The correct answer is B. Increase the access point density to create an average inter-access point distance of less than 40 E. Fine tune the radio configuration of the access point to have a higher average transmission power. Cisco Context Aware Services requires specific AP deployment parameters to achieve acceptable location tracking accuracy, including minimum AP density and optimized transmit power.

Why each option
Cisco Context Aware Services requires specific AP deployment parameters to achieve acceptable location tracking accuracy, including minimum AP density and optimized transmit power.
Adding APs only along the perimeter increases edge coverage but does not provide the interior AP density required for accurate triangulation of clients throughout the coverage area.
Cisco recommends an average inter-AP distance of less than 40 feet for location-aware deployments, as higher AP density provides more RSSI data points for accurate triangulation of client devices.
Directional antennas reduce the angular coverage of each AP, decreasing the number of APs that can simultaneously detect a client's signal and degrading location accuracy.
Placing additional APs in monitor mode in areas of co-channel interference degrades RSSI measurements across the network, which reduces location tracking precision rather than improving it.
Fine-tuning APs to maintain a higher average transmit power ensures that client devices are heard by a greater number of APs simultaneously, improving the RSSI-based location calculation accuracy used by Context Aware Services.
