SELweb servers are able to support tens of thousands of students at the same time, but there must be sufficient bandwidth in the classroom or school for each student’s device to reach those servers. We recommend that schools limit the number of students who will be using SELweb at any given time so that each student will have at least 2 megabits/second while they are using SELweb.
For example, if students are using 20 wireless devices and connecting through a single wireless access point (often a little box with stubby antennae attached to the wall or ceiling), this wireless box MUST provide at least (20 * 2) = 40 megabits of bandwidth.
