CONX Corp. (OTCPK: CNXX) operates as a diversified holding company focused on communications, connectivity, and spectrum-sharing technologies; it provides scalable cloud-based Spectrum Access System (SAS) solutions for Citizens Broadband Radio Service (CBRS) and TV White Space (TVWS) dynamic spectrum sharing, enabling operators across private networks, rural broadband, and enterprise sectors to access shared spectrum efficiently. Through its majority-owned subsidiary RED Technologies SAS, founded in 2012 and now headquartered alongside CONX in Littleton, Colorado, the company offers SAS administration services, including GAA coexistence features, Network Planner tools, and AI-based CBRS analytics; these solutions support FCC-compliant spectrum allocation for operators of all sizes, with deployments in the United States through partnerships such as Amdocs and contributions to 6GHz standardization via Automatic Frequency Coordination (AFC). CONX, incorporated in 2020, targets emerging companies in technology, media, telecommunications, and wireless communications, primarily in North America and Europe, serving telecom operators, private network providers, and rural broadband initiatives. In December 2024, CONX acquired approximately 68% of RED Technologies SAS for up to EUR 18.6 million through its wholly-owned subsidiary RED Tech US, LLC, with remaining shares contingent on milestones, positioning the company as a challenger to the CBRS SAS duopoly and accelerating development of advanced features; this followed Nasdaq delisting in July 2024 and included a PIPE investment from EchoStar for about $400 million to bolster liquidity and future expansions.
