Serial ports
A telemeter remotely measures things, such as quantity and/or distance. It can then transmit the data long distances over radio frequencies.
The bundles of neurons that transmit impulses over long distances are called nerves. Nerves are composed of axons, which are the long fibers that carry electrical impulses from one part of the body to another.
Microwaves are typically used to communicate with satellites in space due to their ability to penetrate Earth's atmosphere and transmit data over long distances reliably.
Wireless communication technologies, such as Wi-Fi, Bluetooth, and cellular networks, allow for communication over long distances without the need for physical cables. These technologies use electromagnetic waves to transmit data through the air, enabling devices to connect and communicate with each other seamlessly.
morse code
It used wires to transmit Morse Code over short distances
Laser light is used to transmit data through optical fibers by converting electrical signals into light pulses. The light pulses travel through the optical fibers, which are designed to minimize signal loss and maintain the integrity of the data over long distances. At the receiving end, the light pulses are converted back into electrical signals for interpretation. This method enables high-speed, reliable communication over long distances without significant signal degradation.
It made it possible to amplify weak radio signals and transmit them over long distances
Microwave signals travel at the speed of light in air, which is approximately 299,792,458 meters per second. This high speed allows microwave signals to transmit data rapidly over long distances.
radio waves
The neuron has a long, thin tube called the axon which sends an electric nerve impulse very quickly, akin to an electrical cord.
To say that you cannot transmit electricity wirelessly is completely wrong. You can actually transmit electricity through the air by magnetic field through a mechanism called "inductive coupling" or "resonance coupling" over short distances. Over long distances, you can convert it to microwaves. However, it has not become popular due to various reasons.
