[AusNOG] Femtocells

Having looked at this previously, I'd say it is a really useful way of
solving a number of issues, from the operator's point of view: local
coverage problems (let's face it, no matter how good your network is there
are always those building shadows and gullies that defy radio penetration),
base station saturation (more users/usage than a nodeB can withstand), and
backhaul capacity. In the latter case, the network operator even has the
benefit of the customer paying for the backhaul, so what's not to like about
that!

On the down side, the management of interference becomes more problematic,
but if the service provider can retain management capability on the
femtocell, then the output power should be adaptable to manage the cell
boundary issues. That does take time, and attention, and these things also
cost. I expect there are some automatic adaptation capabilities, but I
haven't looked at specific capability and effectiveness of it lately.

The other issue is with billing - if the operator runs both the consumer/SME
broadband service and the cellular service, that doesn't mean the two are on
the same billing or metering systems, and it will be very easy to double
count the usage. For voice, it can be mere 8kbps streams (compressed), but
there is talk now of high definition voice services being releases, and that
could easily be 1Mbps streams, either way, with the sort of plans I imagine
most people on this list have, it will be a drop in the bucket.

The catch, however, with suck it and see, is that one cannot configure one's
handset not to use the femtocell if you find the usage too much. But really,
voice calls are two tenths of a proverbial stuff all compared with data
usage.

QoS may or may not be enabled, either on your home broadband, and highly
unlikely to be across the network, but I can't really imagine it will be
much worse, if at all worse, than mobile services generally, even in areas
with great coverage.

One would expect that bundles on home internet plans will emerge, and either
discounting or metering changes will be integrated into the system then. The
link you gave below implies that already for the service provider in
question.
