At Fairfield we have a cow (computers on wheels) with 22 laptops. These
use the school's stationary access points (a roaming setup where they all
have the same SSID). I have not gotten any complaints about no network
connectivity, so I am pretty sure a single access point can handle more
than 22 MAC addresses. These laptops (donated from the Dept of AG) are
all 802.11b, 11 Meg. As you know once one 11 Meg device connects to one
of these access points it drops all connections down to 11 Meg. I think
this may have some mitigating effect on everyone getting some bandwidth.
Also the school is on a single T1 (1.55 meg) so there is an upstream
bottleneck for web browsing. As far as saving and loading from the
server, no complaints.
At St Albans City School we have laptop carts with 8 laptops, it has
happened that people sign out two, and many times there are two being
served by one access points (total 16 devices). There are usually other
wireless devices being served by these access points at the same time
(teacher, coach and special educator laptops). These are 802.11g devices
and again, no complaints.
