Scenarios 


The following scenarios were tested outdoors:




Scenario 1: Back-to-back, no vertical separationScenario 2: Back-to-back with .5m vertical separation


Test details


Unit 1: TNA-301 configured in Station Mode

Unit 2: TNA-301 configured in Access Point mode


Both units were configured to have the same SSID, security keys, etc.  Testing was performed in a semi-urban area with buildings in the immediate vicinity.   The AP And Station were located in a position on the pole to try to minimize reflections from nearby structures.



Test Results


For both scenarios, there was no observable interference.  Unit 2, the device operating in station mode, did not detect any other access points near by.


Other Notes

A third test was performed with the AP and station being positioned at a 90° angle away from each other on the pole, as shown in the diagram to the right.  


The results however were inconclusive due to reflections from nearby structures.


Additional testing in a less dense area will be performed in the future.



Recommendations


It is recommended that you install your devices in an ABAB configuration in order to facilitate efficient channel reuse.
