Early Forms of Wireless Transmission
- Heinrich Hertz wrote about and experimented with early forms of wireless transmission.
- Marconi combined the ideas and experiments of other people to create a useful communications tool.
History of Electronic Communication
- Long-distance electronic communication dates back to the mid-19th century with the telegraph, which communicated messages through a series of long and short clicks.
- Cables across the Atlantic Ocean connected the United States and England, allowing for transatlantic communication.
