FPX3 is a small, high power (half-watt) multi-channel wide band FM transceiver, operating in the Europe-wide 869.40 - 869.65MHz sub-band. It is also available in the Indian licence free 865-867MHz band (General telemetry and RFID).
RDL2 is a half-duplex multi channel wideband FM transceiver in a BiM series footprint and operates on 433.05-434.79MHz European SRD band. This makes the RDL2 ideally suited to those low power applications where low cost multi-channel operation is required.
