2-day instructor-led training

This two-day seminar provides a solid grounding in principles of basic wireless system design and RF engineering. After a brief appreciation of the development of cellular, it surveys the main analog and digital standards in current use, noting specific features and capacity implications. Propagation, wireless antenna systems, and traffic engineering principles are thoroughly introduced. Finally, wireless system design, growth, and performance considerations are explored each student receiving example files on disk.

Basic technical mathematics; exposure to general electronics.

Engineers, technicians, and technical managers with technical backgrounds but limited wireless experience.
