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:

Passaic County Technical Institute (PCTI) is a leading career and technical high school located in Wayne, New Jersey. Listed among the best high schools three years in a row according to US News & World Reports, PCTI is the largest school of its kind in the state and represents a progressive learning community both in terms of teaching and adopting technology.
Converged Access is a WLAN deployment mode that helps deliver common intelligent services across wired and wireless networks for security and policy, application visibility, network resiliency, smart operations and more. Catalyst 3850, Catalyst 3650, Catalyst 4500E switches, and Cisco 5760 WLAN Controllers (WLC) are capable of supporting Converged Access mode.

Location-based services have been getting a lot of attention lately and people are increasingly curious about how Wi-Fi and beacons play together in the hot space that is indoor location technology. In my last blog I reviewed how beacons work and how to differentiate when to use Wi-Fi and beacons. There’ve been some great questions about beacon technology and how it complements Cisco’s location-based Connected Mobile Experiences (CMX) solution, so I want to follow up on these topics with everyone.
What types of beacons are there?
Generally, there are two different classes of beacons: transmit only and backhaul enabled.
Transmit only beacons are exactly as they sound – they simply transmit information to anyone that is capable of hearing (bluetooth enabled smartphones). They do not receive or pass any data or information upstream.
Apple’s iBeacon is the best example of this type of BLE beacon. You can think of them like the navigational beacons used by airplanes when on approach to major airports. The beacon doesn’t even know the plane is there, but the plane is aware of the beacon and knows where the beacon is allowing it to take the correct action. Same is true for smartphones and transmit only beacons like iBeacon – the intelligence is located in the mobile application which must recognize the beacon and take appropriate action.
Backhaul enabled beacons generally include a Wi-Fi chipset for either management or data capabilities. Some backhaul enabled beacons are USB enabled and take advantage of whatever connectivity exists within the PC they are connected. Read More »

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 »
