All-Digital DAS

Dali’s digital Distributed Antenna System (DAS) solution utilitizes Dali’s SDN Radio Router™ technology to transcend the capabilities typically associated with passive and active DAS in providing in-building and outdoor coverage and capacity. This revolutionary solution delivers more data throughput and is valued at the Total Cost of Ownership (TCO).

With Dali’s patented digital signal processing, the RF noise floor is unaffected by fiber length. This allows for greater coverage reach without signal degradation. With Dali’s all-digital and software-configurable solution, the entire network can be commissioned, upgraded and maintained through a Graphical User Interface (GUI). This eases installation and reduces deployment time.

Dali’s digital DAS system has a two-tier architecture consisting of the host (master unit) and a suite of remote radio units. RF signals are received from off-air, BDAs, base stations or any combination thereof. Dali uses a single optical transceiver for both uplink and downlink signals, which means that a single fiber can be used to transmit and receive signals using WDM, wave division multiplexing. In this way, the number of fibers required for any given deployment is reduced and this, in turn, reduces the cost of deployment and operation.

Also, with Dali’s digital DAS system, a transparent 1-Gbps Ethernet channel on each fiber connection can be used to carry IP traffic from Wi-Fi access points or other IP devices such as webcams, electronic messaging boards, digital announcement systems, surveillance cameras, or other IP-based equipment.
