What is the UMTS network?
UMTS means a universal mobile telecommunications system. The UMTS network is a 3G (third generation) wireless network that provides mobile and data service users with high bandwidth. 3G is the category of digital cellular radio systems developed according to the standard IMT-2000 (International Mobile Telecommunics-2000).
3G systems have been created with intent to allow users to have global mobility with services including the Internet, data, messages, paging and telephony. The intention was to provide consistent services to wandering mobile customers anywhere in the world. A combination of wireless services based on terrestrial and satellite broadcasts was designed for this availability.
The UMTS network is also called 3GSM (global mobile communication system) because it has evolved from this system. The air interface for the UMTS network is based on WCDMA (multiple access with multiple access) and includes HSPA (high -speed Access packets) specification. The Internet protocol wasBased on GPRS (General-Packet Radio Service), which developed in EDGE (increased data speed for global development, aka evolution), which were considered standards of 2.5G.
There are several ways of UMTS different from previous systems. One way is that previously cell systems were mainly switched by circuits, while UMTS is switched packets. It also has a higher bandwidth than previous systems.
Services provided by UMTS have three different quality services (QoS) target data speeds. These are 144 kbps (kilobytes per second) for the use of satellite and outdoor rural use; 384 kBP for use outdoors in the urban environment; and 2048 kbps for the use of indoor use and outdoor use that is low. There are four specified server classes. The conversational class includes voice services, video games and video calls. Class streaming includes multimedia, weboVé broadcast and video on request. The interactive class includes web browsing, accessing databases and network games, while the background class includes e -mail, download and SMS (short service message) messages.
LTE (long -term development) has evolved from UMTS. LTE and Wimax (worldwide interoperability for access to microwave) are two development of 4G wireless networks since 2010.
