to remove there and then. In
the end I spoke to a supervisor who said I could keep the 2 bolt-ons. Bad
experience there.

Anyway, this put me off O2 and I now have an Orange business contract with 8
phones. So far things have been pretty good. Answer Fax is a great little
feature for us and Conference Calling etc. work, unlike on O2.

The only thing I've been irritated at was that when in Ireland last week the
Meteor network was unavailable, despite being listed as having a roaming
agreement on the Orange website. Maybe Orange cutting down on costs
there...hmm. Apart from that everything's been great - happy Orange
customer :)
