The city of Burbank in California is one of the many the cities in the U.S. that currently offer free WiFi service to residents and visitors. The downtown area has 12 access points and is expected to have nine more in the coming months. Getting a strong-enough signal, however, is very difficult, with the highest level, as per an assessment, reaching only 31 percent. This common problem has not deterred many other cities to go the wireless route. They believe free WiFi will attract customers and investments and therefore promote the growth of the local economy.
