Waxaan ku noolnahay da'dii intarneedka iyo isku xirka wireless-ka, dadka badankiisuna waxay leeyihiin router wireless guryahooda. Wi-Fi waxa ay noqotay erey caan ku ah ereyadayada, laakiin halbeegyada isku xidhka wirelessku ma fududa in la fahmo ama xataa lagu dhawaaqo. Taasi waa sababta oo ah waxay leeyihiin magacyo adag, oo ay ikhtiraaceen injineerada shabakadaha iyo shirkadaha. Ma garanaysaa waxa uu yahay 802.11ax? Ka warran 802.11ad, ama 802.11ac? Ma^(Did) maqashay warka sheegaya in magacyadani isu bedelayaan ereyo fudud sida Wi-Fi 6 , Wi-Fi 5, ama Wi-Fi 4? Ma doonaysaa in aad fahanto waxa ay taasi macnaheedu tahay iyo sababta ay muhiim u tahay? Akhri maqaalkan si aad u hesho macluumaadka aad u baahan tahay:

Isbahaysiga^(Alliance) Wi-Fi ayaa mas'uul ka ah horumarinta heerarka isku xirka wireless

Isbahaysiga Wi-Fi^{(Wi-Fi Alliance)} waa isbahaysiga soosaarayaasha xisaabinta ee adduunka oo dhan kuwaas oo horumariya oo daabaca heerarka isku xidhka Wi-Fi. Dhammaan warshadaha tignoolajiyada ayaa raacaya iyaga oo horumarinaya aaladaha wireless-ka ee ku habboon midba midka kale, iyadoo la kaashanayo heerarka Wi-Fi.

Isbahaysiga^(Alliance) Wi-Fi la'aanteed , ma lahaan karno wada shaqayn wanaagsan oo ka dhaxaysa router-yada wireless-ka iyo aaladaha wireless-ka, sida laptop-kaaga iyo taleefanka casriga ah. Isbahaysiga^(Alliance) Wi-Fi wuxuu daabacaa dhammaan heerarka lagu xusay maqaalkan. Aynu mid mid uga doodno:

Waa maxay 802.11n, oo sidoo kale loo yaqaan Wi-Fi 4?

802.11n, hoostiisa oo buuxa magaca IEEE 802.11n-2009 , waa halbeeg isku xidhka wireless oo la daabacay 2009. Wi-Fi 802.11n waxaa sidoo kale loo yaqaan Wi-Fi 4^{(Wi-Fi 802.11n is also referred to as Wi-Fi 4)} . 802.11n waxa ay ogolanaysaa isticmaalka laba xabbo oo soo noqnoqda raadiyaha, 2.4 GHz iyo 5 GHz , waxana uu gaadhsiin karaa xawaarihii xawaaladaha xogta ilaa 600 Mbps . Wi-Fi 802.11n sidoo kale wuxuu ahaa halbeeggii ugu horreeyay ee bilaa-waayirka ah ee bixiya taageerada MIMO ( wax-soo-saarka-badan-soo-saarka-badan^{(multiple-input-multiple-output)} ). MIMO waa tignoolajiyad u oggolaanaysa isticmaalka anteenooyin badan si ay u gudbiyaan xog badan iyadoo la isku darayo qulqulka xogta madaxbannaan.

Dariiqyada casriga casriga^(Modern) ah waxay isticmaalaan heerka Wi-Fi 4 ee band 2.4 GHz . Wi-Fi 4 waxaa loo isticmaalaa in lagu xidho aaladaha da'da weyn ee shabakada, ama aaladaha guriga ee smart sida furyada smart, nalalka smart, dareemayaasha, iyo wixii la mid ah.

Waa maxay 802.11ac, oo sidoo kale loo yaqaan Wi-Fi 5?

