The company I work for provides wireless internet connectivity via tower mounted AP's all over the county. We would like to include on our website a way for potential customers to input their address, and then see on a map whether or not they are within range of one of our towers. This would also be useful for us to find out if new customers who don't yet have an internet connection are within range before even doing a site survey. It does not have to involve an Google Maps API necessary, but something similar would be great. Does anyone know anything about this?
