Over the past few years I have noticed that the FAA has started to take down the large microwave towers at various en-route centers across the country. With everything going over fiber optic lines these days any idea what these microwave towers were used for. After looking at google street views seems like not all the microwave towers were removed at all the centers for example Miami, Atlanta, Washington, as of July 2018 New York still had their 3 towers. Wouldn't it make sense to have some sort of microwave backup just in case the fiber lines get cut by mistake?
