IAP-335, how activate VHT160 Mhz with Intel AC-9260?

"IAP-335 Supports up to 1,733 Mbps in the 5 GHz band (with 4SS/VHT80 or 2SS/VHT160"

I have 2x iap-325 + 1x iap-335 (8.3.0.0_64659)

How can I activate / use the maximum channel width 160Mhz?

If the Windows client is connected to the IAP-335, the connection speed will not increase. 867.jpg

 

Intel AC-9260 (Driver 20.50.0.4)

 

There is only the option 80Mhz!?

Hi Matthias,

 

It can only be enabled via CLI as of now.

IAP(config)#arm

IAP (ARM) # ?

160mhz-support                        160MHz Support Mode - none/auto/contiguous-only/non-contiguous-only

Do you really need 160mhz channels?

More width channels give less available channels without overlap. What can cause more interference.

So with width channel use, your client can show you higher connected speed. But the cause of interferance will sends more of tcp retransmissions and actually drops down the goodputh speed (real speed).

Also care that with160mhz channels you also use DFS channels that can cause AP’s are stop sending when a airplan/weather radar etc. is detected.

Beter stay at lower channels for more stability. But all depends on the envoirnment

@Nitesh Singla

Thank you for the right hint.

The data transfer rate has increased from about 60 Mbps (megabytes) to over 100 Mbps.

@marcelkoedijk

IAP-335 -> multi-gig Ethernet + 160Mhz channel width
Are there any more important reasons for the iap-335?

It's exactly what sets him apart from the other (cheaper) models.

In my case the right decision. But I will observe the behavior in operation.

The AP-335 has more antennas (12), and therefore better for high density locations. And in contrast to the 305/315, the AP-335 has a smartrate port through which the AP can be connected to max. 5Gb uplink over standard cabling (this requires a switch with smartrate support). The two uplink interfaces are intended to use port1 for 5GHZ traffic port2 to be used for 2.4GHZ traffic. Indeed a very nice access point.

 

Yes the accesspoints are suitable for 160mhz bandwidth. But everything stands or falls with an RF design plan. With 160mhz channels, there are fewer free channels available in the spectrum, so you will quickly run into co-channel interference and that should always be prevented. Because you have fewer free channels available you will almost immediately use DFS channels. When radar signals are detected in the DFS band, these must also be avoided.

 

You can try 160mhz and see how it works. but usually the golden rule "Less is More" applies. But of course everything depends on the design of the environment.
