FCC Proposes $48,000 Fine To Man Jamming Cellphones On Florida Interstate

From the FCC"An individual who had been jamming cellphone traffic on interstate 4 in Florida was located by FCC agents with the assistance of Hillsborough County Sheriff's Deputies. The individual had reportedly been jamming cellphone traffic on I-4 for two years.

The FCC is now proposing a $48,000 fine for his actions. They say the jamming 'could and may have had disastrous consequences by precluding the use of cell phones to reach life-saving 9-1-1 services provided by police, ambulance, and fire departments.'"  

While the fine is large, it is not unprecedented: last August (2013) a New Jersey man named Gary Bojczak, who worked for a construction company in Northern New Jersey was fined $32K for an illegal GPS jamming device that disrupted the Newark airport system on multiple occasions.  The FAA and FCC spent two years (March 2009 to April 2011) locating the source of the jamming at Newark Airport.

Wireless jamming is considered to be more than an inconvenience or nuisance, and is treated as a significant threat since it can disrupt critical and emergency communications, terrestrial and satellite communication such as GPS tracking systems that are required for everything from aircraft, personal or vehicular location to systems requiring financial trading.  It can also potentially affect military operations.

As GPS can be negatively impacted over a wide area by a relatively small jammer, alternative technologies such as eLoran and MEMS (microelectromechanical systems) are being investigated as a secondary location signal provider.  This will only continue to be more critical as self driving vehicles, commercial drones and intelligent highway system usage continues to expand.

Despite “Framily” Push, Sprint Continues To Bleed Customers

As reported by GigaOm: In January, Sprint launched a major new campaign to lure in new mobile subscribers and keep old ones loyal, but the potential benefits of its “Framily” program didn't show up in its first quarter results. The company shed nearly 400,000 subscribers as it struggles to get its LTE network rolled out nationwide and faces off against mega-carriers AT&T and Verizon as well as a newly resurgent T-Mobile.

Sprint lost a net total of 231,000 postpaid subscribers (which includes contract and non-contract subscribers who aren’t on a pay-as-you-go plans) and 364,000 prepaid subscribers. The bright spot was a gain in 212,000 wholesale subscribers, reflecting Sprint’s growing business in connecting mobile virtual network operators (MVNOs) like Tracfone, FreedomPop, Ting and Republic Wireless. The revenue it brings in from an MVNO subscriber, however, is a fraction of what it sees from a customer who buys mobile service directly from Sprint.

Sprint executives blamed the subscriber loss on the tumult created by its ongoing network overhaul. Sprint isn't just trying to bring its LTE network coverage on par with its competitors, but it’s also rebuilding its 2G and 3G CDMA networks from scratch. Service disruptions caused by that upgrade work are causing disgruntled customers to leave, Sprint said.

Still, there are some glimmers of light at the end of this tunnel. Sprint’s LTE network now reaches 225 million people in 443 cities, so it’s within spitting distance of its mid-year goal of 250 million people covered. And while Framily didn't stem customer losses this quarter, nearly 3 million subscribers signed up for the new friends and family plan last quarter. That’s significant but those customers are not only more likely to stick with Sprint in the future, but they’re likely to recruit new subscribers into the Sprint fold.

Framily’s incentive structure offers an increasing discount as more people join a particular plan. Since Sprint will bill each subscriber separately, Sprint can use Framily to target customers outside of a traditional family plan. These customers aren't on contract, so they’re free to leave when they pay off their phone, but they’ll lose their accrued discounts. So if a “Framily” loses members it has a lot of incentive to replace them. At a separate event Tuesday, Sprint attempted to amplify the benefits of Framily by offering members discounts on Spotify’s subscription music streaming service.

Sprint now has 54.9 million total subscribers, making it half the size of AT&T and Verizon. It reported a first quarter net loss of $151 million, compared to a $643 million loss in Q1 of 2013, off of revenue of $8.88 billion.

Saudi Arabia Joins the Drone Arms Race

As reported by The Verge: Last week, Saudi Arabia bought its first drone fleet, according to a dispatch from Tactical Reports. Saudi Crown Prince Salman met with Chinese General Wang Guanzhong to sign a contract for a shipment of Chinese Wing Loong drones, also known as Pterodactyls. The drones that make up the shipment are designed to mimic America's Predator drone, with surveillance capabilities and enough lift to carry two matched air-to-ground missiles.

