352-001 Question #799: Real Exam Question with Answer & Explanation
The correct answer is B: Increase the access point density to create an average inter-access point distance of less than 40. Cisco Context Aware Services requires specific AP deployment parameters to achieve acceptable location tracking accuracy, including minimum AP density and optimized transmit power.
Question
An existing wireless network was designed to support data traffic only. You must now install context Aware services for location tracking changes must be applied to the existing wireless network to increase the location accuracy? (Chose two)
Options
- AAdd access points along the perimeter of the coverage area.
- BIncrease the access point density to create an average inter-access point distance of less than 40
- CUse directional antennas to provide more cell overlapping
- DInstall additional access points in monitor mode where the co-channel interference would
- EFine tune the radio configuration of the access point to have a higher average transmission power
Explanation
Cisco Context Aware Services requires specific AP deployment parameters to achieve acceptable location tracking accuracy, including minimum AP density and optimized transmit power.
Common mistakes.
- A. 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.
- C. 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.
- D. 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.
