"Unlicensed Mobile Access (UMA) technology provides access to GSM and
GPRS mobile services over unlicensed spectrum technologies, including
Bluetooth and 802.11. By deploying UMA technology, service providers
can enable subscribers to roam and handover between cellular networks
and public and private unlicensed wireless networks using dual-mode
mobile handsets. With UMA, subscribers receive a consistent user
experience for their mobile voice and data services as they transition
between networks.
In order to promote the widespread adoption of UMA technology, a
number
of leading companies within the wireless industry have jointly
developed a set of open specifications. These specifications are
available through this Web site, and may be used by vendors and
carriers of wireless communications systems and applications to
develop
and deploy interoperable solutions.
In addition to developing and maintaining the initial specifications,
the participating companies are actively working with the 3GPP
standards organization to use the specifications as the basis for the
development of a formal standard."
UMA Participating Companies:
Alcatel
AT&T Wireless
British Telecom
Cingular
Ericsson
Kineto Wireless
Motorola
Nokia
Nortel Networks
O2
Rogers Wireless
Siemens
Sony Ericsson
T-Mobile US
