Doug is a Senior Director of Research and Innovation responsible for Technology Evolution and Prototyping. He manages a team of innovators, systems designers and implementation engineers who identify, design and prototype concepts for next generation wireless systems (5G & 6G). The results of Doug and his team’s work can be found at Mobile World Congress, Brooklyn 5G Summit, and numerous publications in the InterDigital Vault. Doug Castor has more than 25 years of experience in wireless system innovation, analysis, design and implementation. Since joining InterDigital in 2000, he has been developing and delivering next generation technology for the mobile wireless industry. His work has been incorporated into 3G (WCDMA and HSPA), 4G (LTE Advanced), and his recent research is targeted for 5G (NR) and 6G systems. Doug has directed departments as large as 35 employees within InterDigital’s Research and Innovation organization where he has both administrative and technical planning responsibilities. He is currently directing a development team aiming to bring gigabit data rates, extreme low latency and ultra low power to next generation mobile devices. Key technologies of interest to Doug include millimeter wave (mmWave) and terahertz frequencies applied to small cell access and backhaul, and multi-access edge computing. Doug’s work has resulted in demonstrating InterDigital’s EdgeHaul platform - the world’s first WiGig-based mmWave mesh backhaul system that can wirelessly transport multi-gigabit-per-second data to small cells. He is the inventor of 14 granted patents with many additional patent applications pending. Doug also has prior experience working for Lockheed Martin in satellite communications systems where he developed wireless performance analysis software and validated system designs prior to launch.
