[Cerowrt-devel] [Make-wifi-fast] more well funded attempts showing market demand for better wifi

[David Lang]

When I run the wifi network for the Scale conference, I will put multiple APs in 
each room. This last year I tried for ~1 per 50-75 seats in theater format 
(~25-30 in classroom format where there are tables).