802.11ac ama IEEE 802.11ac waa halbeeg isku xidhka bilaa-waayirka ah oo la daabacay dabayaaqadii 2013. Wi-Fi 802.11ac waxa kale oo loo yaqaan Wi-Fi 5^{(Wi-Fi 802.11ac is also known as Wi-Fi 5)} . 802.11ac waa heerka ugu caansan ee wireless-ka maanta, maadaama inta badan router-yada la iibiyay dhowrkii sano ee la soo dhaafay ay 802.11ac ku habboon yihiin. Heerkan, sida 802.11n ka hor, wuxuu taageeraa MU-MIMO , laakiin wuxuu bixin karaa xawaaraha wareejinta xogta ugu badan ee ilaa 2.3 Gbps . Halbeegga 802.11ac wuxuu ku shaqeeyaa oo keliya xadiga soo noqnoqda ee 5 GHz , laakiin inta badan jiheeyayaasha wireless-ka ee taageera sidoo kale waxay taageero u fidiyaan heerka 802.11n ee xadiga soo noqnoqda ee 2.4 GHz .

Qalabka 802.11ac waxa loo kala qaybiyaa laba qaybood oo kala ah 802.11ac Wave 1 iyo Wave 2 . Alaabooyinka lagu iibiyo qayb ka mid ah 802.11ac Wave 1 waxaa lagu soo bandhigay suuqa 2013, halka kuwa Wave 2 la soo bandhigay 2016. Wave 2 waa nooca la hagaajiyay ee heerka. 802.11ac Wave 2 router-yada bilaa-waayirka ah ayaa leh wax soo saar sare oo taageero ah MU-MIMO : halka Wave 1 router ay ku siin karaan xawaare gaaraya 1.3 Gbps , kuwa Wave 2 ku jira waxay ku gaarsiin karaan xawaare gaaraya 2.3 Gbps. Sidaa darteed, haddii aad soo iibsato router wireless maanta, waa fikrad wanaagsan inaad hubiso inay bixiso taageerada 802.11ac Wave 2 , si aad uga faa'iidaysato hagaajinta xawaaraha iyo caymiska.

Waa maxay 802.11ax?

802.11ax ama IEEE802.11ax waa halbeeg isku xidhka bilaa-waayirka ah kaas oo wali ku jira shaqada oo aan wali la ansixin. Waxa la filayaa in la dhammeeyo oo la ansixiyo wakhti dabayaaqada 2019, sida ay wadaagaan ZDNet: Xiga jiilka 802.11ax wi-fi: Cufan, dhakhso, daahday^{(Next-generation 802.11ax wi-fi: Dense, fast, delayed)} .

802.11ax sidoo kale waxaa loo tixraacaa Wi-Fi 6^{(802.11ax is also referred to as Wi-Fi 6)} . Waxa kale oo loo yaqaan Wireless High-Efficiency Wireless^{(High-Efficiency Wireless)} ( HEW ) waxaana loogu talagalay in lagu shaqeeyo isla 2.4 GHz iyo 5 GHz xadhkaha^(GHz) soo noqnoqda ee heerarka aan soo sheegnay ilaa hadda. Waxay u muuqataa inay sidoo kale awood u yeelan doonto inay la shaqeyso kooxo dheeri ah oo u dhexeeya 1 iyo 7 GHz , marka ay diyaar noqdaan. Heerka isku xirka wireless 802.11ax wuxuu rajeenayaa inuu wanaajiyo celceliska xawaaraha wareejinta xogta ilaa afar jeer in ka badan heerka 802.11ac. Waa in ay bixiso xawli aad u wanagsan, gaar ahaan meelaha dadku ku badan yahay sida garoomada diyaaradaha, saldhigyada tareenada, makhaayadaha, ama dukaamada qaxwada.

Jidadka bilaa- wireless-ka ah iyo nidaamyada Wi-Fi-ga mesh ee^{(mesh Wi-Fi systems)} leh Wi-Fi 6 ayaa mar hore ka soo muuqday suuqa. Si kastaba ha ahaatee, waxay u muuqdaan inay leeyihiin qiimo qaali ah, dadka badankiisuna ma awoodaan. Isla marka heerka la oggolaado oo la dhammeeyo, filo qalab Wi-Fi badan oo la awoodi karo in la bilaabo.

