I-BMS esebenzayo yokulinganisa umsebenzi inokuqonda ubuninzi obuqhubekayo be-1A yokulinganisa yangoku.Dlulisela ibhetri enye ene-eneji ephezulu kwibhetri enye ene-low-eneji, okanye usebenzise lonke iqela lamandla ukongeza elona bhetri lisezantsi. Ngexesha lenkqubo yokuphunyezwa, amandla asasazwa ngokutsha ngekhonkco lokugcina amandla, ukuze kuqinisekiswe ukuguquguquka kwebhetri owona mlinganiselo mkhulu, phucula ubomi bebhetri kwaye ulibazise ukuguga kwebhetri.
