A store is setting up wireless access for their employees. Management wants to limit the number of access points while ensuring all areas of the store are covered. Which of the following tools will help management determine the number of access points needed?

A signal locator assists in identifying existing wireless signals and measuring their strength but does not provide comprehensive analysis or recommendations for new access point placements. It is more useful for troubleshooting or optimizing existing networks rather than planning the installation of new ones.

WPA3 is a security protocol designed to enhance the security of wireless networks. While important for protecting network access, it does not contribute to the planning or determination of the number of access points required for effective coverage in a given area.

A heat map visually represents the coverage of wireless signals in a specific area, indicating where signal strength is strong or weak. However, creating an effective heat map typically requires data gathered from a site survey, making it a secondary tool rather than a standalone solution for determining access point needs.
