While GSM 2G is still the backbone of voice and IoT services in some parts of world, and 4G is widely used for data services, 3G is fading out relatively faster. Considering market demands, Samsung is focusing its development efforts in the virtualization of 2G and 4G. Although 2G replaced 1G and is superseded by later technology versions, it's still used around the world. The maximum speed of 2G with General Packet Radio Service (GPRS) is 50 Kbps. The max theoretical speed is 384 Kbps with Enhanced Data Rates for GSM Evolution (EDGE) . EDGE+ can get up to 1.3 Mbps. 2.5G and 2.75G: Data, Finally 2G: Digital Voice. TDMA. 1990 cdmaOne: Qualcomm.

5G 2500 (41), 5G 39 (260), 5G 28 (260), 5G 600 (71) 2G, first introduced in 1992, is the second-generation of cellular telephone technology and the first to use digital encryption of conversations. 2G networks were the first to offer data services and SMS text messaging, but their data transfer rates are lower than those of their successors. 3G
GSM (ursprunglig akronym: groupe spécial mobile; numera Globalt system för mobil kommunikation ), är ett andra generationens (2G) mobiltelefonisystem, det vill säga ett digitalt system, framtaget av Internationella teleunionen. Det blev kommersialiserat 1991, [ 1] som har ersatt de analoga (d.v.s. första generationens
Abstract. The GSM standard developed by ETSI for 2G networks adopts the A5/1 stream cipher to protect the over-the-air privacy in cell phone and has become the de-facto global standard in mobile communications, though the emerging of subsequent 3G/4G standards. There are many cryptanalytic results available so far and the most notable ones
