Dali Wireless’ RF Router® System is Industry’s Most Advanced Digital-Over-Fiber Solution for...

Extending Wireless Carriers' Coverage and Capacity


Palo Alto, CA (August 2, 2013) – Dali Wireless, Inc., today introduced the industry’s most advanced digital-over-fiber solution for delivering distributed wireless coverage and capacity. Based on the company’s t-Series™ RF Router system, it has the industry’s lowest cost of ownership while providing 6 times the reach, 3 times the bandwidth, and requiring 1/3 the fiber, 25% less power, and 75% less equipment space. Dali Wireless will demonstrate the network at the 2013 Wireless Infrastructure Show (October 7th to 10th, Hollywood, Florida, in Booth 713/715).


The Dali system extends the coverage and capacity of signals from wireless carriers indoors and outdoors in almost any environment. Its integrated RF signal routing architecture brings intelligence to every element in the network. The solution employs advanced RF, digital, networking, and optical technologies rather than incrementally building on outdated distributed antenna system (DAS) concepts. Dali’s innovative system is the result of decades of technical experience and its underlying technologies are covered by more than 100 patents. Exploiting these technologies makes it possible for Dali to increase efficiency, reduce hardware size, and significantly reduce total cost of ownership.


Primary components of the t-Series include the tHost® units, quad-band t30™ low-power remote transceivers for indoor applications, quad-band t43™ high-power remote transceivers for outdoor applications. Software options include a comprehensive network management and an advanced capacity management systems. All network functions as well as adding new hardware or features and capacity re-allocation are orchestrated from a single point via a modern user interface either locally on a PC, via Ethernet, or virtually anywhere via a Web browser. The solution is manufactured in North America and meets FCC masking specifications, UL, CE, and NEBS standards.


Broad Operator Bandwidth, Greater Reach


With an instantaneous bandwidth of 164 MHz in both the uplink and downlink paths, the system can simultaneously accommodate every active band (700, 850, 1900, and 2100 MHz) used by the four major wireless carriers, with bandwidth remaining to provide network backhaul at 1 Gb/s as well as Wi-Fi capability. Wi-Fi traffic is completely isolated from the cellular network signals to ensure security. The system is also available in 900, 1800, 2100, and 2600 MHz for other international markets.


Signals remain in the digital domain throughout the system with no signal degradation regardless of network size, which can be up to 40 km from the head-end to the furthest remote — 6 times greater than any analog-over-fiber system. In addition to star and hybrid configurations, the Dali system can daisy-chain remotes one after another, eliminating the need for multiple fiber runs to serve all the remotes. This significantly reduces system cost as less fiber and other hardware are required for a given system, and increases overall reliability.


Advanced Capacity Management


Dali’s advanced capacity management (load balancing) functionality is one of the most innovative capabilities that differentiate its system from all others. The system can dynamically allocate network capacity, on demand, to any point in the system without dropping calls or data sessions via its user interface.


Any signal in any band from any carrier can be connected to any remote under software control without hardware changes or cable-swapping typical of conventional systems. Capacity re-allocation can be performed automatically, based on known events that occur regularly, or can be performed at any time by the operator when traffic changes occur.


Dali’s advanced capacity management enables a cloud-like architecture where base station resources can be pooled together into one “base station” farm at any remote location. Over-provisioning is no longer necessary since additional base station resources can be augmented seamlessly to the base station farm at any time in the future.


Dedicated Carrier Resources


The Dali system is designed to provide wireless carriers and neutral hosts with total control of their resources. Unlike many systems, the t-Series dedicates one tHost unit to each wireless carrier, so while the total traffic from all carriers on the network is combined and transmitted through the same fiber, each carrier’s resources are completely independent from the others. This ensures that each one is treated fairly in terms of RF output power and other functionality.


Future-Proof Scalability


The t-Series system is designed for easy expansion. For example, if additional remotes need to be added after a system is deployed, they are simply connected within the network using SFP connectors in “plug-and-play” fashion. The management system will then immediately recognizes their presence and add them to the network. Likewise, additional frequency bands can also be simply added to an existing system as required.


Strong System Reliability


System reliability is ensured via Dali’s optical bypass switch which immediately takes a malfunctioning remote offline and routes signals around it so the network can continue to function. In addition, Dali’s optical bypass switch also allows for easy replacement of any failed remote without any down-time in the network.


Availability


The complete Dali RF Router system as well as all t-Series products are available now, and the company provides comprehensive resources to support them including on-site training, 24/7 technical support, and other services.
