Bring Out Yer Dead: 5 Steps to Eliminate 802.11b From Your Networks

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of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient.  802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last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:

Connected Healthcare: How Mobility Drives Better Care and a Healthier Society

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 »

Boingo Takes Next Generation Hotspot from Roadmap to Real Life

This is a customer perspective guest blog contributed by Zack Sterngold, Boingo Wireless Vice President, Americas.

The vision for a simple, seamless and secure Wi-Fi connectivity experience became a reality timed to this year’s Mobile World Congress. And by design, this major milestone was simple, unobtrusive and even invisible to those who weren’t looking for it.

Years in development, Next Generation Hotspot protocol trials have been put to the test at industry conferences around the world, from Beijing to Paris, to the first commercial Next Generation Hotspot test bed at Chicago O’Hare Airport, launched by Boingo in late 2013. At MWC 2014, Cisco, AT&T and Accuris partnered to bring a Hotspot 2.0 network to the Fira Gran Via, reaching the largest audience of industry influencers ever.

Halfway around the world, the Boingo team made a bold move. The time for limiting easy, secure Next Generation Hotspot connectivity to the industry elite had passed. The time had come to invite the multitude of consumers looking for fast, seamless connectivity to experience the future of wireless. Read More »

Non-Stop Wireless Network at John Muir Health

April 15, 2014 at 8:12 am PST

Previously I have blogged about No SSID Outage and No Client Reauthentication whereby even if your Cisco Wireless Controllers were to fail due to any reason, the clients will NOT experience any downtime due to Stateful Failover functionality to a Standby Controller. What could be better than that? Controllers that never go down!

A picture is worth a thousand words! As you can see the above the WEBGUI on a 5508 series wireless controller shows that, it is running 7.0 code which was an MD release, has been operational for over a thousand days or over three years! Read More »

How A School District Prepares for PARCC and More

CreepyKidIndian Prairie School district, the third largest school district in Illinois, conducted an in-depth investigation to develop an execution plan to adopt Partnership for Assessment and Readiness for College and Careers (PARCC) consortium guidelines and meet the Common Core State Standards head-on. Their execution plan took them beyond the basic requirements of online testing to providing a secure, borderless learning environment for a variety of devices, over wired and wireless.

Not only was this a great opportunity for them to upgrade their network to meet the state and national testing standards, but also to lay the foundation for any future requirements as technological advances are rapidly changing the education landscape.

Requirements: 

  1. Meet the computer-based testing requirements under PARCC
  2. Provide a borderless learning environment through mobile and online learning
  3. A stable infrastructure that can meet the dynamic network demand
  4. Prepare for the growing importance of technology in classrooms, wired and wireless, with trends such as BYOT (Bring Your Own Technology) as well as an increased use of district-owned devices.
