Xiaobian to share with you what kind of network umts refers to, I hope you have something to gain after reading this article, let's discuss it together!

UMTS is the universal mobile communication system. As a complete 3G mobile communication technology standard, umts is not limited to defining the air interface. UMTS implementation is based on the widespread use of GSM mobile phone system, belonging to 2G technology.

UMTS presents:

UMTS(Universal Mobile Telecommunications System), UMTS as a complete 3G mobile communication technology standard, UMTS is not limited to defining the air interface.

In addition to WCDMA as the preferred air interface technology continues to improve, UMTS has also introduced TD-SCDMA and HSDPA technology.

A third generation (3G) mobile phone technology. It uses WCDMA as the underlying standard, finalized by 3GPP, and represents Europe's response to ITU IMT-2000 requirements for 3G cellular radio systems. UMTS is sometimes referred to as 3GSM, emphasizing that it incorporates 3G technology and is a successor to the GSM standard. UMTS packet switched systems evolved from GPRS systems, so the architecture of the systems is similar.

Features:

UMTS supports a transmission rate of 1920kbps (not the 2Mbps that is often seen), whereas the typical maximum rate in real-world high-load systems is only about 384Kbps. Even though the data speed is higher than GSM error correction data channel by 14.4 kbps or HSCSD channel composed of a plurality of 14.4 kbps, mobile WWW access and MMS can be realized at an acceptable price.

UMTS implementation is based on the widespread use of GSM mobile phone system, belonging to 2G technology. There is also an evolutionary path from 2G called GPRS. GPRS supports better data rates (theoretically up to 140.8kbps, actually close to 56kbps) and better data encapsulation than connection-oriented. GPRS is already deployed in many GSM networks.

China Unicom's UMTS network has been upgraded to HSDPA, sometimes called 3.5G. It can achieve downlink transmission speeds greater than 10Mbps.

UMTS has been marketed as emphasizing the possibility of mobile videoconferencing, although many of these promising services have yet to be tested.

Other possible applications for UMTS include music downloads and video telephony.
