Verizon Wireless said it will introduce its 3G service to 11 markets starting next week: In what appears to be a direct hit against Wi-Fi, Verizon also said it would launch its EV-DO service in 20 airports around the country. A recent report from TeleAnalytics showed that the use of Wi-Fi in airports has grown by more than 350 percent in a six-month period. It appears that Verizon is looking to capture a bit of that demand for wireless Internet access. However, its service still costs $80 a month while most Wi-Fi access charges are significantly less.
