Full Title
Explanation
EIRP
Equivalent Isotropic
Radiated Power
The amount of power that a theoretical isotropic antenna (which evenly distributes
power in all directions) would emit to produce the peak power density observed in the
direction of maximum gain of the antenna being used.
ETSI
European
Telecommunication
Standards Institute
Regulatory body in the EU charged with the management of the radio spectrum and the
setting of regulations for devices that use it.
FCC
Federal
Communications
Commission
Regulatory body in the USA charged with the management of the radio spectrum and
the setting of regulations for devices that use it.
GPIO
General Purpose
Input / Output
Pin of an IC that can be configured as an input or output under software control and has
no specifically identified function.
IEEE
Institute of Electrical
and Electronic
Engineers
Is the world’s largest technical professional society. It is designed to serve professionals
involved in all aspects of the electrical, electronic, and computing fields and related
areas of science and technology.
PLL
Phase Locked Loop
Circuit designed to generate a signal at a particular frequency whose phase is related to
an incoming “reference” signal.
PPM
Parts Per Million
Used to quantify very small relative proportions. Just as 1% is one out of a hundred,
1 ppm is one part in a million.
RF
Radio Frequency
Generally used to refer to signals in the range of 3 kHz to 300 GHz. In the context of a
radio receiver, the term is generally used to refer to circuits in a receiver before
down-conversion takes place and in a transmitter after up-conversion takes place.
RTLS
Real Time Location
System
System intended to provide information on the location of various items in real-time.
SFD
Start of Frame
Delimiter
Defined in the context of the IEEE 802.15.4-2011 standard.
SPI
Serial Peripheral
Interface
An industry standard method for interfacing between IC’s using a synchronous serial
scheme first introduced by Motorola.
SRRC
Chinese State Radio
Regulatory
Commission
The radio regulation authority of the People's Republic of China with responsibilities
including spectrum management and frequency allocation.
TWR
Two Way Ranging
Method of measuring the physical distance between two radio units by exchanging
messages between the units and noting the times of transmission and reception. Refer
to Qorvo’s website for further information.
TDoA
Time Difference of
Arrival
Method of deriving information on the location of a transmitter. The time of arrival of a
transmission at two physically different locations whose clocks are synchronized is
noted and the difference in the arrival times provides information on the location of the
transmitter.
UWB
Ultra-Wideband
A radio scheme employing channel bandwidths of, or in excess of, 500 MHz.
WSN
Wireless Sensor
Network
A network of wireless nodes intended to enable the monitoring and control of the
physical environment.
