OK, this has come a little out of left-field. Sprint has launched a CDMA-based femto, manufactured by Samsung. I was expecting Sprint to push for WiMAX femtos when it launches (especially as 2.5GHz will have a hard time penetrating in-building), but I hadn't reckoned on them pursuing a similar approach for the mainstream CDMA cellular network.
Initially I though it might just be a repeater (widely used in Korea), but no, it's a proper broadband-connected femto. It was actually announced back in March & called UbiCell by Samsung - although at that point is wasn't obvious that it was so close to real, large-scale deployment rather than just going into operator testing like most of the UMTS/HSDPA ones.
One interesting feature is that it ships 'open' by default so any Sprint customer can use it - a sort of cellular FON model, I guess.
I'm guessing that RF management might be a bit easier in CDMA than UMTS.... but if anyone else has theories on how CDMA femtos have pulled out what I guess is a 18-24 month lead in largescale commercial shipments, I'd be fascinated to hear them.
