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.

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).

Sounds great ! So I can connect it to any operator provided that I have the required credentials.

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.

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.
