Dali Matrix® (Matrix) is a unified RF distribution platform capable of delivering cellular, public safety and Wi-Fi services over the same transport infrastructure. Its simultaneous provision of cellular and public safety fronthaul and IP backhaul supports both C-RAN and D-RAN hybrid networks enabling mobile operators to cost effectively and dynamically deliver capacity to hot-spots/zones in the network.
The Dali Matrix® platform has a simple, modular, two-tier architecture that includes the Universal Basestation Interface Tray, the UBiT, with plug-and-play modules, and the hd30 and hd43 remote Radio Units. It is remotely configurable, enabling mobile operators and enterprises to easily scale their networks while leveraging existing investments to keep both costs and risks low. It also provides great design flexibility, accommodating multiple mobile operators, technologies, base station vendors and frequency bands in a “mix-and-match” fashion.
This fully software configurable next generation platform is controlled through the Matrix Element Management System™ (Matrix EMS™). With its easy to use web interface, the Matrix EMS gives mobile operators full insight into, and control over, their radio distribution network. In multi-operator environments, first class access management enables fully segregated and secure access and control for each participating operator.

The Universal Basestation Interface Tray, the UBiT, is a modular and software configurable headend unit. It supports up to 12 universal slots that house various plug-and-play modules. The modules can be inserted and configured as needed, supporting any mix of RF or digital baseband inputs.
The UBiT is an integrated headend unit with a Controller and Power module. Plug-and-play modules includes RF Conditioning modules, Active Splitter-Combiner modules, Base Band Interface modules and Quad-Band host modules.
On the downlink (DL) path, the UBiT receives RF signals from the base stations (BTS). The RF signals are then converted to digital data packets. Other digital baseband data and third party IP data can also be aggregated and transported via fiber optic link to the modular radio units at data rates of up to 10Gbps.
On the uplink (UL) path, the UBiT performs the reverse functions delivering the signals back to the corresponding base stations either as RF or as digital baseband signals, and the IP data to the Internet backbone.
Monitoring and control can be performed locally or remotely via the UBiT’s web browser based Element Management System (EMS) or through a Network Management System (NMS) using SNMP.

The Controller and Power module manages operation, monitoring and control of the UBiT modules. It enables the local or remote management of the network via the Element and Network Management Systems and converts and provides the necessary DC power to all the other UBiT modules.
The RF Conditioner module has a maximum input power of 100 W (UBiT-RFC50) or 5 W (UBiT-RFC37). The RF Conditioner module supports fast ALC (automatic level control) on the DL path with a remotely configurable threshold. Any DL input power above the assigned power threshold will trigger the ALC circuit to protect the downstream RF path, automatically clamp the signal, and activate an alarm.
The Active Splitter-Combiner module combines up to 4 independent DL signals coming from the RF Conditioner modules, and 1:4 splitting of UL signal coming from the host module.
The Baseband Interface module (BBI) has 8 optical interfaces that accept standard industry protocols (CPRI, OBSAI, etc) from the BBU at a rate of up to 10 Gbps. The optical interfaces can also deliver the aggregated information to the host module or other BBI modules. Multiple BBI modules can be cascaded to increase processing capability and the total number of optical interfaces.
The Quad-Band Host modules receive conditioned RF signals from the BTS. The RF signals are then converted to digital data streams. Other digital baseband data and third party IP data can also be aggregated and transported to remote locations.
The hd30™ is a low power modular radio unit that can process up to 4 RF frequency bands simultaneously. hd30 is connected to the UBiT unit over a single optical fiber link with a data rate of
10 Gbps and an optical link budget of 15 -30 dBo. It can also accommodate a 1 Gbps or higher IP backhaul over 4×1 Gbps Ethernet interfaces with (Power over Element) PoE.
On the DL path, hd30 receives the digital data stream from the UBiT and converts the signal back into RF for transmission over the antenna.
On the UL path, hd30 converts the RF signal into a digital data stream and transports the signal over a single optical fiber to the UBiT unit. The hd30 can process an aggregated RF bandwidth of up to 320 MHz on uplink and up to 320 MHz on the downlink path.
The hd30 can be connected to the UBiT in a star, daisy chain, or hybrid star/daisy chain configuration. Dali’s ability to support multiple topologies enables greater system design flexibility, and reduces fiber requirements and installation costs.
The hd43 is a high power modular radio unit. The hd43 can process up to 4 RF frequency bands simultaneously and transport data over a single optical fiber at a data rate of 10 Gbps. It has an optical link budget of 15 – 30 dBo and can accommodate 1 Gbps or higher Ethernet backhaul via 4 Ethernet interfaces with PoE.
On the DL path, hd43 receives the digital data stream from the UBiT and converts it back into RF for transmission over the antenna.
On the UL path, hd43 converts the RF signals into digital data streams and transports the signal over a single optical fiber back to the UBiT. hd43 can process an aggregated RF bandwidth of up to 320 MHz on uplink and up to 320 MHz on the downlink path.
The hd43 can be connected to the UBiT in a star, daisy chain, or hybrid star/daisy chain configuration. Dali’s ability to support multiple topologies enables greater design flexibility, and reduces fiber requirements and installation costs.
During installation, two hd43s can be mounted side by side thereby achieving an eight-band installation with two quad-band hd43s.
The Matrix Element Management System (Matrix EMS™) gives operators real time visibility, monitoring and control of network performance right through to the fronthaul. Operators are able to monitor network alarms, control components such as conditioner modules, and view signal traffic flow.
In multi-operator deployments, the revolutionary Matrix EMS gives the ability to view full network performance, including of the entire fronthaul through to the radios, to all participating operators on a per operator basis.
Within the Matrix EMS, lead operators, integrators, and neutral hosts have the ability to provide each participating operator with an operator specific domain for monitoring and control of relevant network components and traffic. Access is via a unique URL and web-based interface, and is fully segregated and secure. Participating operators gain alarm monitoring access to the full network, control access to their dedicated components such as conditioner modules, and are even able to view signal traffic flow.
