Como é possível configurar um link sem fio sem saber muito sobre os vários parâmetros avançados que um deve permitir, muitos usuários enfrentam problemas quando os links ficam submetidos a interferência. Uma das perguntas que recebo é muito, o que obviamente é uma conseqüência direta do pouco conhecimento que a maioria dos usuários do espectro de freqüência de 5GHz tem, qual largura de canal é melhor usar? Tendo em mente que ser um bom engenheiro de rede não faz necessariamente um bom engenheiro sem fio, tentarei explicar o uso das larguras de canal de 20MHz ,40MHz e 80MHz . Curso Completo Mikrotik Largura do canal 20MHz A largura do canal de 20MHz nos rádios Mikrotik 5GHz estabelece ponto a ponto ou aponta para conexões multiponto em um espectro mais estreito. O que isto significa é que, na largura do canal de 20MHz, você terá um sinal muito melhor, menos interferência, mas com menor throughput. Devido a isso, a velocidade do link será mais lenta em comparação com um link de 40MHz, sendo todas as coisas o espectro é estreito, as chances de o rádio da estação pegar outros SSIDs na mesma freqüência serão menores. O sinal do AP é capaz de ir longe e é captado com melhor qualidade de conexão do cliente CCQ pelo s rádio s da estação. No entanto, a velocidade é reduzida por causa do espectro estreito. A largura do canal de 20MHz é recomendada para conexões de longa distância . Largura do canal de 40MHz A largura do canal turbo de 40MHz ou 40MHz, transmite em amplo espectro de frequência, dando espaço para velocidade, mas com uma grande possibilidade de flutuações de sinal causadas por interferência. Com o espectro de 40MHz cobrindo um espectro mais amplo, o sinal transmitido pelo AP cobre menos distâncias, enquanto a estação, também em 40MHz, pega os SSIDs na mesma freqüência que o AP ao qual está conectado. Isso resulta em interferência de sinal. A largura do canal de 40MHz é adequada para links implantados em distâncias curtas com alta demanda de largura de conclusão, use a largura do canal de 40MHz para links que cubram a curta distância com alta demanda de largura de banda, enquanto a largura dos canais de 20MHz deve ser usada para links sem fio de maior distância. Curso Consultor Projetista de Redes Ópticas Observe que a largura do canal configurada no AP também deve ser configurada na estação para que o link seja estabelecido. Largura do canal de 80MHz A largura do canal de 80MHz nos rádios Mikrotik , está disponível apartir do protocolo e oferece um canal ainda mais amplo e, como tal, maior largura de banda. No entanto, isso torna ainda mais suscetível a interferência co-canal . Desta forma, os canais de 80 MHz são melhor utilizados com base no melhor esforço, mas somente quando o alcance total do canal é claro. Se você tiver alguma dúvida sobre qual Largura de Banda do Canal você deve usar em sua rede, por favor, comente abaixo. Improving and managing Wi-Fi performance is important to everyone, from home users to large enterprises. Channel width plays a big role in Wi-Fi performance. Selecting the right Wi-Fi channel widths can have a huge impact. Getting it right isn’t always straightforward, though. With multiple standards and a variety of tradeoffs, it can be hard to keep up with best wireless environment is different and you need to tailor your equipment to the conditions. With GHz, increasing your channel width often isn’t worth it, and you should stick with 20 MHz. Conversely, with 5 GHz, increasing channel width can improve performance, but there are tradeoffs. With 5 GHz, if you don’t have to worry about interference and all your client devices support it, go with the highest width course, there are plenty of “gotchas” and the rules of thumb above won’t always be best for you. Like most things in tech, the right answer to this question depends on context. Let’s explore the “why” behind these generalisations to help you gain a better understanding of the Wi-Fi BandsUnderstanding Wi-Fi bands is vital to understanding when to use 20 MHz versus 40 MHz versus 80 MHz channel widths. It’s also an important prerequisite to understanding WiFi channels and channel two main Wi-Fi bands are GHz and 5 GHz. These Wi-Fi bands are then split into channels for wireless devices to communicate GHz Wi-Fi BandThe GHz band covers a 100 MHz range of 2400 MHz to 2500 MHz equivalent to GHz to GHz. The GHz band is split into 14 discrete channels