What is the point of an 802.11ac router with 10/100 ethernet?

Hi everyone,


Some MikroTik devices like “SXT Lite 5 AC” have a 10/100 port and support the “AC” standard.
What’s the advantage of the standard “AC” if their port output is 10/100 Mbps?
Do not cause a bottleneck?
What you can use that speed when the 100Mbit cable connection will be a bottleneck?
Is my logic wrong somewhere?
tip: This license is specifically licensed to 3, and I would like to use this device as a point-to-point

Thanks!

Of course you will not be able to transfer more than 100 Mbit/s fullduplex, but you will soon find that in practice the actual speeds on WiFi are much lower than the theoretical maximum, so this normally is not too much of a limitation.

The point is not wasting airtime.

5x SXTAClite will most likely exceed the 100mbps at the AC-base station.
Thus only there a Gigabit port will be needed.

A CPE device doesn’t need a Gigabit port.

between wifi clients you can get more than 100Mbit if the AP has AC support, even if it has 10/100Mbit port.

With AP in N mode and 15 clients speed can reach ~110mbps. In AC mode and AC clients it should reach more than that, so even one client can’t reach more than 100mbps, more clients can reach more than 100mbps because all mikrotik AP’s are gigabit.

SXT Lite 5 AC has a level 3 license. Its not made to be an ap-bridge. Its a CPE device. I doubt you are delivering 100mbps+ to each CPE…

Are the actual speeds of the SXT5HPnD[802.11n] and SXT_Lite_5 AC[802.11ac] devices different for the end user who are connected to ethernet100Mbit/s?
theoretical= (max supported 802.11ac data rate 866Mbit)
The actual speed is about=300Mbps
ethernet port= 100Mbps !?

You really, both of you, just don’t get it.
I rest my case.

Remember your 300 Mbps speed is in a single direction only, actual traffic will be both ways and a 100 Mbps fullduplex ethernet connection could in theory transfer up to 200 Mbps added.
I don’t think you will realistically see 100 Mbps on 802.11n and you are more likely to see it on 802.11ac.

However, when you are concerned about the last bit of performance, don’t buy low-end low-budget devices.

Nice math :slight_smile: So yes, whilst it’s 300mbps in a single direction, a 10/100 port CAN NOT, and NEVER WILL be able to send 300mbps EITHER in FDX or a single direction. Thus, I do concur. Pointless for 10/100 on a AC device. You need gigabit interfaces.

That being said… I’ve seen much, much stranger things from MT before.

Where are your problems?

This 100 MBit Port is only there because it is a CPE Device!

If you want to use all speed you can get buy device without Lite in the name.
