For reference, a sample calculation is described for the following conditions.
User devices mirroring: 2 (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 main unit: 1

Margin: 30%

Required bandwidth = 6 Mbps × 1 + 1 Mbps × (2 – 1) + 6.4 Mbps × 100

= 647 Mbps

Adding the margin of 30%, 647 Mbps × 1.3 = 841.1 Mbps
If joining an existing network, it is necessary to consider whether there is surplus bandwidth
available for Vision Exchange from the existing bandwidth usage. If necessary, enhance the
network infrastructure, for example by adding wireless LAN access points.
If the required network bandwidth cannot be maintained, reduce the number of simultaneous
connections, or set the image quality to Mid or Low to reduce the bandwidth usage for Vision
Exchange. Note that the resulting picture will be degraded if the image quality setting is
reduced.
