Tool/software: Linux

Hello all,

In our mesh application we want to achieve the maximum throughput ( up to 150 Mbps) with 'n' mode SISO

Operating frequency is 2.4GHz and Bandwidth is 40MHz

What should be the combination of parameters in Hostapd.conf(/usr/share/wl18xx) and sae.conf(/etc/sae.conf) . Below are some trials and their observation,

		Before Setting (72 Mbps)	After Setting (135 Mbps)	For 150 Mbps
Hostapd.conf	hw_mode	g	g	?
	ieee80211n	11	1	?
	channel	[SHORT-GI-20][GF]	7	?
	ht_capab	11g	[HT40+]	?
sae.conf	band	11	11g	?
	htmode	g	HT40+	?
	channel	11	7	?

Hi ,
I don't believe we support 2.4 GHz 40MHz channel in mesh mode - 40 MHz channel is supported in 5 GHz band . Check out section 7.3 : www.ti.com/.../swru423a.pdf
For higher throughput you may use 2.4GHz MIMO mode or 5 GHz 40 MHz

Hello Saurabh,

We have tried for 2.4GHz 40MHz channel and we found the throughput as 130Mbps

Que. 1 : What would be the implications if we continued with the said configurations ?

Hi,
This configuration is not tested by us . It may still work , but we won't be able to comment on it's performance .

Thanks
Saurabh

Thanks Saurabh for that quick response
Just want to ask, what changes do we need to make in the 'Hostapd.conf' and 'sae.conf' files if we want to achieve 150Mbps speed with 2.4GHz 40MHz channel ?

Hi Anurag ,
Since we don't officially support this mode - we won't be able to comment on this.

Thanks

We did the above configuration and it seems to be working fine however do you have any brief reason regarding its implication and why it's not been recommended by T.I. ?

Hi ,
We have not tested the feature configuration mentioned above - that doesn't mean it won't work , it's just that we cannot comment on it since we didn't test it .

Thanks
Saurabh
