![]() And though our tests show that Sprint’s 4G WiMax service is marginally faster this year than last year, it’s still not in the same league as its rivals’ LTE services. Sprint’s 3G CDMA network has fared poorly in our study for the past two years. Photograph by Robert CardinSprint’s 3G and 4G services performed worse than any other carrier’s in our study. “It’s great to see the results of our 4G network strategy in PCWorld’s tests and in the feedback we’re getting from our customers.” “We made a decision to roll out ongoing upgrades and invest in our mobile network, on our way to more broadly deployed 4G LTE, so our customers could enjoy fast speeds and the best possible experience,” said John Donovan, AT&T’s vice president of technology and network operations. As a result, users won’t experience the dramatic and frustrating 3G-to-4G speed decreases that they would on other services.ĪT&T says it kept investing in its HSPA+ network to ensure a smooth transition to 4G LTE. ![]() When 4G service becomes unavailable on your AT&T 4G phone, the phone automatically switches over to AT&T’s HSPA+ network, which in our tests delivered snappy download speeds (2.62 mbps on average). Phones used in testing AT&T’s wireless services: Motorola Atrix 2 (left) for 3G, and HTC Vivid (right) for 4G.AT&T’s ace in the hole is its compelling pairing of 4G LTE service and 3G-equivalent HSPA+ service, which turned out to be the fastest combination offered by any carrier in our study. AT&T says 4G customers can expect download speeds of between 5 mbps and 12 mbps, and upload speeds of between 2 mbps and 5 mbps. AT&T says that it expects its LTE network to be complete by the end of 2013, at which point users should be able to get 4G service anywhere that AT&T offers its 3G service today. The AT&T LTE network, which launched in September of last year, is currently offered in 31 cities, far fewer than the 203 that Verizon’s LTE network serves. ![]()
