Three of the four major carriers in the U.S. have launched 4G. Out of those three T-Mobile has been stressing the fact that they have the worlds fastest 4G network in their recent commercials and press releases. There is no better way to prove the speeds then putting the networks against each other in a real world, non theoretical test.
Wilson Rothman of MSNBC did just that. Since Verizon hasnt launched a 4G smartphone yet, they couldnt be included. That leaves T-Mobile, AT&T and Sprint. Smartphones involved in the test were Samsungs Galaxy S 4G and myTouch 4G from T-Mobile. The Apple iPhone 4 (just for fun) and HTC Inspire from AT&T. For Sprint the HTC EVO was chosen.
The tests were a measurement of megabits per second. The end result of the tests proved that T-Mobiles Galaxy S 4G shined. As for the other devices and networks it was pretty close between the HTC EVO from Sprint and the HTC Inspire from AT&T, but holding its own against these 4G enabled devices was Apples iPhone 4 on AT&T which wasnt too far behind.
Following is the MSNBC video showing the speed test.
