What type of network is umts?

umts is a 3G network type. UMTS refers to Universal Mobile Communications System, a 3G mobile communications technology standard, a third-generation (3G) mobile phone technology; UMTS is sometimes called 3GSM, emphasizing that it combines 3G technology and is a follow-up standard to the GSM standard.

The operating environment of this tutorial: OriginOS 3 system, vivo s15 mobile phone.

Mobile network modeUMTS refers to a 3G network standard. It is a 3G standard commonly used by mobile operators around the world, but in China China Unicom’s 3G network uses this standard. Neither China Telecom nor China Mobile's 3G networks use this standard.

umts introduction:

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

In addition to the continuous improvement of WCDMA as the preferred air interface technology, UMTS has also successively introduced TD-SCDMA and HSDPA technologies.

umts is a third generation (3G) mobile phone technology. It uses WCDMA as the underlying standard, finalized by 3GPP, and represents Europe's response to ITUIMT-2000's requirements for 3G cellular wireless systems. UMTS is sometimes called 3GSM, emphasizing that it combines 3G technology and is a follow-up standard to the GSM standard. The UMTS packet switching system evolved from the GPRS system, so the system architecture is quite similar.

Features:

UMTS supports a transmission rate of 1920kbps (not the often seen 2Mbps). However, the typical maximum rate in real high-load systems is only about 384Kbps. Even so, the data speed is already higher than the GSM error correction data channel of 14.4kbps or multiple HSCSD channels composed of 14.4 kbps, which can truly achieve affordable mobile WWW access and MMS.

The premise for the realization of UMTS is the widespread use of GSM mobile phone system, which belongs to 2G technology. There is also a way to evolve from 2G called GPRS. (Can be regarded as 2.5G) GPRS supports better data rates (theoretically up to 140.8kbps, in practice it can achieve close to 56Kbps), and data encapsulation is better than connection-oriented. GPRS has been 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 emphasizes the possibility of mobile video teleconferencing in its market operations, although in fact there are still many potential services that have not been tested and verified.

Other possible applications of UMTS include music downloading and video calling.

3G Technology

3G is the third generation of mobile communication technology, which refers to cellular mobile communication technology that supports high-speed data transmission. 3G service can transmit voice and data information simultaneously. 3G is a generation of mobile communication system that combines wireless communications with multimedia communications such as the Internet.

Compared with the first generation of mobile communication technology (i.e. 1G) and the second generation of digital mobile phone communication technology (i.e. 2G), 3G mobile phones mainly comprehensively integrate wireless communication and international Internet and other communication technologies. Form a new mobile communication system. This mobile technology can handle media forms such as images and music. In addition, it also includes some business functions such as teleconferencing. In order to support the above-mentioned functions, the wireless network can fully support different data transmission speeds, that is, whether it is indoors, outdoors, or in a driving environment, it can provide data transmission speeds of at least 2Mbps, 384kbps, and 144kbps. .

Third generation mobile communication technology (3G), 3G network technology is inevitable for the development of this field. 3G defines mobile communication technology standards, using higher frequency bands and CDMA technology to transmit data for related technical support. The working frequency band is high, and its main features are fast speed, high efficiency, stable signal, low cost and good security performance. Compared with the previous two generations of communication technology, the most obvious feature is that 3G network technology fully supports more diverse multimedia technologies.
