3 Steps for Best-in-Class Wi-Fi

If you are a professional photographer or even an amateur like me, you want to have ready access to various control dials on your camera to capture the moment perfectly. Professional cameras provide high level of control to get the best outcome. But there are times when you want to put the camera and the lens in Auto mode or wish that the camera could automate some decisions that make your workflow easier.

Likewise, Cisco Wireless LAN products provides the level of quality, functionality and control that is unmatched and hands-down the best enterprise wireless networking portfolio in the industry. But there are scenarios where it is preferable to expedite wireless configuration with best practices automatically enabled and easy access to data to simplify monitoring and troubleshooting workflow. For example, a small business owner manages his own network or in a K-12 a librarian acting like a part-time IT administrator. This not only provides operational efficiencies for the IT organization but also improves end-user and partner experience.

Cisco WLAN Express Setup is an attempt in this direction. It is now available on 2500 Series Controller (CT2504) starting with software release 7.6.120.0.

It includes three components

  • Easy-to-use setup wizard: This eliminates the need for console cable and command line setup. Instead, 3-step web-wizard is used to quickly boot strap a Controller and configure employee and Guest WLAN out of the box.

The Summer Blockbuster You’ve Been Waiting For: Cisco Wireless Release 8.0

Cisco Wireless Release 8.0 is now available: Product Bulletin 

The Cisco VNI Global Mobile Data Traffic Forecast, 2013 – 2018 revealed some stunning trends with growth projections that are sure to have a dramatic impact on wireless networks worldwide.

In 2013, globally, there were nearly 22 million wearable devices generating 1.7 petabytes of monthly traffic. There were about 7 billion mobile-ready devices and connections with mobile network connection speeds that have more than doubled, to 1.4Mbps up from 526 Kbps in 2012.

By 2018, there will be more than 10 billion mobile-ready devices and connections. The average mobile connection speed will nearly double, from 1.4 Mbps in 2013 to 2.5 Mbps and over 4.9 billion devices will be IPv6-capable. There will be more traffic offloaded from cellular networks (on to Wi-Fi) than remain on cellular networks.

Wi-Fi & Taxes: Digging into the 802.11b Penalty

It’s that time of year again in the US – Tax Time!  That time of year where we review the previous year’s bounty, calculate what’s due, and re-evaluate our strategies to see if we can keep more of what we worked for.  Things change; rules, the economy, time to retirement, and before you know it you find yourself working through alternatives and making some new decisions.

Anyway, as I was working through the schedules and rule sheets, my mind wandered and I started to think about Wi-Fi and the taxes associated with it.  In my day job, I often play the role of forensic accountant.  Like a tax accountant, I’m always looking for a way to get more or understand why there isn’t more already.  So along those lines, lets talk about a little known tax that you may well be paying needlessly.  I’m talking of course about the dreaded 802.11b Penalty.

Wi-Fi protocols like 802.11b are referenced by standards committees for the workgroup that develops them.  In the 2.4 GHz spectrum, there is 802.11b, 802.11g, and 802.11n.  Back in 1997, 802.11b  was the first modern Wi-Fi protocol ratified by the IEEE and it allowed transmissions of 11 Mbps, a major jump forward from the previous 2 Mbps  that was possible with the original 802.11 standard.

After 802.11b came 802.11a, and then 802.11g.  Both of these protocols where a radical departure from the simplistic 802.11b structure and employed Orthogonal frequency-division multiplexing (OFDM) modulation (now standard in every 802.11 protocol created since then).  OFDM allowed for Read More »

Top 10 Reasons to Upgrade to the 7.4 MD Software Release

As the famous saying goes, “Good things come to those who wait”. Delayed gratification -- person’s ability to forgo a smaller reward now for a larger reward in the future -- has been linked to better life outcomes as demonstrated by the often cited Stanford Marshmallow experiment and others. In most cases though, it requires a degree of self-control not easily achievable in today’s fast paced, ever-changing world with new mobile devices, protocols and technologies.

If you are one of the Cisco Wireless customers currently deploying Release 7.0 MD and waiting for the next Cisco Wireless Software Maintenance Deployment Release, the wait is over!

Release 7.4.121.0 has achieved Maintenance Deployment (MD) status.

Release 7.4.121.0 is the recommended MD release for all non-802.11ac deployments. For 802.11ac deployments, Release 7.6.110.0 (Release 7.6 Maintenance release 1) is the recommended release.

For additional details on Software Release Recommendations and Guidelines, see Guidelines for Cisco Wireless Software Release Migration

Below are top 10 reasons (in no particular order) to upgrade from the current 7.0 MD release to the latest 7.4MD Release.

10. FlexConnect (improved and rebranded H-REAP) with efficient AP upgrade across WAN, BYOD policies support, Flex ACLs and split tunneling. Read More »

Is Your WLAN Ready for Unified Communications & Collaboration?

January 31, 2014 at 5:00 am PST

As Wi-Fi continues to be the primary mode of access, enterprise Unified Communication(UC) applications usage is increasing with smartphones, tablets and laptops.

Customers are asking, is there anything I can do to prioritize Jabber or Lync traffic over others or even identify how much of the traffic is really collaboration traffic vs. other types of media. The recently introduced Wireless Release 7.6 enhances the ability to classify Microsoft Lync 2013 and Jabber with Cisco WLAN Infrastructure.

In the first blog about Application Visibility and Control over Cisco WLAN, I captured what is AVC and the capabilities included in the release 7.4. In a subsequent blog, I had captured a success story about a customer who benefited from the reliability by deprioritizing scavenger level applications as well as captured highlights of the enhancements in release 7.5. This blog captures how the release 7.6 allows popular collaboration applications to be accurately classified and prioritized as well as provides a teaser to some of the innovations that can be expected in the future.

What exact capabilities AireOS 7.6 provide ?

The protocol pack 6.3 introduced in AireOS 7.6 allows you to identify and prioritize not just Jabber but also sub-classify Cisco Jabber Audio, Cisco Jabber IM and Cisco Jabber Video. Customers may want to prioritize the Cisco Jabber Audio as the highest priority while the others may be lower priority. Similarly you can classify not just Microsoft Lync but also Microsoft Lync Audio, rtcp and Microsoft Lync Video and thereby prioritize them separately. Read More »
