There was no "system" for either travel or communication in the middle ages. Most people never went beyond 5 miles from home in their life. It was hard to travel, dangerous, and took a long time. Communication was talking to each other. People couldn't read nor write and there was no mail system, so if someone had to tell another person something they had to do it in person. One reason we have testimony in the courts today is because in the middle ages people had to tell about the problem and what was wrong to the Lord of their manor/estate.

Sound waves can travel through liquids. These waves are mechanical waves that propagate by compressing and decompressing the molecules in the liquid. They are commonly used in underwater communication and navigation systems.
Radio waves are transmitted through antennas and travel through the air. They carry information in the form of electromagnetic signals. These waves are used in communication systems to transmit radio, television, and cell phone signals. They play a crucial role in enabling wireless communication over long distances.
Some of the benefits of European imperialism in Africa and Asia is that they created road systems for efficent travel, it introduced the world to new foods, spices and languages, and new species of animals and plants were discovered.
Space travel requires specialized equipment such as a spacecraft (rocket or shuttle), spacesuit for astronauts, life support systems, communication systems, navigation systems, and various scientific instruments for experimentation and data collection. Additionally, propulsion systems, solar panels or batteries, and thermal control systems are essential for sustaining life in the harsh conditions of space.
