  That is pretty close. Is the building two or more stories tall?
  Roof access?

  I think the SMC2532W-B is essentially the same radio as we use in one
  of our nodes. It will work fine.

  About the PCI to PCMCIA adapter, here is the advice I had for
  someone the other day, "The latest 802.11b radios and all the .11a/g
  cards are Cardbus, so I suggest the Buffalo/Melco PCI->Cardbus
  bridge, part number WLI-PCI-OP. It sells for about $30. See

  Our standard antenna is an 8dBi omni; we use up to 20 feet of radio
  cable to connect the omni to the radio.  To adapt the tiny MMCX
  connector on the radio to the fat connector (either SMA or N) on the
  cable, you need a "pigtail".

  We can provide you the latest software for your router.
