Some technical terms and abbreviations used in my documents or in papers I've cited

AAL — Ambient Assisted Living
A combination of ambient intelligence, where the environment is aware of the people in it, and the concept of assisted living.

CPS — Cyber-Physical System
The integration of computation with physical systems. Applications of cyber-physical systems in health care, for example, include assisted living technologies, bionics, and wearable devices.

DFL — Device-free localization
Technology that can determine the location of someone — typically in a building or a room — without requiring the person to wear a device, such as an RFID tag.

LoS — Line of sight
An unobstructed path between two objects that send and receive signals.

RF — Radio frequency
Oscillations in the frequency range used by radios, 3 kHz to 300 GHz.

RFID — Radio-frequency identification
The use of a wireless system that transmits data with RF signals, for tracking and identifying objects containing an RFID tag.

RSSI — Received signal strength indicator
The measure of the power in a received RF signal.

RTI — Radio tomographic imaging
A way to create a visual representation of the attenuation in signals in a wireless network, caused when an object interacts with the RF field.

WSN — Wireless sensor network
An array of sensor nodes that transmit and receive data from each other via RF signals.
