Inkcazo:
I-teknoloji ye-TDMA, emele i- T imeD ivision M ultiple I- ccess, iyinqanaba lefowuni elifakwe kwizinga eliphezulu le- GSM , eli li-teknoloji yefowuni esetyenziswa kakhulu kwihlabathi.
I-TDMA isetyenziswe kwisiseko sesizukulwana sesibini ( 2G ) zefowuni njenge GSM. Inxalenye enkulu yesithathu ( 3G ) yesistim zefowuni zixhomekeke kwi- CDMA ye-GSM. I-3G ivumela ukukhawuleza kwedatha ngaphezu kwe-2G.
Ngoxa i-TDMA kunye ne-CDMA zifezekisa injongo enye, zenza oko zisebenzisa iindlela ezahlukeneyo. I-teknoloji ye-TDMA isebenza ngokuhlula ishaneli nganye yesiganeli sejithali kwisithuba esinexesha elinesithathu ngenjongo yokunyusa inani leenkcukacha ezithathwe.
Abasebenzisi abaninzi, ngoko, banokwabelana ngesinye isangqa ngaphandle kokubangela ukuphazamiseka ngenxa yokuba uphawu luhlukaniswe ngamaxesha amaninzi.
Ngexa intetho nganye idluliselwa ngokuthe ngenye kwithuba elifutshane elifutshane kunye ne-TDMA iteknoloji, i-CDMA ihlukanisa unxibelelwano ngekhowudi ukwenzela ukuba iifowuni ezininzi zihanjiswe kwisitya esinye.
Iinjongo ezinkulu zefowuni e-US ayisasebenzisi i-TDMA.
Sprint, Virgin Mobile , kunye neVerizon ukusebenzisa i-CDMA ngelixa i-T-Mobile kunye ne-AT & T isebenzisa i-GSM.
Ukubizwa:
tee-dee-e-eh
Kwaziwa njenge:
Ixesha leD ivision M ultiple I- ccess
U mzekelo:
I-teknoloji ye-TDMA ifakwe kwi-GSM ephezulu.
