We're planning to provide WiFi at train system. Each train has 5 carriages and each carriage has one AP.
How we can provide adjacent channels for the carriages APs, so their signals will not bleed over into each other's channel, disrupting both channels?
puting into consideration that the system has two close railways. so, the AP on one carriage will be affected by other carriages on the same train and by other carriages on the other railway train.
for your consultation
