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of the first amendment to the IEEE 802.11 wireless networking standard hailing all the way since 1999, 802.11b was superseded by 802.11a and g in 2003 which are much more efficient. 802.11n was available in draft form in 2007 and was ratified in 2009 while 802.11ac was ratified last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

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 »

Founded in 2007, RetailMeNot.com is the largest digital coupon site in the US. They help hundreds of thousands of customers save money when shopping online. They are headquartered in Austin Texas, in the hip “Live Music Capital of the World”. Since the company went public in 2013, the company has doubled the number of employees from 250 to over 500.
In previous blogs, I have covered what is AVC, SuccessEHS and how Plixer’s Scrutinizer accepts Netflow, sFlow and IPFIX exports. This post will cover how these key products are combined by RetailMeNot in their WLAN deployments to optimize and support this fast growing company.
Recently Michael Patterson, the Founder and Product Manager at Plixer, Matthew St. Jean the Marketing Manager at Plixer and I had an opportunity to talk to Tim Tyndall, the Lead Network Engineer at RetailMeNot. Tim shared with us the highlights of the wireless LAN deployment and explained how they use Cisco Application Visibility and Control and Plixer’s Scrutinizer to stay in control of how their WLAN is being utilized.
Tim described the environment and culture that has become a huge part of the company’s success. RetailMeNot provides hip new offices for its employees with open work spaces and other awesome perks.
The Cisco powered wireless network supports this initiative. In fact, nearly all network connectivity is wireless. He said that employees are issued a laptop by the company and many carry in their own smartphones and tablets as well; Most of those devices being from Apple.
Employees can roam freely with reliable service that spans the company’s five floors. Even during large meetings where access density increases dramatically, service continues without any interruptions and the performance metrics they can obtain using NetFlow is exceptional and reinforce that the traffic is optimized.

Cisco has been playing a critical part for retail, healthcare, hospitality and transportation organizations to gain an understanding of how end-users move throughout an organization’s physical location. This is done through our Cisco Connected Mobile Experiences (CMX) solution.
With all the valuable information CMX provides, the demand for even more accurate data has been growing. Location accuracy has been a hot developing field and, as I mentioned in announcing our Best of Interop Finalist status in the wireless category last week, Cisco’s taken the lead in redefining how this location-based data is acquired.
In the past many solutions have relied on the probing performed by the mobile device to acquire location-based data. In recent months this approach has shown diminishing returns. The underlying issue is that this data is reliant on how frequently the mobile device probes an access point. A couple issues that arise include:
- Mobile device manufacturers are reducing the frequency of device probing to conserve battery. This reduces the number of data points collected and impacts the accuracy of the data
- Different manufacturers probe the access point with varying frequency so some devices deliver more accurate information than others skewing the location analytics data.
At Cisco’s annual Partner Summit event we are revealing some key areas of focus for the upcoming Cisco v8.0 release. Although the list is not inclusive of all new functionality, I would like to highlight some steps we are taking to bring CMX to meet the ever-evolving demand for location-based data.

As a Product Manager there is some anxiety but more of an excitement around introducing a platform to the market. Today I am proud to be part of Cisco team that is bringing to market the Cisco Aironet 2700 Series Access Point. What it offers is a tremendous amount of power at a very attractive price point.
We all know Wi-Fi is here to stay and is expanding all around us rapidly. That need for speed is exciting. But what does that mean? Not everyone feels comfortable being on the cutting edge. Many of our customers are not as concerned about chasing the future and have more limited budgets that they hesitate to put down for the best AP knowing there are lower priced options. At the same time, everyone is aware technology moves ahead with or without you, so they don’t want to give up lot of the new capabilities by going totally to the other extreme of not upgrading at all. What they want is something that’s going to last for a while that gives them the advantages available today, but not have to invest a lot to get it. I equate this to buying something like a car. A year ago when I was in the market to buy a new car I didn’t want to sacrifice whole lot of options but if there was one or two options that I could give up in order to save a bit of money, I was okay with that.
This is similar to what Cisco is offering with Aironet 2700 Series. Customers have to choose something that they can utilize in their network that is better than any of the competitive solutions out there, truly built-for-purpose, sleek design on the outside yet tough on the inside and very powerful.
