Explaining Wireless LAN Technology Standards

Unlicensed Frequency Bands

Unlicensed Frequency Bands

Reflection: Occurs when RF waves bounce off objects (for example, metal or glass surfaces).
Scattering: Occurs when RF waves strike an uneven surface (for example, a rough surface) and are reflected in many directions.
Absorption: Occurs when RF waves are absorbed by objects (for example, walls).
