CWNP Exam CWISA-102 Topic 1 Question 19 Discussion
Topic #: 1
What consideration is found in PtMP systems that is not found in PtP systems?
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.
References:
Wireless Network Topologies (PtP vs. PtMP):References 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.
