Depends where you live. I'm in an urban area and not that far from the
exchange, but several visits from Openreach later I can't get more than
3Mbps, which some would claim is also possible on 3G. They say I'd do
better on "Infinity", but I'm moving soon so probably don't qualify
under minimum contract periods.
There's quite a few rural parts of the country where 3G is better than
ADSL, to the point that there's no ADSL at all.
And the medium term problem with 4G is simply the total "spectrum"
available, and the way that leads to bandwidth caps and pricing issues.
4G might be a better sprinter, but I can't see it competing with wired
broadband for tens of GB a month.

What is sometimes called "4G" isn't really 4G anyway, it's 3GPP LTE,
which is only 3-and-a-bitG, we'll have to wait for at least LTE Advanced
before it meets the ITU definition of 4G.

They haven't done the spectrum auction yet - end of this year perhaps -
and full rollout won't start till 2014.

And not just in rural areas. And many rural areas also can't get
decent 3G coverage. Where I live ADSL, 2G and 3G are all poor.

(='.'=) Due to the amount of spam posted via googlegroups and
(")_(") their inaction to the problem. I am blocking some articles
posted from there. If you wish your postings to be seen by
everyone you will need use a different method of posting.
When the Gadget Show (yes, I know) demonstrated it, the speed achieved
using Speedtest was 89Mbps; more than twice the speed of Virgin's fibre
broadband.
This means I could burn through my bundled data allowance in under 6
seconds
In bursts, during quiet periods it will be quicker that ADSL [is now]. Even
now 3G in my phone (14M4bps, but un measured) can be quicker than my ADSL
(8Mbps). I would expect 4G to compete with 100Mbps broadband in the
pipeline (well duct anyway).
The important difference is that with wired you have your own wire to the
exchange or concentrator, so it is XMbps between you and the exchange, but
for wireless it is shared with lots of other users, so when it gets busy
your throughput will go sharply down.

Unfortunately, this theory only works if the exchange has massive
backhaul to the "core of the Internet". In practice, the backhaul from
individual exchanges will introduce significant contention (probably
between 20:1 to 50:1 for domestic customers) and then there's a second
level of contention between the ISP's central nodes and their
peers/transit suppliers.
All that's happening with mobile is the contention exists within the
spectrum between base and handset, as well as in the backhaul from the
base [and so on...].

The total capacity of a 3G base (with three sectors) is only 20Mbps. Any
one user is sharing 6Mbps with everyone else in his sector.

Why have the phone run at up to 14.4Mbps then?
In reality mine zips along (unmeasured) downloading stuff, but then I am
about 250m from a macro cell.

For 3.5G and 3.75G I suppose. (HSPA and HSPA+) But the point is that
this is somewhat like schoolboys peering at the speedo of a car and
deciding the highest number on the dial is how fast it could travel up
the motorway.

Distance shouldn't matter much, it's the number of people you are
sharing with, and whether the backhaul has been provisioned sufficiently
to support the site being used flat-out for data.
