• PtMP (Point-to-Multipoint): A single access point (AP) communicates with multiple client devices. This means the AP needs to manage how the available airtime is shared among those clients.
• Airtime Fairness: Mechanisms are needed to ensure that:
• PtP (Point-to-Point): A dedicated link only has two devices, eliminating the need for complex airtime management.
• Considerations in Both: While interference, SINR, and frequency selection are important in both PtMP and PtP systems, the need for airtime management is unique to the multipoint scenario.

References:

• Wireless Network Topologies (PtP vs. PtMP): Explanations of the differences in how communication is managed in each scenario.
• TDMA (Time Division Multiple Access): A common airtime sharing method used in PtMP systems.

• Authentication: Verifying "who" the user or device is (e.g., via passwords, certificates).
• Authorization: Controlling "what" a user or device can do once authenticated (e.g., read-only vs. read/write permissions).
• Combined for Security: Both are essential. Authentication alone doesn't control access levels, and authorization without verification is meaningless.

References:

• Identity and Access Management (IAM): Articles and resources outlining the core principles of authentication and authorization.
• Cybersecurity Best Practices: Guides on securing systems will often emphasize the need for both authentication and authorization controls.

• 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.

• Wireless vs. Wired Network Design: Comparisons of pros and cons, highlighting how use cases guide the choice.
• IoT Solution Planning: Materials on defining requirements before selecting technology.
