All, I need your help.  It's generally accepted that there are functional differences between Photon and Jedi radios where the older Photon radios will exhibit a higher degree of roaming efficiiency and stability compared to the Jedi radio. We now have some customer situations where they're comparing, side-by-side, devices with Photon radios and devices with Jedi radios and are seeing these differences.  The customer "thinks" that, at a minimum, there should be no degradation in performance from one radio to the other and they'd almost expect performance to improve with a newer radio. Has anyone given their customers a valid explanation to this phenomenon other than "that's just the way it is"?  I'd appreciate any feedback you have. Thanks in advance, Tom
