![]() You can figure out a great deal with that information. Get the Aruba document(s) regarding how ARM calculates interference indexes (intf_index). This is an art more than a science so lots of testing will be required. If you start lowering power levels then consider removing some lower data rates. this causing a clumping of clients trying to get on the AP with power level 18 (it can happen but may not). If you use a larger spread, say 18/12 then some APs will be 18 while many are 12. Our normal levels are 18/15 for the 4 really high density sites mentioned above. We go as low as 9/6 in our 'ballroom' while some high density areas are 12/9. Try to keep power levels fairly close for max/min. Turning off HT-40 really helps in many ways (you've already done that).īe careful with adjusting power levels. Turn off at least 1/3 to 1/2 of the 2.4ghz radios (site survey needed for specifics). When they are in the hallways, you get several bad things: users are on the other side of the wall(s) so they get reduced signal, APs will turn power down (see first point), interference indexes calculated by ARM will be higher than normal thereby adding possible issues with ARM, etc. This means putting them in rooms and not hallways. Here are some suggestions I would make.ĭon't let APs see each other directly if possible. ^^ This!!! We have an extremely dense deployment of Aruba with 4 of our sites having over 250+ AP and 3000+ clients daily in each. "You may have an issue because all those APs are in the hallway and they can hear each other too much vs if you had them inside the offices. Are you using "Drop Broadcast and Multicast" on all of your Virtual AP profiles? Disabling 40 MHZ channels is good, but it will not do anything for 2.4ghz (b/g) channels it would only help with 5ghz (a) channels.Ħ. 12 or 9 is probably the lowest that you want them on.ĥ. ![]() It seems like all of your APs are at 15, which means they could go lower. For now, do not use the RX sensitivity Tuning Based Channel Reuse, just to see what happens. We have 14 controllers 3400 and 500 AP's model AP125 connected, is our version of ArubaOS 6.2.1.3Ĥ. We have enabled the ARM with the Client Aware enabled and no longer used the HT-40 just to avoid the aggregation of channels. My question is: Is it possible to use the RX Sensitivity Tuning Based Channel Reuse to try to mitigate this interference? Sometimes we have 90% occupancy of the channel in one area so the RX received. The fact is that even decreasing the power of the ARM have the co-channel interference, as can be seen in the attached figure. We have a highly dense network with multiple access points near and including the signal leakage between floors ends up affecting our use of channel time that is an AP with a high TX directly affects the others that are on the same channel, the next time or not.
