My guest today is John Ulm. As an engineering fellow at CommScope, Ulm—like his company—has been a longtime player in cable technology covering the last three decades. He was in on the ground floor of broadband, helping to develop the first cable modems while at LANcity, and he was a primary author of the Data Over Cable Service Interface Specification (DOCSIS) 1.0 and 1.1 releases. His resume also includes stints as senior technical consultant with YAS Corp, an engineering fellowship at Motorola’s Broadband Group and later ARRIS. He was inducted into the Cable TV Pioneers as part of the inaugural DOCSIS class.
