🦑 Frekuensi Sub Low Mid High

^{Dibawahini perbedaan, arti dan ciri-ciri smartphone kelas Low-End-Mid-End,} 5G carries information wirelessly through the electromagnetic spectrum, specifically the radio spectrum. Within the radio spectrum are varying levels of frequency bands, some of which are used for this next-gen technology. With 5G still in its early stages of implementation and not yet available in every country, you might be hearing about the 5G bandwidth spectrum, spectrum auctions, mmWave 5G, etc. Don’t worry if this is confusing. All you really need to know about 5G frequency bands is that different companies use different parts of the spectrum to transmit data. Using one part of the spectrum over another impacts both the speed of the connection and the distance it can cover. Lots more on this below. Defining the 5G Spectrum Radio wave frequencies range anywhere from 3 kilohertz kHz up to 300 gigahertz GHz. Every portion of the spectrum has a range of frequencies, called a band, that go by a specific name. Some examples of radio spectrum bands include extremely low frequency ELF, ultra low frequency ULF, low frequency LF, medium frequency MF, ultra high frequency UHF, and extremely high frequency EHF. One part of the radio spectrum has a high frequency range between 30 GHz and 300 GHz part of the EHF band, and is often called the millimeter band because its wavelengths range from 1-10 mm. Wavelengths in and around this band are therefore called millimeter waves mmWaves. mmWaves are a popular choice for 5G but also has application in areas like radio astronomy, telecommunications, and radar guns. Another part of the radio spectrum that’s being used for 5G, is UHF, which is lower on the spectrum than EHF. The UHF band has a frequency range of 300 MHz to 3 GHz, and is used for everything from TV broadcasting and GPS to Wi-Fi, cordless phones, and Bluetooth. Frequencies of 1 GHz and above are also called microwave, and frequencies ranging from 1–6 GHz are often said to be part of the "sub-6 GHz" spectrum. Frequency Determines 5G Speed & Power All radio waves travel at the speed of light, but not all waves react with the environment in the same way or behave the same as other waves. It's the wavelength of a particular frequency used by a 5G tower that directly impacts the speed and distance of its transmissions. Higher Frequency Faster speeds. Shorter distances. Lower Frequency Slower speeds. Longer distances. Wavelength is inversely proportional to frequency high frequencies have shorter wavelengths. For example, 30 Hz low frequency has a wavelength of 10,000 km over 6,000 miles while 300 GHz high frequency is just 1 mm. When a wavelength is really short such as the frequencies at the higher end of the spectrum, the waveform is so tiny that it can become easily distorted. This is why really high frequencies can't travel as far as lower ones. Speed is another factor. Bandwidth is measured by the difference between the highest and lowest frequency of the signal. When you move up on the radio spectrum to reach higher bands, the range of frequencies is higher, and therefore throughput increases you get faster download speeds. Why the 5G Spectrum Matters Since the frequency used by a 5G cell dictates the speed and distance, it's important for a service provider like Verizon or AT&T to use a part of the spectrum that includes frequencies that benefit the job at hand. For example, millimeter waves, which are in the high-band spectrum, have the advantage of being able to carry lots of data. However, radio waves in higher bands are also absorbed more easily by gases in the air, trees, and nearby buildings. mmWaves are therefore useful in densely packed networks, but not so helpful for carrying data long distances due to the attenuation. For these reasons, there isn't really a black and white "5G spectrum"—different parts of the spectrum can be used. A 5G provider wants to maximize distance, minimize problems, and get as much throughput as possible. One way to get around the limitations of millimeter waves is to diversify and use lower bands. A frequency of 600 MHz, for example, has lower bandwidth, but because it’s not affected as easily by things like moisture in the air, it doesn't lose power as quickly and is able to reach 5G phones and other 5G devices further away, as well as better penetrate walls to provide indoor reception. The 5 Best Smartphones of 2023 For comparison, low-frequency LF transmissions in the range of 30 kHz to 300 kHz are great for long-distance communications because they experience low attenuation, and therefore don't need to be amplified as often as higher frequencies. They're used for things like AM radio broadcasting. A service provider might use higher 5G frequencies in areas that demand more data, like in a popular city where there are lots of devices in use. However, low-band frequencies are useful for providing 5G access to more devices from a single tower and to areas that don't have direct line-of-sight to a 5G cell, such as rural communities. Here are some other 5G frequency ranges called multi-layer spectrum C-band 2–6 GHz for coverage and Data Layer Over 6 GHz 24–29 GHz and 37–43 GHz for high bandwidth Area Below 2 GHz like 700 MHz for indoor and broader coverage areas. 5G Spectrum Usage by Carrier Not all service providers use the same frequency band for 5G. Like we mentioned above, there are advantages and disadvantages to using any part of the 5G spectrum. T-Mobile Uses use low-band spectrum 600 MHz as well as GHz spectrum. Sprint has been merged with T-Mobile and claimed to have more spectrum than any other carrier in the US, with three spectrum bands 800 MHz, GHz and GHz. Verizon Their 5G Ultra Wideband network uses millimeter waves, specifically 28 GHz and 39 GHz. AT&T Uses millimeter wave spectrum for dense areas and mid and low-spectrum for rural and suburban locations. 5G spectrum has to be sold or licensed to operators, like through auctions, in order for any company to use a specific band. The International Telecommunication Union ITU regulates the use of the radio spectrum around the world, and domestic use is controlled by different regulatory bodies, such as the FCC in the US.

