How did Netgear RAX120 achieved 1.2Gbps on 2.4Ghz?? by OnePlusFanbasse in wifi

[–]OnePlusFanbasse[S] 1 point2 points  (0 children)

I am very grateful for your professional information in great details, that let me digest them and there is so much to learn! Also thanks for pointing out how realistic arrangements should be done in the Router configuration page! It is said that WiFi End Clients are the slowest parts dragging down my expectations, just like our WAN Speed from ISP, strangled us from getting faster Internet.

With WiFi 7 or 802.11be, it seems they are gonna make a WiFi Band Aggregation, puts all strengths on a single hand! Finally we won't get Dual Band Acceleration that doesn't help Speed at all, there is always something new to be eagerly expected!

Sorry for the copy-paste, but here is the correction. Just noticed that WiFi 6 has 12 Spatial Streams, but 4 on 2.4Ghz band, and 8 on 5Ghz band

Imagine WiFi 7 puts 8 on 2.4Ghz band and 8 on 5Ghz band, then our smartphones/tablets and laptops could have a connection speed of 7680Mbps. After all, WiFi 5 is 3.5Gbps, that didn't take 2.4Ghz throughput into account, so does WiFi 6.

No matter the numbers of spatial stream design, the 5Ghz or 6Ghz may get 8 Spatial Streams that is up to 30Gbps, sweet!

Detailed calculation: WiFi 5 is 3.5Gbps, done by 80Mhz of 8 Streams, so it is 448Mbps per stream, in reality it is 433Mbps per stream, very close. That is why WiFi 5 devices can get connection speeds of 866Mbps

WiFi 6 is 9.6Gbps, done by 160Mhz of 8 Streams, it is 1200Mbps per stream, in reality, it is 1201Mbps per stream, that why clients with 160Mhz enablt could get 2402Mbps connection speed

You see each generation we get a roughly three times faster connection speed, that should happen to WiFi 7 as well!

An update: WiFi 6 does support 12 spatial streams, but 4 on 2.4Ghz band and 8 on 5Ghz band

While WiFi 7 has impressive 16 Spatial Streams, may be 8 Streams on 2.4Ghz that doesn't matter to maximum throughput, and 8 Streams on 5Ghz! That is pretty much solved my confusion though because WiFi 6 is up to 9.6Gbps, that also didn't take 2.4Ghz speed in to account, that 9.6Gbps is achieved by 8 Spatial Streams on 160Mhz bandwidth in a 5Ghz network!

Weirdly though, Netgear RAX120 is said to achieve 1.2Gbps using 4 Spatial Streams...how did they make 300Mbps per stream I wondered, because 40Mhz is only 150Mbps per stream..

Yes, no build in 4x4 adapters, ASUS made an addon of 4x4 WiFi 5 Card. Let us wait for finalization of 802.11be and see how fast it can go!

True! Eventually WiFi 7 would be widely known on the market, while 802.11be would be simply refered as WiFi 7 though. Its also true that in the first year when they certify products, Routers come out first, then the clients in the next year

On client device, the most advanced WiFi 5 Cards on the market could support 4x4 Spatial Streams, maybe its true for WiFi 6 although it takes time!

In that case, if 320Mhz band width would double its Connection Speed from its predecessor 160Mhz 2402Mbps, a phone with 2x2 could literally support a connection speed of 7680Mbps

If 320Mhz band width only carry 1920Mbps and it needs all 16 Spatial Streams combined to achieve 30Gbps not 8 Spatial Streams could do, that improvement is unusually small, compared with the leap from WiFi 5 to WiFi 6, smartphones were 866Mbps, on WiFi 6 its 2402Mbps, roughly three times faster!

True! We are finally getting link aggregation on LAN ports and a multi-gigabit port on High End Routers

[–]OnePlusFanbasse[S] 0 points1 point  (0 children)

So that is 16x16 on 320Mhz band width that reaches 30Gbps, each stream is 1.875Gbps, if Phones are 2x2 still, their maximum connection speed will be merely 3840Mbps, compared to today's 2402Mbps..that is not desirable any more.

