Overview

This is probably one of the most frequently asked questions, but one for which there’s not always a short answer.

Of course, there’s a theoretical technical limit for the maximum number of concurrent associations, 128 per radio (so for a dual-radio model, 128+128=256). However, plan your network based on that; neither you nor your users will be very happy.

The following does not replace a site survey but gives you some guidance as to the recommended number of clients for each APX model based on three factors:

1. Environment
2. Type of devices being used
3. Type of apps/usage

A few examples:

• Suppose you're deploying APs in a school. In that case, the number of users and the usage in communal areas, such as the cafeteria, will probably differ greatly from the usage in each classroom.
• In an airport lounge, the type of usage and the users' expectations will differ greatly from a cafe or restaurant.

If you're a customer, we would advise you to work with your local Sophos partner to plan your deployment. If you're a Sophos partner and don't have the tools to survey, your local Sophos SE or (in some regions) your distributor can provide further help.
