VoIP over EV-DO Rev. A, the technology stack that effectively killed EV-DV, has been given Qualcomm's blessing this week, possibly clearing one of the last remaining roadblocks to Sprint and Verizon getting this show on the road. Of course, the big draw for VoIP over EV-DO is simultaneous voice and data, a feature where UMTS currently has EV-DO squarely beat. To get the seal of approval, Qualcomm went big with 62 simultaneous VoIP calls on a single channel in "mobile, pedestrian and fixed" environments. Picture sixty-two Verizon "Can you hear me now?" guys standing in the area of one city block, and you'll get the idea.
