During a meeting, the network supervisor argued that they should use a 5 GHz band
in their new open-plan office setting, but the owner heard that the 2.4 GHz band is
the one to use since it has a shorter range. Who is right and why?

-The supervisor is correct. A 5 GHz band power's regulations and DFS
prevents signals from interfering.
-The supervisor is correct. A 2.4 GHz network does not have enough space
for separate networks.
