Understanding Macro and Micro Cells

In areas where the AP traditionally has a wide-area coverage clients connected close to the AP are the most
spectrum efficient since they are in the near field and negotiate typically at the highest data rates while clients
farther away compete at lower data rates. The lower rate clients that are farther away tend to take more airtime
than the closer clients running at faster rates. This results in non-linear traffic and increases the overall channel
utilization as clients compete for "airtime".
