Sonus and the Femtocell backhaul integration with core.

There are as many companies active on the femtocell backhaul integration with IP core as there are Femto cell manufacturers, with Kineto, Sonus and Tatara systems topping the list.

Sonus has recently announced partnerships with three femtocell manufacturers: ip.access, 3way and RadioFrame.

My worry is that some companies in the IP core space are re-inventing the wheel so to speak which threatens the main selling story for femtocells: the low introduction cost and the potential savings to operators. I'm no core expert, but I would guess that the existing framework(s) are sufficient to enable Femtocell integration with core networks without any major investment or development effort.
