Digital RF & Software defined Radio (SDR)

Holkirk’s DIF EDGE TERMINALS seamlessly integrate with Software-Defined Radio (SDR) modems, leveraging the DIFI (Digital Intermediate Frequency Interoperability) standard. This integration ensures interoperability and prevents vendor lock-in, enabling a more agile and scalable network.

By utilizing SDR modems, Holkirk’s terminals can dynamically adapt to various communication protocols, enhancing the overall efficiency and reliability of satellite communication systems.

Key Advantages of Holkirk’s DIF Technology

Resilience:

IP addressing simplifies the re-routing of signals within the digital domain, enhancing system resilience.

Security:

“Behind the fence” encryption safeguards sensitive equipment, such as encryption devices and modems, as well as personnel. This is particularly crucial when operating antennas in less secure regions, as Digital IF technology decouples antennas from coding equipment, thereby enhancing overall safety.

Flexibility:

Signal routing transitions to the IP domain, making the system modulation and encryption agnostic.

Virtual Network Functions (VNFs):

DIF interfaces with hardware functions like modems and spectrum analyzers can be deployed virtually via the cloud, transforming these functions from capital expenditures (CAPEX) to operational expenditures (OPEX).

Signal Quality:

Early digitalization of the signal in the RF chain ensures the preservation of signal quality, regardless of distance or the number of splits.
