White Paper: RX-SOP 101

Just released yesterday: Cisco Wireless Release 8.0 includes a feature called Receiver Start of Packet (RX-SOP), which you can think of as putting earmuffs on the access point.  It’s not a new feature, as it has been used in stadiums and other high density deployments to great success for several years.  WLC 8.0 adds GUI configuration support with a low, medium, and high setting.

RX-SOP is meant for dense deployments, where channel reuse is a concern.  It’s a way to shrink cell sizes, but be careful: too much SOP and you can shrink your cells to the point where clients are no long able to connect.

Check out this whitepaper from the guys at the No Strings Attached Show.  It provides detailed configuration guidance as well real-world data--even the actual config.

For those of you interested in the nitty-gritty of how RX-SOP works, we had one of our RF Technical Leaders, John Blosco, go in-depth at Wireless Field Day 7.  If you missed it, here’s the video:

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.

Bring Out Yer Dead: 5 Steps to Eliminate 802.11b From Your Networks

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:

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 »
