• Most Vulnerable In Transit: Sensitive data (passwords, health information, etc.) is most susceptible to interception while being sent over a wireless network. Encryption is crucial at this stage.
• Encryption at Rest and in Memory: While also important, these are often handled with different cryptographic techniques depending on the system.

References:

• Wireless Security Protocols: Details on encryption standards like WPA2/WPA3, TLS that focus on protecting data during transmission.

• Free Space Path Loss (FSPL): Describes how a radio signal weakens as it travels through open space, even without obstacles. It's caused by the signal spreading out, resulting in decreased power density at the receiver.
• Calculation: FSPL depends on distance and frequency.

• Requirements Drive Decisions: The decision between wired or wireless must align with the solution's overall purpose, performance targets, and operational constraints.
• Key Considerations:
• Other Factors are Important, But Secondary: Distance, PoE availability, specific applications all matter, but they are assessed within the context of the overarching business needs.
