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

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

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 [7] 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.

UWB

Ultra Wideband

A radio scheme employing channel bandwidths of, or in excess of, 500MHz

BLE

Bluetooth Low

Energy.

A low power means of data communication.
