Wireless UI Walkthroughs

Recently I created two wireless vendor UI walkthroughs and thought they would be worth sharing with the NCI crowd.

The first walkthrough is of the Meraki Systems Manager. This feature is built-in to the Meraki Enterprise Cloud Controller and offers a fairly extensive set of MDM features to Meraki customers at no extra cost.

 

The second walkthrough is of the Aruba Instant Virtual Controller UI. The Instant architecture does away with hardware controllers, feature licensing, and even simplifies the administrative experience.

 

I hope you find the videos interesting. As always, if you have any questions, or would like a live demonstration please do not hesitate to contact us.

Bonus Marks: Did you spot the hidden surprise in one of the videos?

Streaming Video vs The Corporate WLAN

Sometimes words are just not enough, but seeing is believing.

The picture, above, shows the results of a little lab test I did to see just how much of the available wireless spectrum streaming video would consume. For this test, I recorded three seperate video sources:

  1. YouTube 1080p.
  2. Netflix using the Good Quality setting – upto 0.3 GB/hour.
  3. Netflix using the Best Quality setting – upto 1 GB/hour.

A proper explanation of everything shown in the picture is a bit beyond the purpose of this blog post, but I will try to highlight the important bits:

  • There is a noticable increase in wireless activity during each video. In fact, the duty cycle during the YouTube video was up to 73 percent! Put another way, anyone else trying to access the network via that access point would have been very annoyed.
  • Even at the Best Quality setting, Netflix was not as ‘spectrum-unfriendly’ as YouTube.

As we allow more and more bring your own device (BYOD) access in the enterprise, we need to make sure we have a plan or policy for dealing with this type of traffic. The spectrum available to WLANs is not limitless. Left unchecked, a few streaming videos at the office could have a major impact on the proper functioning of wireless applications and VOIP capabilities. What’s your strategy for dealing with the type of traffic? Do you block it entirely? Do you block it on the WLAN and allow it on the LAN? Rate limit? Whatever you decide, you want to make sure it is you making the decision and not the BYOD devices.

Bonus Question: Based on the picture, can you determine which 802.11 standard was being used and what my theoretical maximum bandwidth was at the time?

Welcome to the New Website

It is with great pleasure that we welcome you to the new and improved NCI website. Our development team has committed enormous amounts of energy and passion to the project and the result is a completely revamped NCI experience.

Our goal is to turn this website into a regular source of information and conversation for anybody interested in security and/or information technology. Some of the changes you can start taking advantage of immediately are.

  1. Site Search – Our new CMS has an extremely powerful site-wide search engine. It’s never been easier to find what you’re looking for.
  2. Videos – We are very excited to be able to produce industry-related videos for all to see. The content will range from product demonstrations to tutorials. Best of all, you’ll be able to view them embedded on our website or via our YouTube page and/or via our Vimeo page.
  3. Social Media – The @ncisocial Twitter account has already been active for some time now. Be sure to follow us and be the first to know when new content is posted. We will continue to evaluate additional social networks and bring new accounts online within the next few months.
  4. SlideShare – We are always creating presentations and technical briefs for our customers. You will now be able to view these documents online by visiting our SlideSpace. It’s like having access to NCI’s internal library of technical materials from anywhere in the world!

We look forward to opening two-way communications with you. Please feel free to post comments, contact us via Twitter or directly via email and let’s start a conversation. This website is really a gift to you and we are happy to welcome you to the new nci.ca.
