What Wireless Networking Radio Frequency Yields Faster Speeds But Offers Shorter Range?

At some point as ham radio, have you asked yourself, what wireless networking Radio frequency yields faster speeds but offers a shorter range? In this article, we’ll try to answer that.

In order to know that, you have to stay here to see all the frequencies to select the best that suits your standard and needs.

But first, what is radio frequency? For those familiar, this is a familiar term, but for those new to learning, this is a term that refers to the smallest portion of the electromagnetic field, which occupies between 3 Hertz and 300 gigahertz.

In this way, hertz is the waveform used to measure the frequency. These electromagnetic waves can be transmitted through an antenna by applying alternating current.

Like all good ham radio, or at least, anyone who is starting in this field, you may have noted the fact that there are certain frequencies that can only be captured by using specific antennas.

This is because radio waves or radio frequencies are divided into different spectrum bands, so you have to know the difference between them in order to choose the best for you. The available frequencies are:

Super low frequency

This type of radio wave is located between 30 and 300 hertz. It has a wavelength range between 10,000 and 1,000 kilometers.

Due to its long range, it has a facility to cross the water in hundreds of meters of depth for which, governments of diverse countries, use these radio waves to establish communications with their submarine activities in the ocean.

The signals are processed by an algorithm, which converts them into audible sounds.

Ultra-low Frequency

This kind of radio wave refers to the frequency located between 300 and 3000 hertz (or 3 kilohertz), with a range of between 1000 and 100 kilometers.

Radio amateurs use this communication system with amplifiers that are connected to electrodes that are buried underground which increases the quality of audio.

Low Frequency

Also known as a “long wave”, is the one that covers between 30 and 300 kilohertz, therefore reaching a wavelength between 10 and 1 kilometers.

This radio wave is used for air and maritime navigation systems, besides as well as for radio broadcasting systems.

At this point, we can observe a change in its use, depending on the area in which it is located. In Europe, part of the low-frequency spectrum is used for AM broadcasting.

Whereas in the Western Hemisphere, it is used more frequently for the air control system, navigation, information system, and weather system.

The medium wave or Medium frequency

It is the band of the electromagnetic spectrum, which goes from 300 kilohertz to 3 megahertz (MHz), receiving a range of between 1 kilometer and 100 meters of the wavelength.

The primary use of this frequency was dictated by the International Telecommunications Union (ITU) and is the terrestrial broadcasting service.

This diffusion frequency is highly susceptible to sound, so distant storms can be easily heard, or even the natural noise of the planet can be heard.

That is why the most valuable moment of propagation of the medium wave is during the night since at this time the noise of the ionosphere decreases since the D layer disappears and it absorbs the medium frequencies during the day.

The ham radio in the world has a 160m band, which ranges from 1800 to 2000 kilohertz, depending on the country of course.

In that way, radio amateurs can interact on a regional, national, and even international level, with relative ease. As might be expected, this is possible at night, since, as it was mentioned before, during the days, this radio band presents too much noise and its range is diminished.

High Frequency

It is the waveband that covers between 3 and 30 megahertz, covering a wavelength located between 100 and 10 meters.

The short wave frequency is used by radio stations internationally and by radio amateurs, to transmit their programs or messages.

They are divided into two transmission bands. The daytime bands, which are between 14 and 30 megahertz, and as their name implies, spread better during the day and on summer days.

Night bands, on the other hand, are between 3 and 10 megahertz, causing their spread to be more favorable at night and on cold winter nights.

For radio amateurs, it is not necessary to have sophisticated equipment to be able to listen to international signals.

Very High Frequency

This is how the band of the electromagnetic spectrum that ranges from 30 to 300 megahertz is known, reaching a wavelength of between 10 to 1 meter in length.

This frequency is operated, not only in FM radio stations but also for communication between ships, maritime traffic control, and satellite communication.

The frequency used by ham radio is generally in the range of 144 megahertz to 148 megahertz, using the so-called “2-meter band”, which is the antenna used by ham radio to keep in touch with their acquaintances, with a range of 160 km.

Ultra-high Frequency

It is how the wave is known that is located between 300 megahertz and 3 gigahertz, with a wavelength of only 1 meter to 100 millimeters.

It is frequently used on television to broadcast national cable channels.

The ham radio, to carry out their communications, employ the system known as “Family Radio Service”, which is like a walkie-talkie (radio) system, using low-frequency transmitters, together with the two ultra-high frequency antenna bands. The 70 cm band, which operates between 430 and 440 megahertz, which must share frequencies with other low-frequency devices such as garage controls, home repeaters, and communication systems.

The 23 cm band, in the 1200 megahertz range, has great bandwidth and long-range, even managing to transmit television signals.

Why is important to know what are the differences between the wavelength and what wireless networking radio-frequency yields faster speeds but offers a shorter range?

This information is so important to consider when it comes to the t to select the proper radio frequency for you. You have to consider the range and the sharpness of the sound during the communication in order to express your messages without interruption.

As might be expected, each of the aforementioned radio frequencies has its differences, not only in range length and propagation speed but also in the quality of the message received

So, next time they ask you, which wireless network radio frequency produces faster speeds but offers a more limited range? You can count on a concise and satisfactory answer.

It must be remembered that certain radio frequencies are equally affected by external means such as the environment and the time of use.

Knowing these details will allow the radio amateur to get the most out of each of the radio frequencies used, therefore benefiting, to spread their messages more easily.

Common questions

Q-1. Can I use any frequency to communicate?

The selection of the proper wireless network will depend basically on the use that you have, for example, if you want to communicate during the night in a short distance (less than 100 meters) then we recommend the “high frequency” spectrum.

Q-2. Is it necessary to be a master in communication to use wavelength?

Not, keep in mind that most of the ham radio are rookies and you can use this as a hobby to meet new people.
