The Stadium Experience

Here are some of main points we have talked about during this recording:

Design

  • Designed for very high density (20K to 70K people)
  • Plan for 60%-70% of concurrently connected devices. In reality, you will see 40%-50% of concurrent connected devices.

Implementation

  • Different type of installation (overhead, underseat, through concrete…)
  • There are a lot of moving pieces
  • The process can take a long time and a lot can change in the meantime
  • A lot of challenges comes from things that you can’t account for ahead of time

Aruba in Stadiums

  • Client Match is useful in stadium deployments
  • They have done a lot of testing in the San Fransisco Football stadium in order to provide good configuration guidance

Wi-Fi Metrics to Follow

  • Number of connections per radio
  • Overall throughput in specific areas
  • Channel utilization (high is not necessary a bad thing)