Waa maxay 802.11ad?

IEEE 802.11ad waa halbeeg iskuxiran oo wireless ah oo sidoo kale loo yaqaan WiGig ama 60 GHz Wi-Fi^{(WiGig or 60 GHz Wi-Fi)} . Waa nooc ka mid ah Wi-Fi , halkii laga isticmaali lahaa xadhkaha soo noqnoqda ee wireless-ka caadiga ah sida 2.4 GHz ama 5 GHz , isticmaala qaybta mikrowave ee spectrum raadiyaha, oo ku socda qiyaastii 60 GHz . Waxay u ogolaataa xawaaraha wareejinta xogta si cajiib ah oo ilaa 7 Gbps ah. Si kastaba ha ahaatee, sababtoo ah waxay ku shaqeysaa inta jeer ee kala duwan ee microwave, waxay leedahay faa'iido darro weyn oo ah inaadan awoodin inaad soo gudubto derbiyada waxayna leedahay kala duwanaansho kaliya 3 ilaa 32 cagood (1 ilaa 10 mitir). Waa “hillaac aad u dheereeya,” laakiin waxa loogu talo galay inay daboosho hal qol oo keliya marka aanay gidaar iyo caqabado hor istaagin.

Waxaa jira dhowr router wireless oo suuqa ku jira oo taageero u ah 802.11ad, iyo aalado shabakadeed oo yar oo taageero u ah. Mid ka mid ah router-yada aan ku tijaabinay 802.11ad waa Netgear Nighthawk X10 .

Waa maxay Wi-Fi 6, Wi-Fi 5, Wi-Fi 4, iyo wixii la mid ah?

Oktoobar 3 , 2018, ^{(October 3)}Isbahaysiga^(Alliance) Wi-Fi wuxuu ku dhawaaqay inuu ku daray magac cusub oo^{(new naming)} loogu talagalay heerarka isku xirka wireless, si ay ugu fududaato dadka inay aqoonsadaan. Ka dib oo dhan, 802.11ax, 802.11ad, 802.11ac, 802.11n, iyo dhammaan magacyada kale ee la midka ah ma fududa in la xasuusto, dadka badankiisuna ma garanayaan waxa ay ula jeedaan. Fikirkooda ayaa ah in Wi-Fi , oo ay ku xigto lambar, ay fududahay in la xasuusto. Xeerku waa in mar kasta oo ay tiradu sarrayso, ay cusub tahay oo ay ka sii fiicnaan doonto heerka. Waxaad hore u garanaysay hadda macnaha Wi-Fi 6 , Wi-Fi 5, iyo Wi-Fi 4. Si kastaba ha ahaatee, si loo soo koobo, halkan waa waxa ay yihiin:

• Wi-Fi 6 waxay tilmaamaysaa aaladaha taageera heerka isku xirka wireless 802.11ax
• Wi-Fi 5 waxay tilmaamaysaa aaladaha taageera heerka isku xirka wireless 802.11ac , oo ay ku jiraan 802.11ac ^(802.11ac)Wave 2
• Wi-Fi 4 wuxuu tilmaamayaa aaladaha taageera heerka isku xirka wireless 802.11n

Si lagaaga caawiyo inaad fahamto waxa mid kasta oo ka mid ah heerarka isku xidhka Wi-Fi ee casriga ahi uu bixiyo, waxaanu samaynay miis isbarbar dhigaya xadhkaha soo noqnoqda iyo xawaaraha ugu badan ee aragtida:

Wi-Fi 1, Wi-Fi 2, iyo Wi-Fi 3 lama calaamadin. Taasi waxay u badan tahay sababta oo ah Isbahaysiga^(Alliance) Wi-Fi ma aysan tixgelinin heerarka Wi-Fi ee hore in la isticmaalo wax badan. Si kastaba ha ahaatee, si loo dhamaystiro, waxaan aaminsanahay in sumadeynta saxda ah ay ahaan lahayd:

• Wi-Fi 1 waa inuu ahaadaa 802.11b. Heerkan waxa la sii daayay 1999kii, waxa ay isticmaashaa 2.4 GHz band, waxana ay leedahay xadiga xogta ilaa 11 Mbps .
• Wi-Fi 2 waa inuu ahaadaa 802.11a. Waxaa la sii daayay 1999, waxay isticmaashaa band 5 GHz , waxayna leedahay xadiga xogta ilaa 54 Mbps .
• Wi-Fi 3 waa in uu ahaado 802.11g. Heerkan waxa la sii daayay 2003dii, waxa ay isticmaashaa 2.4 GHz band, waxana ay leedahay xadiga xogta ilaa 54 Mbps .

