I have about 50 clients on with no problems...

But post your setup here and others can help...
And post how your location is and so on...

That was a useless post that should be deleted...

50-75 clients is easily attainable with the correct hardware and software configuration.

What is the correct hardware and software configuration? Let's say we have powerful cards and 1m cables to antennas and we take into account polarization and Fresnel-Zone. What are the next steps to connect more clients?

jwcn, can you post your config to support 50 - 75 clients?

I have only been able to get about 30 per AP

Thanks

The topic is dicussed wired at the moment. To say what number an AP can
handle you've to talk about parameters:
- number of segments (wireless cards)
- band and distance between frequencies/Antennas
- expected bandwith/quality for each user (voip?)

For home-users which expect 3MBit down/384kBit up with an acceptable
quality (which may differ from user to user) we see around 20-25 users per
segment in 5GHz with channels spaced as far as possible using sector antennas.
If you're using non-MT clients, number might be smaller as bandwith-limitation
per client is a problem (you've to limit upstream at the client).

Numbers depend heavily on the usage and what qos you want to offer.
If you've 20 filesharers on a segment you'r never get happy.
If you've very friendly users you might put 50 on a sector. But you've to
be carefully if users expect to use Voip. This needs very high quality.

When we see a segment with >25 clients we schedule the next upgrade
as we're not willing to spend a lot of time at the phone to keep users friendly.

I've posted a screen shot of winbox with a single 802.11B AP, with 106 users connected, pushing just over 6mbps traffic. Some keys to getting these kinds of results:

-Relatively low noise floor
-Almost all clients are connecting at 11mbps RX/TX with short preamble
-We use RTS/frag settings of 512/1024 (respectively) on the client CPE's
-XR2 card connected to a 120deg h-pol sector
-Clients that have integrated router, QoS and bandwidth controls (like Tranzeo CPQ, or Ubiquiti PS2)
-We also use WPA/AES encryption on all connections
-Clients TX power turned down as to not over power the AP and create self interference
-Ping times can spike on occasion, but as you'll notice in the screen shot, they average @ 55ms for a gigantic 1450 byte ICMP packet

Looking around at the rest of the winbox session should give you some other clues.

well running a WISP is always a challenge u miss it u loose it, situations changes every new day, "its not like install it and forget it". u shd be sound enough to understand the RF manipulation, implementation.
its not about how many CPE can be associated wid a single AP, but the thing which matter is what type of users u have got is he is mania of downloading and uploading in GBs, if yes then a 10-15 CPE can kill your AP. and off-course the ghost of RF interference, my GOD interference, ur network trap in interference then GOD save u.

my suggestions:
1. Never compromise in quality, always use cards like XR2, SR2, XR5, SR5, R 52, R5H ALWAYS CARE FULL IN SELECTION OF RIGHT CPE.
2. Use high quality and reputed antennas. and use top quality pigtails.
3. avoid extremely heavy users to become ur customer if possible.
4. always do RF planning and keep a sharp look on other service provider and their frequency.

Well I calculate it like this

over the air rate = 54mbit/s
usable ethernet level throuput : 35mbit/s (best case no noise)

required bandwidth per client : 1 mbit/s ethernet level
so
35/1 = 35 users

I dont know if its right but it works for me this way.

I would break a leg for wireless-test.
I've been able to push the clients connected on a single AP radio from 20 (before ROS3.15) to 40 (Wireless-test enabled) and still getting awesome results.
Profiles of 2Mbit/256k.
All the network is Mikrotik based (CPE included)
