What consideration is found in PtMP systems that is not found in PtP systems?

• A. Interference avoidance
• B. SINR optimization
• C. Frequency selection
• D. Airtime management

Answer: D

Explanation:
* 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:
* Each client gets a fair chance to communicate
* High-priority traffic isn't starved by low-priority traffic
* 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.