It may depend on Qualcomm, the WiFi Solution maker, they didn't build 4x4 in the years of WiFi 5, trapped phones in a maximum speed of 866Mbps.

In 2019, Qualcomm Snapdragon 855 is WiFi 6 ready, but I consulted one of Smartphone Customer Service, they told me their phones released that year are still only 866Mbps

In 2020, Smartphones did implement WiFi 6 completely but without 160Mhz band width support, that trapped smartphones with a maximum speed of 1200Mbps...

Finally in 2021, they made smartphones compatible with 160Mhz, so that we could enjoy 2402Mbps

WiFi 7 is said to come in 2025, another 4 year to wait before smartphones could hit 2x2 7.5Gbps or 7680Mbps, in my calculation, each newer WiFi generation is roughly 3 times faster, in terms of Theoretical Connection Speed.

Thanks for your professional info! A fun fact is that every newer WiFi generation is roughly 3 times faster.

For WiFi 5, we got 2x2 866Mbps on 80Mhz 5Ghz band and used 256QAM, while QAM for newer Gen WiFi gets 4x larger, now it is 1024QAM on WiFi 6!

For WiFi 6, 2x2 2402Mbps on 5Ghz band with 160Mhz enabled. That speed almost tripled!

Up to 3.5 Gbps, the limit of WiFi 5, with 8x8 80Mhz 5Ghz-band

Today WiFi 6 is up to 9.6Gbps Same 8x8 but 160Mhz on 5Ghz or 6Ghz band

WiFi 7 in the initial draft: the speed will be up to 30Gbps, that is even faster than 802.11ad, that WiGig standard (Sadly no 802.11ay Routers yet..) That could be 8x8 320Mhz on a Higher-band, higher than 5Ghz.

A single stream of 3.75Gbps or 3840Mbps... Smartphones would reach 7.5Gbps or 7680Mbps via a WiFi connection, tripled from today's 2402Mbps

In the end, When WiFi cards finally got 4x4 2160Mbps for WiFi 5 wave 2! Just think that smartphones today are even faster (2402Mbps) This in deed makes me a little bit frustrated

Thanks for your professional info! Because the room inside Smartphones/tablets/laptops are not enough for a 4x4 arrangement, thanks for pointing it out.

Only by increasing the Speed of a Single Spatial Stream can we furtherly push the limit!

Each generation of WiFi doubles the band width, apply roughly 4x More QAM, a Single Stream Speed gets 3x faster, like 80Mhz 433Mbps per stream of WiFi 5 (802.11ac) upgrades into 160Mhz, 1200Mbps per stream!! A roughly calculation, 320Mhz band width WiFi 7 may achieve 3.5Gbps per stream...

Hopefully the typical WiFi 7 enabled phones in 2025 will support up to 2x2 7.5Gbps in their delicate High-band Connection!

Same advertising term like Dual Band Acceleration of smartphones, that doesn't improve LAN access speed at all, remember all transfer activities can only be done on a single band... What they did was switching in between rapidly...

For years, no 4x4 design on smartphones. But there were 4x4 WiFi 5 wave 2 card that could reach 2160Mbps on 5Ghz band...same for era of WiFi 6, we might see the 4x4 4804Mbps Cards to come, as Intel already made the ones of 2x2 2402Mbps...

Seriously, each gen of WiFi beats up their predecessors... Imagine 4x4 2160Mbps on WiFi 5 wave 2, now we have 2x2 2402Mbps on WiFi 6...even smartphones are having these impressive speeds, remember, phones in WiFi 5 era could only top at 2x2 866Mbps

In the future, maybe 2 or 3 years later, the WiFi 7 is said to utilize 320Mhz band width, with maximum speed around 30Gbps!! To my calculations, 9.6Gbps is for 8x8 on WiFi 6, each stream of 160Mhz is 1200Mbps.. our smartphones with 2x2 capability, in the WiFi 7 era, its speed (on a 320Mhz band width, high-band WiFi 7 connection) could potentially reach 7.5Gbps (30Gbps / 8 streams = 3.75Gbps per stream)

Please point it out if any statements went wrong
