This section describes how to calculate the required network bandwidth for a small-scale
configuration using three Pods.
Determine the maximum number of simultaneous mirroring devices connected to the main
unit and Pods beforehand as described in "Maximum number of simultaneous mirroring user
devices" (page 21) in the "Active Learning" section.
Also, determine the image quality and throughput for mirroring, Pod sharing, Skype for
Business integration, and streaming output beforehand as described in "Throughput when
mirroring from a user device to the main unit" (page 14) in the "Small-Scale Interactive
Lecture" section, "Pod sharing throughput between main unit and Pods" (page 24) in the
"Active Learning" section, and "Network bandwidth" (page 42) in the "Streaming Output"
section, respectively.
Next, calculate the network bandwidth that the wireless LAN access point and layer 2 switch
must maintain.
This description is for a system with expanded number of Pods and Skype for Business
integration, based on the example given in "Network bandwidth" (page 22) in the "Active
Learning" section.
The proposed configuration is listed below.
User devices connected to main unit or Pods: 6 (with image quality set to [High])

Pods: 3

Number of displays connected to the main unit: 2

Bandwidth used by Skype for Business integration: 4 Mbps (Up), 4 Mbps (Down)

Streaming output: Image quality set to [High]

Margin: 30%

For details about calculation equations, see "Network bandwidth" (page 22) in the "Active
Learning" section.
Network bandwidth that the wireless LAN access point must maintain
Calculate the total throughput corresponding to the red and orange arrows in "Small-scale
3-Pod configuration" (page 45).
