Notched frequenciesParts of the frequency band can be blocked (notched) within the PowerLink IP system's channel band.

Allows higher data rates due to the extension of the PowerLink IP frequency band beyond blocked frequencies that are, for example, used by radio services.

PowerLink IP – Smart Frequency ManagementSmart frequency management and efficient bandwidth utilization

Asymmetrical data streamsPowerLink IP’s data upstream and downstream channels can be adjusted to different bandwidths.

Enables the data throughput to be adapted to the special requirements of modern grid applications.

Channel spreadingIf part of the PowerLink IP frequency band is disturbed, additional frequency bandwidth can be requested from adjacent PowerLink IP systems. Systems operating in adjacent channels automatically exchange information about the individual bit rate to be transmitted and optimize the band utilization for all systems operating in neighboring frequency bands.

Ensures maximum data throughput for all PowerLink IP systems in the event of external disturbances.
