When extending the range for a $2\mathrm{.}4$GHz WLAN, you can use nonoverlapping channels for adjacent coverage cells. However, there should be some overlap in coverage between those cells $($using nonoverlapping channels$)$ to prevent a connection from dropping as a user roams from one coverage cell to another. What percentage of coverage overlap should you recommend for these adjacent cells?
