“The original scope of 3GPP (1998) was to produce Technical Specifications and Technical Reports for a 3G Mobile System based on evolved GSM core networks and the radio access technologies that they support (i.e., Universal Terrestrial Radio Access (UTRA) both Frequency Division Duplex (FDD) and Time Division Duplex (TDD) modes). The scope was subsequently amended to include the maintenance and development of the Technical Specifications and Technical Reports for evolved 3GPP technologies, beyond 3G.”
Telecoms & Internet converged Services & Protocols for Advanced Networks is a standardization body of ETSI, specializing in fixed networks and Internet convergence.
Universal Mobile Telecommunication System – 3G system.
Oriented towards generalized service diffusion, and future user trends: combines “cellular, “wireless”, “internet”, etc...
“multimedia everywhere”.
Developed in order to have an evolutionary path from 2.5G systems; progressive evolution (GPRS-EDGE-UMTS).
Flexible.
Handles multiple multimedia flows in a single connection.
Support to packet transport.
Flexible coding mechanisms (FDD/TDD WCDMA).
Variable transmission rates.
Max. 384 Kbps for global coverage (initially).
Max. 2Mbps for local coverage (initially)
uplink: 1920 – 1980 MHz (60 MHz).
downlink: 2110 – 2170 MHz (60 MHz).
