Bit Error Rate — A measure of receive sensitivity
BLER
Block Error Rate

Wireless protocol for data exchange over short distances
CDG
CDMA Development Group—a consortium of companies that develop and
promote the products and services for
wireless systems.
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.
CQI
Channel Quality Indication
COM
Communication port
CS
Circuit-switched
CSA
Canadian Standards Association
CW
Continuous waveform
dB
Decibel = 10 x log
10
(P1 / P2)
P1 is calculated power; P2 is reference power
Decibel = 20 x log
10
(V1 / V2)
V1 is calculated voltage, V2 is reference voltage
dBm
A logarithmic (base 10) measure of relative power (dB for decibels); relative to
milliwatts (m). A dBm value will be 30 units (1000 times) larger (less negative)
than a dBW value, because of the difference in scale (milliwatts vs. watts).
DC-HSPA+
Dual Carrier HSPA+
DCS
Digital Cellular System
A cellular communication infrastructure that uses the 1.8 GHz radio spectrum.
DL
Downlink (network to mobile)
DRX
Discontinuous Reception
