Where is the location of TX1 NVRAM and how to modify it

Hi

As title,

Where is the path and location of TX1 NVRAM?
And can we modify it?
We need to improve TX1’s signal distance.
Let us can connect to TX1 in more far distance.

Many thanks.

What kind of signal distance do you want to improve? TX1 module is fixed, and the interface lines length between module and carrier board must follow the OEM DG.

Hi

Sorry, we want to improve wifi signal range.
so does the NVRAM can do any modify for that?
or other parameter of config file can modify?

Many thanks.

Wifi signal range depends on the maximum transmit power and antenna efficiency. The maximum transmit power in wifi module of TX1 has been fixed in firmware per which country you choose. If you want to enhance the signal on specific direction, you can choose polarizing antenna, and you need to tune them by yourselves.

Hi,

So can we modify the country code?
Does it fixed,too?

Does it have any parameters of MCS and data link rate and TX power in NVRAM?
Does it have any improvement in the wifi range if we modify those parameters?

Many thanks.
