Tanthauzo:
Teknoloje ya TDMA, yomwe imayimira Phunziro D ivision M ultiple A ccess, ndilo foni ya foni imene yaikidwa mu GSM yapamwamba kwambiri, yomwe tsopano ndiyo yogwiritsidwa ntchito kwambiri pa matelefoni a foni.
TDMA imagwiritsidwa ntchito mu mawonekedwe a foni yamakono ( 2G ) monga GSM. Maofesi akuluakulu atatu ( 3G ) a foni amagwiritsidwa ntchito makamaka pa GSM mpikisano wa CDMA . 3G imalola kuti deta ifulumire kuposa 2G.
Ngakhale kuti TDMA ndi CDMA zonse zimakwanitsa cholinga chimodzi, zimatero pogwiritsa ntchito njira zosiyana. Teknoloji ya TDMA imagwira ntchito pagawa njira iliyonse ya digito ya m'manja kuti ikhale nthawi zitatu kuti cholinga chake chiwonjezere kuchuluka kwa deta.
Ogwiritsa ntchito ambiri, akhoza, kugawana njira yomweyi popanda kuwonongetsa chifukwa chizindikirocho chimagawidwa nthawi zambiri.
Pamene zokambirana zonse zimafalitsidwa pang'onopang'ono kwa nthawi yayitali ndi teknoloji ya TDMA, CDMA imasiyanitsa mauthenga ndi code kotero kuti maitanidwe angapo amatha kupitsidwanso njira yomweyo.
Mankhwala akuluakulu a foni ku US sakugwiritsanso ntchito TDMA.
Sprint, Virgin Mobile , ndi Verizon Wireless ntchito CDMA pamene T-Mobile ndi AT & T amagwiritsa ntchito GSM.
