Agile Wi-Fi Stadium Network Scores Big

Background

Amsterdam ArenA seats more than 68,000 visitors and has more than 17,000 parking spaces. It hosts European Cup soccer matches, American football games, concerts, and other events.

The owners wanted a Wi-Fi network covering the entire stadium grounds to offer rich valued-added services for spectators, staff, and V.I.P. users. Services included:

  • Video playback
  • Social media
  • Fan interaction
  • Internet access
  • Stadium management
Challenges

With the stadium’s huge size, varied user base, and need for so many value-added services, designers faced several challenges:

  • High user density: Achieving 100% coverage across the venue required a large number of Wi-Fi Access Points (AP) that caused severe interference affecting network capacity and user experience
  • Large network scale: Massive numbers of terminals connected to the stadium’s intranet made security tricky. In addition, heavy network traffic became a performance bottleneck for the wireless controller. Network reliability and scalability suffered
  • Varied terminals and services: The network had to handle dozens of different services operating on many different applications. High-quality service delivery and sufficient bandwidth for high-priority services, such as monitoring and video services, became problems

Solution

Huawei provided an agile network with S12700 Agile Switches and Ethernet Network Processor (ENP) cards with native access controller functions. The Agile Controller (AC) centrally managed and controlled network security and policies while offering all-around security collaboration and consistent service.

High-density wireless access

The network provides 100% signal coverage and connectivity for all spectators:

  • Each user has 512 kbit/s bandwidth
  • Each Huawei dual-band AP6510DN AP connects to 256 users simultaneously, allowing 50 spectators to use the same WLAN service (such as video) concurrently
  • AP6510DN APs work on both the 5 GHz and 2.4 GHz frequency bands and support 802.11n 2 x 2 Multiple In, Multiple Out (MIMO)
  • Huawei used small-angle 18º and 15º directional antennas and interference-suppression technologies, such as rate limit and CCA threshold optimization, to reduce interference. The APs are installed at least 37 ft. (11m) apart 
Agile Campus Solution tailored to the stadium

Huawei used S12700 Agile Switches for the campus core and Electroless Nickel Plating (ENP) high-density cards that included:

  • Support for more than 600 APs
  • AC functions and integration of wired and wireless parts of the network, making independent ACs unnecessary, eliminating performance bottlenecks
  • A 1.5G buffer to support millions of entries (1M MAC, 3M FIB, 256K ARP, and 64 Queue)

The ENP chip implemented centralized policy and service experience control by identifying user roles, terminal types, and terminal locations. It provided fine-granular control of access rights and service experience and offered higher bandwidth for V.I.P. users and stadium employees through a special group.

Huawei USG6650 Next-Generation Firewalls protected against external attacks. They could identify more than 6,000 applications and 100 protocol types, plus 85 million URLs. Rights and priorities were based on content and applications. Higher priorities were allocated to the official stadium website, the primary tenant (Ajax soccer team), and stadium applications. External videos and P2P services were assigned lower priorities or blocked.

Benefits 

  • Optimal service experience from a network offering 100% signal coverage and support for all concurrent users (25% of them can enjoy concurrent video)
  • ENP chips with native AC functions for innovative features
  • Wide ENP chip specifications for large-scale access requirements
  • SDN-based solution using centralized policy, service experience, and network security control to improve V.I.P. and key application service quality, greatly reducing deployment workload
  • Electroless Nickel Plating (ENP) high-density cards; the best choice for core switching gateways in large-scale networks
