• Capacity Planning: The number of devices a wireless network can support is the primary determinant of its required capacity. This is because:

• Consumer Smart Devices Limitation: Many consumer-oriented smart devices are designed for simplicity and cost-effectiveness, leading to reliance on the crowded 2.4 GHz band.
• Consequences:

• 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.
