2.

What is Radio Technology?
Wireless transmission of signals via
electromagnetic waves,
Foundation for modern
communication: radio, TV, mobile
networks, Wi-Fi, satellite links,
Key milestones driven by visionary
scientists across centuries.

3.

James Clerk Maxwell (1831–1879)
Contribution:
Developed the classical theory of electromagnetic
radiation (Maxwell’s Equations, 1860s)
Predicted existence of radio waves as part of the
electromagnetic spectrum
Impact:
Laid theoretical groundwork for all wireless
communication
Inspired later experimental work (e.g., Hertz,
Marconi)
Quote: “The electromagnetic field is that part of space
which contains and surrounds bodies in electric or
magnetic conditions.”

4.

Guglielmo Marconi (1874–1937)
Contribution:
Built the first practical radio transmission system
(1895)
Conducted first transatlantic radio signal (1901)
Impact:
Turned theory into real-world application
Shared 1909 Nobel Prize in Physics for wireless
telegraphy
Considered “father of radio communication”
Fun fact: His early experiments used a spark-gap
transmitter and Morse code.

5.

Andrea Goldsmith (1964)
Contribution:
Pioneer in wireless communication theory and adaptive
modulation
Developed key techniques for optimizing spectral efficiency
and network capacity
Impact:
Founding Dean of Engineering, Princeton University (2022–)
IEEE Fellow, National Academy of Engineering member
Key role in shaping 4G/5G standards and cognitive radio
Quote: “Wireless is not just about connectivity — it’s about
enabling intelligence at the edge.”

6.

Dr. Theodore (Ted) Rappaport (1958)
Contribution:
Founded NYU WIRELESS — pioneering research center
for mmWave communications
Pioneered channel modeling for 5G/6G (e.g., statistical
spatial channel models)
Impact:
Instrumental in enabling high-frequency (24+ GHz)
mobile networks
Co-founder of several wireless tech companies
IEEE Fellow & recipient of Marconi Prize (2020)
Key insight: “Millimeter waves will revolutionize wireless —
they’re abundant, clean, and fast.”
