UNSPSC 32101539: Frequency selector

A device that operates the signal apparatus by using the signal current of several different frequencies, such as responding only by the resonant on specific frequency, automatically identifying the interval of wireless frequency signals, and others.

UNSPSC 32101539 Frequency selector is a Commodity code under which state and local governments procure in-building radio frequency enhancement systems, emergency responder communications infrastructure, dispatch radios, and related RF transmission and reception equipment to support public safety, transportation, and operational technology networks. Recent solicitations show heavy emphasis on distributed antenna systems (DAS), bi-directional amplifiers (BDAs), and Emergency Responder Radio Coverage Systems (ERRCS) designed to meet NFPA 1225 standards for buildings, vehicles, and distributed facilities. The issuing-body mix spans city governments (Phoenix Finance Central Procurement), counties (Santa Clara, Polk County, Hillsborough County, Franklin County, Grant County, Grays Harbor County, Chelan County, Yakima County), school districts (Rockwood R-VI in Missouri, School Board of Polk County), state universities (Texas A&M System, University of Wisconsin-Madison), and multi-jurisdictional cooperative purchasing vehicles (Sourcewell). Cities and school districts represent the most visible recent solicitors, followed by special-purpose districts managing water and transportation infrastructure.

Geographic activity concentrates in Arizona (City of Phoenix issued two IFBs for in-building RF coverage revision and initial coverage in 2026), Florida (School Board of Polk County, Hillsborough County Water Resources, State of Florida RFI on ruggedized cellular routers), California (County of Santa Clara RFQ for Motorola radios and accessories), Texas (Texas A&M System RFP for IP-based operational communications), Missouri (Rockwood School District RFP for bus radios), Minnesota and Washington (Sourcewell cooperative RFP for law enforcement equipment spanning Franklin, Grant, Grays Harbor, Chelan, and Yakima counties), and Wisconsin (University of Wisconsin-Madison RFBs for RF shielded chambers). Representative recent opportunities include the City of Phoenix IFB 26-0355 for in-building radio frequency coverage revision (sealed offers due July 10, 2026, five-year contract with DBE-N requirements and FAA compliance obligations for three airports), Rockwood School District RFP 26-14203 for bus radios serving approximately 19,000 students (RFP due April 29, 2026, requiring approximately 150 mobile radios with DMR Tier 2 compliance and 90-percent district-wide coverage), and the Sourcewell RFP #061626 for law enforcement equipment (RFP due June 16, 2026, establishing contracting solutions available to thousands of governmental agencies across the United States and Canada through cooperative purchasing).
