Ukusebenza kweeNethwekhi zeeFowuni
Yintoni i-GSM?
I-teknoloji ye-GSM yi-teknoloji enokuthi (mhlawumbi mhlawumbi) kunye ne-80% yabasebenzisi abasebenzisa iifowuni kwiiselula zabo. Ngendlela ethile, ngumgangatho osemgangathweni kunye ongagqibekanga womnxeba ongasetyenziselwa ukuhanjiswa kweselula.
I-GSM yaqala ngo-1982 kwaye yabizwa ngoko emva kweqela eliyilungiselele, i-Groupe Spécial Mobile, apho i-GSM igama khona. Iprotocol yomthetho yaqaliswa ngokwayo eFinland ngo-1991. Ngoku ibizwa ngokuba yi-Global Systems yoThutho.
I-GSM ithathwa njenge-2G (isizukulwana sesizukulwana sesibili). Isebenza kunye neeseli, kutheni inethiwekhi ye-GSM ibizwa ngokuba yintanethi yeselula, kunye neefowuni ezisebenza kwi-GSM zibizwa ngokuba ngamafowuni. Ngoku yintoni iseli? Inethiwekhi ye-GSM ikwahlukana kwiiseli, nganye leyo ihlanganisa indawo encinci. Iifowuni (iifowuni) zifumaneka kwaye zixhunywe kunye nale seli.
Inethwekhi ye-GSM iqulethe kakhulu izixhobo zonxibelelwano (isango njl) njll, ziphinda ziphindaphinda okanye zidluliselwe, ezibizwa ngokuba ngabantu ababizwa ngokuba yi-antennas - ezi zakhiwo ezinkulu zetsimbi ezimiyo njengeendonga eziphezulu, kunye neefowuni eziphathekayo zabasebenzisi.
Inethiwekhi ye-GSM okanye inethiwekhi yeselula nayo yiplani ye-3G yonxibelelwano, ephethe idatha phezu kwenethiwekhi ekhona kwi-Intanethi.
SIM Card
Ifowuni nganye ifowuni ixhunyiwe kwinethiwekhi ye-GSM kwaye ichongwe kuyo ngekhadi leSIM (i-Subscriber Identity Module), elikhadi elincinci elifakwe ngaphakathi kwefowuni. Ikhadi leSIM ngalinye linikezelwe inombolo yefowuni, enekhowudi ekhuni kuyo, esetyenziswe njengento ekhethekileyo yokuchonga kweso sixhobo kwinethiwekhi. Yile ndlela ifowuni yakho ikhonkco (kwaye ingabikho nawuphi na umntu) xa umntu ediza inombolo yakho yefowuni.
i-SMS
Abantu be-GSM baye baqulunqa inkqubo yokunxibelelana eyona ndlela esincinci ukuya kudibaniso lwamaxabiso olubi kakhulu; Yisistim somfutshane (SMS). Oku kuquka ukuthumela imiyalezo emfutshane phakathi kweefowuni ezisebenzisa iifowuni zefowuni zokujongana nazo.
Ukubizwa: i- gee-ess-emm
Eyaziwayo Njenge: inethiwekhi yeselula, inethiwekhi yeselula
GSM kunye ne-Voice kwi-IP
I-GSM okanye iifowuni zeselula zongeza ubunzima obuninzi kwibhajethi yenyanga yabantu abaninzi. Ndiyabulela kwiLizwi ngaphezu kwe-IP ( VoIP ), ehamba phambili kwinethiwekhi yeselula kunye neziteshi ilizwi njengedatha kwi-Intanethi, izinto zitshintshile kakhulu. Ekubeni iVoIP isebenzisa i-intanethi esele ikhululekile, iifowuni zeVoIP zikhululekile okanye zixabiso elincinci kakhulu xa kuthelekiswa neefowuni ze-GSM, ngakumbi kwiifowuni zamazwe ngamazwe.
Ngoku, iifayile ezifana ne-Skype, i- WhatsApp , i-Viber, i-LINE, i-BB Messenger, i-WeChat kunye nabanye abaninzi banikela ngeefowuni zamahhala emhlabeni jikelele phakathi kwabasebenzisi babo. Abanye babo banikela iifowuni kwezinye iindawo ezincinci kunee-GSM. Oku kubangela ukuhla kweenombolo ze-GSM zefowuni ezibekwayo, kwaye i-SMS ibhekane nokuphela kokuthumela imiyalezo ngokukhawuleza.
Nangona kunjalo, iVoIP ayikwazanga ukubetha i-GSM kunye ne-telephony yendabuko ngekhwalithi yezwi. Ixabiso lezwi le-GSM lihlala libhetele kangcono kunee-intanethi ezixhomekeke kwi-intanethi njengoko okugqibela akuqinisekisi ukuba ukuthembeka kwaye umgca awunikezelwe njenge GSM.
