Wireless Protocols

Wireless protocols are fundamental frameworks that govern how devices communicate without physical connections, forming the invisible backbone of our modern connected world.

Core Characteristics

• Signal Transmission: Uses electromagnetic spectrum for data transfer
• Standardization: Defined by international bodies like IEEE and ITU
• Layer Implementation: Operates within the OSI model framework
• Security Features: Incorporates encryption and authentication mechanisms
