I work for a K-12 school district that, like many locations, is relying more on client devices accessing the wireless for network access. There is discussion about going to a 1-to-1 initiative between district assigned devices and student. As my high schools have an average of 2000 students, I would need to support about 2000 client devices on my wireless network per high school. Currently, we assign district student devices to use a single SSID which uses a /23 subnet. This subnet does NOT have multicasting enabled and there are no future plans to enable multicast.
My solution is to increase the subnet to a /21 or even a /20 subnet mask to support the additional student devices but I'm concerned about creating too large of a broadcast domain on the subnet. I know it's not a good practice to create additional SSIDs on my wireless access points for the additional planned student devices (I'm currently up to four SSIDs).
Has anybody else set up this configuration in a K-12 environment? What is the recommended practice to accomplish this?
Thanks.
Ryan.
