Measuring performance metrics according to design requirements

Active Site Survey

  • During an active manual survey, the radio is associated to the access point and has layer 2 connectivity, allowing for lowl evel frame transmissions.
  • If layer 3 connectivity is also established, low-level data traffic such as Internet Control Message Protocol (ICMP) pings are sent in 802.11 data frame transmissions.
  • Layer 1 RF measurements can also be recorded during the active survey.
  • However, upper-layer information such as packet loss and layer 2 retransmission percentages can be measured because the client card is associated to a single access point.
