Quick Poll: Performance Testing Experience
Single AP Performance testing?
Multi AP performance Testing?
Roaming (e.g. voice or video conferencing)?

It’s All About The Process, Process …
• Determine test purpose (e.g. QA, design guidelines, PoC,
competitive bake-off)
• Identify use cases
• Identify test tools, environment, clients, applications, etc.
needed to model use cases
• Create test plan/data workbook
• Acquire equipment and test facility
• Install/optimize network setup
• Execute plan
• Report findings/analysis

Example MethodologyMulti AP 11ac Only – Voice, Video Conferencing, Video Streaming and Data
• Testing was performed in a 20K square foot carpeted office space with no
interference in the 5 GHz bands.
• Six 11ac radios (AP-X, AP-Y or AP-Z) were used.
• Radios were configured to use 40 MHz channels.
• All 5GHz channels (including DFS) were available.
• All tests were performed in open air.
• All 5GHz channels were continually monitored with a spectrum analyzer, sniffer,
etc. to ensure that only the APs under test were using the channels.
• Vendor specific performance deployment/configuration best practices were
followed.
• All clients were distributed throughout the building as they might be during
normal peak usage times.
• Chariot was used to source/measure TCP data traffic.

Example Methodology Cont.Multi AP 11ac Only – Voice, Video Conferencing, Video Streaming and Data
• Skype was used for voice.
• FaceTime was used for video conferencing.
• VLC was used to source multicast and unicast (HTTP) video.
• All traffic was sent as Best Effort (000 / Decimal 0 / AC_BE) and it was up to the
WLAN system to identify the traffic and tag it appropriately.
• Background scanning was disabled on all APs.
• PoE (802.3af) was used for all APs under test.
• All tests were run using WPA2/802.1x
• Auto channel and auto transmit power were enabled for all APs.
• All tests were run 3 times with the middle performing results for each test
case/AP presented in the final report.
• Non client roaming tests were run for 1 minute and client roaming tests were run
for 3 minutes.
