Since you will also have to get into access control you really should check into systems for Hotel WiFi. In fact just one AP per floor rarely works out. You usually put as many APs as it takes to get good coverage which can't be answered without trying out a deployment.
Nod to companies that supply hotel wifi like Cisco, Miraki and the others you find with https://www.google.com/search?q=hotel+wifi+systems
Hello guys .. I am a new guy in networking . actually my friend asked me to build wifi that covers his hotel with internet ,kind of service for customers.
The idea is to put an AP in each floor ,and all these aps are wired .all cables go down to a switch 8 ports . and this switch is connected to adsl router for internet feeding .
But I need your help to configure all APs
Which operation mode I have to use,as repeater or ap ?
What ip for each ap must be ?
Channels and ssids should be the same or different ?
Plz I need help for the correct configuration for all devices.
Sorry for my fantastic English .
