On April 2, 2024, T-Mobile’s older 2G GSM network will be retired As of July 1, 2022, T-Mobile’s older 3G UMTS network has been retired As of June 30, 2022, Sprint’s LTE network has been retired
GEA/1 and GEA/2: Rather insecure encryption algorithms covering the entire GSM/GPRS/ EDGE/3G/4G spectrum, which can be easily decrypted. GEA/3 and GEA/4: Similar to the A5/3 and A5/4, the GEA/3 is based on the 64-bit version of KASUMI, while the GEA/5 offers the advanced 128-bit version. Both cover the full cellular spectrum GSM/GPRS/EDGE/3G/4G.
T-Mobile also plans to shut down its 3G networks by July 1, 2022, and will retire its older GSM 2G network, but no date has been set. Verizon said it would finish decommissioning its 3G network by Second Generation (2G) technology was launched in the year 1991 in Finland. It is based on the technology known as global system for mobile communication or in short we can say GSM. This technology enabled various networks to provide services like text messages, picture messages and MMS. In this technology all text messages are digitally… Additional spectrum would require more investments which operators are presently unable or unwilling to make. Another factor is the plurality of different systems in the region (i.e., TDMA, GSM and CDMA), which complicates the migration path from 2G to 3G.

The 2G technology was nowhere near up to the job, so the industry began to work on the next generation of technology known as 3G. The main technological difference that distinguishes 3G technology from 2G technology is the use of packet switching rather than circuit switching for data transmission. [48]
GPRS and EDGE are both 2G technology, but EDGE is significantly faster with a download speed of up to 384Kbps. EDGE is most-a-times called a 2.5G network as it also has some characteristics of a 3G network, but it doesn’t satisfy the specification. 3G. Introduction of the 3G network made video calling and seamless streaming of video possible. The speed increases and the technology used to achieve that speed also changes. For eg, 1G offers 2.4 kbps, 2G offers 64 Kbps and is based on GSM, 3G offers 144 kbps-2 mbps whereas 4G offers 100 Mbps - 1 Gbps and is based on LTE technology . The aim of wireless communication is to provide high quality, reliable communication just like wired 3G (2000) – the third generation standard. 3G was introduced by the operators to deal with the increasing demand for data by consumers. People wanted to browse the internet on their phones and even watch video. 3G initially offered speeds of 500Kbps to 2Mbps, but over the years through enhancements like HSPA ()High Speed Packet Access), 3G is 3G Spectrum Cost Telcom 2720 18 UMTS • ETSI proposed GSM/NA-TDMA /GPRS evolution under name Universal Mobile Telecom.

4G vs 3G speeds. One of the principal differences between 3G and 4G models is the speed at which they can download files from the internet. A typical 3G connection has a maximum speed of up to
GSM 850, GSM 900, GSM 1800, GSM 1900: 3G capabilities: 5G capabilities . 2G, first introduced in 1992, is the second-generation of cellular telephone technology and the first to use digital

All operators have agreed with the government to switch off 2G and 3G by 2033. *Three UK never had a 2G network as it launched as the UK's first 100% 3G network. Virtual networks (otherwise known as Mobile Virtual Network Operators), such as Giffgaff, Tesco Mobile and Smarty, operate off the main four mobile network operators.

UMTS is the 3G migration path used by the most widely deployed second-generation (2G) technology, GSM. UMTS (Universal Mobile Telecommunication System) is a third-generation cellular technology that allows 2G GSM networks to migrate to 3G. UMTS employs Wideband CDMA (WCDMA) for its radio interface to enable peak download data rates of up to 2 NN8wJUb.
