Conclusion

Care must be taken when measuring adjacent and alternate channel rejection since the

interferer signal characteristics greatly affect results. The only unambiguous interferer signal

waveforms to use for IC comparison are an ideal 802.15.4 signal and a CW tone.

The use of a filtered 15.4 signal is not representative of a real world scenario, and is not well

enough specified to ensure consistency between manufacturers.
