UMTS - what is it?
Many have heard about the UMTS mobile communications standard, however, what exactly is meant by this abbreviation is not known to everyone. So, what is UMTS?
These four mysterious letters, like Universal Mobile Telecommunications, are deciphered. Translated into Russian, it sounds like a universal mobile telecommunications system. It was designed for the introduction of 3G in European countries. For data transfer, UMTS uses WCDMA technology, which theoretically allows for speeds up to 21 Mbps.
To date, the highest speed indicators are 7.2 Mbit / second for mobile stations HSDPA, and 384 Kbit / second for stations R99. The UMTS technology has become a significant leap when compared with the data transmission via GSM (9.6 - 14.4 Kbps).
Today, UMTS is widely used in many countries. Due to its high speed characteristics, it allows you to comfortably work with the World Wide Web services using a mobile phone or smartphone. UMTS technology provides high-speed downloading of multimedia content, and also allows you to work with video chat programs and mobile TV.
One of the main problems of the technology is increased power consumption. That is why many manufacturers of communicators and phones indicate different battery life in GSM and UMTS networks. Also, the standard is a relatively small coverage area. Today, in many countries, UMTS works correctly only in large cities and their suburbs.
