AT&T yet again the worst-rated carrier in U.S.

More bad news for AT&T.

Consumer Reports has released its annual carrier ratings. And just as it had in the last two years, AT&T landed in last place, far behind the top major carrier in the roundup, Verizon Wireless.

Verizon Wireless fared somewhat well in the study, earning relatively strong marks on voice and data. The only bright spot in AT&T's review was its 4G LTE network, which actually beat out its chief competitor in this year's study.

Sprint and T-Mobile USA landed between Verizon and AT&T.

FCC chair backs Dish Network as wireless carrier, but with a catch

The FCC's chairman has given his thumbs-up to Dish Network's desire to enter the wireless market. But Dish is none too happy with the restrictions proposed.

FCC Chairman Julius Genachowski said yesterday he would approve Dish's request to build its own 4G wireless network, the Washington Post reported. The federal agency, which opposed the proposed merger between AT&T and T-Mobile last year, wants to see more competition in the wireless industry.

"If approved, these actions will promote competition, investment, and innovation, and advance commission efforts to unleash spectrum for mobile broadband to help meet … Read more

NTSB tosses the BlackBerry in favor of the iPhone

Here's another signal that might be pointing to a BlackBerry swan song -- the U.S. National Transportation Safety Board is ditching the device for Apple's iPhone 5. This is the latest in a growing number of government agencies that have turned their backs on the mobile phone.

The government agency announced its plan in a government filing last week, according to Bloomberg. The reason it gave for dropping the phone is that it is not reliable.

BlackBerry devices have been "failing both at inopportune times and at an unacceptable rate," the NTSB wrote, according to … Read more

AT&T doubled its 4G LTE coverage this year

Striving to play catch-up with Verizon, AT&T has doubled the reach of its LTE network from a year ago.

The carrier's 4G LTE network now covers more than 150 million people across the U.S., double the number at the end of last year. With its rollout ahead of schedule, AT&T aims to reach 250 million people by the end of next year and 300 million by the end of 2014.

AT&T's LTE network is currently available in 103 markets scattered around the country. This week was another busy one for the … Read more

LTE networks vulnerable to inexpensive jamming technique

A laptop, an inexpensive transmitter, and a little technical knowledge is all that's necessary to take down the high-speed wireless data networks that are being embraced as the future of wireless communications, researchers warn.

As wireless consumers are increasingly doing more with their smartphones, demand for faster, persistent connections is also growing. Boasting speeds four times as fast as current 3G networks, long-term evolution (LTE) is being deployed across the country by every wireless carrier in the United States. Verizon, which was the first national carrier to launch LTE, expects to have the networks in 400 markets by the … Read more

Sinofsky: I never tried to take over Windows Phone division

Former Microsoft executive Steven Sinofsky has sounded off on claims that he tried to take over the company's Windows Phone and developer businesses.

Hal Berenson, president of True Mountain Group, a company that provides technology and management consulting, wrote in a blog post earlier this week that he'd heard from Microsoft employees that Windows chief Sinofsky was waging battles over the last several months to take control of the company's Windows Phone and Developer divisions. His actions were turned away by Microsoft CEO Steve Ballmer and other top executives, leading to his departure, Berenson claims.

Sinofsky rebutted … Read more

Sprint to offer landline-cutting device to its wireless providers

Sprint's Phone Connect device will now find its way to more people anxious to get rid of their landlines.

Known as Sprint Phone Connect, the "plug and play" device operates via Sprint's 3G network. Users can simply plug their home or office phones into the device, and calls are then carried over the network instead of the traditional landline.

Sprint already sells the product directly. But now the company is offering it to its MVNOs (mobile virtual network operators), wireless providers that buy network services from the major carriers and then sell them to customers. This … Read more

Verizon and HTC's latest twist: The $199 Droid DNA

Verizon and HTC unveiled a new device that the two hope will appeal to customers during the holiday season, while helping to reverse HTC's floundering fortunes.

The phone, the Droid DNA, sports a 5-inch screen, putting it more in the "phablet" category with Samsung's Galaxy Note. It runs on Android 4.1.1 Jelly Bean and includes a boatload of powerful features, including a Super LCD 3 display with 440 pixels per inch, capable of playing 1080p HD video.

HTC noted the screen rivals traditional HDTVs, while the pixel density is among the highest available on … Read more

U.S. city gets one of the world's fastest networks... for a week

This weekend and next week in Salt Lake City's Salt Palace Convention Center, there are likely to be more gigabits flying around, and at a faster amount per second, than just about anywhere else on the continent.

That's where a cadre of volunteers from top universities, government labs, and industry have put together a sort of dream network for this year's SC2012 Super Computing conference, beginning today in Utah. Using multiple 10 gigabit per second (Gbps) and 100Gbps circuits, SCinet links the convention center to other powerful networks around the world, including the Department of Energy's ESnet, Internet2, and National LambdaRail.… Read more
