Turn the raw legal text into a practical explanation grounded in Radiocommunications Advisory Guidelines (Managing Interference to Spectrum Licensed Receivers –700 MHz Band) 2023.
4 Receiver blocking
(1) At frequencies in the following: (a) for radiocommunications receivers operating in 703 MHz to 748 MHz – the frequency range 683 MHz to 768 MHz; (b) for radiocommunications receivers operating in 758 MHz to 803 MHz – the frequency range 738 MHz to 823 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.
