When locating access points, system designers often use the availability of AC (alternating current) electrical outlets to base decisions on where to install access points. In some cases, companies only locate access points near AC outlets and within reach of a typical six foot electrical cord. Or, they'll look for a convenient location to install new outlets at points where it's suitable to run conduit and mount outlet boxes. All of these situations limit the location of access points and can incur significant costs if new outlets must be installed.
