SHIELD EXTEND Components
Management Unit
The SHIELD EXTEND Management Unit (MU) is the central point of the system. In addition to accepting and distributing power from the SHIELD EXTEND Battery Backup Unit (BBU), the MU controls and monitors all system components, including the Network Unit (NU) and Coverage Unit (CU) as well as SHIELD Remote Annunciator Panel (RA), Emergency Power-off Switch (EPO), and Active Server Antennas. System performance analytics are available in the Nextivity WAVE Portal or WAVE PRO app.

Network Unit
The head-end of SHIELD EXTEND installations, the Network Unit (NU) processes and digitizes separate off-air LMR and FirstNet donor signals and distributes those signals to the system’s Coverage Units (CUs). Providing coverage up to 320K ft² per CU, each NU can support and power up to six CUs via scalable PoE architecture.

SHIELD EXTEND Fiber Range Extender (FRE)
Ideal for campuses, multi-building facilities, and high-rises, the SHIELD EXTEND Fiber Range Extenders (FREs) increase the distance between the Network Unit (NU) and Coverage Unit (CU) up to 1.4 kilometers in SHIELD EXTEND installations. In addition to supporting copper cable to power up CUs remotely, FREs work in pairs and are sold as a kit that includes two units—one NU side and one CU side—with each pair supporting up to two CUs.
Model Numbers:
_ › NU Side: F40-0XNU
_ › CU Side: F40-0XCU
SHIELD Remote Annunciator (RA)
The SHIELD Remote Annunciator Panel (RA) provides automatic supervisory signals for malfunctions of SHIELD ERCES public safety 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 with SHIELD installations. The RA also offers real-time component monitoring through the WAVE Portal.
Model Number:
_ › F42-10R-100
SHIELD Emergency Power-Off Switch (EPO)
The SHIELD Emergency Power-Off Switch (EPO) instantaneously shuts down SHIELD ERCES public safety systems from a single point, eliminating the risk of combustion caused by electricity or static. The EPO is designed to prevent inadvertent operation and can be installed in any location designated by the local Authority Having Jurisdiction (AHJ). In addition to being NEMA 4 rated and complying with NFPA and IFC fire codes, the EPO features PoE architecture for a quick installation and configuration with SHIELD ERCES installations.
Model Number:
_ › F42-10E-100
SHIELD Active Server Antenna
The SHIELD Active Server Antenna is an active multi-frequency, omni-directional antenna for ERCES public safety solutions that require monitoring capabilities at the component level. In addition to being designed for hard cap and false ceilings, the Active Server Antenna features an N-type female connector and rugged IP20 grade electronics. The component is ideal for SHIELD ERCES installations, which provide real-time antenna monitoring capabilities through the Nextivity WAVE Portal.
Model Number:
_ › A33-10A-100
Tools and Software
WAVE Portal
The WAVE Portal is a cloud-based remote management platform that enables device management and maintenance of SHIELD ERCES systems. The WAVE platform is designed to also work on mobile phones which facilitates ease of use on site.
More Details
The SHIELD EXTEND Class A or Class B 700MHz/800MHz channelized Emergency Responder Communications Enhancement System (ERCES) public safety solution was designed with the needs of First Responders, Building Owners, Installers, and Authorities Having Jurisdiction (AHJs) considered. SHIELD EXTEND is a complete solution, each component fully-compliant with the current International Fire Code (IFC) and National Fire Protection Association (NFPA) standards.
As the public safety community evolves to include cellular LTE support, the SHIELD EXTEND is the only solution that offers true carrier-grade channelized support for FirstNet. Both LMR and LTE aggregated at the head-end, digitally-distributed over Category cable, and retransmitted through a single serving antenna or DAS field.
SHIELD EXTEND is the first and only solution in the market that can easily be scaled from a single donor “BDA” deployment at 1 or 2 watts to a full-blown (single donor) “Fiber DAS” up to 6 watts.
SHIELD EXTEND is best-in-class with 56 individually configurable channels on the Class A unit and 28 channels with 100Khz and 150kHz bandwidth options on the Class B variant (700MHz and 800MHz) and 1W downlink per Coverage Unit (CU) per band. Best-in-class channelized uplink squelch and micro-processor controlled automatic gain control (AGC) per time-slot, inherited from Nextivity’s carrier-grade LTE technology platform, unconditionally guarantees no interference to base stations and optimizes signal quality.
SHIELD EXTEND includes all standard alarms, supports all NFPA and IFC-required monitoring, and connects to Nextivity’s carrier-grade, SOC 2 (Type 1)-certified WAVE portal, providing best-in-class on-demand remote monitoring, not just for standard alarms but also to ensure system KPIs.
Where competing products require integrators to purchase pieces and parts from a variety of vendors to create a complete solution, SHIELD EXTEND offers everything from the head end (Network Unit or NU), remotes (Coverage Unit or CU), Battery Backup Unit (BBU), Remote Annunciator, Emergency Power-off Switch (EPO), and an As-Built Box. All the components are NEMA 4X rated and optimized together.
No Noise Guarantee
By monitoring environmental changes and performing automatic adjustments, SHIELD EXTEND ensures emergency personnel stay connected in any situation by delivering industry-leading performance with a no noise guarantee.
Automatic Setting of Uplink Transmitted Power
SHIELD EXTEND simplifies the optimization of uplink (UL) gain for emergency communication systems by eliminating the need for additional equipment or guessing the calculations. The system calculates path loss automatically, allowing for different values according to network requirements and the option to setup a target range.
Automatic Calculation and Setting of Isolation & Downlink Gain
While isolation is calculated in real-time and automatically set at 20 dB per NFPA 1221, the system allows for different values according to local ordinances. DL gain is automatically adjusted to achieve the required value.
Industry-First Talk-Out Guarantee
SHIELD ERCES solutions’ groundbreaking uplink (UL) test allows integrators to easily achieve industry-leading talk-out performance by measuring the signal traveling from the installation site to the remote tower via walkie-talkie. Using COMPASS XR and the WAVE PRO app, installers can test UL gain levels and view real-time analytics to ensure the best-possible signal-to-noise ratio.
Built-in Grid Test Functionality
With WAVE PRO and COMPASS XR, system integrators can test the downlink (DL) gain for the design planning stage and post-install performance evaluation. Export the Full Signal Report as a .csv, which includes key LMR/Operator Network parameters: Operator, RSSI, RSRP, RSRQ, Frequency, Band, PCI and more. Installers use system operation data to prepare for AHJ walk-through tests.
Built-in End-to-End Remote System Monitoring and Management
The web-based WAVE Portal provides installers and authorized users remote monitoring, managing, and control of SHIELD ERCES systems from anywhere. In addition to easily adapting SHIELD systems to local fire codes, the WAVE Portal allows users to customize notification and policy parameters. The intuitive platform also offers advanced performance metrics on individual SHIELD components, including real-time high site-to-server antenna monitoring and donor signal quality reports.
