Microwaves are widely used for point-to-point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams , which can be pointed directly at the receiving antenna.
What are the advantages and disadvantages of microwave communication?
- Advantage: Able to Transmit Large Quantities of Data.
- Advantage: Relatively Low Costs.
- Disadvantage: Solid Objects.
- Disadvantage: Subject to Electromagnetic and Other Interference.
Why microwave is so popular in different field of communication?
Microwave technology is used in radio for broadcasting and telecommunication of transmission because due to their small wavelength, highly directional waves smaller and therefore more practical than they would be at longer wavelengths (lower frequencies) before the introduction of Fiber optic transmission .
What are advantages of microwaves?
You can directly control cooking time , thus you have much better control over how much power you use. They also don't retain heat nor do they heat up everything in your kitchen. Microwave ovens use less energy than all conventional ovens or stoves since they directly heat up the water in the food.
What is microwave technology used for?
Microwaves have a range of applications, including communications, radar and, perhaps best known by most people, cooking. Electromagnetic radiation is transmitted in waves or particles at different wavelengths and frequencies. This broad range of wavelengths is known as the electromagnetic spectrum EM spectrum).
What is the biggest limitation of microwave communication?
You could put up repeaters between two towers if something is obstructing them. Also, signals have the ability to bounce off solid objects. Microwaves can even bounce off the moon. Another disadvantage of microwave signals is that electromagnetic interference, or EMI, can hinder or damage its execution .
What are the two types of microwave communication?
The two types of microwave transmission are terrestrial and satellite : Terrestrial microwave transmissions are sent between two microwave stations on the earth (earth station).
What are 5 uses of microwaves?
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial ...
Why the microwave is called as microwave what are its advantages?
A Microwave oven is designed to heat most foods in a quick and convenient way . The name Microwave is derived from the energy used to cook the food, microwaves, which pass through the cells and molecules of the food, the frequency of the waves causes the water molecules to vibrate, this movement generates heat.
Why microwave is used in radar?
Microwaves are used in radars because they can pass through any object . The frequency of the microwaves lies between infrared waves and radio waves and covers a high range of frequencies. ... The microwaves are electromagnetic waves with high wavelength and low frequencies. So, it is used in radar to detect the objects.
What are the negative effects of microwaves?
Microwave radiation can heat body tissue the same way it heats food. Exposure to high levels of microwaves can cause a painful burn . Two areas of the body, the eyes and the testes, are particularly vulnerable to RF heating because there is relatively little blood flow in them to carry away excess heat.
What are the uses and dangers of microwaves?
Microwaves are used for cooking food, communications and for satellite communications. Intense sources of microwaves can be dangerous through internal heating of body cells .
What are the positive effects of microwaves radiation?
This conclusion is consistent with the results of a previously reported study that showed that short-term exposure to microwave radiation can reduce reaction times and improve cognitive functions, attention and short-term memory capacity [28,29,30,31,32,33,34].
How are microwaves used in daily life?
Microwaves cause water and fat molecules to vibrate , which makes the substances hot. So we can use microwaves to cook many types of food. Mobile phones use microwaves, as they can be generated by a small antenna, which means that the phone doesn't need to be very big. Wifi also uses microwaves.
Do cell phones use microwaves?
Microwaves are electromagnetic waves with relatively long wavelengths and low frequencies. They are used for microwave ovens, cell phones , and radar. A cell phone encodes the sounds of the caller's voice in microwaves by changing the frequency of the waves. ... Radar stands for radio detection and ranging.
What is the need of microwave frequency?
Microwave frequencies are widely used for communication and interaction between objects (Body area network, Internet of things), leading to the development of various embedded sensors for the monitoring of vital signs (temperature, heartbeat, respiration, arterial pressure) or the follow-up of some kinds of pathologies ...
