802.15.4 on 900Mhz?

, , ,

We have a system that is currently running on XBP24’s using the XBEE PRO 802.15.4 function set. We are experiencing unacceptable RF interference at this frequency, so would like to do a software-independent conversion to 900Mhz radios such as the XBP9B-dmut-022. However, I’m not seeing where I can install 802.15.4 firmware on that module.

Can you please tell me which 900Mhz module I can get that supports 802.15.4?

Thank you,
