An engineer is adding APs to an existing VolMLAN to allow for location based services.

The primary change to the network when adding APs for location-based services, such as VolMLAN, would be the AP footprint. This refers to the physical coverage area of the access points. Increasing the AP footprint enhances the ability to perform location-based services by improving the accuracy of triangulation and location tracking of devices. This is because a denser AP footprint allows for more precise determination of a device’s location within the network. References: CCNP Enterprise Wireless Design ENWLSD 300-425 and Implementation ENWLSI 300-430 Official Cert Guide, specifically the sections discussing location-based services and AP deployment strategies for optimal coverage and location tracking.
