Distinctive modulation schemes allow for EVDO to transmit varying amounts of data for each symbol, with extra sophisticated strategies featuring increased data rates.
The voice component can both be sent as Voice over Net Protocol (VoIP) or with a separate fallback provider devoted to voice-only, i.e. CDMA2000 one x provider. EVDO won't provide integrated voice and only focuses on giving significant-velocity data. Most CDMA mobile operators often adopt the cdma2000 one x fallback option to make sure voice assistance quality.
