Ok, let's explain better the behind the scenes of the decision to answer both questions: We are designing coverage with the following criteria: -b/g everywhere with PDA/Iphone in mind (we already have 250 Iphones registered on campus, if there is one device that will take advantage of uninterrupted roaming it's the Iphone!) -n at 5 Ghz should be a good fit for a b/g coverage -no consideration for a Philippe -- On Fri, 9 May 2008, Chad Frisby wrote: In addition - even the purpose built VoWi-Fi handsets (Polycom, Cisco, etc.) are physically larger that iphone and much time is spent designing antenna's to improve their functionality and RX sensitivity.

Guys - Quite frankly - I am just gitty that there is a discussion on here that does not revolve around the configuration, debug, and hair pulling of Cisco WLAN.

I hear you -- but I really appreciate hearing everyone gripe (and it is an issues forum after all). So how do we go about getting Cisco to hear all this good stuff?
