Testing and Reporting Reported metrics: Power RSSI Co-channel interference UDP downstream/upstream Max forwarding rate TCP downstream/upstream Max Goodput Voice MOS Video MDI Loss and jitter Client Roaming time (driver and OS dependent) Single Pass Site Survey - all measurements are conducted and recorded during a single pass HeatWave maps and individual measurements at every test stop available at the conclusion of site survey IxTest Wi-Fi Assessment
What s the signal strength? Is there co-channel interference? Is there connectivity? What voice quality can I expect to achieve? What video quality will I get? How will a device roam between APs? How many users can the network support? What QoE will I see when the network is loaded? How well do different devices work on the network IxTest Wi-Fi Assessment a a a a a a a a a IxTest Wi-Fi Assessment
