Summary
Author Biography
Daniel Fox currently works for Anritsu - the world leader in measurement systems for ISDN optical communications — as Director of Technology. He has overall responsibility for system architecture for the company's wireless test and measurement platforms.
Daniel has been at Anritsu since 1999 and, prior to his appointment as Director of Technology, managed the business unit responsible for protocol test software solutions for UMTS. He served as an official in the 3GPP standards programme, first as the Chair of the signaling sub-working group that developed the protocol conformance test specifications, and later as Convener of that group and Vice-Chair of the terminals working group. Before joining Anritsu Daniel worked for Motorola Semiconductors for almost 10 years.
He has a degree in Applied Physics and Biology from the University of Wales, University College Swansea.
