E. 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 DKVM-IP8 installation is
from the test results with 3D-Labyrinth screen saver at Resolution 800x600, the worst case
consuming the highest network bandwidth.
