Virtual Fronthaul Interface (vFI™)

Dali Matrix^® Virtual Fronthaul Interface (vFI™) transforms the traditional two-tier fronthaul architecture which employs a point-to-point connection between the Baseband Unit and the Remote Radio Unit to a three-tier multipoint-to-multipoint network that is driven by software.

By adding an additional tier which implements advanced radio signal routing, aggregation and translation capabilities to the fronthaul network, Dali vFI enables shared infrastructure, dynamic capacity allocation, and more importantly, an open RAN.

This three-tier architecture creates a more competitive and innovative ecosystem where mobile operators have the option to select the best-in-class RAN elements that not only meet their current network requirements but the varying 5G applications and deployment scenarios in the most cost-effective and efficient way.

Dali Matrix^® Virtual Fronthaul Interface (vFI™)

• Interface between Baseband Unit (BBU) or virtual base station (vBS) and Remote Radio Unit (RRU)
• Ability to manage CPRI and non-CPRI transport protocol on a fronthaul interface
• Conversion of Ethernet frames to CPRI/eCPRI/RoE using x86 processors
• 8 (or 16) x 10 Gbps optical interfaces
• 4 x 1 Gbps Ethernet interfaces
• Programmable software platform for easy upgrades
