A company's IT department is setting up wireless access points throughout the office. To maintain a secure wireless network, they need to ensure that signal coverage is contained within the office premises without significant spill-over outside the building. What is the best practice regarding the power level adjustments of the wireless access points?
Always use the highest power level settings to ensure all internal areas are covered.
Set the power levels to the lowest setting that still ensures adequate coverage for the office premises.
Disable power level adjustments and keep a consistent high power level output for maximum performance.
Broadcast the SSID only while the office is closed to reduce the risk of intrusion during off-hours.
