LightSquared CEO Sanjiv Ahuja is taking his case for building another 4G network to the public.

Ahuja and LightSquared plan to publish an open letter in major newspapers tomorrow advocating the need for the company's planned 4G LTE network, which has come under fire over concerns that it interferes with critical GPS equipment. Over the past few months, the company has attempted to appease GPS companies, government officials, and regulators, by taking steps including using spectrum less likely to cause interference, starting up a program to address the issue in rural communities, and most recently unveiling a device that would solve the interference problem altogether. … Read more

Clearwire is in talks with a number of carriers, including AT&T and Verizon Wireless, about eventually providing wireless capacity with its planned 4G LTE network.

"We're talking to everybody," Clearwire Chief Executive Eric Prusch said in an interview with CNET today.

Prusch didn't specifically name the two, but only said the company was talking to multiple companies when asked about AT&T and Verizon. The company's decision to move to LTE, a more widely accepted standard of 4G used by other U.S. carriers, has helped spur new discussions.

"The level … Read more

Sprint is holding a special event in early October that it's dubbed "a strategy update," prompting speculation as to what strategy the carrier will discuss.

The invite sent out to the media says the event will take place in New York City on Friday, October 7, from 9:30 a.m. to 1 p.m. ET. But the agenda teases only presentations by senior management and a Q&A session with no details as to the topic.

So far, speculation is pointing to Sprint's 4G future as the potential subject.

Sprint CEO Dan Hesse apparently … Read more

Eleven years since its original inception, the Deus Ex series welcomes a new entry in the form of Deus Ex: Human Revolution. In a world where human augmentations have been commercialized by big business, human beings have the option to upgrade not just their bodies but also their minds. Such an ethical hot topic has created passionate factions on each side of the argument forcing players to find a balance between the two.

A franchise known for mixing RPG and action elements all while giving the player the freedom of choice, we've been anxiously awaiting to see just how such an ambitious collection of mechanics play out on current-generation consoles. Taking a special look at the game on PC is CNET Senior Editor Rich Brown.

Jeff: After just surviving a summer drought of games like the one we just experienced, Deus Ex: Human Revolution is a very welcome light at the end of the tunnel. It's an incredibly deep and layered game with a cerebral storyline that will charm even the most jaded cyberpunk enthusiast--a true complement to the game's great Blade Runner-inspired art direction.

The best way I can describe Human Revolution is a cross between Metal Gear Solid and Mass Effect. The team at Eidos Montreal borrowed the best elements from each of these franchises and made it their own, successfully weaving a game that lives up to its series' legacy of giving the player ultimate choice. This concept applies to almost everything Adam Jensen--the game's main character--does, from interrogating a person of interest to infiltrating a testing laboratory.… Read more

Mobile apps are still not secure when it comes to storing certain personal information, according to a new study from security firm ViaForensics.

Dissecting a variety of apps for Apple's iOS and Google's Android, ViaForensics found that 76 percent of them store user names in cleartext without encryption, while 10 percent store passwords in the same way, making such data more vulnerable. Running a series of tests from November 2010 through June 2011, the security firm checked out apps from several categories, including financial, social networking, productivity, and retail.

Each individual app received a pass, fail, or warn … Read more

Heartland Payment Systems, which processes payments across the country, is the latest company to jump on the mobile-payment bandwagon.

The Princeton, N.J.-based company said today that it was launching a system to allow merchants to accept payments through smartphones and tablets, similar to Square or Verifone. The system, called Mobuyle, includes an Android application and an encrypting reader that plugs into the device's audio hack, allowing stores to expand the number of point-of-sale terminals on the fly.

Heartland is one of many to be lured in by the opportunities that are emerging from the mobile-payments area. While … Read more

LAS VEGAS--Researchers at the Black Hat security conference today revealed two ways the Square payment system, which turns any iPhone, iPad or Android into a point-of-sale credit card processor, could be used for fraud.

Adam Laurie and Zac Franken, directors of Aperture Labs, discovered that they can transfer money from a stolen card into their bank account associated with Square without having to swipe a card through the Square dongle card reader. To do this, they used code written by Laurie that lets them feed magnetic stripe data from a stolen card into a microphone and convert it into a … Read more

AT&T and Verizon are working "behind the scenes" to stamp out new 4G wireless entrant LightSquared, according to billionaire hedge fund manager Philip Falcone.

Falcone, speaking to CNBC today, claimed the two telecommunications giants aren't competing fairly and are using their power to undermine LightSquared, which is run by Falcone's Harbinger Capital.

LightSquared is attempting to build a nationwide 4G LTE network that it will sell on a wholesale basis to other carriers that want to resell its services. But the company has run into a major hurdle with a coalition of companies reliant … Read more
