D. Bandwidth Consumption
The preconfigured network speed selection simply results in a different Compression and Color
Depth configuration in order to match the different bandwidth limitations of the network type
(UMTS, ISDN, etc.).
The following suggested network bandwidth planning table for IP console installation is from the
test results with 3D-Labyrinth screen saver at Resolution 800x600, the worst case consuming
the highest network bandwidth.
