True or False: Cognitive radio is also referred to as 'smart radio'.

True
False
Sometimes true
Only in technical contexts

The correct answer is: True

Cognitive radio is indeed referred to as "smart radio" because it possesses the ability to intelligently detect and utilize communication channels that are currently unused. This technology allows cognitive radios to adapt to their environment by dynamically adjusting their transmission parameters based on the surrounding radio frequency conditions. The term "smart" highlights the radio's advanced capabilities in spectrum sensing, management, and efficiency, allowing it to make informed decisions to optimize communication. This adaptability is a key feature that distinguishes cognitive radios from traditional radios, which typically operate on a fixed frequency without the ability to adjust to changing conditions. This context reinforces the connection between cognitive radio and the concept of "smart" technology, supporting the assertion that the statement is true.
