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

AInterference avoidance

BSINR optimization

CAirtime management

DFrequency selection

Show Suggested Answer

Suggested Answer: C

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.

TDMA (Time Division Multiple Access):A common airtime sharing method used in PtMP systems.

I don't know about you, but I'm feeling a little 'point-to-point-ed' right now. D all the way!

Airtime management? More like 'Nightmare Management' amirite? C is the way to go, folks.

Hmm, this is a tricky one. I'm going to go with B. SINR optimization. Maintaining a good signal-to-interference-plus-noise ratio is crucial in a multi-point environment.

Airtime management is another consideration that becomes more complex in PtMP compared to PtP systems.

Yeah, interference avoidance is also key in PtMP setups to ensure smooth communication.

I think you're right. SINR optimization is definitely important in PtMP systems.

But in PtMP systems, there are multiple clients sharing the same access point, so interference avoidance is crucial.

D. Frequency selection seems like the most logical answer to me. PtMP systems need to carefully manage frequency allocation to avoid interference between clients.
