A dense municipal office WLAN has solid SNR in primary work areas, yet airtime charts show slow stations consuming disproportionate medium time. What optimization most directly shrinks effective cell size and improves airtime efficiency?
Select an answer to reveal the explanation.
Short Explanation
Leaving 1 and 2 Mbps on is like keeping the slow lane open on a crowded bridge—one crawler eats everyone's time. Raise the minimum rates when coverage allows so stations speak faster and the cell edge pulls in.
Full Explanation
Low mandatory and supported rates enlarge effective cells and force long airtime occupancy for management and data frames. Raising minimum rates, when predictive and measured coverage still meet the design threshold, shrinks cells and improves airtime fairness. Preserving legacy low rates, blindly widening channels, or disabling WMM works against airtime efficiency.
