Gartner has released their 2014 Magic Quadrant for Wired and Wireless LAN Infrastructure. For the 3rd year in a row, Cisco is recognized as a leader in both vision and execution. We believe this Gartner recognition is validation of Cisco strategy and investments for unified access, policy management and cloud managed solutions.
Cisco’s position in the Wired and Wireless Gartner MQs has been consistent over the past 3 years as the market landscape has shifted we believe validating our commitment to meeting shifting customer priorities and requirements.
“With limited growth in IT resources, administrators require one network management application, one access security solution, one guest access application or one policy enforcement solution with the flexibility to be deployed in a public cloud, private cloud or on-premises. This integration reduces the costs associated with the upfront capital expense of multiple network service applications each dedicated to either the wired infrastructure or the wireless or cloud components. This savings is also extended to the ongoing software maintenance costs of all access layer management, security and policy enforcement components.”
In my last blog on 5 GHz spectrum, I discussed the recent FCC ruling that permitted outdoor access points to use the U-NII 1 band (5150-5250 MHz).
But the story doesn’t stop there. As mentioned last time, there are significant technical challenges to using the 5 GHz band. It is not cleared spectrum. It contains incumbent uses that are important for national security and public safety. Therefore, it is imperative that Wi-Fi not create harmful interference to these incumbent systems. Cisco will not settle for less.
On the topic of interference, a particularly interesting component of the same FCC ruling that opened the U-NII1 band for outdoor AP’s is that it also re-opened the Terminal Doppler Weather Radar (TDWR) band (channels 120, 124, 128) with new test requirements for DFS protection. Hold on, let’s backtrack a bit before diving into what this means:
What is TDWR?
In brief, Terminal Doppler Weather Radar (TDWR) “is a Doppler weather radar system used primarily for the detection of hazardous wind shear conditions, precipitation, and winds aloft on and near major airports situated in climates with great exposure to thunderstorms in the United States.” TDWR uses the frequency band from 5600-5650 MHz which is why wireless network equipment needs to be proven to “do no harm” to TDWR.

A Brief History
Many of you reading this will recall that the FCC closed the use of the TDWR band several years ago as the result of numerous reports of wireless equipment creating interference with TDWR. Read More »
In just two years, indoor location technology has taken off and attracted a lot of buzz across industries, from retailers to healthcare. But it’s no longer a conversation about just Wi-Fi – the introduction of beacon devices, including iBeacon, has added a new dimension to location technology for IT and their line of business counterparts to grapple with on how to leverage it to better reach their customer base.
Some customers have been asking about beacon technology and how it fits in with Wi-Fi, so let’s start from the beginning:
How do beacons work?
Beacons are sensors that send out Bluetooth low energy (BLE) tracking tags. These sensors can be placed around a venue, such as a store, and a mobile device can pick up the BLE signal and determine that it is in close proximity. When a mobile app is built off of this technology, it can be used in interesting ways to interact with the end user, such as notifying a customer of a promotion for an item they are close to.
I’m having trouble differentiating Wi-Fi and beacons. What do I need to know? Read More »
There is no denying it: your employees and customers are streaming video. While the volume of that streaming dramatically peaks around game times during the World Cup, it should be no surprise that today, mobile applications, largely video, are increasing mobile traffic across networks. That’s straight forward: apps + video = bandwidth drain. Combine that with the fact that people are touting multiple devices–think a laptop and a smartphone, maybe a tablet, too. This means high density–lots of clients and devices on a single network. These circumstances trigger three potential yellow cards to cross an IT person’s mind – let’s see how we can avoid them.
YELLOW CARD #1: Rich Media Optimization
As an end-user, the common expectation is that I should get the same crisp, clear, rich media or video experience across all platforms—I don’t care if it’s my phone, my tablet or my laptop: make it high definition. This is harder said than done.
It is not easy to provide the same rich media experience across wired and wireless devices. Traffic from wireless devices has to travel all the way back to the controller in a data center and then back to an access switch before reaching its destination. It’s called the hairpin effect. The result is that video over Wi-Fi could look grainy. That won’t do for the current generation of high definition junkies. Read More »
One of the best times I always have at Cisco Live involves getting to play ‘TV Anchor’ for the various live shows we stream. Well the Cisco TV team lets us use their equipment to do a live version of TechWiseTV each afternoon as well. Now honestly, I do plan these out…a little. But our day three show is generally a ‘hey…what do we WANT to do” kind of show. Planning for day 3 simply involved asking Jimmy Ray and Tina what they wanted. We had TWO wireless cameras this year to play with so it felt like we could do a little more. As for me (with input from the hillbilly of course), we wanted to take advantage of Wireless Stew’s presence and get him up to tell his story…so that is how we started.
Stewart Gouman’s is a fantastic fan of the show, running his wireless consultancy and very informative blog from the Great White North. He has sought us out in just a few visits over the years stopping by the studio in San Jose or catching us while at Cisco Live when we all end up in the same place. Watch the show and get his career and community advice.
