LoRaWAN defines a specific set of data rates in the regional paramter technical specification (RP002), but the LoRa chip and/or PHY is more capable. The SX1272 supports data rates from 0.3 to 37.5kbps and the SX1276 0.018 to 37.5kbps. Llater generation parts also offer support for Spreading Factor 5, increasing the throughput even further.
The LoRa modem is capable of co-channel GMSK rejection of up to 19.5 dB or stated differently, it can receive signals 19.5dB below an interfering signal or the noise floor. This immunity to interference permits the simple coexistence of LoRa modulated systems either in bands of heavy spectral usage or in hybrid communication networks that use LoRa to extend range when legacy modulation schemes fail.
The latest generation of LoRa transceivers extends this capability with the addition of the Long Interleaver. The Long Interleaver increases the resistance to burst interferers during reception, even if their power exceeds 19.5dB above the co-channel resistance specification.
