Ok,

I have three 90 degree pac wireless horizontal sectors
two rb532a
one 532 is running two engenius 400mw cards connected to sectors with 3 feet of lmr400 ufl to female to the radio card.
the other 532 is running on sector with a 400 mw card and the other 400mw card is running 5ghz as a backhaul to another tower with a 2foot dish 29dbi

the sectors are 17dbi i believe


on the one 532a with two sectors, i have two pppoe servers running on that one routerboard.. i now have 29 customers on one pppoe server and 23 customers on the other pppoe server

so that is 53 customers i have connected to two sectors. here recently when i added two more customers to those ap's.. i have been experiencing very high ping times.. but it is only on that ap to the customer

if i do a ping from that routerboard to another routerboard, im using ospf by the way, the ping times are fine. I do have canopy equipment that interferes a little about 4 miles away but they haven't given me a real big problem yet.

i am using 2.4ghz 10mhz on one antenna and 2.4ghz 5mhz on another antenna and 2.4 ghz g on a completely different routerboard that is on the same tower.

is there a set limit on how many people can connect and run on one routerboard? is it per radio card? per pppoe server?

i'm stumped i've changed frequencies, helped a lil but not much.. i temporarily disconnected a few customers, it helped out somewhat... is it that i need to upgrade this 532 to a 600 or a 433?

which is better performing? 433 or 600?

any ideas?

What are you doing for QoS?

i used various kinds, i've tried simple queues and queue trees..

be sure sectors are seperated as much as possible (at least a meter or more).
Would also do some good to use a third router/radio in seperate enclosure to isolate the signals.

Also keep in mind that even though the band is 10/5MHz wide the receiver still listens to the full 20MHz.
This means that you must use 1 6 11 non-overlap channels.

EDIT:
You may even want to replace the channel 6 sector antenna with a vertical sector for additional polarity seperation.

I don't mean to argue, but can you give a source that says that about listening on 20MHz channel? I've read that, and I'm still trying to wrap my head around it.

Only the older cards listen on 20mhz such as the CM9

It is something I'd like to understand better. If the card is capable of 40/20/10/5, why does it always listen on 20MHz? Shouldn't it listen for all 40MHz if that is the case?

I take it, from your comment JCWN, the R52 and above doesn't have this limitation? CM9 is what, 5004 chipset, R52 is 5006, right?

From what I have learned about interference. I have spaced them out as far as I could and still sometimes I have to put them closer together to get the right amount quality. The signal's might be a little worse but the quality is there. I have a lot of a few providers in my area that are using canopy and amps. What's the best way to handle amp'ers?

It has to do with the LNA for received signals.
A 40Meg channel is really 2 - 20Meg Channels (check it out on a spec-anal).
The LNA is not under control of the Atheros chipset.

That is how I understand it....

Ok, got it.
I guess my question now, the low noise amp is different than the broadcast, right? PA is power amplifier?
