Beijing, China – March 18, 2024 – As unauthorized drone activity continues to challenge airspace security at power plants, oil refineries, and other critical sites, BNT has reached a major milestone. The company’s flagship counter-UAV component, the BNT-WB200 wideband anti-drone module, has officially passed certification by China’s National Radio Monitoring Center Testing Center (SRMC). The approval validates both the technical sophistication and operational reliability of the module, giving security integrators a fully compliant building block for next-generation low-altitude defense.
A Purpose-Built Module for the “Rogue Drone” Problem
The rapid spread of consumer and DIY drones has created an asymmetric threat. A small quadcopter carrying a camera or a dangerous payload can breach perimeter fences in seconds, and traditional single-band jammers often fail against frequency-agile platforms. BNT engineered the BNT-WB200 to close those gaps. The module delivers a flat 20 W of RF output across an extraordinarily wide single-chain bandwidth—10 MHz to 6 GHz—allowing it to simultaneously disrupt the most common drone control and navigation frequencies.
During certification testing, the BNT-WB200 demonstrated consistent power delivery with ±1.5 dB gain flatness across the entire operational band. Harmonic suppression measured below -25 dBc, a critical feature that minimizes interference with friendly communication systems and ensures the module can be deployed in electromagnetically sensitive environments.
The Specs That Passed the Lab and the Field
SRMC certification looked beyond raw power figures. The evaluation covered frequency accuracy, spurious emissions, thermal stability, and response latency. Here’s a snapshot of the performance metrics that earned the BNT-WB200 its approval.
| Parameter | Certified Value |
|---|---|
| Frequency Range | 10 MHz – 6 GHz |
| RF Output Power | 150 W (±1.5 dB flatness) |
| Simultaneous Bands | 2.4 GHz, 5.8 GHz, GPS L1 (1.57 GHz) |
| Response Time (trigger to full RF) | < 0.3 seconds |
| Harmonic Suppression | < -25 dBc |
| Remote Management | Ethernet (RESTful API), UART |
| Duty Cycle | 100% continuous (with active cooling) |
The sub-0.3-second response time is particularly crucial. When integrated with a radar or RF-detection sensor, the module can switch from idle to full jamming output almost instantly, catching a fast-moving drone before it enters a protected area. The Ethernet-based remote management interface lets security operators adjust frequency bands, output power, and duty cycles from a control room or a remote operations center—a feature that resonated strongly with utility and energy companies managing geographically dispersed sites.
Designed for the Infrastructure That Can’t Afford Downtime
What sets the BNT-WB200 apart from generic jamming modules is its system-integration flexibility. The module can work as a standalone unit paired with external detection equipment, or it can be embedded directly into existing counter-UAV platforms. This dual-mode capability means it fits into new installations and retrofits alike, protecting sectors where security continuity is non-negotiable.
During the certification review, BNT also provided field-test data from deployments in power substations and petrochemical facilities. The module consistently demonstrated its ability to force rogue drones into failsafe modes—return-to-home, hover, or immediate landing—without interfering with on-site operational communications. At one trial, the BNT-WB200 integrated with a third-party RF sensor network successfully neutralized a drone swarm simulation at a 1.2-kilometer standoff distance.
BNT’s Director, Ms. Yang Ying, commented: “This certification is more than a document. It tells our customers that the BNT-WB200 isn’t just powerful on a spec sheet; it has been rigorously validated by the national authority. For infrastructure operators who must comply with strict anti-terrorism technical standards, that assurance is everything.”
A Platform Built for Evolving Threats
The drone threat landscape keeps shifting—from off-the-shelf camera drones to custom FPV models using encrypted, frequency-hopping protocols. The BNT-WB200’s wideband architecture provides inherent agility. Its built-in frequency synthesizer supports multiple jamming modes: swept frequency, broadband noise, and protocol-aware disruption. Security teams can configure the module to allocate noise to 2.4 GHz while sweeping 5.8 GHz, or to emit a complex GPS spoof signal on L1, all from the same hardware.
Thermal design was another focus area scrutinized during certification. The module uses an integrated copper heat spreader and supports active fan cooling, enabling 100% duty cycle continuous transmission. For 24/7 fixed-site protection—think perimeter security at a sprawling refinery or an unmanned substation—this reliability is non-negotiable.
From National Certification to Global Ambitions
With the SRMC certification in hand, BNT is now ramping up production to meet demand from domestic critical infrastructure operators. The company also plans to pursue CE and FCC certifications, signaling its intent to bring the BNT-WB200 to international markets where similar counter-drone mandates are emerging.
“Technology and integrity are the twin engines of our growth,” Yang added. “We built the BNT-WB200 because the market needed a module that was genuinely wideband, genuinely fast, and genuinely compliant. The SRMC certification confirms we delivered that. Now we’re going to carry that same spirit into every market we serve.”
Looking Ahead
The BNT-WB200 is already being integrated into next-generation counter-UAV systems at multiple pilot sites across China. BNT expects the module to become a standard reference design for critical infrastructure protection, border surveillance, and major public event security. As the company continues to invest in R&D and expand its global footprint, the SRMC-certified BNT-WB200 serves as a clear statement: BNT is not just participating in the counter-drone conversation—it’s setting the technical baseline others will be measured against.
