Reliable In-Building Communications Public safety communications are a vital part of emergency services operations, from dispatch to mission-critical situations, and from voice-only capabilities to voice and data. Over the years, public safety communications have evolved from simple fire call boxes to analog land mobile radios (LMR), to digital LMRs and trunked radio systems. Today the evolution continues with a shift to multi-mode communications combining LTE, data communications such as email, apps and VoIP, and IoT, enabling new technical appliances such as sensors, infrared, location mapping...

The system is software-configurable and supports both FirstNet and LTE waveforms ensuring a smooth transition from P25 Phase I and II to LTE. The system has a simple and flexible modular architecture consisting of headend units that can accept base station or off-air feeds, an optional digital aggregation/distribution unit, medium and high power remote radio units (RRUs),...

Self Healing Futureproof Technology Advanced Digital Signal Processing The Avari VL™ Series uses advanced digital signal processing to transform analog RF into high-quality digital signals. This minimizes noise interference and signal degradation during transport contributing to lower noise floor rise at the radio frequency (RF) source and ultimately providing higher quality and more reliable radio communications. New RF sources can now be added without introducing passive intermodulation (PIM). Lossless Digital Transport Avari’s lossless digital transport ensures that signals retain their quality...

The Avari VL™ Series supports both current and future public safety communications requirements and streamlines the transition. Network owners can install an Avari VL™ network today, then expand and upgrade in the future without having to ‘rip-and-replace’. • Field Programmable Gate Array (FPGA) chipsets execute the advanced digital signal processing. These devices can be reprogrammed or upgraded by simply uploading a new image file to accommodate new waveforms or implement new standards. • RF modules are pluggable and the system is reconfigurable. New RF band modules can be easily added later...

Flexible Fiber Topology Avari’s approach to fiber topology is key to helping Avari's VL™ deployments achieve a low total cost of ownership. Its all-digital architecture enables multiple network topologies including star, chain and hybrid configurations. These cater to different deployment scenarios, help to reduce fiber plant usage and installation costs, and also facilitate effective redundancy configurations. With the ability to cascade host units, Avari VL™ can support centralized headend architectures and can easily enable new RF sources from different locations to be incrementally added to the...

VL™ Direct Master Unit (VL-DMU™) The VL-DMU interfaces with Base Stations (BTS) or Bi-Directional Amplifiers (BDA) over analog RF. It converts signals from analog RF and digital data packets and intelligently routes the digital signals through the VL-DMU or directly to/from the remotes. The VL-DMU processes up to four public safety RF bands simultaneously. The VL-AMU 33/37 are integrated off-air/-headend units designed for off-air interfacing to public safety base stations. The VL-AMU 33 is a dual or tri-band unit and the VL-AMU 37 is a tri-band unit that respectively filters and amplifies RF...

The VL-DU 8/14 is a digital aggregation distribution unit that receives digital data streams from one or more host units and distributes the data to multiple remote units. The VL-DU also works as an optical port expansion unit featuring 8 or 14 independent optical fiber interfaces. The VL-RU 33/37 are mid-powered and high-powered remote radio units that process up to 3 RF bands simultaneously. Its pluggable RF band modules have RF output power of 2W and 5W per band respectively. Convection cooled, the units offer quiet operation and high Mean Time Between Failure (MTBF). The VL-CLK has a built-in...
