What are the challenges associated with signal blockage and obstructions in mmWave communication?

Answer explanation

mmWave communication faces challenges like high susceptibility to signal blockage from obstacles (e.g., buildings, trees) and atmospheric absorption, leading to reduced range and reliability in urban environments.

How does atmospheric absorption affect mmWave signals?

Answer explanation

Atmospheric absorption significantly impacts mmWave signals, leading to increased signal attenuation. This effect is more pronounced at higher frequencies, limiting the range and effectiveness of mmWave communication in certain conditions.

How does NOMA improve spectral efficiency compared to traditional methods?

Answer explanation

NOMA (Non-Orthogonal Multiple Access) improves spectral efficiency by allowing multiple users to share the same frequency band simultaneously, using power domain multiplexing, unlike traditional methods that allocate distinct frequencies to each user.