If the report is true, it means Saudi Arabia may have joined an exclusive club, one of the few nations with armed, unmanned aircraft. It's a group that, to date, includes just the US, Britain, Israel, China, and (depending who you ask) Iran — but beyond those countries, the capability is increasingly available to whoever can pay for it. At the Singapore Air Show earlier this year, both Israel and China were showing off their wares to would-be clients, including the Pterodactyl drone named in the report, and you could find similar displays at dozens of other air shows. With American counterterrorism efforts providing an ongoing test of how valuable the machines can be, there are lots of countries willing to buy.

The US is still responsible for the vast majority of drone strikes, but that may have more to do with politics than capability. A GAO report from 2012 found that more than 75 countries have some form of drone system. Most are unarmed but some, like the systems used in Australia, Japan, and Singapore, could be retrofitted for military purpose. More importantly, the US’ use of drones — more than 50 strikes in 2013 alone — seems to have whetted a global appetite for combat drones. "If you think of this as part of a broader trend of the proliferation of military robotics, then the idea that we were going to have a monopoly on this kind of technology was always a bit far-fetched," says University of Pennsylvania political scientist Michael Horowitz. "The American monopoly on drones is over and probably never really existed."

International trade barriers have slowed down the spread, but they haven’t stopped it. For US companies, combat drones are controlled under the same agreement as cruise missiles, through an association called the Missile Technology Control Regime. But China and Israel aren't part of the group, and the two countries have begun aggressively marketing drone systems to outsiders eager to keep up with US capabilities. One report from the consulting firm Frost & Sullivan estimated that Israel had exported $4.6 billion in drone systems between 2005 and 2012.

Experts also say Saudi Arabia has previously demonstrated both the interest and the budget for this kind of purchase. "Saudi Arabia and smaller countries like the UAE are trying to get their hands on whatever they can, and the US has pretty restrictive export policies," says Cornell University professor Sarah Kreps, who studies drone proliferation. The result leaves China as one of the only sources available in town.

One of the biggest questions is whether the new generation of foreign drones can match US capabilities. "We don't know at all about the quality of the pterodactyl," Kreps cautions, "these aren't combat-tested." Since unmanned aircraft rely so heavily on satellite and communications infrastructure, it’s hard to tell from the craft alone how well it will perform in the field. The Pterodactyl is also typically sold for a fraction of the price of the Predator, which has only fueled skepticism.

But even if China needs help to bring its drones up to US standards, that expertise may not be hard to find. UAVs are built on mostly commercial technology, drawing from the robotics and aviation industries. That’s much harder to keep under wraps than military tech like warheads or missiles. As long as there’s a market, there’ll be an incentive to build cheaper and more powerful drones, and the club of drone-armed countries will continue to grow. As Horowitz puts it, "What we know about the history of military technology suggests it will be really difficult to keep a lid on this."

Google’s Self-Driving Car Logs 700,000 Miles Navigating City Streets

As reported by GigaOm: Google says its self-driving car is now proficient at navigating the hazards of city driving.

In a blog post, Chris Urmson, director of the company’s self-driving car project, wrote that the Google cars have successfully completed 700,000 miles of city driving — around Google’s Mountain View, California headquarters — without incident:
“We’ve improved our software so it can detect hundreds of distinct objects simultaneously — pedestrians, buses, a stop sign held up by a crossing guard, or a cyclist making gestures that indicate a possible turn. A self-driving vehicle can pay attention to all of these things in a way that a human physically can’t — and it never gets tired or distracted.”
As of the last status update in August, the cars had completed 300,000 miles of service without an accident, at least under computer control — an actual person also sits in the car — but those miles were logged in a variety of conditions. Now Google seems to have doubled down on city driving, which presents more variable conditions than highway driving.

While this post is interesting, the comments are even more intriguing. One commenter predicted an increase in unsafe driving practices by human drivers who will now be tempted to cut off the Google cars, if they’re so darned accurate. Another requested  an “On-Board Missile Launcher” option, perhaps to deter or punish such cutoffs and counter road rage.

While negotiating Mountain View roads may be tricky, Google needs talk to me after the cars have mastered the potholes, rotaries and creative drivers of Boston. Now that would really be something.

