What IT needs to know about near-field communications


The rise of near-field communications (NFC) has been part of the discussion in the mobile industry for years. Unfortunately, the technology hasn't generated much more than discussion to this point.
So far, all who have predicted the ubiquity of the point-to-point communications technology have been wrong. Executives at major tech companies - Apple and eBay, for example - have scoffed at the idea of NFC as an everyday tool, and consumers in general still have no idea what it is.
Regardless, the technology provides ample opportunity for businesses, and is still expected to make a slow climb to relevance over the next few years. With separate factors helping to drive growth of the technology into new markets, it's time to consider how NFC can help in the enterprise.

Apple makes good on CEO's promise to expand iPhone 5's 4G carriers


iOS 6.1 patches more than two-dozen security vulnerabilities and adds three-dozen LTE carriers to the supported list for the iPhone 5. Apple today released iOS 6.1, the first major update for the mobile operating system since its September 2012 launch, patching 27 security vulnerabilities and adding three dozen LTE carriers to the iPhone 5's support list.
At the top of Apple's list of improvements was an expansion of the LTE networks compatible with the iPhone 5, a move announced last week by CEO Tim Cook during a quarterly earnings call with Wall Street analysts.
"Next week, we are adding 36 more carriers for LTE support," Cook said Jan. 23. "And these carriers will be in countries that were currently not supporting LTE."
Among the iPhone 5 markets where customers now can connect to an LTE carrier are Denmark, Finland, Greece, Italy, Kuwait, Saudi Arabia, Switzerland and South Africa.
iOS 6.1 also added carriers in countries already served by LTE. In the U.S., for example, the update expanded the list from AT&T, Sprint and Verizon to add Alaska Communications, Bluegrass Cellular and Pioneer Cellular.
complete list of all iOS 6.1-supported LTE carriers can be found on Apple's website.
Other enhancements in iOS 6.1, according to Apple's typically terse note, included Fandango movie ticket purchases using Siri (U.S. only) and individual track downloads from iCloud for iTunes Match subscribers.
iTunes Match is the $25-per-year service launched in November 2011 that acts like a music storage locker in the sky, storing tracks purchased via iTunes or ripped from CDs in iCloud, then making the library available on all of a user's iOS, OS X and Windows devices.
Prior to today's update, iTunes Match automatically downloaded all tracks in an album, making it difficult to grab just a single tune to place, say, on a storage space-strapped iPhone.
iOS 6.1 also included patches for 27 security vulnerabilities, most of them labeled with the phrase "arbitrary code execution," Apple's way of saying they are critical.
Of the 27 total, 22 were in WebKit, the browser engine that powers Safari in iOS and OS X, as well as Google's Chrome. Not surprisingly, most were reported to the WebKit open-source project, and from that to Apple, by Google security engineers.
Eleven of the WebKit bugs were uncovered by the prolific Abhishek Arya, a Google engineer who goes by the nickname "Inferno."
The update also revoked several digital certificates improperly issued in mid-2011 by TurkTrust, a Turkish "certificate authority," or CA. While Google, Microsoft and Mozilla had previously revoked those same certificates, this was Apple's first move. It has yet to update Safari for OS X to do the same.
Today's update was the third for iOS 6, although the first two were minor refreshes that either fixed a handful of security flaws (November's iOS 6.0.1) or addressed a single issue ( December's iOS 6.0.2).
Owners of the iPhone 3GS, iPhone 4, iPhone 4S and iPhone 5; iPad 2, third- and fourth-generation iPad, and iPad Mini; and iPod Touch fourth-generation and later can retrieve 6.1 over the air by tapping the "Settings" icon, then the "General" tab, and finally "Software Update."

'Make me Asian' app yanked from Google Play amidst racism concerns


An app called "Make me Asian" that added details like narrowed eyes and conical hats to screenshots of users has been pulled from the Google Play store after inciting widespread public outrage, including a Change.org petition that was signed by more than 8,400 supporters.
"Make me Asian," along with the similarly offensive "Make me Indian," which featured things like feathers and war paint, are gone as of today. Their creator was listed as KimberyDeiss, who apparently had a large number of "Make me ..." apps on the Play store, according to AppBrain. That developer page appears to be down as well.
Peter Chin, a Washington, D.C., pastor and the organizer of the Change.org petition, celebrated the deletion of the apps, telling NPR, "I am deeply thankful to those who realized the danger of these stereotypes entering the mainstream and spoke out against this app, [b]ut I am also appreciative of Google, who listened to our concerns and acted accordingly."
However, it took some time before Google acted in this case -- Chin first blogged about the app in mid-November, and the intervening months saw a Twitter campaign and the aforementioned petition have no effect on the Play store until today.
Somewhat strangely an avowedly progressive company, Google has been at the center of the occasional sociopolitical controversy of late. Iris, the Android platform's ostensible answer to Apple's Siri, was hammered for early versions that provided stridently right-wing answers to some queries in early 2012. That, of course, was after Siri itself came under fire from pro-choice activists for apparently being hesitant to direct users to Planned Parenthood locations. (For the record, both apps have been updated to be less controversial.)

