The Federal Communications Commission yesterday announced new regulations for cell phone signal boosters.

Under the new rules, anyone who has a signal booster or plans to buy one must obtain permission to use it from their carrier. If permission is obtained, the signal booster must be registered with the carrier to ensure it meets specifications and all parties are aware of its use.

The FCC's rules, which were first brought to the floor in 2011, take aim at reducing interference with wireless networks. Signal boosters are designed to connect to cell phones to improve a connection with towers in … Read more

Staying ahead of the curve has been a hallmark of Lookout Mobile Security (download), one of the few Android-only security companies to gain a loyal fanbase on Google's mobile platform, and today they've released a major update.

The key feature improvements in the refreshed Android app are a new feature for tracking lost phones with low battery and a dialer-scanner to prevent Dialer app attacks like the one that reared its head in September. The threat was no mere digital crank call. Had you tapped the link and dialed the malicious number, it could remotely wipe your phone. … Read more

This Wednesday's top stories are sharing the love of data (but not the love of sharing data):

It began with Verizon, and now AT&T has joined the data-sharing movement. Starting in August, new AT&T customers will be signing up for "Mobile Share" plans. All have unlimited voice and text, but you pick how much data you need, and up to 10 devices can share from that bucket of data. Generally speaking, AT&T and Verizon's plan prices are pretty similar in the lower data tiers. Depending on your needs, one can … Read more

We have ceded our attempts to communicate with aliens far too often to Hollywood.

There, paunchy producers and pugnacious directors have portrayed aliens as scary, difficult people, not unlike certain recording artists and movie actors.

Now you have the chance to speak to aliens directly and offer a peace pipe, or at least a pipingly warm greeting.

For, as part of the National Geographic Channel's "Chasing UFOs" series, everyone is invited to reply to a message sent (maybe) by aliens.… Read more

If America's Wi-Fi routers could vote, they'd likely reelect President Obama by about 6 percentage points.

That's just one of the unprovable conclusions I reached after looking at some clever new research by OpenSignalMaps, an Android app that relies on its crowd of users to keep track of all kinds of wireless data signals around the world. The app has gathered a database of almost 75 million geolocated routers worldwide and OpenSignalMaps co-founder James Robinson decided to parse some of that data for sentiments toward the president after noticing how many nearby routers were expressing themselves politically. … Read more

I've listened to a lot of speakers over the past thirty-odd years, and I can tell you this, they're all imperfect.

No hi-fi or home theater sounds like live music, and not a single one of the most exalted high-end speakers has truly flat frequency response.

Of course, everyday speakers are less accurate, which is why just about every receiver sold today has a calibration system that corrects speaker anomalies and tames room acoustic problems.

That's all fine in theory, but most speaker calibration systems only change rather than improve the sound of a hi-fi or home theater. So I'm a bit of a skeptic about the benefits of this type of processing, but I finally heard a correction system that delivered the goods. It's the DEQX HDP-Express. I listened to it over a very high-end system (owned by DEQX's publicist).

The sonic transformation was at once subtle and dramatic. I first listened to the system without any correction, and the sound was excellent. The speakers were large floor-standing towers (Focal Utopias). I played a few recordings I know well, and the sound was beautifully balanced and natural.

Ah, but then my host switched on the DEQX speaker correction, and the sound of the "Wynton Marsalis & Eric Clapton Play the Blues" CD snapped into focus.… Read more

You might have already read that we're anticipating 4G phones and products dominating this year's CES.

That's why it comes as no surprise that companies are banking on some users wanting even more of a boost on their 4G network.

So far, at least two new cell phone signal boosters will be announced at CES 2012.

The first is from Wilson Electronics, which you may remember debuted its Sleek Cell Phone Signal Booster at last year's CES. The company also released a signal booster for the iPhone in 2009 called the iBooster.

This year, the company … Read more

The reported acquisition of Anobit should catapult Apple into the ranks of leading flash memory companies and mirrors what it has done with the A series of chips in its iPhone and iPad.

Apple is in the process of buying Anobit, an Israel-based flash memory firm, according to Israel's Calcalist business news site. The purchase price isn't small--in the range of $400 million to $500 million, according to reports.

So, what does a payout in that range bring to Apple? First of all, it's important to understand that Apple is not a flash memory neophyte, according to … Read more

For the most part Wi-Fi technology works quite well to keep your Mac, iPhone, and other devices connected; however, there are times when certain devices or setups may be plagued with Wi-Fi dropouts.

Recently I covered a number of approaches to fixing Wi-Fi dropout problems, though these only covered the configuration options in the router and the computer itself. Besides the system configuration, an cause for Wi-Fi drop-outs can also be poor Wi-Fi signal quality.

The quality for any analog signal, be it electrical, optical, or radio, can be determined by comparing the desired signal level to the background noise … Read more
