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 …

The French word for microwave is E.g. le four à micro-ondes.

What is another word for microwave?

microwave (n.) type of electromagnetic wave, 1931, coined in English from micro- + wave (n.). First record of microwave oven is from 1961 (micro-oven also was used); microwave as short for this is attested from 1974; as a verb, from 1976.

A microwave is a small oven that cooks or heats food very quickly. Instead of the electric or gas heat that a regular oven uses, a microwave heats with electromagnetic radiation. These waves are themselves called microwaves because they’re short (and micro- means “small”), similar to radio waves.

• Long Distance Wireless Transmission. Most wireless transmission systems are based on microwave technology.
• Satellite Communication.
• Cell Phone Communication.
• Wi-Fi.
• Global Positioning System (GPS)
• Radar.
• Microwave Ovens.
• Bluetooth.

Microwaves are most commonly used in satellite communications, radar signals, phones, and navigational applications. Other applications where microwaves used are medical treatments, drying materials, and in households for the preparation of food.

Cell Phones Cell phone signals are carried through the air as microwaves. You can see how this works in the Figure below. A cell phone encodes the sounds of the caller’s voice in microwaves by changing the frequency of the waves. This is called frequency modulation.

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.

Radar systems transmit electromagnetic, or radio, waves. Most objects reflect radio waves, which can be detected by the radar system. The frequency of the radio waves used depends on the radar application.

Radars emit microwave energy, a longer wavelength, highlighted in yellow.

One of the most common uses of microwaves is to heat food quickly. Microwave ovens are possible because microwaves can be used to transmit thermal energy.

Microwaves are used for cooking food, communications and for satellite communications. Intense sources of microwaves can be dangerous through internal heating of body cells.

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.

Wi-Fi transmits data using microwaves, which are high-energy radio waves. Wi-Fi is more complicated than FM radio, but the basic underlying technology is the same.

Wireless devices often lose Internet connectivity whenever the microwave oven is running. This interference at 2.4 GHz can be caused by common 802.11b and 802.11g wireless devices, like routers, along with Bluetooth devices, baby monitors, cordless telephones, video senders, and microwave ovens.

The Electromagnetic Spectrum – Microwaves shown in gray. Microwaves range in frequencies from 100’s of MHz to 100’s of GHz. Presently the frequency bands used for 5G (between 3GHz to 28GHz) fall within this spectrum.

The Department of Defense has developed a non-lethal crowd control device called theActive Denial System (ADS). The ADS works by firing a high-powered beam of 95 GHz waves at a target—that is, millimeter wavelengths. This weapon operates on 95GHz waves and 5G will operate on the same frequencies.

Countries Where 5G Is Banned Numerous nations allege that the company’s products may contain security holes that China’s government can use for spying purposes. In addition, some countries allege that Huawei steals intellectual property from foreign technology companies.

6 Disadvantages of 5G

• Obstructions can impact connectivity.
• Initial costs for rollout are high.
• Limitations of rural access.
• Battery drain on devices.
• Upload speeds don’t match download speeds.
• Detracting from the aesthetics.

You do not need 5G connectivity right now. It’ll be several years at least before we see smartphones stop being released with less-than-5G connectivity. Though rare, we STILL see smartphones released today with 3G connectivity and no ability to connect to 4G. You are SAFE continuing to use your 4G smartphone.

5G Pros and Cons

• 5G PROS. There are numerous pros of 5G network including:
• 1) Faster Speeds.
• 2) Low Latency.
• 3) Increased Capacity.
• 4) More Bandwidth.
• 5) Powering Innovation.
• 5G CONS.
• 1) Limited Global Coverage.

5G access will enable individuals to have more smart devices that can reliably connect and interact with online services; at the same time, the technology can also create more detailed personal data sets for device manufacturers and service providers.

5G is faster and more secure than 4G. But new research shows it also has vulnerabilities that could put phone users at risk. (A similar vulnerability was found in the 4G protocol by University of Colorado Boulder researchers in June.) …

South Korea, China, and the United States are the countries that lead the world in building and deploying 5G technology.

6G is expected to launch commercially in 2030. 6G is being developed in response to the increasingly distributed radio access network (RAN) and the desire to take advantage of the terahertz (THz) spectrum to increase capacity, lower latency and improve spectrum sharing efficiency.

The new 10G circuits, operational in August, 2005, will terminate in Daejeon, S. Korea at the Daedeok Gigapop and will land in the US in Seattle at the PacificNorthwest Gigapop and in China at the “Hong Kong Open Exchange Point” managed by GLORIAD partners at the Chinese Academy of Sciences.

There are other countries also such as Japan, Hong Kong, and Sweden, which also provide fast Internet to their people. Some countries provide useful Internet, but they had not launched a 7G or 8G network.
