HPE7-A01 · Question #146
Which standard supported by some HPE Aruba Networking APs can enable a customer to accurately locate wireless client devices within a few meters?
The correct answer is A. 802.1 Imc. Option A refers to 802.11mc, the IEEE amendment that introduced the Fine Timing Measurement (FTM) protocol, which enables devices to calculate precise distances by measuring the round-trip time of radio signals between an AP and a client - achieving location accuracy within 1–3…

Explanation
Option A refers to 802.11mc, the IEEE amendment that introduced the Fine Timing Measurement (FTM) protocol, which enables devices to calculate precise distances by measuring the round-trip time of radio signals between an AP and a client - achieving location accuracy within 1–3 meters. HPE Aruba APs implement this to power indoor positioning and real-time location services (RTLS).
Why the distractors are wrong:
- B (802.11ah / Wi-Fi HaLow): Designed for long-range, low-power IoT in sub-1 GHz bands - not indoor precision location.
- C (802.11be / Wi-Fi 7): Focuses on extremely high throughput and reduced latency, not location accuracy.
- D (802.11v): Handles BSS Transition Management (helping clients roam between APs) - a network management feature, not a location technology.
Memory tip: Think of "mc" as "measure carefully" - 802.11mc is the one that carefully measures timing to pinpoint where a client is. If an option mentions precise location within meters, FTM/802.11mc is the standard to recall.
