Wi-Fi rides to wireless networks' rescue

Good old Wi-Fi could be the fix to an impending explosion of data on wireless networks.

Nearly three years after Apple introduced the game-changing iPhone, wireless operators around the globe are feeling the effects of the wireless data tsunami that is well under way. Even networks that don't support the iPhone are feeling the pinch as a generation of new wireless devices offering bandwidth-hungry Web applications are hitting networks. The result, as many iPhone users in New York City and San Francisco will tell you, is a network that drops calls and offers wireless Net surfing at the speed of a turtle. Savvy smartphone subscribers with Wi-Fi-enabled devices have already been seeking out Wi-Fi hotspots for their Internet surfing, music-streaming, and video watching. But as more devices, such as the Apple iPad come online and the forecast for wireless data shoots through the roof, wireless operators are looking at Wi-Fi as a way to offload some data traffic from their overburdened 3G networks. And as wireless data is expected to continue to grow rapidly over the next several years, they're looking at Wi-Fi as a part of their long term wireless strategies as well, even as they build out 4G wireless networks.
