Might not be the right subject line but here is my question. We have a fairly large MK install in a small down right now. We have 3 250ft towers around the town and all users have clear LOS. We are using some KP Performance 5GHz sectors and RB411AH with R52Hn cards in a dual chain setup. Most cpe are about between 1 to 3 miles of a tower and 95% are SEXTANT 5GHz dual chain cpe. Almost all are sitting around 90% ccq or better and speeds of 117 to 130Mbps over the air.
Everything is running NV2 and works really well, my question is we are seeing slower speeds on AP with say 40 cpe on them, actual bandwidth is not right maybe 10-15Mbps but we can only pull 4-5mbps at a customer site. The cpu usage is not high maybe 50% tops. My question is this, if we upgrade to say rb800 boards do you think we will see some improvement or is this just a cpe limit type situation we are seeing. Seems much above 20 or so we see these slow downs. I was wondering if RAM would help.