802.11ax vs 802.11ac vs 802.11n ama Wi-Fi 6 vs Wi-Fi 5 vs Wi-Fi 5, iyo xawaaraha nolosha dhabta ah

Haddii aad akhrido qeexida halbeeg kasta oo Wi-Fi ah, iyo xawaaraha aragtiyeed ee ugu sarreeya ee mid kastaa gaadhi karo, waxaad noqon doontaa mid cajaa'ib leh. Si kastaba ha noqotee, nolosha dhabta ah, xawaaraha aad ku heleyso aad ayuu u hooseeyaa. Waxaad ka heli kartaa wax badan oo ku saabsan mawduucan, maqaalkan: Waa maxay AC1200, AC1750, AC1900 ama ka badan, macnaheedu waa maxay farqiga u dhexeeya?^{(What does AC1200, AC1750, AC1900 or more, mean and what's the difference?)}

Si aan ku siiyo aragti dhab ah oo ku saabsan xawaaraha nolosha dhabta ah ee aad ka hesho heerarka kala duwan ee la heli karo, waxaan qaadnay mid ka mid ah router wireless-ka ugu awoodda badan - ASUS ROG Rapture GT-AX11000 - oo waxaan ku samaynay qaar ka mid ah cabbirada SpeedTest , on laptop leh kaarka shabakadda Intel Wi-Fi 6 AX200 . Xidhiidhka internatkayadu waxa uu bixiyaa xawaaraha soo dejinta ee 1 Gbps , iyo xawaaruhu 500 Mbps .

Marka hore waxaanu ku xidhnay Wi-Fi-ga^(Wi-Fi) uu sii daayo router-ku, oo ku yaal 2.4 GHz band, anagoo adeegsanayna heerka 802.11n ( Wi-Fi 4 ), xawaaraha ugu badan ee aanu ku cabirayna waa 221.28 Mbps .

Ka dib waxaan u wareegnay guutadii 5 GHz ee ugu horeysay ee labada uu sii daayay router, anagoo adeegsanayna heerka 802.11ac ( Wi-Fi 5 ). Xawaaraha ugu badan ee aanu gaadhnay waa 630.10 Mbps . Heerka Wi-Fi 5 ayaa 2.8 jeer ka dheereeya heerka Wi-Fi 4 marka la isticmaalayo router-ka wireless-ka.

Ugu dambeyntii, waxaan u wareegnay kooxda labaad ee 5 GHz , taasoo adeegsatay heerka 802.11ax ( Wi-Fi 6 ). Markan waxaan gaarnay xawaarihii ugu badnaa ee la soo dejinayay 762.03 Mbps . Taasi waa 20% ka dhakhso badan Wi-Fi 5, taas oo ah horumar la taaban karo, laakiin ka fog xawaaraha aragtida ugu badan ee lagu yaboohay heerka Wi-Fi 6 .

Waxaan rajeyneynaa, isbarbardhigga degdegga ah wuxuu ku siiyay aragti dhab ah oo ku saabsan xawaaraha aad ku gaari karto, nolosha dhabta ah, markaad isticmaaleyso heerarka Wi-Fi ee kala duwan.

Raadiyayaasha wirelessku ma isticmaalaan hal ama in ka badan oo Wi-Fi ah?

