IEEE revises 802.11 standard

IEEE 802.11-2012 is the fourth revision of the standard to be released since its initial publication in 1997

IEEE announced the publication of IEEE 802.11-2012 standard, which defines the technology for wireless local area network (LAN) products. IEEE 802.11-2012 is the fourth revision of the standard to be released since its initial publication in 1997. In addition to incorporating various technical updates and enhancements, IEEE 802.11-2012 consolidates 10 amendments to the base standard that were approved since IEEE 802.11’s last full revision, in 2007. IEEE 802.11n, for example, defined MAC and PHY modifications to enable much higher throughputs, with a maximum of 600Mb/s; other amendments that have been incorporated into IEEE 802.11-2012 addressed direct-link setup, “fast roam,”radio resource measurement, operation in the 3650-3700MHz band, vehicular environments, mesh networking, security, broadcast/multicast and unicast data delivery, interworking with external networks and network management. “The new IEEE 802.11 release is the product of an evolutionary process that has played out over five years and drawn on the expertise and efforts of hundreds of participants worldwide. More than 300 voters from a sweeping cross-section of global industry contributed to the new standard, which has roughly doubled in size since its last published revision,” said Bruce Kraemer, chair of the IEEE 802.11 working group. The new IEEE 802.11-2012 now supports devices and networks that are faster, secure, and also provide improved cellular network hand-off, says a release. IEEE 802.11 standards, often referred to as Wi-Fi, already underpin wireless networking applications around the world, such as wireless access to the Internet from offices, homes, airports, hotels, restaurants, trains and aircraft around the world. IEEE 802.11defines one MAC and several PHY specifications for wireless connectivity for fixed, portable and mobile stations.

Social media stress? There’s an app for that

Nestle, purveyor of the decades-old KitKat snack, has launched an app it says addresses a growing problem among young social media users — giving them a break from the stress of posting updates by doing it for them. The software, Social Break, automatically sends random updates to users’ Facebook, Twitter and LinkedIn accounts. It will be officially launched in Singapore later this week and is free to download from While the application is a tongue-in-cheek marketing gimmick, the developers behind the software, ad agency JWT, say it also highlights a serious problem among younger users, especially in Asia: growing stress about time spent maintaining a presence on social networks. JWT surveyed 900 among 19-26 year-olds in China, Singapore and the United States and found that more than half considered it too time-consuming to keep up with all their social media commitments and conceded that the time they spent on such sites had a negative impact on their job or studies. JWT says that their survey shows that young people feel under increasing pressure to maintain their social media connections, responding to friends’ requests to comment on or “like” their posts, photographs or other updates.

Nearly two thirds of Chinese surveyed said they felt pressure to be in constant contact on social media, with 58 per cent saying their social media obligations caused them stress. “Social media used to be fun. It shouldn’t be an obligation, it shouldn’t be another life we have to maintain,” says Valerie Cheng, executive creative director of JWT’s Singapore, which was hired by Nestle to develop the app. Asia is home to some of the biggest social media populations in the world. Socialbakers, a service which monitors usage, lists Indonesia, India and the Philippines among the top 10 countries on Facebook. Nearly 57 per cent of Singapore’s population is on Facebook. A survey published by consultants McKinsey last month found that China has by far the world’s most active social media population, with 91 per cent of respondents saying they visited a social media site in the previous six months, compared with 30 per cent in Japan and 67 per cent in the United States.

Random response

Users of the KitKat app can enter account details for Twitter, LinkedIn and Facebook and then choose how frequently they want the software to send updates. It will then respond to items where the user has been tagged with one of eight random messages. LinkedIn will occasionally forward links posted by other users, while Twitter will respond randomly to messages from other users. “We found that the reason young people need breaks is because of their social media responsibilities, but that’s exactly what they do when they’re on a break,” said Lydia Daly, JWT planning director. “It’s a vicious circle.” JWT acknowledged the app may not find favour with Facebook. Cheng pointed to an app launched by fast-food chain Burger King in 2009 which, she said, had a similarly irreverent attitude towards one’s social media network – calling on users to delete friends in return for free burgers. Facebook disabled the app, saying it violated its privacy policy. JWT says that if the Social Break app is a success they hope to adapt it to work on China’s homegrown social networks and, in the long run, introduce elements of artificial intelligence into automated responses. For now, said Daly, the most important thing was to avoid causing offence or embarrassment with inappropriate responses, such as posting something flippant to news that a friend’s grandfather had died.

Many Facebook users unaware of privacy risks: report

Many users of Facebook are unaware of the privacy risks from the massive social network site or fail to take adequate precautions, a report by Consumers Reports says. The report found nearly 13 million U.S. Facebook users do not use, or are not aware of the site’s privacy controls. An estimated 4.8 million Americans have posted about where they planned to go on a certain day—a potential tip-off to burglars, the report noted. And it found that 4.7 million have “liked” a Facebook page about health conditions or treatments, details that insurers might use against them. The report, part of the nonprofit group’s State of the Net survey, estimated that seven million households using Facebook said they had trouble last year, ranging from someone using their log-in without permission to being harassed or threatened. That was up 30% from the previous year. Only 37% of Facebook users said they have used the site’s privacy tools to customize how much information is shared with third parties, according to the Consumer Reports survey.

