Wi-Fi Challenges in Large Venues –Blocking The Air
Sheer number of users congest the wireless medium to the point that the WLAN solution stops functioning
Many mobile devices WLAN drivers have a less-than-ideal implementation
30 to 40 thousand Probe Request packets per minute on a single channelWhen connected, the iPhone devices are twice as 'data hungry' as Android-based handsets for web browsing (see here)
Extricom Copyright © Confidential <6>
Wi-Fi Challenges in Large Venues –Additional Challenges
Venue bowls that were not initially designed for fixed Wi-Fi, or deployments at temporary events
Harsh physical environmentNo RF separation across the entire bowl at sports venues
Many reflections due to metal construction
Low link budget due to long distances between AP and mobile devices
HW equipment placement & operation effort of placing and cabling large number of APs & antennas
802.11 standard was not built for high density / large venues In March 2013, the IEEE802.11 has created a Study group for ‘High Efficiency WLAN’ (HEW SG) for addressing the massive challenges

Cell-Based Deployments Impose New Challenges
The whole concept is based on minimizing cell sizesResults in very costly projects of more then 1000 APsCreates challenges in placement of antennas and APs
Co-Channel interference between APs and between mobile devices and APsNaïve multicast implementation (critical for video and replays)No availability of multiple physical wireless networks for multiple usages
Standard fans vs. VIP, fans vs. administrative

Channel Blanket Technology
All Access Points operate on the same channel A single physical network (BSSID) covering the entire deployment areaFrom a Wi-Fi mobile device perspective, the entire Channel Blanket is detected as a single Access Point
Extricom Copyright © Confidential <10>
Channel Blanket Technology (Cont.)
The switch “hears” multiple copies of each client transmission through different APs
Chooses best copy and then picks best AP for reply transmissionsPerforms packet by packet optimization – clients always connected through an AP with best link quality and highest possible data rate
System partitioning Centralized WLAN switch implements all 802.11 MAC level functionality
UltraThin APs serve as a physical layer only - only radiosThe switch is actually a “mega-AP” extended with radios
Extricom Copyright © Confidential <11>
Channel Blanket Technology (Cont.)
Performance does not change regardless of the client’s locationAll channels are available at all locations
Blankets can be layered for increasing capacity and performanceUp to 4 blankets enabled by the same set of APs with 3 or 4 radios
Results with multiple channels in the same area, even within the same band
Separate blankets for isolating different traffic typesVIP fans on one blanket, the rest of the fans on another
802.11b clients on one blanket, 802.11g clients on another

Channel Blanket Technology -Simple to Deploy and Maintain
Simple site survey and deploymentNeed only to design for one variable – coverageOverlapping coverage of APs is actually beneficial• Ensures contiguous coverage• Adds system-level diversity
UltraThin APs have no firmware to upgrade, maintain or secure
Security is implemented at the switch
Layer 2 solution – no changes to the wired network VLANs or security

Extricom High Density Solution Concept
Dedicated WLAN switch designed for the LV scenarioMultiple Channel Blanket layers for stacking capacityHighly directional antennas for increasing link budget and coverage
The patented Channel Blanket architecture is much more immune to the harsh physical environment
Single BSSID over the entire venue on a single channel
Uplink diversity: same packet is received by multiple APs and then the best instance is chosen

Building Up a Deployment
Building a deployment from a single Channel Blanket up to a full system
The size of the area to be covered determines the number and type of antennas to be used
Extricom Copyright © Confidential <27>
Building up a Deployment (cont.)
1. The number of required antennas determines the number of required Access Points
2. Then, number of required Access Points determines the number of LV-2000 switches and their configuration
Extricom Copyright © Confidential <28>
Building up a Deployment (cont.)
Possible LV-2000 switch configurations supporting 2 channel blankets – 2.4 GHz & 5 GHz
1. Standalone – supporting up to 16 APs2. Switch Cascade - supporting up to 32 APs3. Large Scale – supporting up to 128 APs
Extricom Copyright © Confidential <29>
Antenna Types & Placement
Deploying APs in the most natural and straightforward location - provides both optimal coverage and ease of installation
Highly directional external antennas are used to provide best coverage and maximum link budget to mobile devices
Extricom Copyright © Confidential <30>
Antenna Types & Placement (cont.)
In closed arenas, Access Points and antennas are usually placed on existing infrastructure used for lighting and sound systems (catwalks)
Additional mechanical equipment is required to physically mount the APs and antennas to the existing infrastructure
Extricom Copyright © Confidential <31>
Scaling Up CapacityWith Multiple Channel Blankets
Going beyond 2 blankets requires stacking an overlay parallel combinations of switches & APs
The combinations of switches and APs cover the same venue deployment area while linearly increasing the overall capacity of the system
Advanced load-balancing schemes between Channel Blankets

Selected Customer Success Stories –Toyota Center (USA)
Extricom Copyright © 2013
We had the challenge of providing 3 full days of Wi-Fi in a verycrowded arena, guaranteeing VIP fans with specially secured, fully-reliable Wi-Fi throughout the event, numerous journalists dependent on us for their live, on-camera reports, and thousands of fans with smart phones and tablets. That’s a lot of pressure on any network
