UNSPSC 43222611 Network channel or data service units, a Commodity code, encompasses the procurement of network switching and routing hardware, fiber optic cabling infrastructure, wireless access points, and associated professional services that state and local governments deploy to establish and upgrade internal communications and data transmission networks. State and local procurement under this code centers on replacing aging equipment at end of service life, expanding network capacity to support increasing device connectivity, and integrating modern network management platforms—work driven by the need for secure, stable communications between networked facilities and operational technology systems. Recent solicitations show a mix of stand-alone hardware purchases, integrated installation and configuration services, and E-Rate-funded infrastructure projects serving schools, county departments, airport authorities, and transit systems.

Issuing bodies pursuing this code span school districts of various sizes (Hillsborough County Public Schools in Florida with approximately $10.3 million in estimated network licensing procurement; Bibb County, Houston County, and Gordon County school systems in Georgia; Grosse Pointe Public Schools in Michigan; Tacoma School District in Washington), county government departments (Seminole County Public Works in Florida; Jackson County Board of Commissioners in Georgia; Broward County in Florida; Pinellas County School District in Florida; Sacramento County Department of Airports in California), cities and municipalities (Eugene, Oregon; Atlanta, Georgia; Philadelphia; Meriden, Connecticut; Long Beach, California; Palo Alto, California; Royal Oak, Michigan; Wake County, North Carolina), and special districts (Region 7 Purchasing Cooperative in Texas; Valencia College in Florida). Geographic activity is concentrated in the South and Southeast—Georgia school districts (Houston County, Bibb County, Gordon County, Fayette County, Savannah-Chatham County) post frequently—with secondary activity in Texas, California, Florida, and the Upper Midwest. Representative recent opportunities include the City of Eugene's cooperative procurement of Juniper Network Switches through NASPO (July 2026 vendor-comment deadline, $366,711.40 estimated value); the City of Atlanta Department of Aviation's IFB for network switch installation labor and expertise at Hartsfield-Jackson International Airport (August 3, 2026 bid deadline); Seminole County Public Works' IFB for network equipment to upgrade the Advanced Traffic Management System (July 22, 2026 deadline); Wake County IT Department's sealed-bid procurement for Cisco networking equipment requiring authorized Cisco Channel Partner status (July 10, 2026 deadline); Jackson County Board of Commissioners, Georgia's RFP for Cisco switching and routing equipment replacement with professional services, mandatory pre-proposal conference, and $1.5 million performance bond requirement (July 2, 2026 deadline); and Hillsborough County Public Schools' ITB for a 36-month Cisco Meraki Enterprise License Agreement covering approximately 26,000 network devices with estimated value of $10.3 million (February 22, 2026 deadline).
