Unregulated Traffic
To maintain continuous maximum performance, we recommend that you do not share the RAVE network
with other computer network devices. Gaps are inserted between each data packet to make the network
robust to limited unregulated traffic. Recurring management traffic should not seriously affect the network,
but large computer file transfers would likely cause audio dropouts.
