Chief Scientist

Peter black

Previously an SVP of Technology and Fellow at Qualcomm, XCOM Labs Chief Scientist Peter Black has worked on wireless system designs spanning 2G/3G/4G/5G. He contributed to all aspects of the life cycle of new innovations, starting with the concept, system design, prototype, evangelization, standardization, and finally the commercial ASIC realizations. He was a modem system architect in 1995 for the first commercial CDMA modem chip – the foundational Qualcomm chip-set product. In 1998, Peter co-led an R&D project which led to the high-speed Mobile Internet starting with 1xEV-DO. Concepts such as shared downlink, adaptive HARQ, link adaption, carrier-state feedback, fairness scheduling, carrier aggregation and cellular broadcast were designed, prototyped, standardized, and commercialized over the next 10 years under his direct technical leadership. The 3GPP HSDPA standard was motivated by and based on this foundational EVDO work. He holds 200+ US patents and holds a B.E. in EE from University of Queensland and was awarded a University Medal. He was also awarded a Fulbright Traveling Scholarship and attended Stanford University graduating with an M.S. and Ph.D. in Electrical Engineering. 

Vice President of Wireless

Tamer kadous

Tamer Kadous is currently the VP of wireless in XCOM responsible for building and commercializing 5G technologies for KPI-demanding applications with emphasis on Xtended Reality (XR). In his current role, Tamer drives the wireless system across disciplines design, implementation, testing and deployment with tight integration of Augmented reality (AR) and Virtual reality (VR) applications. A primary design focus has been to understand multimedia pain points, to tailor the wireless transport for optimized End-to-End XR experience, and to meet the demanded but conflicting application’s KPIs. Under Tamer’s leadership, two systems have been built for licensed and unlicensed spectrum wireless technologies, deployed as pilots, and in the process of being commercialized.  

Before XCOM, Tamer worked in Qualcomm Research where his career focused on wireless communication systems design and implementation spanning areas of physical, MAC, upper layers, and RF Systems. He has held the role of Design Architect, Systems Lead and Project Lead for a variety of projects focusing on wireless innovations in WAN and connectivity areas including UMB (ultra-mobile broadband), WLAN, EV-DO, LTE, LTE-U, and MulteFire.  He served as the Chair of MulteFire Alliance Radio Working Group from 2016-2018 and was the technical lead for 5G shared spectrum and MulteFire (MF) Technologies in Qualcomm Research.

Tamer’s  primary focus has been the delivery of technology from design principals to performance evaluation, prototyping, standardization, and both base-station and terminal chipsets commercialization. A particular area of expertise for Tamer is on Wireless MIMO techniques

Vice President of XR

Serafin Diaz

XCOM Labs Vice President of XR Serafin Diaz is a brilliant engineer and multimedia whiz who previously acted as Vice President of Engineering at Qualcomm leading XR Research. His work in XR started in 2007 when he jump-started the first Augmented Reality project.  This project produced core real time Computer Vision technology which enabled not only XR but also became foundational to projects in robotics and autonomous driving. The inside-out 6DoF head tracking technology showcased in Qualcomm’s VR HMD reference design is an example of such technology. Serafin’s work influenced new generations of HW accelerators in Qualcomm’s SoCs.

He also led a variety of projects in areas concerning 2G CDMA data systems, test automation platforms for wireless devices, physical layer system integration and test for 1xEVDO as well as projects which laid down core technology for wireless VoIP and Video Telephony systems.
