Another concern you should test for prior to deployment in regards to deployment is the difference with the manufacturers security options. Each product is capable of 128 bit encryption however there may be some incompatability issues with using 128 between them as we've occasionally noticed with various wireless manufacturers; only 40 bit encryption is required to be 802.11b and WI-FI compliant. Further with security, the actual radio manufacturer uses software encryption, so when you utilize WEP you shouldn't be too surprised at the performance hit; simply incorporage this into your overall site survey and network design to provide optimal connectivity for the applications. Also, in regards to EAP or LEAP, the RF card for Airport is made by another manufacturer that doesn't use or support LEAP (Cisco's version of EAP) however does support EAP so pay close attention to any additional security issues. Lastly, the cards themselves are 30mW devices so don't be alarmed if your RF coverage cells are slightly smaller than originally anticipated. There are quite a few other things to keep in mind in the overall site survey and network design but these are primary gotcha's post install.
