SignalMapA service that I came across today called SignalMap left me wondering "now why didn’t I think of that?" Whenever you buy a cellphone the one thing that you’re always wondering is what the service be like in the places you’re at everyday (work, home, etc…). You’re just never sure if there will be good reception, or even a signal for that matter.

So what does SignalMap do? It gives users a central place to input their cellphone signal, along with what carrier and cellphone they are using. This information will be placed on a map for everyone to view and benefit from, and from the looks of it SignalMap has a good start.

When looking at one of the maps there are several different icons that you will see. Red icons correspond to the Verizon network, blue are AT&T, pink are T-Mobile, and yellow represents Sprint. Each of the icons demonstrates how strong a signal is by the corresponding number of bars, and if there is a skull that means it is a dead spot (no signal available there).


They do limit you to viewing 100 signals on the map at one time, and they will tell you what the average signal is for the area that your viewing as well as the number of dead spots. As of right now the number of submissions by users isn’t the greatest, but if we all add our information to the map it will help the service become even better. And no, it isn’t difficult to do. All you have to do is drag a marker to the spot on the map that you want, and then add the corresponding information:


I really hope that this service continues to grow, which is one of the reasons I wanted to write about it. It would be really cool if there was some application that you could put on your phone so that you could upload the information to their servers in a single click, but I think they’ve made it about as easy as they could without doing that.
