SHIELD SOLO

Class A or Class B Code Compliant 0.5W ERCES Public Safety BDA

Regions: United States
LMR: 700/800 MHz

The SHIELD SOLO sets a new benchmark for low-power emergency responder communication enhancement systems (ERCES). Combining uncompromising performance with industry-leading ease of installation, speed of deployment, and remote system monitoring and management capabilities, SHIELD SOLO ensures reliable connectivity for emergency personnel and allows building owners to receive their certificates of occupancy (CoO) faster than with any other solution in its class.

ERCES Public Safety DBA

The New Standard for Low-Power ERCES

Better Performance, Faster Installation

Leveraging Nextivity proprietary IntelliBoost technology, SHIELD SOLO brings the industry-leading features and capabilities found in the Nextivity SHIELD EXTEND public safety DAS to the low-power ERCES market. With so much advanced technology packed into a single-box solution, SHIELD SOLO gives business owners the fastest pathway to getting an ERCES installed, receiving Authorities Having Jurisdiction (AHJ) approval, attaining their CoO, and opening the doors to their business.

  • NO NOISE Guarantee – Set Uplink and Downlink Gain based on automatic isolation measurements
  • Automatically adjusts Uplink Transmission Power
  • Industry’s most robust solution to combat Near-Far Problem (we can hear it all)
  • Talk-Out Guarantee – Industry’s first Uplink Test using consumer two-way radios
  • Unparalleled real-time Talk-In / Talk-Out Performance
  • Antenna monitoring with Active Server Antennas

Removing the Guesswork

Nextivity proprietary IntelliBoost technology inside SHIELD public safety solutions enables them to automate system parameters — something no other ERCES can do. By automatically calculating and setting system parameters, SHIELD SOLO allows installers to install an ERCES faster and with more confidence it will pass the first AHJ inspection than with other solutions.

  • Real-time monitoring of environmental changes and automatic adjustments (if necessary) to ensure consistent, reliable performance
  • Automatic setting/optimization of uplink (UL) gain (no additional testing equipment or calculation guessing)
  • Automatic calculation of path loss, allowing for different values according to network requirements
  • Isolation calculated in real-time and automatically set at 20 dB per NFPA 1221 (the system also allows for different values according to local ordinances)
  • Downlink (DL) gain automatically adjusted to achieve required value

System Components

SHIELD SOLO

The core of the system, SHIELD SOLO is a bi-directional amplifier (BDA) that accepts LMR donor signals and distributes the signals to antennas throughout the building. The system is ideal for buildings in jurisdictions that require code compliant public safety communication solutions, including offices, schools, warehouses, and more.

  • 0.5W per band for channelized 700 MHz and 800 MHz LMR bands
  • Class A or Class B software selectable in the field without additional codes or license fees
  • Proprietary IntelliBoost software for industry-leading automation features
  • Built-in, end-to-end remote system monitoring and management via the WAVE Portal
  • Compatible with optional Nextivity SHIELD components or third-party ERCES components
Model Number: L41-7EB

SHIELD SOLO Battery Backup Unit (BBU)

The SHIELD BBU provides constant direct current and battery charging capabilities for SHIELD SOLO systems, which allows the solution to maintain peak operation for up to 12 during power outages.

  • Keeps SHIELD SOLO and system accessories operational for up to 12 hours in the event of a power failure
  • Supports 80Ah / 12V lead-acid batteries
  • Two alarm ports for BBU monitoring
Model Number: L44-00

About the SHIELD SOLO

SHIELD SOLO

Class A or Class B Code Compliant 0.5W ERCES Public Safety BDA

SHIELD SOLO is a half-watt ERCES that can be configured as Class A or Class B to support a wide range of jurisdictions. The system combines uncompromising 700/800 MHz LMR coverage with industry-leading ease of installation, speed of deployment, and remote system monitoring and management capabilities. Built with Nextivity proprietary IntelliBoost software, SHIELD SOLO offers advanced automation features that calculate and set system parameters. This not only enables the fastest pathway to get an ERCES installed and approved by the local AHJ, but also streamlines the process for building owners to receive their CoO as quickly as possible.

Optional Components

SHIELD Remote Annunciator

The Remote Annunciator Panel (RA) provides automatic supervisory signals for malfunctions of SHIELD SOLO solutions. In addition to being NEMA 4 rated and complying with NFPA and IFC fire codes, the RA features PoE architecture for quick installation and alarm configuration. The RA also offers real-time component monitoring through the WAVE Portal.

Model Number: F42-10R-100
