4  Receiver blocking
 (1) At frequencies in:
(a) for radiocommunications receivers operating in 814 MHz to 845 MHz – the frequency range 794 MHz to 869 MHz;
(b) for radiocommunications receivers operating in 890 MHz to 915 MHz – the frequency range 860 MHz to 935 MHz;
  a receiver blocking level greater than or equal to the following figures above the sensitivity level for interfering signals in the frequency ranges set out below is required:

Receiver Occupied Bandwidth   Frequency offsets from the upper and lower frequency limit of the spectrum licence receiver  Minimum blocking requirement (dB)
 20 MHz                      > 5 MHz                                                                                      53
≥ 20 MHz                       > 20 MHz                                                                                    46

Note: The values in the table above are the ratio between the received unwanted signal power at the defined frequency offset and the receiver's sensitivity level.
 (2) At frequencies in the frequency range 1 MHz to 12750 MHz, excluding frequencies ranges to which subclause 4(1) applies, the receiver blocking requirement is a total mean power of -15 dBm.
