• JSON Fundamentals: JSON (JavaScript Object Notation) is a text-based format for representing data in a structured, yet flexible way. Its key features are:
• JSON vs. Other Options

References:

• JSON Introduction: Clear definitions and examples of its syntax. (e.g., https://www.json.org/json-en.html)
• JSON Data Structures: Explanations of how arrays and nested objects are handled within JSON.

• 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.