The 4G ad wars: Evaluating AT&T and Verizon Wireless


Wireless carriers are battling in print, TV and Web commercials that focus on having the biggest 4G network or the most 4G coverage. All these commercials create a phony issue that doesn't relate to the actual reasons for choosing 4G service or choosing a given carrier to provide it.
We looked at two TV ads, from AT&T and Verizon Wireless, posted on their YouTube accounts.
The AT&T commercial consists of nearly 30 seconds of listening to the monotonous guitar hammering of "Memory Lane" by Eddy Current Suppression Ring and watching a young Dude appearing in about 40 different locations, with not quite that many girls, and with his trusty AT&T smartphone. He talks, laughs, smiles, walks, lies on a beach, looks at stuff, texts, takes photos of himself with one or another of the girls, and stuff like that.
At the end, and 30 seconds rarely has felt so long, the voice-over says, "AT&T. The nation's largest 4G network, covering 2,000 more 4G cities than Verizon."
Or as the YouTube text helpfully elaborates, "This spot follows our main character as he uses his AT&T smartphone throughout his adventures across the states. He chronicles his travels and shares his memories and experiences with the people he cares about thanks to AT&T, the nation's largest 4G network."
The concept of the "nation's largest 4G network" is a key message for AT&T. The carrier arrives at "largest" by adding together cities covered by two different cellular technologies, both of which AT&T labels 4G: LTE, in 103 cities at this writing, and HSPA+, which covers a whole lot more.
AT&T's website distinguishes between the two. 4G LTE represents the "fastest mobile Internet speeds," whereas "4G Mobile Broadband" is the carrier's "4G HSPA+ network with enhanced backhaul. AT&T's 4G HSPA+ network is capable of delivering 4G speeds when combined with enhanced backhaul."
Apparently our Dude in the TV commercial is On the Road, an epic journey of exploration and discovery. Who is this guy? He's young. A casual dresser. He laughs a lot. His one obvious flaw is that he favors clear plastic parasols on rainy days. Perhaps he's a successful high-tech entrepreneur who's cashed out on some esoteric Web technology and retired at what looks like about 26 or so, and with time to kill and money to spend, decides to have adventures across the states. All 50 of them it seems. Maybe he's decided to visit the "2,000 more 4G cities than Verizon" that AT&T covers with the nation's largest 4G network.
Verizon Wireless takes a less impressionistic approach: It focuses on, you know, facts. This commercial, called "Easy Choice," opens with the headline "4G LTE Focus Group," so we know the people we're about to see are "real" people.
It's a conference room, clean, well-ordered, spare. The Focus Group Guy (FGG) begins helpfully by telling us that 4G LTE "has the fastest speeds."
"So, let's talk about coverage," he says, getting right to The Point. We see an easel with a bar chart, labeled "U.S. Markets with 4G LTE Coverage." A humongous red bar -- Verizon! -- rears up from the x coordinate, towering above the shrimpy little LTE bars for AT&T, and Sprint and poor T-Mobile.
"Based on this chart, who would you choose?" he asks the focus group. And they are wowed, stunned, impressed. Eventually, they all agree that they'd choose Verizon. The voice-over, as the words "It's an easy choice" appear on screen: "It doesn't matter how you present it. Verizon. More 4G LTE coverage than all other networks combined."
But what are these people "choosing" Verizon for? The FGG's question is ambiguous. He could be asking, "Based on this chart, which carrier would you choose as having the most LTE sites?" In that case, it's a simple matter of counting, and currently Verizon does indeed have the largest number of LTE cities. But he could also be asking, and this clearly seems to be the implication of the commercial, "Based on this chart, which carrier would you choose as your LTE provider?"
Both AT&T and Verizon are trying to persuade people that having a lot of LTE or 4G base stations somehow makes for a superior or better network, and therefore becomes a reason, or even the reason, for choosing the carrier. But you'd have to be as peripatetic as AT&T's Dude before a nationwide network of Verizon LTE base stations actually becomes a tangible benefit.
About one mile from where I live there's a main drag with a McDonald's, a Burger King and a Mexican restaurant that's part of a small Massachusetts chain. Based on the number of fast food restaurants owned by McDonald's, Burger King and this Massachusetts restaurant chain, which would you choose?
The answer is: The number doesn't have any bearing on my choice. I don't care if McDonald's has eleventy zillion stores in 50 states. I only care if it's got one where I live. And if I want TexMex instead of a Big Mac, I don't care even if there is a McDonald's where I live.
Consumer Reports, while not the last word on cellular service and phones, lists a "reader score" of overall satisfaction with their cellular service and then a set of criteria that CR's experts created for measuring specific features or attributes. "Voice and texting scores are relative (reflecting differences from the average of all providers)." It then goes on to give mean scores on a scale of "Very poor" to "Excellent" for: "value for money, satisfaction with data service, ease and speed of reaching support staff through the phone system, and support staff knowledge. Issue resolved ratings are relative as well."
There's no rating of coverage, reflecting the fact the total number of LTE or 4G cities served by a carrier is simply not a criteria for buying a particular phone or choosing a particular provider. In fact, the major wireless carriers in CR's most recent ratings scored well below much smaller providers, which often make use of one of the major's wireless network and may focus only on a given region.
CR concludes: "On the whole, readers who prepaid for their service (without a contract, for monthly minutes, unlimited or pay-as-you-go) were more satisfied overall than respondents with standard service. Customers at prepaid carriers were also happier with the value for money of their service."
Data speeds, the latest network technology, are only one part, and apparently often not the biggest part, in customer satisfaction with wireless service. TV commercials that focus on the number of cities covered by a 4G service simply try to deflect attention from more substantive and more relevant issues.
