The sub-GHz radio transmission does have lower throughput so it is not made to stream audio or video! The sub-GHz is suited for small packets of data. The data rate is adjustable but its common to stick to around 19.2 Kbit per second. Lower is the rate and better woud be the transmissions.

To use such modules you will need both of them! The radios must be matched in frequency (eg: 433 MHz & 433 MHz will match, 433 MHz & 900 MHz are not).

The both module must use the same encoding schemes. You cannot use a RFM69 900 MHz packet radio together with a RFM9x packet radio (LoRa).
