RB board is compatible with 900MHz RF Card?

Wed Apr 25, 2012 11:15 am

When I installed GZ-901 to RB433GL, winbox show 2GHz.

- RB is not compatible with 900MHz card?
- Or RB is compatible with other company's 900MHz card? If yes, please recommand.
(XR9/UBNT is compatible?)
- Or I have to refer to 900MHz/2.4GHz channel comparison table?

3rd option. The card is actually a 2GHz card, but has a converter. You set 2GHz, it will transmit at 900MHz. You need to ask the manufacturer for conversion table.

When you get that table, you can use "frequency offset" setting in the Wireless interface, to make Winbox show correct values. Just enter the difference in MHz between the 2GHz and 900MHz according to manufacturer table.

Dear Normunds...
how can we find the offset setting under "interface wireless frequency-offset"?

there is no such option, or it must be the 900Mhz card only can see?

Dear Normunds...
this under the version 5.6...
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
interface wireless frequency-offset
bad command name frequency-offset (line 1 column 20)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This under the version V5.15
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
interface wireless frequency-offset
bad command name frequency-offset (line 1 column 20)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

both is 11a card, mean, we cannot see the frequency offset setting there...
