Also, determine the image quality and throughput for mirroring, Personal Note Taker function,
Skype for Business integration, and streaming output beforehand as described in "Network
bandwidth" (page 31) in the "Large-Scale Interactive Lecture" section, "Network bandwidth"
(page 39) in the "Skype for Business Integration" section, and "Network bandwidth" (page 42)
in the "Streaming Output" section.
Next, calculate the network bandwidth that the wireless LAN access point and layer 2 switch
must maintain.
This description is for a system with added Skype for Business and streaming output, based on
the example given in "Network bandwidth" (page 31) in the "Large-Scale Interactive Lecture"
section.
The proposed configuration is listed below.
User devices mirroring: 6 (with image quality set to [High])

User devices using Personal Note Taker function: 100 (with image quality set to [High])

Number of displays connected to the Pod server: 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 31) in the
"Large-Scale Interactive Lecture" section.
Network bandwidth that the wireless LAN access point must maintain
Calculate the total throughput corresponding to the orange and purple arrows in the preceding
diagram.
Calculation equation
Required bandwidth (T
+ Total throughput of user devices using Personal Note Taker function
arrow)
= (6 Mbps × 2 + 1 Mbps × 4)
+ (6.4 Mbps × 100)
= 656 Mbps
Adding the margin of 30%, 656 Mbps × 1.3 = 852 Mbps
Network bandwidth that must be maintained between Pod server and layer 2 switch
Calculate the total throughput corresponding to the orange, purple, pink, and light blue arrows
in the preceding diagram.
