What is 3G UMTS?

The third generation (3G) Universal Mobile Telecommunication System (UMTS) is one of two competing 3G technologies used in mobile phones. The 3G UMTS standard can allow faster data speed than previous 2G systems. In addition, UMTS contains specifications for the entire 3G voice and data network. 3G UMTS is closely related to older technologies, such as increased data speed for GSM (EDGE) evolution and global mobile communication system (GSM). Some UMTS phones can use one or both of these slower protocols unless the network is 3G unavailable.

The UMTS standard is used worldwide, although the actual name UMTS is most commonly used in Europe. In the US, 3G UMTS is usually sold simply as 3G. Although 3G UMTS builds on many concepts used in EDGE and GSM, UMT cannot be operated in parallel at the same frequencies as these standards. UMTS also requires a brand new hardware to be installed in the cells of the carrier. So while Edge can be operated by parallelThe GSM can be a relatively expensive upgrade. Some carriers may decide to use EDGE as a stopgap measure before creating a full UMTS network.

The

3G UMTS networks are often charged as a broadband connection. Although the actual download and recording speeds can be slower than traditional broadband connections, they can often represent a significant improvement in 2G data systems. EDGE can also offer increased speed compared to the older GSM system, but UMTS can increase potential speeds to low-end broadband. Reserved 3G UMTS modems are usually available for computers and provide broadband on the road. Similarly, some carriers can allow users to log in their UMTS phones to your computer. This process of tethering can also provide a broadband connection where broadband would otherwise be available.

the mainThe competitive 3G protocol is known as the Mult Division of Codeiple Access (CDMA2000). This technology is used by a number of carriers in the US, although in most other countries it is not so widespread. While UMTS is part of the third -generation partnership project (3GPP), the CDMA2000 belongs to the competitive partnership project of the third generation 2 (3GPP2). Direct development of the Provisional Standard 95 (IS-95) 2G may coexist CDMA2000 at the same frequencies as this older technology. It is a similar relationship between 3GPP GSM and EDGE technologies, although CDMA2000 is fully 3G. Due to this interoperability, the assembly costs for CDMA2000 networks may be cheaper compared to UMTS networks. Unlike UMTS, CDMA 2000 does not have a natural successor. Long -term development (LTE), standard 3GPP, is the only successor of both competing 3G technologies.
