Which standard supported by some Aruba APs enables accurate location of wireless client devices within a few meters?

• A. 802.11mc
• B. 802.11w
• C. 802.11k
• D. 802.11r

Answer: (A)

Fine Time Measurement in 802.11mc enables precise indoor positioning by using time-of-flight measurements between a wireless client and access points to determine distance. When an Aruba AP and a compatible client exchange these timing measurements, the system can triangulate the device’s location with accuracy of a few meters, especially when multiple APs participate. This is why the standard is the best fit for locating clients: it specifically provides a method for determining how far away a device is from APs, which directly supports accurate positioning. The other standards serve different purposes—802.11w protects management frames, 802.11k helps with roaming-related information exchange, and 802.11r speeds up handoffs—not location measurement. Remember that both the AP and the client need to support 802.11mc for this capability to work.
