Challenge Problems
Push your limits with challenges.
Question 1
Consider a scenario with three stations (STA A, B, and C) where A and C can communicate with the AP, but not with each other. Describe the sequence of events when STA A wants to send data to the AP in the context of CSMA/CA.
💡 Hint: Break down the scenario into steps and consider the role each station plays.
Question 2
Discuss how the IFS mechanisms facilitate different priorities among transmissions in a mixed traffic environment.
💡 Hint: Think about the analogy of urgent messages demanded swift delivery as compared to normal ones.
