In an interesting move, Silicon Valley's Mineta San Jose International Airport adds free on top of paid Wi-Fi: The authority decided to put out $90K for equipment and foot a $41K per year bill for service with 15 Mbps backhaul to handle what they believe will be 1,000 daily users. Oddly, T-Mobile and Wayport will also continue to operate for-fee networks that pass along $139K in revenue to the airport. The free service will be advertising supported. Several companies are working with the airport on providing advertising. Copyright
