Indlela Amanethiwekhi Efoni YaseKhaya asebenza ngayo
Kuyini i-GSM?
Ubuchwepheshe be-GSM ubuchwepheshe obunakho (ikakhulukazi) nabangu-80% wabasebenzisi baselula abasebenzisa ukwenza amakholi kumafoni abo omakhalekhukhwini. Ngandlela-thile, yiyona protocol ejwayelekile futhi ezenzakalelayo yenethiwekhi esetshenziselwa ukuxhumana kweselula.
I-GSM iqalile emuva ngo-1982 futhi yabizwa ngokuthi yiqembu eliyiqambile, i-Groupe Spécial Mobile, lapho i-GSM isibeka khona. I-protocol esemthethweni yaqala ngokwakho eFinland ngo-1991. Manje sekubizwa ngokuthi i-Global Systems for Mobile Communications.
I-GSM ibhekwa njengeprothokholi ye-2G (yesizukulwane sesizukulwane). Isebenza ngamaseli, yingakho inethiwekhi ye-GSM ibizwa nangokuthi inethiwekhi yeselula, futhi amafoni asebenza ku-GSM abizwa ngokuthi amafoni omakhalekhukhwini. Manje siyini iseli? Inethiwekhi ye-GSM ihlukaniswa ngamaseli, ngayinye ehlanganisa indawo encane. Amadivaysi (amafoni) atholakale futhi ahanjiswa nawo ngokusebenzisa lawa maseli.
Inethiwekhi ye-GSM iqukethe ikakhulukazi amadivaysi okuxhuma (amasango njll), abaphindaphindiwe noma abadluliselayo, abantu abavame ukubiza ama-antenna - lezi zakhiwo ezinkulu zensimbi ezimi njengemibhoshongo ephezulu -, kanye namafoni omakhalekhukhwini abasebenzisi.
I-GSM noma inethiwekhi yeselula nayo iyinsimu yokukhulumisana kwe-3G, okufaka idatha phezu kwenethiwekhi ekhona yokuxhumana kwe-inthanethi.
I-SIM Card
Ifoni ngayinye ephathekayo ixhunywe kwinethiwekhi ye-GSM futhi ikhonjiswe kuyo ngekhadi le-SIM (Subscriber Identity Module), okuyinto ikhadi elincane elifakwa ngaphakathi kwefoni ephathekayo. Ikhadi ngalinye le-SIM linikezwa inamba yocingo, i-hard-encoded in it, esetshenziswe njengesici esiyingqayizivele sokuhlonza idivaysi kwinethiwekhi. Yile ndlela ifoni yakho ikhala ngayo (hhayi omunye umuntu) uma othile efaka inombolo yakho yefoni yeselula.
I-SMS
Abantu be-GSM baye bahlakulela uhlelo lokuxhumana oluthile oluphansi olukhulumayo lokukhulumisana ngezwi; yile Myalezo Omfushane Wokuthumela Imiyalezo (SMS). Lokhu kuqukethe ukuthumela imiyalezo emifushane emkhatsini weselula ngokusebenzisa izinombolo zocingo zokubhekana nazo.
Igama lokubiza: gee-ess-emm
Futhi eyaziwa njenge: inethiwekhi yeselula, inethiwekhi yeselula
I-GSM ne-Voice over IP
I-GSM noma izingcingo zamangqamuzana zengeza isisindo esikhulu kubhajethi yanyangazonke yabantu abaningi. Ngenxa ye-Voice Over IP ( VoIP ), eyandisa inethiwekhi yeselula namashaneli izwi njengedatha phezu kwe-intanethi, izinto zishintshile kakhulu. Njengoba i-VoIP isebenzisa i-intanethi esivele ikhululekile, izingcingo ze-VoIP zikhululekile noma zingabizi kakhulu uma kuqhathaniswa namakholi we-GSM, ikakhulukazi izingcingo zomhlaba jikelele.
Manje, izinhlelo zokusebenza ezifana ne-Skype, WhatsApp , Viber, LINE, BB Messenger, WeChat kanye nabanye abaningi banikeza izingcingo zamahhala emhlabeni wonke phakathi kwabasebenzisi babo. Abanye babo banikeza izingcingo kwezinye izindawo ezingabizi kakhulu kunezingcingo ze-GSM. Lokhu kubangela ukwehla kwenombolo yezingcingo ze-GSM ezibekwayo, futhi i-SMS ibhekene nokuqedwa ngokuthumela imibiko yamahhala.
Noma kunjalo, i-VoIP ayikwazanga ukushaya i-GSM ne-telephony yendabuko ngekhwalithi yezwi. Ikhwalithi yezwi le-GSM isalokhu ingcono kunezingcingo ezisekelwe ku-Intanethi njengoba okugcina akuqinisekisi ukuthi ukuthembeka futhi umugqa awunikelwe njenge GSM.
