• QAM Constellations: QAM (Quadrature Amplitude Modulation) uses a constellation diagram where points represent unique combinations of amplitude and phase.
• Bits per Symbol: The number in QAM-XX indicates the number of points:
• Higher Data Rates: More points in the constellation enable transmitting more bits per symbol, leading to higher data rates at the same bandwidth.

• 60GHz Absorption: The 60GHz band experiences significant signal attenuation due to absorption by oxygen molecules in the atmosphere. This severely restricts the usable range of wireless systems operating in this frequency.
• Why Other Options Don't Apply:

References:

• 60GHz Propagation Characteristics: Technical papers discussing oxygen absorption and its influence on range limitations.
• Millimeter-wave (mmWave) Communication: Overviews highlighting the challenges and short-range applications of 60GHz systems.

• Health IoT Device Categories:

• Health IoT: Resources on healthcare + IoT will illustrate device types.

• Privilege Creep Defined: Gradual accumulation of excessive permissions over time, often due to users changing roles or access needs not being adjusted accordingly.
• Other Terms:

References:

• Principle of Least Privilege: Security best practice emphasizing the need to minimize access to only what's necessary.
• Access Control Models: Discussions of how privilege creep can violate security principles.
