Telecommunications Expert Witness

Since 1996, I've been providing telecommunications expert witness services to the Telecommunications Industry.  With the rapid advancement of Data transmission other names have been coined, such as Communications, Information and Communications Technology (ICT), Structured Cabling Systems (SCS) and Information Transport Systems (ITS) as well as Information Technology (IT). I specialize in the cabling infrastructure that serves these various segments, whether inside buildings or outside on pole lines or underground.
