UNSPSC 52161563: Digital radio

In digital radios the analog audio signal is digitized into zeros and ones, compressed using formats such as mp2, and transmitted using a digital modulation scheme. The aim is to increase the number of radio programs in a given spectrum, to improve the audio quality, to eliminate fading problems in mobile environments, to allow additional services such as pause and rewind or song or show details, and to decrease the transmission power or the number of transmitters required to cover a region.

UNSPSC 52161563 Digital radio is a Commodity code covering radio equipment and accessories state and local governments procure for emergency response, law enforcement, and facility operations. Recent opportunities show the code encompasses both turnkey in-building radio frequency enhancement systems for emergency responder coverage and off-the-shelf Motorola radio units and accessories for sheriff offices and law enforcement operations. Issuing bodies span city procurement offices, county sheriff departments, and regional cooperative purchasing vehicles such as Sourcewell. City of Phoenix Finance Central Procurement, Santa Clara County Office of the Sheriff, and Sourcewell (a Minnesota local government unit facilitating multi-jurisdictional cooperative buying) appear as recent buyers.

Activity concentrates in Arizona, California, and the upper Midwest, with broader cooperative reach through Sourcewell's multi-state participating entities. Representative recent opportunities include the City of Phoenix IFB-26-0355 for in-building radio frequency coverage enhancement services using bi-directional amplifiers and distributed antenna systems across three airports, with responses due July 10, 2026 and a five-year term commencing August 25, 2026; Santa Clara County's RFQ for Motorola radios and accessories for the Office of the Sheriff, posted July 16, 2026 with quotations due July 24, 2026; and Sourcewell RFP #061626 for Law Enforcement Equipment on behalf of multiple participating jurisdictions in Washington and throughout the United States and Canada, with proposals due June 16, 2026. The Phoenix opportunity requires NICET certifications, Arizona professional engineer licensure, DBE-N compliance, FAA airspace protocols, and demonstrated three years of turnkey RF enhancement experience, suggesting higher technical barriers to entry for system design and installation work versus commodity radio purchasing.
