Acronym or term Definition
3GPP
3rd Generation Partnership Project
BeiDou
BeiDou Navigation Satellite System
A Chinese system that uses a series of satellites in geostationary and middle
earth orbits to provide navigational data.
BER
Bit Error Rate—A measure of receive sensitivity
BLER
Block Error Rate
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+
EMC
Electromagnetic Compatibility
EMI
Electromagnetic Interference
FCC
Federal Communications Commission
The U.S. federal agency that is responsible for interstate and foreign
communications. The FCC regulates commercial and private radio spectrum
management, sets rates for communications services, determines standards for
equipment, and controls broadcast licensing. Consult www.fcc.gov .
Galileo
A European system that uses a series of satellites in middle earth orbit to provide
navigational data.
GCF Global Certification Forum
GLONASS Global Navigation Satellite System—A Russian system that uses a series of 24
satellites in middle circular orbit to provide navigational data.
GNSS
Global Navigation Satellite Systems (GPS, GLONASS, BeiDou, and Galileo)
GPS Global Positioning System
An American system that uses a series of 24 satellites in middle circular orbit to
provide navigational data.
Host The device into which an embedded module is integrated
