# 1.4.8 Overloading

Overloading threshold is the minimum interfering signal levelat which the receiver loses its ability to discriminate against interfering signals at frequencies other than that of the wanted signal. See Annex [A2.2](https://ecowiki.atlassian.net/wiki/spaces/SH/pages/492456/A2.2+OVERLOADING+CASE#A2.2OVERLOADINGCASE-A2.2 "https://ecowiki.atlassian.net/wiki/spaces/SH/pages/492456/A2.2+OVERLOADING+CASE#A2.2OVERLOADINGCASE-A2.2") for the use of overloading in interference calculation and Annex [A5.4](https://ecowiki.atlassian.net/wiki/spaces/SH/pages/492248/A5.4+OVERLOADING+CALCULATION#A5.4OVERLOADINGCALCULATION-A5.4 "https://ecowiki.atlassian.net/wiki/spaces/SH/pages/492248/A5.4+OVERLOADING+CALCULATION#A5.4OVERLOADINGCALCULATION-A5.4"). for the iRSS<sub data-renderer-mark="true">overloading</sub> calculation.
