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,[1] 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.Template:Dubious

Pamanalkus papuntang 4G[mag-edit | edit source]

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.[2]
