What is meant by UMTS?

UMTS or the Universal Mobile Telecommunications System is a third generation wireless network technology which allows speeds of up to 2Mbps. UMTS is based on the WCDMA technology, which is why these terms have become interchangeable.

What is UMTS HSPA?

UMTS provides a clear evolutionary path to high-speed packet access (HSPA). HSPA refers to the combination of high-speed downlink packet access (HSDPA) and high-speed uplink packet access (HSUPA). HSPA also boosts capacity in UMTS networks and provides significant latency reductions.

What is the architecture of 4G?

Named as LTE « Long term evolution », the 4G system architecture is made up of an EPC (Evolved Packet Core) and Evolved Universal Terrestrial Radio Access Network (E-UTRAN). This paper provides an overview of the 3GPP releases relevant to 4G.

What is the main features of UMTS architecture?

The UMTS network architecture is partly based on existing 2G network components and some new 3G network components. It inherits the basic functional elements from the GSM architecture on the core network (CN) side. The CN provides circuit switched (CS) functions as well as packet switched (PS) functions.

What is the purpose of UMTS?

UMTS (Universal Mobile Telecommunications System) is a so-called “third-generation (3G),” Broadband , packet -based transmission of text, digitized voice, video, and multimedia at data rates up to and possibly higher than 2 megabits per second ( Mbps ), offering a consistent set of services to mobile computer and phone …

Which is faster UMTS or HSPA?

UMTS can offer peak download speed of up to 2 Mbps and average download speed of 384 kbps. HSPA can offer peak download speed of up to 14.4 Mbps and average download speed of around 5 Mbps. HSPA+ can offer peak download speed of up to 42 Mbps and average download speed of 5-8 Mbps.

What do you call UMTS terrestrial radio access?

The air interfaces are called UMTS Terrestrial Radio Access (UTRA). All air interface options are part of ITU ‘s IMT-2000. In the currently most popular variant for cellular mobile telephones, W-CDMA (IMT Direct Spread) is used. It is also called “Uu interface”, as it links User Equipment to the UMTS Terrestrial Radio Access Network

Which is an external interface in the UMTS network?

The Iu interface is an external interface that connects the RNC to the Core Network (CN). The Uu is also external, connecting the Node B with the User Equipment (UE). The Iub is an internal interface connecting the RNC with the Node B. And at last there is the Iur interface which is an internal interface most…

Where is the UTRAN located on the UMTS network?

The UTRAN allows connectivity between the UE (user equipment) and the core network . The RNC provides control functionalities for one or more Node Bs. A Node B and an RNC can be the same device, although typical implementations have a separate RNC located in a central office serving multiple Node Bs.

Which is the most common member of the UMTS family?

W-CDMA is the basis of Japan’s NTT DoCoMo ‘s FOMA service and the most-commonly used member of the Universal Mobile Telecommunications System (UMTS) family and sometimes used as a synonym for UMTS.
