The Salt Lake Tribune has just put the top four cell carriers in Utah to the test, searching for the quickest network when you want to download music (or do other things).
Using six smartphones, The Tribune traveled to 114 random locations around Salt Lake County, from Bluffdale to Rose Park, to test the 3G and 4G networks of AT&T, Verizon, Sprint and T-Mobile.
See the interactive map (http://www.sltrib.com/sltrib/home3/53599322-200/network-speeds-mobile-verizon.html.csp) to see how well each network fared. By clicking on each dot on the map where The Tribune tested, readers can see the speeds for each carrier and service. There is also an intensity map that breaks down the results by network.
