What Next for BYOD?

One of the interesting and challenging aspects of working in the Mobility space is the sheer pace at which the industry is moving.  I’m fortunate to work with many Customers in EMEA to help support and shape their strategy towards Mobile technology.  A great example of this has been the reaction to BYOD.

The influx of personal devices into the Enterprise caused by the BYOD trend poses numerous challenges to IT Departments.  Understandably, initial reaction was to focus on network and device level Security.

Cisco responded by introducing a BYOD Solution to remove some of the burden from IT Departments and provide them with a central point for managing many aspects of the BYOD lifecycle: onboarding, device profiling, authentication, authorization, offboarding and self-service management.

Almost at the same time, a new industry segment was created: Mobile Device Management. The intent of MDM systems is Read More »

HDX Blog Series #2: Scaling with Turbo Performance

Editor’s Note: This is the second of a four-part deep dive series into High Density Experience (HDX), Cisco’s latest solution suite designed for high density environments and next-generation wireless technologies. For more on Cisco HDX, visit www.cisco.com/go/80211ac.  Read part 1 here

With any new technology comes a new set of obstacles to overcome.  802.11ac is no exception.  Last week we talked about CleanAir for 802.11ac and why spectrum intelligence still matters. Another challenge is scalability. In this post I will give you some details on new HDX feature, Turbo Performance, which allows the AP 3700 overcome common scaling issues to scale amazingly well.

What’s Different with 802.11ac?

802.11ac means higher data rates, which means more packets per second (PPS).  There are three reasons for more PPS with 11ac: wider channels, increased modulation and increased aggregation.  Channel width doubled to 80 MHz, modulation increased from 64 QAM to 256 QAM, and aggregation increased from 64k to 1MB!

With 802.11n, an AP might have had to push 30,000 1500 byte packets per second through the APs data plane. Today with 802.11ac that could now be 75,000+ PPS.  More PPS means more load on the APs CPU, so to really keep up with the demands of 802.11ac, we needed to go back to the drawing board.   Read More »

The IoE Enterprise: Diverse, Inclusive, and Hyperconnected

If it seems as if the roles of chief information officer (CIO) and chief diversity officer (CDO) rarely overlap, think again. In today’s hypercompetitive — and hyperconnected — global marketplace, inclusion, collaboration, and technology are merging as essential drivers of innovation and business success. And the relationship between the CIO and CDO may never be the same.

Indeed, fostering a policy of inclusion and diversity in your organization isn’t just the right thing to do; increasingly, it is also the profitable thing to do. And, it’s a clear business imperative, since great ideas come from all corners — and levels — of the organization.

In a Cisco survey of 7,500 companies, 93 percent of enterprises with a formal policy of inclusion reported that their collaboration technology investments outperformed their business value expectations. That’s just one example of the inclusion/diversity/value equation at work.

Deploying, Testing, and Tuning 802.11ac

By now you’ve probably heard quite a bit about the newest generation of Wi-Fi, 802.11ac.  I’ll save you the gory details, just know it’s about 3x faster than 802.11n and will help to improve the capacity of your network. Jameson Blandford and I were recently guests on the No Strings Attached Show podcast with Blake Krone and Samuel Clements (Click to listen to the podcast).

I wanted to follow up the podcast with a blog to go over considerations for deploying, testing, and tuning 802.11ac.

Considerations for deploying 802.11ac

Switching infrastructure

The first question you’ll want to ask yourself, is, if your switching infrastructure can handle 11ac?  The answer probably is, yes.  The things to consider are the port speed and power-over-Ethernet (PoE) capabilities.  You’ll want the access point to have a gigabit uplink to the switch.  Each 11ac access point could potentially dump several hundred megabits per second of traffic onto your wired network.  It’s also not a bad idea to have 10 Gig uplinks on your access switches to distribution or your core.  If you have even just a couple access points on a single access switch, you may quickly find yourself wishing you had 10 Gig uplinks.

Next you’ll need to consider how you will power the access points.  If you are like the majority of our customers, you will use PoE from your switches.  While 11ac access points require 802.3at (PoE+) for full functionality, the Aironet 3700 will run happily on standard 802.3af PoE.  In fact, it remains 3 spatial-streams on both radios, so performance does not suffer because you have a PoE infrastructure.
