Super-Fi OK’d by IEEE

Super-Fi OK'd by IEEEI usually don’t have a problem getting a wireless signal where in my Bach Seat. However, there are some areas where I coordinate technical services that don’t get wired or wireless Internet. In these rural areas, where AT&T (T), Verizon (VZ), Sprint Nextel (S), and Comcast (CMCSA) and their fellow travelers fear to tread because they can’t make a buck in these areas, some help may be on the way from the IEEE.

IEEE logoIn 2009, the Institute of Electrical and Electronics Engineers (IEEE) started the development of IEEE standard 802.22, which addressed the need for broadband wireless access in rural areas, those where it is not economical to deploy a wired infrastructure. In July 2011, the IEEE announced that it has published the standard titled: “IEEE 802.22-2011 Standard for Wireless Regional Area Networks in TV Whitespaces” (PDF).

The IEEE press release states: “This new standard for Wireless Regional Area Networks (WRANs) takes advantage of the favorable transmission characteristics of the VHF and UHF TV bands to provide broadband wireless access over a large area up to 100 km (60 miles) from the transmitter. Each WRAN will deliver up to 22 Mbps per channel without interfering with reception of existing TV broadcast stations, using the so-called white spaces between the occupied TV channels.”That part of the spectrum, known as white spaces, sits between broadcast TV channels and will become available when broadcast TV stations switch from analog to digital in 2009.

VHF and UHF TV bands to provide broadband wireless accessThe White Space Coalition led by Microsoft (MSFT), Google (GOOG), Dell (DELL), and other tech titans strongly support the use of the white spaces in the U.S., going up against strong opposition lead by Michigan’s own John Dingell and big media like the NFL, MLB, NASCAR, NBA, NHL, NCAA, PGA Tour and ESPN who say unlicensed devices in the TV bands would interfere with their signals.IEEE 802.22 reportedly will not interfere with TV broadcasts, because it incorporates advanced cognitive radio capabilities including:

I met Mr. Dingell about a dozen years ago, at a school to encourage the politician to support schools when the USF started the eRate program for schools. I recall Mr. Dingell telling me he could not support eRate because he did not trust the FCC to get it right. At least he is consistent.

I believe there is a very good chance this technology will never be a commercial success. The wireless carriers will squash this technology like they have squashed municipal wi-fi and community fiber networks. The improved speeds and coverage areas are a threat to their limited 4G coverage and they would lose out on their monthly pound of flesh capped rate-limited data plan.

It will be up to us in the public sector to implement this technology for our clients.

What do you think?

Will Super-Fi ever see the light of day?

Wireless Charging for iPhone

Wireless Charging for iPhoneApple Computers (AAPL) has fired an opening shot in the wireless charging patent warfare. Patently Apple reports that the now Jobs-less firm has filed for patent protection on inductive wireless charging for iPhone, iPod, and iPad. The patent “Using an Audio Cable as an Inductive Charging Coil,” is available at the U.S. Patent Office website.

TApple logohe patent application in typical Apple style, calls for a “wireless” charging solution that uses wires. Apple wants to use headphone wires rather than supplying a power cable. The wired wireless charging system includes a tower that would sit atop your desk. According to MIT’s Technology Review, to charge an iPhone, specially designed earphones must be wrapped around the tower multiple times. Finally, the earbuds are to be placed on the device, where special conductive metal mesh would begin funneling electricity to your device.

Apple Inductive Charging Patent

TR says the charging tower is an eyesore, wrapping earphones around it would be a hassle and the whole thing is decidedly un-Apple-like in its unwieldy and cumbersome nature. Other opinions are “Incredibly impractical,” “ridiculous,” “like an iPhone scratching post,” “Tolkien-esque.”

WiTricity logoTR and Gizmodo believe this patent application is a “red herring” and Apple has other things in mind. Back in May 2011, MacRumors noted Apple’s interest in WiTricity, As MacRumors pointed out an international patent application filed by Apple which cites the original MIT paper as the foundation of WiTricity’s business plan.

I have already covered wireless electricity a couple of times. The obelisk charging patent is so out of character for Apple design that I believe it is a head-fake. With their closed eco-system, Apple can create a closed version of the WiTricity technology and charge a premium for it.

