What is defined as the weakening of signal amplitude as the signal passes through a medium?
Attenuation:Describes the progressive loss of signal strength as it travels through a medium (like air, cables, walls). It's caused by factors like absorption, distance, and obstacles.
Other Phenomena:
Diffraction:Bending of waves around obstacles.
Reflection:Waves bouncing off surfaces.
**Scattering: ** Waves dispersing in multiple directions.

What function does the IEEE perform in relation to wireless technologies?
IEEE's Role:The Institute of Electrical and Electronics Engineers (IEEE) is a global organization critical in developing and promoting technical standards across various fields, including wireless technologies.
Standards Work:IEEE creates wireless technology standards like:
IEEE 802.11:Wi-Fi standards
IEEE 802.15.4:Basis for ZigBee, Thread, and other low-power networks

In the simplified three-layer model for wireless IoT, what is the universal primary function of the Perception layer?
Perception Layer:The foundation of an IoT system, it consists of sensors and actuators that:
Sense:Collect data about the environment or object being monitored.
Actuate:Potentially make changes based on commands (e.g., a smart valve opening/closing).
Transmit:Send gathered data to upper layers for processing.
What best describes the area covered or connected by a WWAN?
WWAN (Wide-Area Wireless Network):WWANs provide connectivity over extensive geographic areas, typically covering regions or even entire countries.
Cellular Technology:WWANs often rely on cellular networks (3G, 4G, 5G) offered by mobile carriers.

What is a common characteristic of Industrial IoT (IIoT) devices that is not a characteristic of all IoT devices?
IIoT Environments:Industrial IoT (IIoT) often involves deployment in harsh environments (factories, plants, outdoor sites) with:
Extreme temperatures
Dust & Vibrations
Exposure to chemicals or moisture
Ruggedization:IIoT devices are designed to withstand these conditions, ensuring reliability and longevity.
