GPRS or General Packet Radio Service is a GSM enhancement introduced in 2000 to facilitate packet-switched mobile data. GPRS is a 2G technology for the GSM mobile network evolution track; however, the network nodes it introduced are also used in 3G UMTS networks. Recent mobile networks, including 4G LTE and 5G New Radio (NR), are fully packet Global System for Mobile Communications (GSM, around 80–85% market share) and IS-95 (around 10–15% market share) were the two most prevalent 2G mobile communication technologies in 2007. [1] In 3G, the most prevalent technology was UMTS with CDMA-2000 in close contention.

The "G" in 1G, 2G, 3G, 4G, and 5G simply stands for "Generation". When we are connected to a telecommunication network, we can see the strength of the network signal. For example, we see 2G, 3G, or 4G right next to the signal strength bar on our respective home screens. Each of those indicating alphanumeric values defines the implementation of 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.
Frequency Division Duplex or FDD is a duplexing technique that employs separate frequency bands for uplink and downlink communication. FDD has been the most prevalent duplex technique in mobile communications, and the majority of 2G, 3G and 4G networks like GSM, UMTS and LTE have adopted it as their primary duplex scheme. In FDD communication
And the demand for 4G, 5G, LTE-M, and NB-IoT will only increase in the years to come. Most 2G networks based on GSM use 850–1800 MHz or 900–1900 MHz bands. And 3G networks use bands between 850–1900 MHz or 900–2100 MHz. More advanced cellular technologies could use these same bands to provide higher data throughput and more valuable The introduction of GSM into North America meant further adaptation to the 800 and 1900 MHz bands. Over the years, the versatility of GSM has resulted in the specifications being adapted to many more frequency bands to meet niche markets. A full list can be found in 3GPP TS 45.005.

2G (nebo 2-G) je zkratka pro 2. generaci bezdrátové telefonní technologie mobilního telefonu. GSM 2G je schopen přenášet data, SMS, digitální hlasový hovor, či ostatní základní pomocná data, jako např. datum a čas. Služby 2G byly v USA často uvedeny jako Personal Communications Service (PCS). Technologie 2G jsou rozděleny do

The lower 900MHz band was first introduced for early 2G GSM networks and several telcos have repurposed them for 3G and 4G use. Although it has less capacity compared to higher frequency bands, the 900MHz spectrum is still sought after as it provides wider coverage and it penetrates walls better.

Mai este cunoscut și sub denumirea de 2G (generația a 2-a). NMT aparține de 1G, iar UMTS și standardele similare aparțin de 3G. GSM 2G a apărut pe piață la începutul anilor 1990, luând un mare avânt la sfârșitul deceniului. Este sistemul dominant în Europa.
