Appendix A: Glossary
1X
One Times Radio Transmission Technology (the “one times” refers to the
frequency spectrum). Supports Internet connections with data rates up to
153 Kbps. Actual speed depends on network conditions. Compare to 1x
EV-DO.
1x-EVDO
A high speed standard for cellular packet data communications.
Rev. A supports Internet connections with data rates up to 3.1 Mbps (on
the downlink from the network) and 1.8 Mbps (on the uplink to the
network).
Rev. 0 supports Internet connections with data rates up to 2.4 Mbps (on
the downlink from the network) and 153 Kbps (on the uplink to the
network).
Average data rates: for Rev. A, 600–1300 Kbps (on downlink) and 300–
400 Kbps (on uplink); for Rev. 0, 400–700 Kbps (on downlink) and 40-80
Kbps (on uplink).
Actual speed depends on network conditions. Compare to 1X.
bps
Bits Per Second—Actual data speed over a transmission medium.
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, allowing many active users to share the
same channel. Each user is assigned a unique digital code which
differentiates individual conversations on the same channel.
CDMA 1X
Also known as 1X, this is a high-speed standard for CDMA cellular
communications.
Dormant
The packet data connection keeps the logical PPP session open while
the underlying physical link (radio channel) is released. When traffic
resumes, a radio channel is reacquired and the original PPP session
also resumes.