“Facebook really is changing the way the world socially communicates and has become a successful service in part by leveraging copious amounts of personal data that can be spread far wider than its users might realize,” said Jeff Fox, Consumer Reports technology editor. “Our investigation revealed some fascinating, and some disquieting trends—but ones always worth knowing for consumers who wish to keep their personal data under better control.” The report indicates Facebook gathers a considerable amount of information from users that they may not be aware of. “Some users might be surprised to know that Facebook gets a report every time they visit a site with a ‘Like’ button, regardless of whether or not they click on that button, have a Facebook account, or are even logged in,” the organization said. It did give credit to Facebook for taking privacy and security “seriously” by implementing checks against abuses and inappropriate applications. But Consumer Reports said Facebook should do more by fixing “a security lapse” that permits users to set up weak passwords including some six-letter dictionary words and to help users avoid inadvertently sharing status updates with the public.

Consumer Reports points out that all of this data collection is not without risks. The report was based on a survey from Jan 16-31 of a sample of 2,002 people. In a statement, Facebook said it works to help protect the safety and privacy of its users. “We believe more than 900 million consumers have voluntarily decided to share and connect on Facebook because we provide them options and tools that place them in control of their information and experience,” the company said. “As part of our effort to empower and educate consumers, we always welcome constructive conversations about online privacy and safety.” The number of people using Facebook worldwide had risen to 901 million by the end of the quarter, according to company documents. Facebook is expected to make its much-anticipated stock market debut in the coming weeks in a public offering which could raise as much as $10 billion, the largest flotation ever by an Internet company on Wall Street.

Hacking Android devices: What to worry about

It’s not just malicious apps you need to be wary of infecting your smartphone. Now, navigating to poisoned websites are a threat, too. Security researchers have discovered a new malware targeting Android devices that doesn’t take the usual route of embedding itself in an app. The malware, dubbed “Not Compatible,” is instead tucked into websites that try to push the malware onto visitors’ devices, representing a dangerous new technique by hackers to try and access personal data, according to research from Lookout Security and separate findings from Symantec Corp. Fortunately, the malware isn’t very stealthy. To get infected , you would need to approve the download of the application, which masquerades as a security update. And the handful of known sites distributing it have low traffic, according to Lookout. “This threat does not currently appear to cause any direct harm to a target device, but could potentially be used to gain illicit access to private networks by turning an infected Android device into a proxy,” Lookout researchers wrote on the company’s blog. Mobile malware threats are not as widespread as those targeting PCs. Criminal hackers are experimenting with different business models for mobile devices, such as tricking users into subscribing to pay-text-message services that the criminals control. The lesson from the Not Compatible findings is similar to warnings PC users have gotten for years: The worst kind of update you can download to your machine is one that you didn’t ask for and don’t know where it comes from.

Twitter, an awe-inspiring story for SMEs

Twitter is growing fast at over 1.123 million accounts per day, which amounts to more than 13 new accounts per second. So, as an SME if you think you have an exciting product or service for the common man, just embrace Twitter

Small and medium businesses (SMBs/SMEs) are no longer social media-averse. Given the current growth rate, SMEs cannot discard social sites, especially if they want their products to go global and reach millions of people in no time. Among all the social sites currently available on Earth, Twitter enjoys a special spot. One of the best means to promote businesses, Twitter can spread the popularity of a product or service to every nook and corner of the world. Twitter, ranked one of the ten most visited websites, is growing fast at over 1.123 million accounts per day, which amounts to more than 13 new accounts per second. So, as an SME if you think you have an exciting product or service for the common man, just embrace Twitter. Look at IBM. Thanks to Twitter, the IT major can predict wait times at airports by crowdsourcing information from tweets. It tweets for mentions of airports, then send an @reply to the tweeters and ask them to reply with wait times. Another interesting fact is that scientists can tell with great accuracy where you are from just by the words you use in your tweets.

Currently valued at $8 billion, Twitter’s evolution is just mindblowing that a startup or an SME can do well to emulate. Like every startup, Twitter – when started in 2006 by Jack Dorsey – was just an idea with only three people working on it. The origin of the company goes back to a ‘day-long brainstorming session’ conducted by board members of the podcasting company, Odeo. Dorsey introduced this idea while sitting in a park and used the first Twitter prototype as an internal service for Odeo staff. This social networking site’s popularity shot up with the South by Southwest (SXSW) festival in 2007. Twitter usage increased from 20,000 tweets per day to 60,000 during the SXSW event and since then the company has not looked back. The number of tweets has ever been growing super fast. In 2008, there were only three million registered users and only 1.25 million tweets per day. Within the next one year, eight million users were registered with the site.
