Testing and Reporting
•
IxTest – Wi-Fi Assessment
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?
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
