XWJ2-SJ | INDOOR SPECTRUM JAMMER
The unival XWJ2-SJ | INDOOR SPECTRUM JAMMER is a compact, high-performance indoor jammer for the targeted suppression of 5G and Wi-Fi communications. The system is based on a modular 10- channel design and can be individually configured for each location based on a local spectrum fingerprint.
FEATURES & BENEFITS
SPECTRUM-FINGERPRINT-BASED CONFIGURATION
System configuration is based on on-site RF spectrum analysis, enabling precise and location-specific signal suppression instead of broad, non-targeted emission.
MODULAR ARCHITECTURE – UP TO 10 JAMMING MODULES
One main unit supports up to 10 independent jamming modules. Multiple units can be combined for complex or large-scale installations.
ADJUSTABLE OUTPUT POWER PER MODULE
Output power adjustable per module up to 2.5 W, with four discrete power levels (200 mW to 2.5 W) for precise adaptation to room size and shielding requirements.
POWER OPTIMIZATION VIA MODULE STACKING
Higher jamming effectiveness within a specific frequency band can be achieved by operating multiple modules in parallel on the same band.
REMOTE FINE-TUNING AND REAL-TIME ADJUSTMENT
LAN-based remote access enables real-time parameter adjustments and rapid response to changing RF conditions during operation.
ROBUST, SERVICE-ORIENTED MECHANICAL DESIGN
Anodized aluminum housing with integrated key lock, status LEDs, concealed service access, and VESA-compatible mounting options.
INTEGRATION WITH UNIVAL SPECTRUM GUARD (USG)
Seamless integration with USG enables real-time RF detection and spectrum analysis to further enhance jamming efficiency and operational control.
MODULAR HIGH-PERFORMANCE JAMMING UNIT
Compact, high-efficiency modular jamming system designed for controlled and secured environments such as correctional facilities and judicial buildings.
WIDE FREQUENCY COVERAGE (MODULE-DEPENDENT)
Each module can be configured within a frequency range of 25 MHz to 6,000 MHz, depending on the installed filters and operational requirements.
INTEGRATED BAND-SELECTIVE ANTENNAS
Each jamming module includes permanently integrated, band-selective ceramic antennas, ensuring predictable radiation patterns without external antenna dependencies.
STANDALONE AND NETWORKED OPERATION (LAN)
Standalone mode: system activates automatically on power-up | Network mode: remote configuration and control via LAN interface
PASSIVE COOLING – SILENT OPERATION
Fanless passive cooling design ensures silent operation and increased system reliability in continuous-use environments.
SUPPORTED NETWORKS
Designed to suppress common cellular and wireless technologies including GSM, UMTS, LTE, 5G bands, and Wi-Fi 2.4 / 5 GHz, subject to module configuration.