that are 20 MHz each more on other channel sizes in a bit.Note in the image above that there are 14 channels in the GHz band. Note that channels 1, 6, 11, and 14 do not you do a quick calculation, you’ll quickly see that 14 bands of 20 MHz equals 180 Mhz. This is greater than the 100 MHz size of the GHz band, which means that channels is important to understand because overlapping Wi-Fi channels can interfere with one another. With GHz Wi-Fi, there are four non-overlapping 20 MHz channels 1, 6, 11, and 14. Note that due to varying regulations, not all channels are available for use in all locations. For example, only 13 channels are available in Australia so we only have three non-overlapping GHz Wi-Fi BandThe 5 GHz Wi-Fi band up to Wi-Fi 6 covers a 150 MHz range from GHz to GHz. Wi-Fi 6E extends that band. However, an additional range of Unlicensed National Information Infrastructure UNII bands widens that range to 750 MHz. Using 20 MHz, there are 24 non-overlapping channels available within the 5 GHz band. Note that this is a generalisation and available channels vary depending on location and channel GHz vs 5 GHz Popularity, interference, throughput, and GHz is more popular than 5 GHz since many of the cheaper routers or industrial routers only support GHz, but both are widely used. GHz is cheaper to implement than its 5 GHz counterpart, so manufacturers leverage it to save costs. GHz has also been widely used for a longer period of time, so more GHz devices have been popularity does have a downside, though. The prevalence of GHz devices and limited number of non-overlapping channels with GHz can exacerbate network congestion consumer devices, such as cordless phones and microwaves, use GHz frequency bands. As a result, GHz bands are more likely to experience interference. The relative abundance of non-overlapping channels on 5 GHz Wi-Fi makes it less susceptible to GHz vs 5 GHz Which to Use?In most cases you should use GHz to optimize for distance and 5 GHz to optimize for speed. However, there is a tradeoff between increased performance and range of GHz is faster. 5 GHz Wi-Fi offers faster uploads and downloads than GHz. Additionally, 5 GHz benefits from more non-overlapping channels and less interference which can boost performance advantages. However, 5 GHz isn’t as good at going through instance, you should use 5 GHz when for bandwidth hungry use cases like online gaming when a wired connection isn’t possible or high-definition video streaming. But keep your gaming console close to the GHz goes further. The lower frequency of GHz is better at passing through solid objects and can cover a wider range than 5 GHz. For a comparison across different Wi-Fi standards, here’s a breakdown of different GHz vs 5 GHz speeds and instance, you should use GHz if your Wi-Fi clients and router/access point might be separated by multiple rooms. GHz will do a better job of penetrating walls and objects between your Wi-Fi can use both. It’s also worth keeping in mind that simultaneous dual band routers can broadcast GHz and 5 GHz at the same time. This allows you to use GHz for some devices and 5 GHz for others and can provide more flexibility. Additionally, if the GHz and 5 GHz networks use the same SSID service set identifier Wi-Fi network name, wireless devices can automatically connect to their preferred bandwidth. In short simultaneous dual band routers and modern smart devices can automatically do a lot of the work for is Wi-Fi Channel Width?When you’re making a decision among 20 MHz vs 40 MHz vs 80 MHz vs 160 MHz what you’re doing is picking a channel got an introduction to Wi-Fi channels above. We saw that the GHz Wi-Fi band is chopped up into smaller 20 MHz bands for use. These smaller bands are the channels that Wi-Fi devices communicate on. The channel width is simply the frequency range for the MHz and 40 MHz What’s the Difference?When dealing with Wi-Fi, channel widths are usually measured in megahertz MHz. 20 MHz was the norm and only option for channel width in and Wi-Fi more on the standards below. The standard introduced channel bonding, which enabled 40 MHz widths. further extended bonding to allow for 80 MHz and 160 MHz channels increases throughput, which can improve performance. Thus, the difference between 20 MHz and 40 MHz is throughput. 