Well i noticed that when i use ie the frequency 5700 with 5GHz mode selected and the exact same frequency in 5GHz-5Hz mode selected the results are way worse in the later.
To be more precise, when i use the first one in a link i get a signal of about -56 and when i use the second one the signal is about -90 and fails to even connect.
Am i missing something?
Whenever using 5MHz channels the signal should be about 6-9 dB better then 20 MHz channels.
Your speed would of course drop as a result of the lower bandwidth, I typically see ~5-7 Mbps TCP half-duplex with 5GHz-5MHz channel sizes.
HOWEVER, the 5GHz-5MHz channel is very very problematic for most cards I’ve tested. The 5GHz-10Mhz channel setting works much better for all cards. If I have a link that absolutely needs to use 5GHz-5MHz channels the only cards I trust are Ubiquiti’s.
Ubiquiti SR5/XR5 - Works
Engenius NMP-8602+ - Doesn’t Work Correctly (hit/miss, some cards work some don’t)
Routerboard R52/R52H - Doesn’t Work Correctly (all cards I tested failed over time)
Wistron Newb CM9 - Doesn’t Work Correctly (hit/miss, works one time then not another)
Wistron Newb DCMA-82 - Works, however the cards don’t function correctly in the RB4xx series
Original testing was done on RB532’s with 7 dBi omni antenna’s connected seperated by ~100ft.
Some outdoor testing was performed but only with the Ubiquiti cards are they were the only ones that I would say were reliable.
Cheers
