The Universal Mobile Telecommunications System (UMTS) is a third generation mobile cellular system for networks based on the GSM standard. Developed and maintained by the 3GPP, UMTS is a component of the International Telecommunication Union IMT-2000 standard set and compares with the CDMA2000 standard set for networks based on the competing cdmaOne technology. UMTS uses wideband code-division multiple access (W-CDMA) radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators.
T-Mobile is the brand name used by some of the mobile communications subsidiaries of the German telecommunications company Deutsche Telekom AG in the Czech Republic, Poland and the United States.

In telecommunications, long-term evolution (LTE) is a standard for wireless broadband communication for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. It improves on those standards' capacity and speed by using a different radio interface and core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. Because LTE frequencies and bands differ from country to country, only multi-band phones can use LTE in all countries where it is supported.
The XT Network was a brand name for a UMTS and LTE mobile network run by Spark New Zealand . The network was initially built nationwide on WCDMA/UMTS 850 MHz, with 2100 MHz infill in major urban areas. The UMTS network is HSPA+ enabled, with a maximum downlink transmission rate of 21.1 Mbit/s and an uplink rate of 5.2 Mbit/s attainable for capable hardware. HSPA+ has a theoretical maximum of 56 Mbit/s download speed and 22 Mbit/s upload speed. Then under Spark 4G LTE is being built out. The network is not 2G capable, Telecom never operated a public GSM network.

In telecommunications, 4G is the fourth generation of cell phone mobile communications standards. It is a successor to the third generation (3G) standards. A 4G system provides mobile "ultra-broadband" Internet access. Major Australian telecommunications companies, and most resellers that use one of these major telcos, have been rolling out and continuing to upgrade 4G since 2011/2012.
3G mobile telephony was relatively slow to be adopted globally. In some instances, 3G networks do not use the same radio frequencies as 2G so mobile operators must build entirely new networks and license entirely new frequencies, especially so to achieve high data transmission rates. Other delays were due to the expenses of upgrading transmission hardware, especially for UMTS, whose deployment required the replacement of most broadcast towers. Due to these issues and difficulties with deployment, many carriers delayed acquisition of these updated capabilities.
Airtel India commonly known as Airtel, is the second largest provider of mobile telephony and third largest provider of fixed telephony in India, and is also a provider of broadband and subscription television services.