40 MHz has higher throughput than 20 MHz thanks to channel are downsides to channel bonding. While 40 Mhz might have higher throughput than 20 Mhz, it also reduces the number of non-overlapping channels. This increases the probability for interference. Additionally, not all Wi-Fi client devices support channels other than 20 MHz so compatibility can be a note on marketing lingo and tech talk 20 MHz Wi-Fi channels are generally referred to as “narrow channels” or “narrow widths”. 40, 80, and 160 MHz Wi-Fi channels are labeled “wide channels” or “wide widths”Understanding IEEE StandardsIf you are exploring router specs, studying for a Network+, or trying to determine Wi-Fi compatibility, has likely come up. IEEE develops the Wi-Fi standards, and these standards dictate what speeds and frequencies are is a quick rundown on the well-known IEEE standards was an early 5 GHz 54 Mbps Wi-Fi was a popular early GHz 11 Mbps version of increased GHz Wi-Fi speeds up to 54 “Wi-Fi 4″supports both GHz and 5 GHz Wi-Fi at speeds up to 450 “Wi-Fi 5” supports 5 GHz only and speeds of up to 1300 “Wi-Fi 6” is slated for final approvals in September and November of 2020. However, there is already Wi-Fi 6 technology on the market. V Even in 2019, vendors were releasing products based on earlier drafts. supports both GHz and 5 GHz and has a maximum speed of up to 10 and tend to be the most popular standards available today. You can expect to grow in popularity over the next few is important to note that maximum theoretical speeds are NOT the same as real-world speeds. In other words With any given Wi-Fi version, you can expect slower actual speeds than the max speeds listed about 6 GHz and Wi-Fi 6E?In April of 2020, the FCC announced they will open up the 6 GHz band for Wi-Fi and other unlicensed use. The additional 1,200 MHz is the biggest addition of usable spectrum in decades. Wi-Fi 6 devices capable of using the 6 GHz bands will be known as “Wi-Fi 6E”. The “E” signifies the extension into the 6GHz 6E devices aren’t readily available today, but you can expect to see them on the market in late 2020 and early short Wi-Fi 6E will enable some big improvements, but it’ll be some time before it becomes the Dual Band Wi-Fi?Dual band refers to Wi-Fi routers that support both GHz and 5 GHz bands. Using a dual band router allows you to get the “best of both worlds”. Higher speeds and lower interference for 5 GHz devices, and wider range for GHz devices. It is very common for modern Wi-Fi routers to support dual band Ghz WiFi 20 MHz vs 40 MHz vs 80 MHzIf you’re using GHz, the answer is simple. The best bandwidth for Ghz is 20 the majority of cases, using wide widths on GHz isn’t performance tradeoffs from interference on overlapping channels will likely outweigh the throughput benefits. One possible exception to this rule is remote areas where there are not many other Wi-Fi networks or GHz Wi-Fi and 20 MHz channel widths offers the broadest range of client device support. If you need to support legacy devices and Wi-Fi standards like or you’ll need GHz and 20 Ghz Wi-Fi 20 MHz vs 40 MHz vs 80 MHzWith 5 GHZ, things get a bit less straightforward. There are valid use cases for multiple different Wi-Fi channel widths. The best bandwidth for 5 Ghz is 40 MHz. However, there are other considerations as Ghz Wi-Fi When to Use 20 MHzIf you have a 5 GHz router, consider using 20 MHz for maximizing the amount of non-overlapping channels. Regardless of using GHz or 5 GHz, 20 MHz leaves you with the largest amount of non-overlapping channels. 20 MHz makes sense for high-density deployments and areas where interference is a major Ghz Wi-Fi When to Use 40 MHzUse 40 MHz to strike a balance between minimizing interference and maximizing MHz offers more throughput than 20 MHz. It still leaves room for a dozen or so non-overlapping channels. This enables you to improve performance relative to 20 MHz, and without risking the interference associated with 80 Ghz Wi-Fi When to Use 80 MHzIf Wi-Fi clients are close to your router, your Wi-Fi devices support 80 MHz, interference isn’t a big issue, and you want to maximize throughput, consider 80 all your devices support it, and overlapping channels is not an issue, 80 MHz channels leave you with four or five non-overlapping channels. This increases the likelihood for interference. Additionally, clients often need to be very close < 15 feet to the Wi-Fi radio to get the most out of 80 are two common use cases for 80 