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 (Commodity) encompasses radio frequency equipment and in-building RF coverage systems that state and local governments procure for emergency responder communications, law enforcement operations, and fleet management. Recent solicitations show the code capturing turnkey RF enhancement services—bi-directional amplifiers, distributed antenna systems, and related equipment—alongside standalone radio and accessories procurement for law enforcement agencies. The work spans design, installation, testing, optimization, inspection, and repair services across municipal buildings, transit systems, and county sheriff offices. Issuing bodies include school districts, city finance and procurement departments, county sheriff's offices, and university systems. Santa Clara County's Office of the Sheriff has posted multiple RFQs for Motorola radios and accessories, indicating repeat buying activity under this code.

Activity appears across Florida, California, Arizona, Texas, and through cooperative purchasing vehicles.
