1X
One Times Radio Transmission Technology (the “one times” refers to the frequency
spectrum). Also known as Sprint Vision. Supports Internet connections with data
rates up to 153 kbps. Actual speed depends on the network conditions. Compare
to 1xEV-DO.
1xEV-DO
A high-speed standard for cellular packet data communications. Also known as
Sprint Power Vision.
1xEV-DO Rev. A supports Internet connections with data rates up to 3.1 Mbps
(downlink from the network) and 1.8 Mbps (uplink to the network). Average data
rates are 600 kbps - 1.4 Mbps (downlink from the network) and 350-500 kbps
(uplink to the network).
1xEV-DO Rev. 0 supports Internet connections with data rates up to 2.4 Mbps
(downlink from the network) and 153 kbps (uplink to the network). Average data
rates are 400-700 kbps (downlink from the network) and 40-80 kbps (uplink to the
network)
Actual speed depends on the network conditions. Compare to 1X.
bps
bits per second—The actual data speed over the transmission medium.
broadband
High-speed wireless services optimized for data. Sprint Mobile Broadband is the
next evolutionary step for the Sprint Power Vision Network.
CDMA
Code Division Multiple Access—A wideband spread spectrum technique used in
digital cellular, personal communications services, and other wireless networks.
Wide channels (1.25 MHz) are obtained through spread spectrum transmissions,
thus allowing many active users to share the same channel. Each user is assigned
a unique digital code, which differentiates the individual conversations on the
same channel.
dBm
decibels relative to 1 milliwatt
