bacatcha, thanks for the documents
Based on reading T-Mobile-CCB pages 9-15 (Preliminary Statement pages 5-11), it looks like the definition of "pre-established vicinity range" is key. If the post Markman criteria for auto-switching ends up being based on / limited to "predetermined, fixed distance" and not on some permutation of signal strength / signal quality / signal-to-noise, I doubt I'll be counting my chickens before they hatch ... or ordering any premature manhattans ... with or without cherries.
