I-EDGE inguqulo esheshayo ye-GSM technology
Noma yikuphi ukuxoxisana ngeteknoloji yeselula kufakwe ama-acronyms. Kungenzeka ukuthi uke wezwa nge-GSM ne-CDMA, lezi zinhlobo ezimbili ezinkulu nezinhlobo zobuchwepheshe befoni yeselula. I-EDGE (Amanani Okuthuthukiswa Kwedatha ye-GSM Evolution) ukuthuthukiswa kwejubane nokuhamba kwesikhathi ku-GSM ubuchwepheshe. I-GSM, eqondene ne-Global System yezokuxhumana ze-Mobile, ibusa njenge-teknoloji yomakhalekhukhwini esetshenziswa kabanzi kakhulu emhlabeni. Isetshenziswa yi-AT & T ne-T-Mobile. Umncintiswano wayo, i-CDMA, isetshenziswa yi-Sprint, Virgin Mobile, ne-Verizon Wireless.
Ukuthuthukiswa kwe-EDGE
I-EDGE inguqulo esheshayo ye-GSM-ubuchwepheshe obuphezulu be- 3G eyakhelwe kumgangatho we-GSM. Ama-EDGE amanethiwekhi aklanyelwe ukuletha izinhlelo ze-multimedia ezifana nokusakaza ithelevishini, i-audio, nevidiyo kumafoni weselula ngokusheshisa kufika ku-384 Kbps. Nakuba i-EDGE ishesha ngokuphindwe kathathu njenge-GSM, ijubane layo lisafana nokuqhathaniswa ne-DSL ejwayelekile kanye nokufinyelela kwekhebula eliphezulu.
Izinga le-EDGE laqala ukuqaliswa e-United States ngonyaka ka-2003 ngu-Cingular, manje ose-AT & T, ngaphezulu kwezinga le-GSM. I-AT & T, T-Mobile ne-Rogers Wireless eCanada bonke basebenzisa amanethiwekhi e-EDGE.
Amanye amagama wobuchwepheshe be-EDGE afaka i-IMT Single Carrier (IMT-SC), i-GPRS Ethuthukisiwe (EGPRS) kanye namaThwalithi Okwaziswa Okuthuthukisiwe we-Global Evolution.
Ukusetshenziswa kwe-EDGE ne-Evolution
I-iPhone yasekuqaleni, eyaqala ngo-2007, yisibonelo esivamile sefoni ehambisana ne-EDGE. Kusukela ngaleso sikhathi, kuthuthukiswe inguqulo ethuthukisiwe ye-EDGE. Ukuguqulwa kwe-EDGE kungaphezu kokuphindwe kabili njengobuchwepheshe bokuqala be-EDGE.
