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 20) in the "Active Learning" section.
Also, determine the image quality and throughput for mirroring, Pod sharing, video
conferencing, and streaming output beforehand as described in "Throughput when mirroring
from a Windows device to the main unit" (page 15) in the "Interactive Lecture" section, "Pod
sharing throughput between main unit and Pods" (page 23) in the "Active Learning" section,
"Network bandwidth" (page 31) in the "Video Conferencing" section, and "Network bandwidth"
(page 33) 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 video conferencing, based
on the example given in "Network bandwidth" (page 21) in the "Active Learning" section.
The proposed configuration is listed below.
User devices connected to main unit and Pods

- Windows devices: 6 each (with image quality set to [High])
Pods: 3

Number of displays connected to the main unit: 2

Video conferencing: Bandwidth set to maximum value.

Streaming output: Image quality set to [High]

Margin: 30%

For details about calculation equations, see "Network bandwidth" (page 21) 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 35).
Calculation equation
Required bandwidth (T
× Number of Pods (N
+ Total throughput of user devices connected to main unit
= (6 Mbps × 1 + 1 Mbps × 5) × 3
+ (6 Mbps × 2 + 1 Mbps × 4)
= 49 Mbps
Adding the margin of 30%, 49 Mbps × 1.3＝63.7 Mbps
) = Total throughput of devices connected to each Pod