Developing A Self-Cleaning Car Finish Using Nanotechnology

As reported by Tech TimesDrivers may soon be able to put away their buckets and cleaning rags after Nissan announced that it has developed a car that can clean itself instantly using a special kind of paint.  

Engineers at Nissan's European Technical Center in Bedfordshire, England applied a "super-hydrophobic" and "lipophobic" paint finish called Ultra-Ever Dry, which was developed and patented by UltraTech International, on the new Nissan Note supermini. The ultra-resistant paint can repel water and oils, as well as dirt, dust, mud and grit.

Although Ultra-Ever Dry has been used in other fields, Nissan claims that this is the first application of the special paint on automotive bodywork.
The paint uses nanotechnology to create a thin air shield above the surface of the car that makes rain, road spray, frost, sleet and standing water roll off the car without tainting its surface at all.
"By creating a protective layer of air between the paint and environment, it effectively stops standing water and road spray from creating dirty marks on the car's surface," explains Nissan in a press release.
So far, initial tests conducted on the self-cleaning Note were effective. Nissan engineers used Ultra-Ever Dry to paint one side of the car and regular paint on the other side. A video below shows how the side of the Note coated with Ultra-Ever Dry did not accumulate mud or dirt.
"The Nissan Note has been carefully engineered to take the stress out of customer driving, and Nissan's engineers are constantly thinking of new ways to make families' lives easier," says Nissan chief marketing manager Geraldine Ingham.
"We are committed to addressing everyday problems our customers face and will always consider testing exciting, cutting edge technology like this incredible coating application," she continues.
Nissan says it has no plans of making the special paint job a standard on factory models. It will, however, consider offering the self-cleaning paint as an aftermarket option. The company also promised to continue testing the technology in its European testing center.
This is not the first time Nissan introduced a self-cleaning function. The company has already developed a smart rear-view mirror that provides a better back view using a camera piped on the rear windshield. This camera is equipped with its own "wash and dry" function that uses water and air to keep the lens free from dust and dirt, allowing the driver a clear view of what's behind the car at all times.

Scale Is Increasingly The Name Of The Game In Cloud Computing

As reported by GigaOm: Resistance to cloud computing might not be futile, but it’s at least beginning to look foolish — especially as services from the top providers such as Amazon Web Services keep getting cheaper while their performance gets better. It’s also looking like smaller-scale or “enterprise” cloud platforms will have to promise some serious differentiation in order to justify their higher costs.

To highlight this trend, here’s a chart from publishing analytics startup Parse.ly graphing its IT spending from inception until early 2014.


The long story made short — you can read the whole thing up through September 2013 here — is that Parse.ly started off using Rackspace primarily and AWS for backup and a variety of ad hoc workloads (e.g., Hadoop jobs). In 2012, it opted to cut costs by switching its primary analytic database to physical servers in a co-location center while continuing to run its cloud workloads primarily in Rackspace. In late 2013, it began transitioning more workloads to AWS and completed an entire transition to AWS in late February 2014.

After paying double (to both Rackspace and AWS) during the transition, Parse.ly is now paying less than monthly than it was before making the move. Its spending patterns might be unique because of the workloads it’s running, but they’re compelling nonetheless.

And, Parse.ly Co-founder and CTO Andrew Montalenti told me, there’s icing on this cake, as well: “What’s crazy is we got a speed-up and saved money.” The company’s primary analytics database is now running significantly faster on AWS SSD-backed instances than it did on bare metal (albeit hard-disk-backed) servers.

If recent claims from Google about adjusting its pricing in accordance with Moore’s Law come true — and if its unique strategy around price reductions on long-running instances catches on — we should be in for continually lower prices on basic cloud computing services. AWS is the cloud king, but Google and Microsoft are positioned as strong contenders, and if low costs are what wins users, they’ll all play along to ensure no one else owns that story. The same goes for improved performance and rapid feature updates.

More and more, it looks like the future of cloud computing will be renting the infrastructure that lets users operate like, well, Amazon, Google and Microsoft but at a fraction of the cost (and scale). We’ll hear a lot more about where the industry is heading at the Structure conference, which takes place June 18 and 19 in San Francisco, and features, among many others, Google’s Urs Hölzle, Amazon’s Werner Vogels and Microsoft’s Scott Guthrie.

