Hi,
Can a UMTS network be implemented using what is already available from OSMO projects ?

Yes, see http://osmocom.org/news/59 (about one year ago) and http://osmocom.org/news/67
However, you need a [proprietary] femtocell, small cell or classic
NodeB+RNC which can provide either an Iuh or an Iu interface over IP to
the Osmocom stack. So it's basically at the stage where we were with
GSM in 2008-2010 and you needed a proprietary BTS and we had everything
from the BSC upwards in Osmocom.
Regards,
Harald

Hi,
I don’t know much about femtocells, where can I get one and does it connect to any 3G
operator ?

sysmocom is selling femtocells both individually as well as part of the
"sysmoNITB 3G5 Starter Kit".
Please note that there is nothing sysmocom-specific in the Osmo-Iuh
code, you should be able to use any device that exposes its Iuh or
IuCS/IuPS over IP.

No, a femtocell sold to an end-user/consumer will typically only connect
to the one operator to which it was provisioned to connect. The
femtocell and small-cell devices shipped by sysmocom are special in that
regard, as they are sold to you as the operator of your network. This
means that you can configure where it shall connect, and what kind of
authentication/credentials to use (if any).
Still, you will only be able to connect those femtocells to a core
network that you control (Such as one based on an installation of the
Osmocom components), as you will not have credentials to authenticate to
an operator that is not under your control (such as regular commercial
cellular operators like Vodafone or T-Mobile).

Does this mean that if I have a femtocell that is connected to an operator that I
control, then I must manually tell my phone to connect to the femtocell ? How will the
phone be able to differentiate between the original operator and the femtocell if both
share the same signature ?

Not neccessarily. Depends on your detailed configuration.

operator and the femtocell if both share the same signature ?
Normally you would insert the SIM Card of your own operator when running
phones on your own network. Just like normal operators out there,
nothing special. Normal cell/network selection procedures of phones
apply.
