3rd Generation Partnership Project
BeiDou Navigation Satellite System
BeiDou
A Chinese system that uses a series of satellites in geostationary and middle earth orbits
to provide navigational data.
Bit Error Rate — A measure of receive sensitivity
BER
Decibel = 10 x log10 (P1/P2)
P1 is calculated power; P2 is reference power
dB
Decibel = 20 x log10 (V1/V2)
V1 is calculated voltage, V2 is reference voltage
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,
dBm
because of the difference in scale (milliwatts vs. watts).
DRX
Discontinuous Reception
EIRP
Effective (or Equivalent) Isotropic Radiated Power
EMC
Electromagnetic Compatibility
EMI
Electromagnetic Interference
Federal Communications Commission
The U.S. federal agency that is responsible for interstate and foreign communications.
FCC
The FCC regulates commercial and private radio spectrum management, sets rates for
communications services, determines standards for equipment, and controls broadcast
licensing. Consult http://www.fcc.gov.

Frequency Division Duplexing
A European system that uses a series of satellites in middle earth orbit to provide
Galileo
navigational data.
GCF
Global Certification Forum
