Spectrum Management Agency has announced its intentions to revise its regulations for LIPDs. Comments are due by May 2, 1997. It appears that the text of the European Standard for Short Range Devices, I-ETS 300330 is being adopted in the form of AS4268.1 -- 1996; however, SMA has indicated exceptions to the limits. The exceptions are stated in Table ZZ1 in Appendix ZZ, "Variations for Australia (Normative)".
The difference between the European transmitter limits and the Australian transmitter limits are large. As an example, in the range of 20-70 kHz, the difference is 12.5 vs 72 dBuA/m @ 10m, Australia vs Europe respectively. This level is lower than the low frequency spurious limits identified in the European version of the standard. My guess is that there must be a difference in measurement practices. Does anyone know anything about the basis for the proposed Australian limits or the measurement practice used? Have I misinterpreted the limits or applicable tables? Any other forum that this question should be forwarded to? Any comments would be greatly appreciated. Don Umbdenstock
