1.6 Understanding Radio Jargon

Many common terms in RF engineering are used differently depending on the specific community where they are used. The following gives a non-exhaustive example of the variety of terms that can be found. 
 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”. 
 
 
   
 I OOB  (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).
