UNSPSC 32101534: Wave trap

A device that attenuates the interfering wave by adding the rejection circuit consisted of high frequency coil and condenser between the receiving antenna and receiver to heighten the selectivity of the receiver.

UNSPSC 32101534 Wave trap is a Commodity code representing specialized electromagnetic containment and signal-isolation equipment that state and local governments procure primarily for emergency responder communications infrastructure, operational technology (OT) systems connectivity, and radiofrequency laboratory and testing applications. Recent solicitations show wave traps embedded within larger in-building radio frequency coverage system procurements—turnkey Emergency Responder Radio Coverage Systems (ERRCS) using bi-directional amplifiers (BDAs) and distributed antenna systems (DAS)—rather than as standalone commodity purchases. The City of Phoenix has been the most active recent buyer, issuing two major IFBs for five-year turnkey in-building RF enhancement contracts across its municipal and airport facilities, both requiring NFPA 1225 and UL 2524 compliance and NICET-certified personnel. Beyond traditional emergency communications, the code sees activity in ruggerized cellular router and critical OT system deployments (Florida county RFI for Cradlepoint E300 cellular routers with secure VPN for SCADA/IoT assets) and specialized RF testing infrastructure (University of Wisconsin-Madison RFBs for RF shielded chambers for engineering applications). The issuing-body mix spans city procurement offices (Phoenix Finance Central Procurement), county water and environmental departments (Hillsborough County Water Resources), state institutions (University of Wisconsin-Madison), and cooperative purchasing vehicles (Sourcewell representing multiple county jurisdictions in Washington state).

Activity concentrates in Arizona (Phoenix), Florida (Polk County schools, Hillsborough County Water Resources, and a county RFI), Wisconsin (University of Wisconsin-Madison), and across multiple states through Sourcewell's cooperative procurement for law enforcement equipment. Representative recent opportunities include the City of Phoenix IFB 260355 for in-building RF coverage revision (due July 10, 2026, for a five-year turnkey ERRCS/DAS/BDA contract commencing August 25, 2026); the City of Phoenix IFB 260148 for in-building RF coverage (closed April 30, 2026, for a July 1, 2026 start); the Polk County School Board ITB 033TD0426 for ERCES inspections and compliance testing (due March 12, 2026); and the Sourcewell RFP 061626 for law enforcement equipment (due June 16, 2026, establishing a multi-state cooperative contract vehicle). The code shows steady activity tied to public safety radio infrastructure modernization, NFPA 1225 compliance mandates, and secure OT connectivity for critical systems, with contracts typically spanning three to five years and requiring specialized NICET or professional engineering certifications for installation and testing personnel.