Beginner's GuideUnderstanding different sound signatures for your Headphones and EarphonesIf you're someone who's browsing our incredible collection of headphones and in-ear monitors on our website, one of the things that you'll see us talking a lot about to describe each of these headphones is its sound signature. The sound signature for headphones is telling you a little about how these headphones are supposed to present your music to you when you put them on and how they're tuned to be able to play all the different parts of the music together. A sound signature is perhaps the best way to describe what you should expect to listen to when you put these headphones on. In this video, I'm going to help you try and understand these different sound signatures that we have and hopefully pick the right one for you. Intro Hi guys this is Raghav here from headphone Zone. If you're someone who'sbrowsing our incredible collection of headphones and in-ear monitors on ourwebsite one of the things that you'll see us talking a lot about to describe eachof these headphones is its sound signature. The sound signature forheadphone is really telling you a little bit about how these headphones aresupposed to present your music to you when you put them on and how they'retuned to be able to play all the different parts of the music together. A soundsignature is perhaps the best way to describe what you should expect to listento when you put these headphones on. In this video I'm going to help you tryand understand these different sound signatures that we have and hopefullypick the right one for you. Understanding different sound signatures First things first, I'm sure when we all started off in our childhood we must haveplayed around with the equaliser on an old radio system or on a car audiosystem. You have the bass and the treble and you would have turned theseknobs up and down to listen to what difference they made to the way that yourmusic is playing. Perhaps the easiest thing to understand is the bass, you turnup the bass and all the low frequencies, the energy and the thump getsexaggerated, gets turned up and the bass dial is the easiest way to turn up aparty. You know that the kick drum, the bass guitar, all of these are instrumentsthat are featured in the low frequencies or the bass, it's really what makesmusic sound fun and energetic. When we're listening to music on a laptopspeaker or a mobile phone speaker you'll find that there's virtually no bassbecause these are really really tiny speakers and they're punching out a largevolume of air but for the bass to be there it's got to be a much larger speaker tobe able to give you that low frequency and therefore for a lot of us good sound is simply equivalent to a lot of bass and if you are someone who's looking tohave a party and you're looking for that kind of a sound signature when you puta headphone on there are a whole bunch of brands and headphones thatmarket themselves as an extra bass sound signature. It's really coming from aschool of thought where people think that extra bass is good sound but thatcouldn't be further from the truth. When you're listening to good soundingheadphones, a lot of bass can basically muddle out and overpower the rest ofthe frequencies. You'll find that music will no longer sound believable andauthentic or very well balanced when the bass is overpowering everything with time you'll find that a more balanced sound signature which is the kindof sound signature that all high end headphones and speakers tend to have. Itis where all the frequencies not just the bass is presented equally. You'll findthat the mid-range which is typically where your vocals instruments like thepiano and guitars, trumpets and violins are there and the highs which is thetreble frequencies where you have a lot of sharp, shrill instruments,percussions, cymbals that basically add the excitement, the drama on top ofthe music and the bass are all presented equally importantly. The instrumentsare clearly distinct and a balanced sound signature everything sounds muchmore believable much more as the artist intended. When you put theseheadphones on and hit play sometimes the sharp frequencies the higherfrequencies that we call as treble can also add a lot of excitement and drama tothe music. You would have experienced this when you take the treble knob onyour car audio system and turn it up to max. These are the sharp, shrillfrequencies that can sound really really exciting and fun but over long periodsof time it also sometimes causes fatigue. It can sound a little too shrill, a littletoo sharp. In the right amount it can sound airy, it can sound shining, it cansound exciting, so there are a whole bunch of headphones whose soundsignature can be sometimes described as bright. If they pay a lot of emphasison the treble frequencies and some people like that a lot and a lot of people willfind that very fatiguing or very tiring. It can sound like pins in your ears if you'relistening to music for long hours at a time. So what some people like to do is tojust turn down that treble just a little bit and that kind of smoothens out thetreble and headphones that tend to do that can be described as warm andsmooth. That's the kind of sound signature that you want to go for if you want alittle bit of bass but you also want that treble toned down a little bit so that itdoesn't kind of make it harsh and tiring and fatiguing to listen to. Lastly I wantto talk to you about what we call a flat sound signature. This is not verydifferent from a balanced sound signature but if you're someone who's using aheadphone in the studio for recording music or for a professional purposewhere you're editing the soundtrack of a movie or a video then you want aheadphone that's really a great tool for you to be able to make changes to yourrecording while mixing and mastering. The headphone is really your referenceand for this you want the headphone to be able to play all the frequencieswithout exaggerating or diminishing any part of the sound spectrum. Theseheadphones we typically call as flat, it's because they represent all thefrequencies perfectly neutrally. If you're someone who's looking for just the right amount of balance between the bass and the treble which you also wantto turn it up a little bit to add a little bit more punch to the low end and a littlebit more excitement to the high end, we can describe this kind of a soundsignature as a v-shaped sound signature. It's where you have just that littlemore emphasis on the lows and the highs in virtually equal proportion and themid-range can sometimes be a little recessed but this is the most exciting andfun kind of sounding sound signature that a lot of audiophile really crave and gofor. On the other hand a flat sound signature is not very different from abalanced sound signature but is really the kind of sound signature that doesn'temphasise or exaggerate any frequency throughout the entire spectrum andthis is really really important for people who are using headphones in the studiofor a professional application like editing of sound or recording or for recordingmusic and you'll find that the headphones are a tool. It's a reference for you toknow what your music should sound like and a flat sound signature is exactlythe kind of sound signature you want to go for for use for that application. Outro so with this video I think now you should be able to understand all the differentsound signatures that we talk about on our website you have an extra basssound signature you have a warm and smooth sound signature you have abalanced sound signature you have a bright sound signature and a v-shapedsound signature while also looking at a flat sound signature so that's a coupleof different and hopefully you've understood the right one for you. .
