Standards Evolution: Commercial Broadband Technology
Note:
Dates shown are standards completion dates (or expected completion dates). Initial deployment lags standards by >1-3 years.
Initial VoIP not as spectrally efficient as Optimized VoIP. Optimized VoIP for 802.16 is TBD.
Mobility indicates when each particular standard supports mobility inter-operability between the terminal and BTS.

EV-DO Rev A Data Rates and Capacity
3.1 Mbps peak rate per user on outbound and 1.8Mbps peak rate per user on inbound in 2x1.25 MHz
Large range of data rates available - lowest at 4.8Kbps nominal
Current capacity estimates
Between 900 and 1.2 Mbps per sector per outbound
carrier (2x1.25 MHz) Between 450 and 600 Kbps per sector per inbound
carrier (2x1.25 MHz)
Additional capacity increase with up to 6 sectors persite or through use of Intelligent Antennas
