Max Wi-Fi connections question

[Ed lawson]

I'm sure someone in the group has a real world answer to this
question.  My local school is seeking to have Wi-Fi in every classroom
with each classroom having up to 30 devices using the network
simultaneously.  I questioned this and was told the appropriate
commercial grade router is capable of maintaining simultaneous
connections with 120 devices and throughput is fine.  This sounds a bit
optimistic to me, but I'm older than gray hair and hardware was never
something I knew much about.

Part of my suspicion is based on the school equating an advanced
computer class with a class where students can learn to use a 3-D
printer. While that is a neat thing to do, not sure why that is an
advanced computer class. 

Thank you in advance.
