Many common terms in RF engineering are used differently depending on the specific community where they are used. The following gives an example (non exhaustive) of the variety of terms that you can find.
C (i.e. the wanted signal level) is referred to in different radio standards and documents as follows. It is specified for a given sensitivity and a given desensitisation.
- Useful signal (ETSI TS 145.005 - Chapters 5.1.2 and 5.1.3);
- Wanted signal mean power (ETSI TS 136.104 - Table 7.5.1-1);
- Pw (ETSI TS 136.101 - Table 7.6.3.1-1);
- Prefsens + desensitisation (ETSI TS 136.104 - Table 7.5.1-1, ETSI TS 136.101 - Table 7.6.3.1-1) ;
- “C”.
IOOB (i.e. the allowed power of an interfering blocking signal as specified by the standard) is referred to in different standards as follows. It is specified for a given frequency offset, a given sensitivity and a given desensitisation.
- Blocking signal level (ETSI TS 145.005 - Table 5.1-2a);
- Puw (ETSI TS 136.101 - Table 7.6.3.1-1);
- Interfering signal mean power (ETSI TS 136.104 - Table 7.5.1-1).
Sensitivity is referred to in different standards as:
- Reference sensitivity level (ETSI TS 145.005 - Tables 6.2-1x);
- Reference sensitivity (ETSI TS 136.101 - Table 7.3.1-1);
- Reference sensitivity power level (ETSI TS 136.104 - Tables 7.2.1-1 and 7.2.1-2);
- Prefsens (ETSI TS 136.101 - Table 7.3.1-1, ETSI TS 136.104 - Tables 7.2.1-1 and 7.2.1-2).
