An existing wireless network was designed to support data traffic only.

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.

Other options explained:

C: Directional antennas limit overlapping coverage, reducing triangulation accuracy.

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.
