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 the
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 to3.1
Mbps (downlink from the network) and 1.8 Mbps (uplink to the
network).

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 roughly: for Rev. A: 600–1300 Kbps
(downlink from the network) and 300–400 Kbps (uplink to the
network); for Rev. 0: 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.

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.

CDMA 1X

Also known as 1X, this is a high speed standard for CDMA
cellular communications.

dormant

The packet data connection has the logical PPP session left open
while the underlying physical link (the radio channel) is released.
When traffic is to resume, a radio channel is reacquired and the
original PPP session resumes.
