Wireless. "As the technology behind successful dual-
mode handset services, such as Unik from FT/Orange and
T-Mobile's Hotspot @Home, the 3GPP UMA standard has
already identified and addressed the real-world deployment
These issues include security, device authentication,
access controls, handover, regulatory compliance, as well
as scalability to support millions of endpoints."

integration standard.

scalable procedure is required to be in place to enable a
femtocell to power on and begin delivering services with
minimal network provisioning overhead. Upon femtocell
powering, a procedure must be defined for the femtocell
to identify its relative global location, determine the
appropriate RAN Gateway to which it should associate,
determine if the femtocell is allowed to offer service in its
current location, as well as register the femtocell with the
RAN Gateway in order to begin offering local coverage.