Haa, badankood way sameeyaan! Soo-saareyaashu waxay sameeyaan router-ka wireless-ka oo ka shaqeyn kara hal, laba, ama xitaa saddex qaybood isku mar, iyagoo taageeraya heerarka kala duwan ee wireless-ka ee koox kasta. Inta badan router-yada wireless-ka maanta waa laba-band ama tri-band router sababtoo ah waxay bixiyaan xawaare badan iyo ku-habboon qalabyo kala duwan. Dhammaan jiheeyayaasha bilaa-waayirka ah ee maanta la iibiyo waxay taageero u hayaan heerka 802.11n (badanaa 2.4 GHz band), iyo sidoo kale ku dar taageerada heerka 802.11ac (oo ku yaal band 5 GHz ). Dariiqyada wireless-ka ee dhamaadka-sare ayaa sameeya intaas oo dhan, laakiin sidoo kale waxaa ku jiri kara koox saddexaad (5 GHz ama xitaa 60 GHz ), taas oo loo isticmaalo heerarka cusub sida 802.11ac Wave 2 , 802.11ax ama 802.11ad.

Haddii aad leedahay hal-band, dual-band, ama tri-band router, waxa wanaagsan ayaa ah in firmware-ku uu kuu ogolaado inaad doorato heerarka Wi-Fi-ga^(Wi-Fi) iyo xargaha aad rabto inaad awood u yeelato oo aad isticmaasho. Waxaad dooran kartaa inaad dhaqaajiso kaliya band 2.4 GHz iyo halbeegyada wirelesska ee lagu taageerayo, ama waxaad dooran kartaa inaad dhaqaajiso kaliya band 5 GHz iyo heerarka wireless-ka ee lagu taageerayo. Intaa waxaa dheer, waxaad awood u siin kartaa dhammaan xargaha iyo dhammaan heerarka wireless-ka ee laga heli karo router-kaaga, isku-darka wax walba si aad u hesho natiijooyinka la rabo ee shabakadaada.

Ma qorsheyneysaa inaad hesho qalab cusub oo taageera heerarka cusub ee Wi-Fi?

Ma^(Are) isticmaaleysaa aaladaha Wi-Fi 5 ku habboon? Ma rumaysan tahay inay mudan tahay in loo cusboonaysiiyo Wi-Fi 6 heerkii ugu dambeeyay, mise waa dhakhso in la maalgashado?

What is 802.11ax, 802.11ad, 802.11ac, and 802.11n? What is Wi-Fi 6, Wi-Fi 5 and so on?

We are living іn the age of the internet and wireless connections, and most pеople have a wirelеss router in their homes. Wi-Fi has become a common term in our νocabulary, but wireless networking standаrds are not easy to underѕtand or even pronounce. That is because they have complicated names, invented by network engіneers and corporations. Do you know what 802.11ax is? What about 802.11ad, or 802.11ac? Did yoυ hear the news that these names are changing into simpler terms like Wi-Fі 6, Wi-Fi 5, or Wi-Fi 4? Do you want to understand what аll thаt means and why it matters? Read this article tо fіnd the information you need:

The Wi-Fi Alliance is in charge of developing wireless networking standards

The Wi-Fi Alliance is an alliance of computing manufacturers from all over the world that develops and publishes the Wi-Fi networking standards. The entire tech industry follows them and develops wireless devices that are compatible with each other, with the help of Wi-Fi standards.

Without the Wi-Fi Alliance, we would not have good interoperability between wireless routers and wireless devices, such as your laptop and smartphone. The Wi-Fi Alliance publishes all the standards covered in this article. Let's discuss them one by one:

What is 802.11n, also known as Wi-Fi 4?

802.11n, under its full name IEEE 802.11n-2009, is a wireless networking standard that was published in 2009. Wi-Fi 802.11n is also referred to as Wi-Fi 4. 802.11n allows the use of two radio frequency bands, 2.4 GHz and 5 GHz, and can deliver data transfer speeds of up to 600 Mbps. Wi-Fi 802.11n was also the first wireless standard that offered support for MIMO (multiple-input-multiple-output). MIMO is a technology that allows the use of multiple antennas to transmit more data by combining independent data streams.

