What generation is UMTS?
third-generation
UMTS (Universal Mobile Telecommunications Service) is a third-generation (3G) broadband, packet-based transmission of text, digitized voice, video, and multimedia at data rates up to 2 megabits per second (Mbps).
What are the main son components in UMTS?
UMTS specifies a complete network system, which includes the radio access network (UMTS Terrestrial Radio Access Network, or UTRAN), the core network (Mobile Application Part, or MAP) and the authentication of users via SIM (subscriber identity module) cards.
What is the architecture of UMTS?
UMTS system uses the same core network as the GPRS and uses entirely new radio interface. The new radio network in UMTS is called UTRAN (UMTS Terrestrial Radio Access Network) and is connected to the core network (CN) of GPRS via Iu interface.
What is the chipping rate of UMTS?
The chip rate for Cdma2000 and GSM are 1.2288 Mcps and 27.0833 Ksps respectively.
What does UMTS stand for?

Universal Mobile Telecommunications System (UMTS)
What is UMTS and GSM?
GSM is a second-generation (2G) technology, and UMTS is a third-generation (3G) technology. UMTS provides the 3G migration path to GSM and is therefore superior to GSM. When GSM networks were originally launched, they were circuit-switched and mainly offered voice and text message (SMS) services.
How does UMTS network work?
UMTS relies on a packet-switched system. This allows cellular devices to send small “packets” of data to a destination, whereas circuit-switched networks require a point-to-point connection. In an old phone network, making a call meant reserving a line between the sender and receiver.
What modulation is used in UMTS?
The basic signal format for UMTS is WCDMA, but this can utilise a variety of different forms of modulation. The modulation used for UMTS WCDMA is dependent upon a variety of factors including spectrum efficiency, signal to noise ratio, error correction and a number of other variable.
What is the chip rate of Wcdma?
3.84 Mchip/s
The basis for the physical layer of WCDMA is spreading of the data to be transmitted to the chip rate corresponding to 3.84 Mchip/s using channelization codes. It is also responsible for coding, transport-channel multiplexing, and modulation of the radio-frequency carrier.
