3G

Ing International Mobile Telecommunications-2000 (IMT-2000), mas balu ra keng aus a 3G o ikatlung Generasiun, meutng yang famila a iley o batayan (standards) para kareng mobile telecommunications a lalarawan ning International Telecommunication Union, nung nu kayabe la reng GSM EDGE, UMTS, ampong CDMA2000 at makanyan mu rin deng DECT ampong WiMAX. Ding kayang susuyuan kayabe la reng wide-area wireless a siuala telepanu, aud pangvideo, ampong alangkuryenting data, lat(eganagana) king maski nokarin a likas (mobile environment). Nung kumpara keng 2G ampong 2.5G a suyu, Ing 3G papabustan na ing agnanagnan a pamanyalita ampong suyu keng data ampong mas matas a pulayi keng data (anggang 14.0 Mbit/s keng downlink ampong 5.8 Mbit/s keng uplink kambe ning HSPA+). Inya, deng gagamit keng 3G networks, dirinan no reng network operators mas maleparan a gamit ampong mas matas a suyu kabang akakua ra ing mas dakal a capacidad kapamilatan ning masmasanting a spectral efficiency.

Ing International Telecommunication Union (ITU) pemamasala na na ing pangatlung generasiun (3G) da ring apidaladalang telepanung iley (mobile telephony standards) – IMT-2000 – ing apabilis ing pamanadagul, irakal ing bandwidth, ampong sopan la reng masa dakal a mialiwang klasing gamitin (applications). Alimbawa, ing GSM (ing kasalungsungan pekabantug a cellular phone standard) malyari yang magdalang emu siuala, dapot ita mu rin circuit-switched data a atin download a pulayi a 14.4 kbps. Dapot para a supportan ing mobile multimedia applications, ing 3G dapat yang magdalang packet-switched data masmasanting a spectral efficiency, king mas dakal bandwidths.

Pamanalkus papuntang 4G 
Both 3GPP and 3GPP2 are currently working on further extensions to 3G standards, named Long Term Evolution and Ultra Mobile Broadband, respectively. Being based on an all-IP network infrastructure and using advanced wireless technologies such as MIMO, these specifications already display features characteristic for IMT-Advanced (4G), the successor of 3G. However, falling short of the bandwidth requirements for 4G (which is 1 Gbit/s for stationary and 100 Mbit/s for mobile operation), these standards are classified as 3.9G or Pre-4G.

3GPP plans to meet the 4G goals with LTE Advanced, whereas Qualcomm has halted development of UMB in favour of the LTE family.
