Mobile data cards will kill off wi-fi hotspots

3G could potentially kill off wi-fi, according to analysts Infonetics Research, as more and more of us use mobile broadband data cards rather than the wireless hotspots provided by coffee shops and the like as the service becomes “more available, more affordable, and a higher performance choice”

Infonetics says that sales of mobile data cards will nearly quadruple between 2007 and 2011, hitting $2.9 billion. The analysts predict adoption will be driven by lower mobile broadband prices resulting from the launch of HSDPA networks. The report also says that worldwide mobile data subscribers will reach 144 million by 2011.

Anyone who’s used a mobile data card knows they’re a lifesaver. I wouldn’t be surprised if before long mobile data subscriptions are the de facto connectivity for anyone taking their laptop outside their house.
