When designing a WLAN, AP placement is important. Which option describes how to rank the density of APs needed to support location services versus data and voice services?

Question

Options

• AData services have the lowest density of APs compared to location services, which has the
• BData services have a lower density of APs compared to location services, but more than voice.
• CVoice services have the highest density of APs over location and data services.
• DVoice and data services require a higher density of APs than location services.

• A
  90% (18)
• B
  5% (1)
• C
  5% (1)

Explanation

AP density requirements rank from highest to lowest: Location Services > Voice > Data. Location services (e.g., RFID tracking, client location via triangulation) require the highest AP density because clients must be 'heard' by at least three APs simultaneously for accurate positioning, demanding tight AP spacing (typically every 40–70 feet). Voice services require medium-high density to ensure seamless roaming with consistent RSSI (typically -67 dBm or better) and low latency handoffs. Data services require the least density, needing only sufficient coverage and throughput, with less sensitivity to roaming performance. Option A correctly states data has the lowest density and location has the highest.