Modern wireless routers use the Wi-Fi 4 standard on the 2.4 GHz band. Wi-Fi 4 is used to connect older devices to the network, or smart home devices like smart plugs, smart bulbs, sensors, and so on.

What is 802.11ac, also known as Wi-Fi 5?

802.11ac or IEEE 802.11ac is a wireless networking standard that was published in late 2013. Wi-Fi 802.11ac is also known as Wi-Fi 5. The 802.11ac is the most common wireless standard today, as most routers sold during the last few years are 802.11ac-compatible. This standard, just like the 802.11n before it, supports MU-MIMO, but it can offer maximum data transfer speeds of up to 2.3 Gbps. The 802.11ac standard works only on the 5 GHz frequency band but most of the wireless routers that support it also offer support for the 802.11n standard on the 2.4 GHz frequency band.

802.11ac devices are split into two categories, called 802.11ac Wave 1 and Wave 2. The products that are sold as part of the 802.11ac Wave 1 were introduced to the market in 2013, while the ones in Wave 2 were introduced in 2016. Wave 2 is an improved version of the standard. The 802.11ac Wave 2 wireless routers have higher throughput and add support for MU-MIMO: while the Wave 1 routers can provide speeds of up to 1.3 Gbps, the ones in Wave 2 can deliver speeds of up to 2.3 Gbps. Therefore, if you buy a wireless router today, it is a good idea to check whether it offers support for 802.11ac Wave 2, to benefit from improved wireless speed and coverage.

What is 802.11ax?

802.11ax or IEEE802.11ax is a wireless networking standard that is still in the works and has not yet been approved. It is expected that it will be finalized and approved sometime during late 2019, as shared by ZDNet: Next-generation 802.11ax wi-fi: Dense, fast, delayed.

802.11ax is also referred to as Wi-Fi 6. It is also known as High-Efficiency Wireless (HEW) and is designed to work in the same 2.4 GHz and 5 GHz frequency bands as the standards that we mentioned so far. It appears that it will also be capable of working with additional bands between 1 and 7 GHz, when they become available. The 802.11ax wireless networking standard aims to improve the average data transfer speeds by up to four times more than the 802.11ac standard. It should offer significantly improved speeds, especially in crowded places such as airports, train stations, restaurants, or coffee shops.

Wireless routers and mesh Wi-Fi systems with Wi-Fi 6 have already shown up on the market. However, they tend to have a premium price, and most people can't afford them. As soon as the standard is approved and finalized, expect more affordable Wi-Fi equipment to be launched.

What is 802.11ad?

IEEE 802.11ad is a wireless networking standard that is also known as WiGig or 60 GHz Wi-Fi. It is a form of Wi-Fi that, instead of using traditional wireless frequency bands such as 2.4 GHz or 5 GHz, uses a microwave section of the radio spectrum, running at about 60 GHz. It allows for incredibly fast data transfer speeds of up to 7 Gbps. However, because it works on a microwave range frequency, it has the significant disadvantage of not being able to pass through walls and has a range of only 3 to 32 feet (1 to 10 meters). It is "lightning fast," but it is designed to cover only one room when no walls or obstacles stand in the way.

There are few wireless routers on the market with support for 802.11ad, and few network devices that have support for it. One of the routers that we tested with 802.11ad is Netgear Nighthawk X10.

What is Wi-Fi 6, Wi-Fi 5, Wi-Fi 4, and so on?

On October 3, 2018, the Wi-Fi Alliance announced that it added a new naming for the wireless networking standards, to make it easier for people to identify them. After all, 802.11ax, 802.11ad, 802.11ac, 802.11n, and all the other similar names are not easy to remember, and most people have no idea what they mean. Their thinking is that Wi-Fi, followed by a number, is easy to remember. The rule is that the higher the number, the newer and the better the standard. You already know by now what Wi-Fi 6, Wi-Fi 5, and Wi-Fi 4 mean. However, to summarize, here is what they are:

