An existing wireless network was designed to support data traffic only. You must now install context-aware services for location tracking. What changes must be applied to the existing wireless network to increase the location accuracy? (Choose two)
A.
Add access points along the perimeter of the coverage area.
B.
Increase the access point density to create an average inter-access point distance of less than 40 feet or 12.2 meters.
C.
Use directional antennas to provide more cell overlapping.
D.
Install additional access points in monitor mode where the co-channel interference would otherwise be affected.
E.
Fine tune the radio configuration of the access point to have a higher average transmission power to achieve better coverage.
For accurate location tracking in wireless networks, signal triangulation methods like RSSI, TDoA, or Angle of Arrival require:
A (Perimeter coverage): Adding APs along the perimeter improves location accuracy by minimizing blind spots and improving triangulation geometry.
B (Higher density, <40 ft spacing): Reducing inter-AP distance increases overlapping coverage, which provides more data points for accurate positioning.
D: Monitor mode APs can assist in location services but are secondary to proper placement and density.
E: Increasing transmit power may enlarge cell size but can decrease accuracy by reducing overlapping AP zones.
