UNSPSC 32101540: Resolver

A rotation device that is used to detect the rotation angle from the servomechanism.

UNSPSC 32101540 Resolver, a Commodity code, encompasses emergency responder communication enhancement systems (ERCES), distributed antenna systems (DAS), bi-directional amplifiers (BDAs), and related radio frequency infrastructure that state and local governments deploy to improve public safety radio coverage in buildings and critical facilities. Recent solicitations show municipalities and special districts procuring turnkey design, installation, testing, and optimization of in-building RF systems to meet NFPA 1225 compliance standards; specialized radio equipment for law enforcement and transit fleets; ruggedized cellular routers for operational technology networks; and RF shielded chambers for engineering testing. Issuing bodies include city procurement offices (Phoenix), county sheriffs and water departments (Santa Clara County, Hillsborough County), school districts (Rockwood School District, Polk County Schools), state universities (University of Wisconsin-Madison, Texas A&M), and cooperative purchasing vehicles serving multiple jurisdictions (Sourcewell on behalf of Washington and Minnesota counties).

Activity is concentrated in Arizona, California, Florida, Missouri, Texas, and Wisconsin, with a cooperative procurement framework extending reach across the United States. Representative recent work includes the City of Phoenix Finance Central Procurement's in-building radio frequency coverage contract (IFB-26-0355, due July 10, 2026) for turnkey ERRCS design, installation, and five-year support with DBE-Neutral program compliance; Rockwood School District's digital bus radio procurement (RFP 26-14203, due April 29, 2026) for approximately 150 mobile radios, repeaters, and DMR Tier 2 compliant equipment with three-year service; Sourcewell's cooperative law enforcement equipment RFP (RFP #061626, due June 16, 2026) serving multiple Washington and Minnesota counties; the Polk County Schools ERCES inspection contract (ITB 033TD0426, due March 12, 2026) for semi-annual and annual testing to NFPA 1225 compliance; and the State of Florida's RFI for Cradlepoint E300 ruggedized cellular routers with NetCloud management (RFI OPN2131819F1, due March 26, 2026). Contractors typically must demonstrate three to five years of relevant experience, hold equipment-specific certifications (NICET IB-PSC for RF systems), employ state-licensed professional engineers, and meet federal compliance requirements including DBE participation plans, E-Verify enrollment, and FAA or aviation-specific security protocols where applicable.
