Real Wireless were there, as independent experts around small cells & related technology/strategy/economics of wireless.
Small cells were very prevalent and are definitely part of the mainstream.

* ALU announced a win with TIM Brazil - significant as LatAm market has been a bit wary.

The convergenve between WiFi (Hotspot 2.0, 11ac) and small cells. Meanwhile, there were lots of announcements on DAS (Comscope, Axell, TE), and ideas like Ericsson's Radio Dot which is sort of DAS/small cell hybrid. Meanwhile there are several different perspectives on cloud-RAN.
