Building a Wireless Network for an Apartment Complex?

Posted by Cliff on from the wave-of-the-future dept.

itwerx asks: "I've been asked to design a wireless infrastructure for an apartment complex. Tenants will pay an 'access deposit' and a monthly surcharge to get a PCMCIA/PCI/USB network card along with free installation and, of course, wireless Internet access. The buildings are arranged such that 2 WAP's per building should cover all the tenants (one WAP per side, far enough away to get line-of-sight through the windows). I do have a few concerns, however. All help is appreciated and when we're done we'll put up a HOWTO!"

"My concerns are the following:

  • Interference between WAP's (there's several buildings) - there are enough channels if we go 802.11a but cost is a concern.
  • Management of 'hitchhikers' - we're planning on manual assignment via DHCP/MAC address for tenants with others having all their HTTP requests get directed to an info page. Anybody done something different?
  • Interference from WAP's and other devices that may be owned by tenants! Should we just avoid the default channel and hope for the best?!?
What other things might I need to worry about?"

    Gotta love 'em.

    LowneWulf states:

    Put your entire complex on one SSID and one channel - each WAP will form a BSS, and devices should seamlessly roam between them.
    To which MarkKomus replies:
    If you have WAP's on different sides of buildings they most likely won't interfere with each other. Just keep the WAPs with the same channel as far apart as possible.
    LowneWulf states:
    Other peoples' devices shouldn't interfere with yours unless there is a LOT of devices.
    Which is rebutted by MarkKomus:
    Interference from WAP's and other devices that may be owned by tenants! Here could be your big problem.

    WEP is worthless, MAC based authentication is worthless, basically treat the cards as a public shouting space no more.

    You need end to end encryption for the users. That is easy for the Unix crowd but for "what does this button do" level folks something like PoPTOP and getting them to use PPTP may work out easier (although early PPTP isnt terribly secure either)

    I am an assistant network engineer at a large midwestern university...

    I never thought a wireless project like this would happen to me. I was sitting in the study lounge in my dorm when this sexy coed network engineer walks up and asks, "I see you have a seven layer OSI model. That really turns me on..."

    This is what business-class hotels now do - just provide an ethernet RJ-45 jack and a DHCP server... all a guest has to do is plug in, configure for DHCP, and reboot.

    Reboot?
