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:

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 220.127.116.11.
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.

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.

In my last blog I discussed setting the stage in preparation for the Wi-Fi network for Mobile World Congress 2014 which supported more than 80k devices over a span of 4 days. Today I’ll talk about one of the many site surveys we conducted at the Fira Gran Via to ensure the success of our high density network. Full details in the white paper here.
High Density Wi-Fi deployments and site surveys go hand in hand. Pre-installation and post-installation site surveys account for the most effective way to identify the contours of your RF coverage and eliminate potential multipath distortions, hidden nodes, and other coverage issues. Special attention was given to the large keynote auditorium halls in order to keep a check on the additional RF coverage needs to accommodate the high density of users packed in a very close range.

The Hall-4 auditorium was one example of such a high density area with the 2000 person capacity area had a peak connection of 1924 concurrently connected Wi-Fi devices distributed across 16 Cisco APs while the Facebook keynote was in progress, with a max load of 530 Mbps of internet traffic. To avoid an RF overlap, the ceiling mounted APs above the auditoriums were converted to monitor mode. Using the final pre-keynote site survey data, the RF profile for the Hall-4 auditorium was tweaked, and RRM automatically optimized the coverage to the desired degree by adjusting the Tx power levels.

Every year a new attendance record is set at Mobile World Congress by networkers participating from over 200 countries across the globe. This grand attendance of industry-defining vendors, technology enthusiasts and exhibitors triggers an explosive growth in the number of Wi-Fi capable devices being brought to the event. For MWC 2014, Cisco partnered with Fira Gran Via and GSMA to pull off one of the most successful high density Wi-Fi network deployments in the history of global tech events. This blog kicks off a series to provide a glimpse of behind the network, into the design stages, and the course of actions undertaken to implement a robust high density wireless network which served more than 22,000 concurrently connected unique devices and a total of 80,880 devices throughout the event. Full details in whitepaper here.
Setting the Scene
Divided into eight massive exhibition halls, Fira Gran Via covers around 3 million square feet (280,000 square meters) of area which also includes outdoor areas, restaurants, conference rooms, network lounges and a continuous elevated walkway flowing through the entire venue. Higher the environmental complexity, the more fun and challenging it is to achieve the right wireless design for a pervasive network that meets all the needs.

Generally, the physical design of large convention and exhibition halls bear an impish knack of unfavorable conditions for a ubiquitous high density Wi-Fi network, owing mostly to the lofty ceiling heights and construction components. Read More »
