Airvana (who bought Cambridge, England based 3Way and are expected soon to IPO) are headquartered in Chelmsford, Massachusets, USA. They produce the HubBub femtocell, a 3G only device with variants for CDMA (EV-DO) and UMTS (HSPA) markets and provide the femtocell card inside a Thomson DSL/WiFi/3G home hub. The company also offers complete CDMA radio access networks for outdoor (macro) use, differentiated by only using IP architecture.

Their Universal Access Gateway offers to convert UMTS and CDMA into WiMax for long distance backhaul (similar to Samsung Ubicell). Its architecture includes both the femtocell (personal base station), UAG Security and Mobility Gateway, and Home Base Station Manager.

In September 2007, Airvana confirmed interoperability with Nokia Siemens Network femto gateway. Voice calls have already been made and further interoperability testing continues. Both boths can be sold independently.

January 2008, announced selection of Motive's HDM solution which uses the TR-069 standard for remote device management (HDM = Home Device Manager).

March 2008, announced a global OEM agreement with Motorola , who will resell their CDMA femtocells.

He predicts market demand of 400,000 units in the US (50% each CDMA and UMTS technology), growing quickly to millions of units in 2009.
