IxTest – Wi-Fi Assessment 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 IxTest – Wi-Fi

Assessment

What’s the signal strength? a

Is there co-channel interference? a

Is there connectivity? a What voice quality can I expect to

achieve? a

What video quality will I get? a How will a device roam between

APs? a How many users can the network

support? a What QoE will I see when the

network is loaded? a How well do different devices work

on the network a
