Hi Harald,
SCF has a similar thing for 3G femtos, but its pretty much the same L1 implementation and not talking about the management of the femtos.
I actually looking into these units:
http://www.ebay.com/itm/AT-T-3G-MicroCell-signal-booster-DPH151-AT/161858135...
There is a lot of them, they are fairly cheap, I already know they run embedded linux (95% that its not VxWorks), and it is a Cisco product.
If you or nobody has any opposition (know something that makes this unit a near impossible candidate), I will probably buy one and take a look. It seems the successor of this product is also embedded linux, and it seems AT&T deploys them in huge quantities, so this seems to be a good candidate.
Regards, Csaba

Do you think that these vendor agnostic implementations can cahnge with the small cell forum API?
no.

This is the Layer 1 API between the PHY and the MAC/RLC layer. This is _very_ far from the Iuh interface. Compare it with the L1SAP interface of OsmoBTS. And Iuh is on th level of the A interface, not even Abis.
Also, this API is for LTE, not for UMTS.
Do we know any femtos on the market that actually is compatible with this API? And if we have one, can that help us?
You can find transceiver hardware + PHY implementations that offer this L1 API. However, that is not a complete (femto/small) cell, but the hardware plus the PHY.
I don't think anyone will quickly come about and implement all the missing layers, so in the context of developing a NITB with Iuh interface, it doesn't really help.
Or maybe you have some specific models in mind you always wanted to try but never had the time? If you have any recommendations I would be happy to look into them.
I haven't really looked at any femtocells for a very long time.
