newbie info on ap's

[sim123]

HI

I have an exisiting wireless LAN in my school with to AP's wired to the peer to peer network(this will be upgraded to client server this year.) I need to increase coverage throughout the school but do not have existing wired infrastructure. Am I right in thinking that all AP's have to be wired back to the hub/switch and that they cannot actualyy dasiy chain to themselves. Ideally I would want an AP in each class room to get the best coverage but the costs of wiring are prohibative - what is the best solution?
I could I suppose increase coverage with extra antennas but this would still mean all users accessing one AP

Thanks for any input
