Motorola Mobility chief Sanjay Jha during his time on stage at the Cable Show on Thursday downplayed the prospect that cellular data would kill cable Internet or TV anytime soon. In part referring to Comcast's gigabit cable demo at the same session, Jha didn't believe that every Internet need could be handled by cellular alone. Technologies like LTE-based 4G, which can hit 50Mbps peak in the real world, wouldn't have enough bandwidth to handle 1080p video or other very network-intense tasks.
