For the AP 130 the technical max client load is 100 clients per radio, and with the two radios in a 130 that gives you 200 clients max. That said, that count is from a lab environment, with the lowest amount of traffic possible for those clients, so you likely won’t reach quite 100 in a non-lab environment. If all your clients are doing is sending email, you’ll probably get close to 100, but if they’re all making VOIP calls, streaming, downloading, etc, the number will be a bit lower.
There isn’t a technical limit for number of SSIDs on an AP, however we typically recommend no more than 5 in one area, otherwise you’ll create background interference due to too many signals in the same air space at once.
