Now that US tax day is over, we in the wireless field can get back to focusing on P1: optimizing and maintaining network performance. Keeping your network in good shape is like gardening: if you don’t pull out the weeds, it’ll never look as good as it could. My friend Jim Florwick detailed the gory bits of the 802.11b penalty with its awful lag in efficiency and absolute waste of spectrum. I write today to help give you the steps to act on Jim’s order to stop the madness.
I liken this process to a memorable scene from Monty Python: You must “Bring out yer dead.” However much the first standard insists it’s still alive, let’s all be honest with ourselves: 802.11b is dead.
In memoriam of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient. 802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last September. A few years from now we should be planning the wake for 802.11a and 802.11g as well.
Now is the right time to bury 802.11b and reduce the drag on your network. Let’s be real: there is a reason cyclists are not allowed on the freeway, and an 802.11b device will slow everyone down. Here are 5 easy steps for eradicating your network of 802.11b and getting on your way towards higher speed wireless:
STEP 1. Identify any 802.11b devices on your network
All of the latest Wi-Fi connecting devices are 802.11a/b/g/n capable. So how do you hunt down the 802.11b-only devices? You’ll be looking for older laptop and mobile clients (mostly before the year 2005).
Cisco Prime Infrastructure makes this easy for you with a report on clients by protocol. It will look like this:

As advancements in mobility continue to accelerate across all industries, one area that appears poised for some of the deepest transformation is healthcare.
Already, we are seeing how mobility adoption in hospitals — along with new personal health-monitoring devices — is enabling better patient care and a healthier society. And all of these breakthroughs dovetail into the revolution that we call the Internet of Everything (IoE) — the explosion in connectivity among people, process, data, and things that is transforming our world.
A great example is Brazil’s Universidade Federal de Sergipe, which is utilizing telehealth technology to provide patients with specialty healthcare. In the United States, nearly 70 percent of surveyed healthcare leaders say that clinicians at their organizations use mobile technology to view patient data, according to a new survey from HIMSS Analytics.
It’s also estimated that more than 17 million wearable bands will ship this year, putting new health-monitoring tools directly in the hands — or on the wrists — of patients. And with the deployment of strong wireless networks, such as the one used by Miami Children’s Hospital, hospitals are supporting a holistic mobile-enabled patient-care experience that is providing strides in electronic health records. Another intriguing breakthough involves devices such as the Scanadu Scout, which makes the handheld medical “tricorder” of Star Trek fame a consumer reality. Such advances are helping doctors, nurses, and patients reduce errors in miscommunication, while cutting costs.
It isn’t about just becoming more mobilized; it’s about improving patient care and individual well-being. As Addison McGuffin, vice president of business technology innovation at Health Care Service Corporation, said, “Some of the things we’re looking at is a trend toward technology that is helping patients toward health performance and improvement on a daily basis.”
These examples show how mobility is reshaping the healthcare industry. Yet, according to a recent Forbes article, many hospital administrators perceive a “double-edged sword” when balancing the need to invest in technology with regulatory constraints. This topic also drove conversation at the recent HIMSS conference. At Kaiser Permanente’s booth, they asked the question: “Is Health IT Really Worth It?” With advancements in mobility shaping IT strategy and investments, I’d take Kaiser’s question a step further by asking, “Is Mobility in Healthcare Really Worth It?” Read More »

In my role as Cisco’s Chief Futurist, I get many questions about what the future holds and how new technology and emerging solutions will change our lives. Be sure to check out previous Ask the #InternetOfEverything Futurist blogs and videos about the advances of battery technology, the future of smartphones and new retail models.
Greek philosopher Aristotle first classified the five senses of human perception: sight, smell, taste, touch, and hearing in De Anima, a landmark piece of work that explores how we interpret reality.
Today, Aristotle’s belief about senses still holds true: Our senses help us obtain a better understanding of the world around us. And as the Internet of Everything (IoE) connects more people, process, data and things, emerging technology and the network to support such technology is playing an increased role in our sensory development and capabilities.
New solutions that rely on haptic touch technology, sensors and real-time data transmission protocols are no longer requiring us to touch or even see technology in order for us to interact with it. These innovations coupled with the power of the Internet of Everything are creating enhanced experiences for us – and a new way of viewing, hearing, smelling, tasting and touching our world.
In today’s Ask the #InternetOfEverything Futurist post, I’ll answer a question from Cisco Champion Karen Woodard’s student, Kurt, who addresses this type of IoE-enabled sensory technology evolution. Kurt asks:
Question: “How will the future of technology integrate into our five senses?”

It’s that time of year again in the US – Tax Time! That time of year where we review the previous year’s bounty, calculate what’s due, and re-evaluate our strategies to see if we can keep more of what we worked for. Things change; rules, the economy, time to retirement, and before you know it you find yourself working through alternatives and making some new decisions.
Anyway, as I was working through the schedules and rule sheets, my mind wandered and I started to think about Wi-Fi and the taxes associated with it. In my day job, I often play the role of forensic accountant. Like a tax accountant, I’m always looking for a way to get more or understand why there isn’t more already. So along those lines, lets talk about a little known tax that you may well be paying needlessly. I’m talking of course about the dreaded 802.11b Penalty.
Wi-Fi protocols like 802.11b are referenced by standards committees for the workgroup that develops them. In the 2.4 GHz spectrum, there is 802.11b, 802.11g, and 802.11n. Back in 1997, 802.11b was the first modern Wi-Fi protocol ratified by the IEEE and it allowed transmissions of 11 Mbps, a major jump forward from the previous 2 Mbps that was possible with the original 802.11 standard.
After 802.11b came 802.11a, and then 802.11g. Both of these protocols where a radical departure from the simplistic 802.11b structure and employed Orthogonal frequency-division multiplexing (OFDM) modulation (now standard in every 802.11 protocol created since then). OFDM allowed for Read More »

Digital Marketing Executives, trade press and specialist companies gathered in New York this week for the latest ClickZ Live NYCevent.
Location, location, location…!!!
A very clear trend visible here is how location had become a key part of the digital marketing language.
It was part of the Keynote addresses.
- Facebook’s former Director of Marketing is advocating it.
- Google are presenting on it and delivering workshops on it.
- Various booths talk about its importance.
- Numerous speakers mention it in their presentation.
- And Cisco are evangelizing how indoor location using WiFi and CMX can really enhance location capabilities and hugely driven additional revenue streams and enable new business models. Read More »