T-Mobile Has Started Building A More Resilient LTE Network

As reported by GigaOm: T-Mobile has begun upgrading its LTE network with a new kind of antenna technology that will help fix one of the biggest problems in mobile: the inconsistent signals and connection speeds our phones see as we move through the mobile network.

Anyone who has ever had five bars and a rocking data link to the tower, only to lose it 20 yards later, can attest to this. But starting in Chicago, Dallas and San Antonio, T-Mobile users will soon see those peaks and valleys become plateaus.

The technology is called 4-by-2 multiple input-multiple output, or 4×2 MIMO. You may already be familiar with MIMO if you’re familiar with how LTE or Wi-Fi works: multiple antennas send multiple parallel transmissions from the transmitter to the device. While nearly all LTE systems today use 2×2 MIMO — two antennas at the tower connecting to two antennas in the phone — T-Mobile is doubling up on spatial streams being transmitted over the network.

What that means is that there will be a lot more signals flying at your T-Mobile 4G phone, tablet or mobile hotspot, ensuring you can get a better downlink connection even if you’re at the fringes of the network or their obstacles between you and the tower. The biggest benefits will be on the return trip, though. With more antennas at the tower to pick up your phone’s generally weaker signals, you’ll get a big boost in your uplink connection.

Gigaom first got the scoop on T-Mobile’s plans last June, when one of its vendors Nokia Solutions and Networks confirmed to me T-Mobile planned on deploying the antenna array technology. At the time, T-Mobile wouldn’t even acknowledge that it was using 4×2 MIMO, but this week T-Mo VP of Technology Mark McDiarmid confirmed to me that T-Mobile is in the process of rolling it out in multiple cities across its network this year as part of a larger LTE upgrade.

“We do see the benefits 4×2 MIMO offers and will be deploying this in many cities in 2014 as part of our Wideband LTE rollout,” McDiarmid said in a statement to Gigaom. “All of T-Mobile’s available devices currently support 4×2 MIMO and we’ll ensure that new devices will as well. We believe this will be one of the first deployments by a top carrier network in the US.”

Sprint is performing trials of a similar technology called 8T8R, which actually creates eight transmit paths as opposed to T-Mobile’s four, and will incorporate it into future upgrades to its new tri-band Spark network.

Historically T-Mobile has always trailed its competitors when it comes to launching new generations of network technologies. It was the last to get 3G and the last to start rolling out LTE, but once it had gotten started it took advantage of its newer network equipment to surpass its rivals. It built the fastest 3G network in the U.S. in 2011, and with 4×2 MIMO its now among the pioneers in one of the latest advancements in 4G networking.

T-Mobile wouldn’t offer any details as to where the network is now live, but Gigaom’s favorite network tracker Milan Milanovic found evidence of 4×2 in the wild in Chicago, Dallas and San Antonio by polling fellow network testers on Howard Forums. This screenshot supplied by forums user besweeet shows iPhone in engineering mode in San Antonio with the arrow indicating four transmit signals from the tower.

What does this mean to me?

So if you’re a T-Mobile subscriber with an LTE handset, 4×2 MIMO basically means you’re going to get a more resilient connection as you move throughout the network. You won’t actually see your peak speeds improve, but you’ll be able to maintain a fast, consistent connection far more often, even when the network starts getting crowded.

According to Nokia networks’ Head of Technology for North America Petri Hautakangas, at the cell edge – those fringe areas of the network where your connection often suffers the most — you could see a 50 percent to 60 percent boost in download speeds and as much as 100 percent increase in upload speeds.

That boost provides a lot of advantages to T-Mobile as well as its customers. By connecting more customers throughout its network with faster speeds it increases its overall data capacity considerably, meaning it will take a lot more traffic to make its network congested.

As for where the network heads next, the location of the three sightings we've had so far provides a hint. They’re all Nokia-built networks. Nokia’s systems are concentrated in the interior of the U.S. Ericsson holds T-Mobile’s contract for most east and west coast cities. If Nokia has the jump on Ericsson for this new technology, then it might take a while before it arrives in New York or San Francisco.

In any case, this technology is an important step for mobile networking, demonstrating the subtle shift away from building faster networks, to building better networks. The 5-10 Mbps speeds we typically see on a smartphone today is plenty fast. But providing a consistent 5-10 Mbps connection no matter where you go in the network? That’s where the mobile industry should be heading.
