A network engineer is working on a design for a wireless network that must support data, voice, and location services. To support these services, which access point placement must the engineer use?

Corner-only placement does not provide sufficient geometric distribution of AP positions to achieve accurate triangulation across the entire coverage area.

Cisco location services rely on RSSI triangulation from multiple APs (via Cisco MSE/CMX), which requires APs to be geometrically distributed at both the perimeter and corners of the coverage area so clients are visible from multiple directions. This placement ensures the minimum of three AP readings are spatially diverse enough to minimize location error across the full area.

Perimeter-only placement without corner APs leaves triangulation gaps, reducing location accuracy particularly for clients near the center of the coverage zone.

Indoor and outdoor is a general deployment classification, not a specific AP placement methodology that satisfies the geometric requirements of location service triangulation.