• Wi-Fi 6 identifies devices that support the 802.11ax wireless networking standard
• Wi-Fi 5 identifies devices that support the 802.11ac wireless networking standard, including 802.11ac Wave 2
• Wi-Fi 4 identifies devices that support the 802.11n wireless networking standard

To help you understand what each of the modern Wi-Fi networking standards offers, we made a table which compares their frequency bands and maximum theoretical speed:

Wi-Fi 1, Wi-Fi 2, and Wi-Fi 3 are not branded. That is likely because the Wi-Fi Alliance did not consider older Wi-Fi standards to be used much. However, for the sake of completion, we believe that the correct branding would have been:

• Wi-Fi 1 should have been 802.11b. This standard was released in 1999, it uses the 2.4 GHz band, and it has a data rate of up to 11 Mbps.
• Wi-Fi 2 should have been 802.11a. It was released in 1999, it uses the 5 GHz band, and it has a data rate of up to 54 Mbps.
• Wi-Fi 3 should have been 802.11g. This standard was released in 2003, it uses the 2.4 GHz band, and it has a data rate of up to 54 Mbps.

802.11ax vs 802.11ac vs 802.11n or Wi-Fi 6 vs Wi-Fi 5 vs Wi-Fi 5, and real-life speeds

If you read the specifications of each Wi-Fi standard, and the maximum theoretical speed that each can achieve, you are going to be impressed. However, in real life, the speeds you get are much lower. You can find out more about this subject, in this article: What does AC1200, AC1750, AC1900 or more, mean and what's the difference?

To give you a realistic perspective on the real-life speed you get from the different standards that are available, we took one of the most powerful wireless routers - ASUS ROG Rapture GT-AX11000 - and made some measurements with SpeedTest, on a laptop with an Intel Wi-Fi 6 AX200 network card. Our internet connection offers a download speed of 1 Gbps, and an upload speed of 500 Mbps.

We first connected to the Wi-Fi emitted by the router, on the 2.4 GHz band, using the 802.11n (Wi-Fi 4) standard, and the maximum download speed we measured is of 221.28 Mbps.

We then switched to the first 5 GHz band of the two emitted by the router, using the 802.11ac (Wi-Fi 5) standard. The maximum download speed that we reached is 630.10 Mbps. The Wi-Fi 5 standard is 2.8 times faster than the Wi-Fi 4 standard when using this wireless router.

Lastly, we switched to the second 5 GHz band, which used the 802.11ax (Wi-Fi 6) standard. This time we reached a maximum download speed of 762.03 Mbps. That is 20% faster than Wi-Fi 5, which is a substantial improvement, but far from the maximum theoretical speeds that are promised by the Wi-Fi 6 standard.

Hopefully, this quick comparison has given you a more realistic perspective of the speeds you can achieve, in real life, when using different Wi-Fi standards.

Do wireless routers use one or more Wi-Fi standards?

Yes, most of them do! Manufacturers make wireless routers that can work on one, two, or even three bands simultaneously, while supporting different wireless standards on each band. Most wireless routers today are dual-band or tri-band routers because they offer more speed and compatibility with various devices. All the wireless routers sold today have support for the 802.11n standard (usually on the 2.4 GHz band), and also add support for the 802.11ac standard (on the 5 GHz band). High-end wireless routers do all that, but can also include a third band (5 GHz or even 60 GHz), that is used for newer standards such as 802.11ac Wave 2, 802.11ax or 802.11ad.

Whether you have a single-band, dual-band, or tri-band router, the good thing is that the firmware should let you choose what Wi-Fi standards and bands you want to enable and use. You can select whether to activate only the 2.4 GHz band and the wireless standards supported on it, or you can choose to activate only the 5 GHz band and the wireless standards supported on it. Furthermore, you can also enable all the bands and all the wireless standards available on your router, mixing everything to get the desired results for your network.

Do you plan on getting new devices that support newer Wi-Fi standards?

Are you using Wi-Fi 5 compatible devices? Do you believe that it is worth upgrading to the latest Wi-Fi 6 standard, or is it too soon to invest in it? Comment below and share your opinion about all the wireless networking standards, their naming conventions, and features.
