摘要: A system and a method are presented for determining when to exit an existing wireless communications coverage network. The comprising calculator circuit (300) sampling received input power levels (702); comparing the level samples predetermined baseline threshold value (704); adjusting indicator responsive compared (707); setting terminal condition indicating device should network (709); exiting based on comparison of (711, 714).
