Useful links to UMTS / IMT-2000 resources.
||Universal mobile telephony system (UMTS) refers to the next
generation of cellular technology that is also being standardized by
European Telecommunications Standard Institute (ETSI).
Wideband code division multiple access (WCDMA) is the air
interface technology selected by ETSI and the major European and
Japanese mobile communications operators. This technology is
optimized to allow very high-speed multimedia services such as
full-motion video, Internet access, and videoconferencing.
Spectrum for UMTS WRC’92 identified the frequency bands
1885-2025 MHz and 2110-2200 MHz for future IMT-2000 systems, with
the bands 1980-2010 MHz and 2170-2200 MHz intended for the satellite
part of these future systems.
Circuit and Packet Domains Two types of networks
approaches are specified for UMTS - the R99 core network solution:
circuit and packet domains. Iu-cs is an UMTS interface for the
circuit domain, equivalent to the GSM "A" interface, Iu-ps
is an UMTS interface for packet domain, equivalent to the
"Gb" interface in GPRS.

The UWCC (Universal Wireless Communications Consortium) is a
consortium of over 100 telecommunications carriers and vendors of
wireless products and services. The consortium is dedicated to support
TDMA, a digital wireless air interface complemented by the Wireless
Intelligent Network (ANSI-41). The UWCC is a limited liability company
formed in Washington State in 1996.

EDGE is referred to as 136HS in the UWC standard. It has both a wide
area and an indoor component to provide data rates of 384 kbps and 2
3rd Generation Partnership Project (3GPP)
IMT-2000 is the International Telecommunication Union’s (ITU)
framework for third-generation standards. Technical specifications for
IMT-2000 members are being developed by the 3rd Generation
Partnership Project (3GPP), a global
co-operation between six Organisational Partners (ARIB,
Market Representation Partners
A Market Representation Partner (MRP) is any organisation that has
been invited by the Organisational Partners to take part in 3GPP,
irrespective of geographical location, and who are able to bring
pertinent competencies including the ability to offer advice to 3GPP and
to bring a consensus view of market requirements falling within the 3GPP
Where Does WAP fit in?
WAP brings Internet content and advanced services to digital cellular
phones and other wireless terminals. WAP is a global wireless protocol
specification that works across the following wireless network
technology types: GSM (900, 1800 & 1900MHz),
PDC, CDMA (IS-95 and/or IS-707), US-TDMA
(IS-136), iDEN (ESMR), DataTAC, Mobitex, CDPD, DECT, PHS, FLEX, and
ReFLEX. Applications using WAP are scaleable across a variety of
transport options and device types. A common standard offers potential
economies of scale, encouraging cellular phone and other device
manufacturers to invest in developing compatible products. With WAP,
cellular and other wireless network carriers and content providers are
able to develop new differentiated service offerings as a way to attract
new subscribers, while consumers benefit from more and varied choices in
mobile communications applications, advanced services and Internet