MHz mesh backhaul and bridging. However, any application where distances are minimal and there isn’t too much congestion can make sense for 80 the takeaway here is that you must strike a balance between compatibility, throughput, and interference. While it seems intuitive that the right answer is always “up the width if you can”, it just isn’t that from overlapping channels can wreak havoc on network speeds, so you must account for it. This is particularly important in cities, industrial areas, and large businesses where high levels of wireless traffic are to Use 160 MHzAt this point, the use cases for 160 MHz are limited. However, as Wi-Fi 6 grows in popularity, we can expect to see use of 160 MHz widths grow as well. With 160 MHz, there is only one available non-overlapping channel, so there will be interference tradeoffs to consider with 160 course, the 6GHz band and Wi-Fi 6E will change this narrative in the near future. The additional spectrum in the 6 GHz band will allow for 14 more 80 MHz channels or 7 more 160 MHz to Automate Wi-Fi Channel and Width SelectionAs you can see, there’s quite a bit to selecting Wi-FI channel and width selection. However, there are ways to automate the example, some Wi-Fi routers enable automatic detection and use of a channel size based on network conditions. This is usually achieved by selecting “Auto 20/40” or similar option as your channel width. Similarly, with most routers and devices, channel selection can be negotiated automatically. If you’re not experiencing issues, and aren’t looking to optimize performance, sticking with these settings makes Can I Check for Wi-Fi Interference?If you are looking to optimise performance, a Wi-Fi network analyzer may help. Wireless network analyzers can help you identify interference on different channels and select the least noisy option. Alternatively, manually switching between channels and observing performance is a less scientific the Right Wi-Fi ChannelWhen it comes to selecting the right Wi-Fi channel width, every situation is different. By understanding the fundamentals, you can more effectively select a configuration that works best for you. While there is no one-size-fits all answer to the “20 MHz, 40 MHz, or 80 MHz?” question. However, understanding GHz vs 5 GHz frequencies and the tradeoffs between non-overlapping channels and speed goes a long us for your wireless networking needs. ICS Technologies is located in Brisbane, Australia with subcontractors across the country. From Linksys's website NOTE The wireless network modes for a Linksys Dual-Band router will vary depending on the frequency bands you choose to enable. In the GHz frequency, the Wi-Fi signal range is divided into channels each at 5 MHz interval. Adjacent channels overlap and will interfere with each other at 20 MHz block. Setting the channel width to 40 MHz network will allow you to use 2/3 of the entire Wi-Fi band. Thus having a higher chance of overlapping and interfering with other wireless networks. Meanwhile, if you set the channel width to 20 MHz, the network will only overlap with the two channels before and after that frequency. You won't get better speed by doing that change. You may get better signal, but there's a downside to it. Essentially, you will have a higher chance to have collisions with other wireless networks around you. I would keep it at 20 just so you have less packet loss. Dual-band routers essentially give you two access points with each having their own bandwidth in them. Usually one AP will be in the range and the other will be in the range. Within each spectrum, there are several Wi-Fi modes that you can enable. The fastest will be Wireless N, with speeds of 300Mbps. However, that 300Mbps is shared between all devices connected to that AP. For example, if you have 5 devices in the 5GHz AP and one is using up 200Mbps, then the other 4 devices on the 5GHz AP will have 100Mbps to work with. However, both AP's are isolated from each other wirelessly anyways; they have the same IP address so devices on different APs can still contact each other, so if you have two data-hungry wireless devices you could put one in the AP and another in the APassuming it supports 5GHz Wi-Fi. If you want to get the fastest speed out of your router, enable both the and the APs, configure them with wireless N, and split your devices across each network evenly one by one.
