WCDMA and LTE synchronization
UMTS (Universal Mobile Telecommunication System) is one of the thirdgeneration
(3G) mobile systems being developed within the ITU’s IMT-2000
framework. Ordinary UMTS is implemented with WCDMA (Wideband Code
Division Multiple Access) technology and Frequency Division Duplexing
(FDD)
􀂃 The term WCDMA also refers to one of the ITU’s IMT-2000 standards, a
type of 3G cellular network.
􀂃 UMTS-TDD is a mobile standard built upon the UMTS 3G standard, using a
TD-CDMA, TD-SCDMA, or other 3GPP-approved, air interface that uses
Time Division Duplexing (TDD).
􀂃 HSPA (High Speed Packet Access) is a collection of mobile telephony
protocols that extend and improve the performance of WCDMA
􀂃 SAE, System Architecture Evolution is the core network architecture of
3GPP's future LTE wireless communication standard.
􀂃 LTE (Long Term Evolution) is the next major step in mobile radio
communications, and will be introduced in 3GPP Release 8 improving
latency, capacity and throughput.
