Dali Matrix^®

Dali Matrix^® is a compact, next generation digital DAS platform that provides intelligent wireless signal routing and coverage for cellular, public safety and Wi-Fi, over one single transport infrastructure.

It has a fully modular two-tier architecture that includes a plug-and-play integrated headend unit and low and high power remote radio units (RRUs). Remote reconfiguration through the internal Matrix Element Management System™ facilitates network scaling that leverages existing infrastructure to keep costs and risks low.

Its simultaneous provision of cellular and public safety fronthaul and IP backhaul supports both C-RAN and D-RAN hybrid networks enabling operators to dynamically deliver capacity to hot-spots in the network.

Dali Matrix accommodates multiple mobile operators, transport technologies, base station vendors and global frequency bands.

Dali Matrix Highlights:

• Plug-and-play modules
• Software configurable
• Supports base station RF interface with power input of up to 100 W
• Supports multiple CPRI, ORI, and OBSAI bit rates; and in the future also RoE, eCPRI and NGFI
• Single optical fiber with digital throughput of up to 10 Gbps
• Up to 320 MHz of aggregated RF bandwidth per wavelength
• Supports global frequency bands
• Accommodates 1 Gbps or higher Ethernet backhaul

Dali Matrix in Action

Dali Matrix^® Universal Base station Interface Tray (UBiT™)

The Dali Matrix platform has a simple, modular, two-tier architecture that includes the Universal Basestation Interface Tray, UBiT™ with plug-and-play modules, and the hd30™ and hd43™ remote radio units.

The modular integrated headend UBiT supports both analog RF to base stations (BTS) and digital interface to baseband units (BBU) and virtual base stations (vBS). On the downlink (DL) path, the UBiT receives RF signals from the BTS and then it converts to digital data streams. Other digital baseband data and third party IP data can also be aggregated and transported to remote locations. This process is reversed for uplink (UL).

Universal Basestation Interface Tray (UBiT) – Modular Integrated Headend
The compact UBiT has an integrated controller and power module and 12 universal ‘plug-and-play’ component slots.

Integrated Controller and Power Module (UBiT-CP)
Detects and provides power to all modules placed in the UBiT chassis, and monitors voltage and power consumption of the modules

RF Conditioner Module 37 (UBiT-RFC37) – low power
Provides signal conditioning via gain adjustment and band appropriate filtering for communication with other UBiT modules. Maximum input power of 5 W

RF Conditioner Module 50 (UBiT-RFC50) – high power
Provides signal conditioning via gain adjustment and band appropriate filtering for communication with other UBiT modules. Maximum input power of 100 W

Splitter-Combiner Module  (UBiT-SC)
Splits / combines RF signals at up to a 1:4:1 ratio as required on the uplink and downlink between the Conditioner and Host modules

Quad-band Host Module (UBiT-hdHost)
Converts signals from analog RF to digital data packets and intelligently routes the digital signals to / from the remotes via 8 optical interfaces

Virtual Fronthaul Interface Module (UBiT-vFI™)

Accepts digital content from baseband units and/or virtual base stations (vBS) and intelligently routes the signal to multiple remote radio units

Digital Distribution Unit Module (UBiT-DDU)

Receives digital data streams from host and/or vFI modules and re-distributes the same digital content to multiple remote radio units

Remote Radio Units (RRUs)

hd30™ Low power remote
Processes up to 4 RF bands simultaneously, has a data rate of 10 Gbps and can accommodate 1Gbps Ethernet backhaul. Pluggable RF band modules have RF output power of 1W per band

hd43™ High power quad-band remote
Processes up to 4 RF bands simultaneously, has a data rate of 10 Gbps and can accommodate 1Gbps Ethernet backhaul. Pluggable RF band modules have RF output power of 20W per band.

Can be mounted in pairs for an eight-band installation.

Control and Management

Matrix Console™
Centralizes and simplifies the management and control of the Dali Matrix system

Matrix^® Element Management System™
Standard web browser based user interface provides full insight into and control over the radio distribution network. In multi-operator environments, access management ensures fully segregated and secure access and control for each participating operator
