Glossary

A system that converts an analog signal, such as a sound picked up by a microphone or light entering a digital camera, into a digital signal.

A language and message format used by an application program to communicate with an operating system, application, or other service.

A unique address that identifies the access point/router that creates the wireless network.

A single-frequency electromagnetic wave that can be modulated in amplitude, frequency, or phase to convey information.

A system that converts a digital signal into an analog signal.

A Traffic Indication Message (TIM) that informs clients about the presence of buffered multicast/broadcast data on the access point.

Pre-programmed registers that contain chip-specific information and configuration. FICRs cannot be erased by users.

A digital signal pin that can be used as input, output, or both. It is uncommitted and can be controlled by the user at runtime.

Physical objects that are embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems of the Internet or other communications networks.

The layer that controls the hardware responsible for interaction with the wired, optical, or wireless transmission medium.

A small computer on a single metal-oxide-semiconductor integrated circuit chip.

A computer hardware unit that provides memory protection and is usually implemented as part of the CPU.

A type of non-volatile memory that permits data to be written to memory only once.

A collaborative coexistence mechanism for collocated wireless protocols.

The first and lowest layer of computer networking. This layer is closely associated with the physical connection between devices.

A board that connects electronic components.

A modulation method for representing an analog signal using only two levels (1 and 0).

A method of reducing the average power delivered by an electrical signal, by effectively dividing it into discrete parts.

A Serial Peripheral Interface (SPI) controller that allows the use of multiple data lines.

An electronic device that keeps accurate track of time.

Synchronous serial communication interface specification used for short-distance communication.

A unique identifier assigned to a wireless local area network.

A microchip that integrates all the necessary electronic circuits and components of a device or other electronic systems on a single integrated circuit.

A signal analyzer capable of analyzing digitally-modulated radio signals that may use any of a large number of digital modulation formats.
