Isingeniso ku-1G, 2G, 3G, 4G & 5G Engenantambo
Isithwali sezintambo singase sisekele i-4G noma i-3G kuyilapho amanye amafoni akhiwa ngenye yezo. Indawo yakho ingavumela kuphela ifoni yakho ithole isivinini esingu-2G, noma ungabona igama elithi 5G liphonswa nxazonke lapho likhuluma nge-Smartphones.
Njengoba i-1G isungulwe ekuqaleni kwawo-1980, kuye kwakhishwa iteknoloji entsha yokuxhumana yocingo engenazintambo cishe njalo eminyakeni eyishumi. Zonke zibhekisela kwezobuchwepheshe ezisetshenziselwa umphathi weselula kanye nedivayisi ngokwayo; banezivinini nezici ezahlukene ezithuthukisa isizukulwane ngaphambi kwayo.
Ngesikhathi i-acronym ngezinye izikhathi i-techno ibonisa ukuthi umenzi wesidingo akudingeki ukuthi afunde kahle, abanye kubalulekile ekuqondeni kwansuku zonke. Ungase ufune ukwazi ukuthi lobu buchwepheshe buhluke kanjani nokuthi busebenza kanjani kuwe uma uthenga ifoni, ukuthola imininingwane yokubika, noma ukubhalisela umphathi weselula.
I-1G: Izwi kuphela
Khumbula i-analog "amafenki ezitini" nethi "amafoni weselula" indlela, emuva emuva emini? Amafoni aqala ngo-1G ngawo-1980.
I-1G iyinhlangano yobuchwepheshe be-analog futhi amafoni ngokuvamile abe nempilo ebhethri empofu nekhwalithi yezwi yayinkulu ngaphandle kokuvikeleka okuningi, futhi ngezinye izikhathi ukuhlangenwe nakho kwehlisa izingcingo.
Ijubane elikhulu le-1G lingu-2.4 Kbps . Okuningi "
I-2G: i-SMS ne-MMS
Amafoni athola ukuthuthukiswa kwawo okuqala lapho ehamba esuka ku-1G kuya ku-2G. Lokhu kuqubuka kwenzeke ngo-1991 kuma- GSM amanethiwekhi kuqala, eFinland, futhi ngokuphumelelayo wathatha amafoni kusuka ku-analog kuya kwedijithali.
Ubuchwepheshe befoni ye-2G bufaka ucingo nokubhala umbhalo, kanye nezinsizakalo zedatha njenge-SMS, imilayezo yezithombe, ne-MMS.
Nakuba i-2G ithathe indawo engu-1G futhi iphethwe yizobuchwepheshe ezichazwe ngezansi, isasetshenziswa emhlabeni jikelele.
Isivinini esikhulu se-2G nge-General Packet Radio Service (GPRS) i-50 Kbps noma i-1 Mbps ngezindleko zedatha ezithuthukisiwe ze-GSM Evolution (EDGE). Okuningi "
2.5G & 2.75G: Okokugcina Idatha, kodwa Yehlisa
Ngaphambi kokwenza ukuxhuma okukhulu kusuka kumanethiwekhi angenawaya angama-2G kuya ku-3G, i-2.5G ne-2.75G engaziwa kakhulu yayisimiso esinqunyiwe esasifaka igebe
I-2.5G yokwethulwa kwekhwalithi entsha yokushintsha iphakethe ephumelela kakhulu kunalokho esasetshenziswa ngaphambili.
Lokhu kwaholela ku-2.75G okuhlinzekela ukukhushulwa kwamandla amathathu. 2.75G nge-EDGE yaqala e-US ne-GSM amanethiwekhi (AT & T abe ngowokuqala). Okuningi "
I-3G: Idatha engaphezulu! Ikholi yekholi ne-Inthanethi yeselula
Amanethiwekhi we-3G aqaliswa ngo-1998 futhi amele isizukulwane esilandelayo kulolu chungechunge; isizukulwane sesithathu.
I-3G ihambele ngesivinini esisheshayo sokudlulisa idatha ukuze ukwazi ukusebenzisa ifoni yakho ngezindlela eziningi ezifuna idatha, njengokufana nekholi yevidiyo ne-intanethi yeselula.
Njengesi-2G, i-3G yavela ku-3.5G no-3.75G njengoba ezinye izici zaziswa ukuze zilethwe nge-4G.
Ijubane elikhulu le-3G lilinganiswa libe yi-2 Mbps kumadivaysi angahambelani nama-384 Kbps ekuthumeni izimoto. Isivinini esikhulu se-HSPA + siyi-21.6 Mbps. Okuningi "
I-4G: I-Standard Standard
Isizukulwane sesizukulwane sesine sibizwa ngokuthi i-4G, esakhishwa ngo-2008. Sisekela ukufinyelela kwewebhu yeselula njengo-3G kodwa futhi nezinsizakalo zokudlala, i-HD yeselula ye-HD, i-video conferencing, i-3D TV nezinye izinto ezifuna ukuvinjelwa okuphakeme.
Ngokuqaliswa kwe-4G, ezinye izici ze-3G zisusiwe, njenge-technology yomsakazo we-spectrum; Ezinye zengezwe kumazinga aphezulu kakhulu ngenxa yama-antenna ahlakaniphile.
Ijubane elikhulu lenethiwekhi ye-4G uma idivayisi ishukunyuka yi-100 Mbps noma i-1 Gbps yokuxhumana okuphansi okuhambayo njengokungathi kumile noma kuhamba. Okuningi "
5G: Ukuza maduzane
I-5G ubuchwepheshe obungenazintambo obungasetshenziswanga kodwa okwenzelwe ukuthuthukisa ku-4G.
I-5G ithembisa kakhulu amazinga wedatha esheshayo, ukuxhumeka okuxhumekile okuphezulu, i-latency ephansi kakhulu, phakathi kwezinye ukuthuthukiswa. Okuningi "
