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:

Behind the Network @ Mobile World Congress 2014: Hotspot 2.0

Mobile World Congress (MWC) 2014 was the largest mobile industry exhibition in the world, where over 1800 companies showcased and launched their latest products and services. This event was visited by over 85,000 attendees from over 200 countries around the world, to learn, network, inspire and innovate. Providing them seamless and robust data network was the first priority. GSMA , Fira de Gran Via and Cisco took this challenge to provide them next generation Wi-Fi experience with seamless connectivity and onboarding using Hotspot 2.0 service on the top of baseline free Wi-Fi service.

Hassle and risk are the two key factors involved in connecting free public Wi-Fi. When you are traveling in the different countries, you get off the plane and turn on your cell phone… and within few seconds you get connected to the cellular network. There is no need to search for a suitable network manually (hoping it’s not rigged by a hacker), then enter long password or credit card details to pay for the service. But unfortunately connecting to Wi-Fi is not that simple. Hotspot 2.0 Service addresses these problems by automatic network discovery and selection, seamless network access and secured authentication for the Passpoint certified devices.
