7 GLOSSARY
Table 7: Glossary of Terms
Abbreviation
Full Title
Explanation
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
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 Decawave’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. A number of such TDOA measurements at different locations can be
used to uniquely determine the position of the transmitter. Refer to Decawave’s
website for further information.
UWB Ultra Wideband A radio scheme employing channel bandwidths of, or in excess of, 500MHz