Your Desk is Killing You

Your Desk is Killing YouThere is a growing body of that evidence that your desk is killing you. Research suggests that sedentary office workers and other inactive people are at a relatively high risk of dying early. MIT‘s Technology Review reports that sedentary people have higher levels of biomarkers linked to cardiovascular disease, including insulin, glucose, and triglycerides.

Research in animals has shown that levels of an enzyme that is responsible for breaking down fat plunge when they are forced to be inactive. The article says that intensive exercise doesn’t affect the fat-metabolizing enzyme. So even daily workouts won’t necessarily protect people who spend eight hours a day sitting at a desk.

Few firms have tried to figure out ways to make office work less sedentary. “For most people with indoor office jobs or doing lot of driving, work is really the biggest chunk of sedentary time during the day,” Neville Owen, professor of health behavior at the University of Queensland, Australia told Technology Review. The average American spends about 10 hours a day sitting, and the problem is getting worse.

Choose between sitting at your desk and standing during the day

The Professor’s team is beginning a clinical study in which office workers are given adjustable desks. They let the workers choose between sitting and standing throughout the day. These desks are growing in popularity. However, they cost about $1,000 each, employers want to know if they really work.

TR reports that participants in the study will wear meters. The meters will measure their activity levels to find out if the expensive desks reduce sitting time. The researchers will also measure the participants’ markers of cardiovascular disease. They will see if the levels of glucose, insulin, and triglycerides are impacted by the changes in their habits. “We will also look at participants’ perception of their own energy levels,” says Professor Owens.

Change workplace culture

Another approach to the problem being studied is to make it more acceptable to walk around while at work. According to the article, Ken Smith, a researcher at the Stanford Center on Longevity is working on a pilot project at a call center in California. “We want to explore cultural changes in the workplace that make it OK to stand in a highly sedentary environment like a call center, where it might be frowned on to walk around, or not even possible,” he says. “Part of the study will be to look at the impact on productivity.”

Walking at workTargeting inactivity on the job may prove easier to carry out than getting people to exercise according to the article. “A lot of the workplace wellness is around discretionary exercising,” says Professor Owen. “… Workplace sitting is more integral, more structural. It largely has to do with workplace design and giving options for adjusting sitting and standing.”

Meanwhile, the most common advice from physiologists is to get up as much as possible: go get a drink, do a quick stretch, or walk over to see a colleague rather than sending an e-mail.

I wrote about this issue here. Other research has shown that physical activity and exercise can benefit employers because it

• Improves attention, focus, memory, and reading retention
• Improves brain function making it ready to learn and absorb new information
• Increases executive function at work
• Reduces stress and anxiety

Adobe Flash Still Full of Holes

Adobe Flash Still Full of Holes

I wrote about Adobe’s (ADBE) problem with writing secure software earlier. The problems still exists according to an article in Help Net Security. The article lays out claims by Google (GOOG) researcher Tavis Ormandy that he notified Adobe of some 400 holes in  Flash Player. According the the article, Adobe fell short on the latest Flash patch. In the article Mr. Ormandy claims that Adobe’s latest release of Flash:

  • Only patched 13 fixed holes in the application, failed to document other holes; and
  • Did not give credit to those that found the bugs using a technique called fuzzing to reveal the bugs.

the Google researchers wrote on their blog, “The initial run of the ongoing effort resulted in about 400 unique crash signatures, which were logged as 106 individual security bugs … each crash was treated as though it were potentially exploitable and addressed by Adobe. In the final analysis, the Flash Player update Adobe shipped earlier this week contained about 80 code changes to fix these bugs.”

Adobe Flash Still Full of Holes

Help Net Security notes that after an initial silence on the matter, Adobe told Computerworld, that Mr. Ormandy had reported some 80 bugs in Flash Player, but defended their decision to not list all the vulnerabilities in the released security bulletins by saying that it usually doesn’t reveal or mention vulnerabilities found internally – by them or their partners. Also, the question is whether all those 80 flaws would lead to an exploitable hole. It seems that Adobe believes that only holes get a CVE number.
