Nextivity SHIELD EXTEND: Enterprise-Scale ERCES Solutions for Maximum Coverage
Emergency responder communications can determine the difference between life and death during critical situations. When first responders enter your facility, they need guaranteed radio coverage throughout every floor, corridor, and space. The Nextivity SHIELD EXTEND, delivered through MCA’s comprehensive public safety solutions portfolio, provides scalable Emergency Responder Communication Enhancement System (ERCES) coverage that combines Land Mobile Radio (LMR) and FirstNet capabilities in a single, code-compliant platform designed for enterprise-scale deployments.
What is the Nextivity SHIELD EXTEND?
The Nextivity SHIELD EXTEND represents a breakthrough in scalable public safety communications. This fully integrated ERCES solution delivers reliable in-building coverage for both Land Mobile Radio (LMR) 700/800 MHz bands and FirstNet Band 14, providing comprehensive emergency communications infrastructure in a single deployment.
Unlike traditional ERCES systems that require extensive manual configuration and lengthy approval processes, the SHIELD EXTEND leverages Nextivity’s proprietary IntelliBoost® technology to automate complex system parameters. This intelligent automation dramatically simplifies installation procedures while significantly increasing the probability of successful Authority Having Jurisdiction (AHJ) inspection on the first attempt.
The system’s modular architecture supports facilities ranging from single buildings to expansive campus environments, with Power-over-Ethernet (PoE) distribution enabling distances up to 325 feet between Network Units and Coverage Units. For larger installations, optional Fiber Range Extenders can extend this range to nearly one mile, making SHIELD EXTEND ideal for high-rises, campus facilities, and multi-building complexes where traditional ERCES solutions face deployment challenges.
Advanced Technology Platform and Automation
IntelliBoost® Intelligence for Guaranteed Performance
The SHIELD EXTEND platform incorporates Nextivity’s advanced IntelliBoost processing chip, which delivers unparalleled automation capabilities that transform the traditional ERCES deployment experience. This proprietary technology automatically calculates and optimizes critical system parameters, including uplink gain, downlink gain, path loss calculations, and system isolation measurements.
The system’s real-time monitoring capabilities continuously adapt to environmental changes, ensuring consistent performance throughout the facility’s operational life. This intelligent adaptation eliminates the need for manual testing equipment during commissioning and significantly reduces the potential for installer error, directly contributing to faster AHJ approval and certificate of occupancy issuance.
Dual-Mode Class A and Class B Flexibility
One of the SHIELD EXTEND’s most significant advantages lies in its software-configurable operating modes. The system can be configured as either Class A (channelized operation supporting 56 channels at 12.5 kHz bandwidth) or Class B (wideband operation supporting 28 channels at 100 kHz or 150 kHz bandwidth) directly in the field without requiring additional license fees or hardware modifications.
This unprecedented flexibility enables building owners and contractors to adapt their ERCES deployment to meet the specific requirements of different jurisdictions without maintaining separate equipment inventories. The ability to reconfigure the system as local codes evolve provides long-term investment protection and operational flexibility.
