Ing 4G makadaleraya ya keng pangapat a generasiun a cellular wireless ampo ding kayang inalilan a 3G ampong 2G iley (standards). Ing aliwa ning articulu iti tataid ne ing 4G keng International Mobile Telecommunications-Advanced (IMT Advanced), agiang ing 4G maleparan ya kabaldugan at mapaliaring kayabe la reng iley (standards) kilual ning IMT-Advanced. Ing 4G systema maliari nalang itas-antas deng kasalungsungan magagamit a communication networks ampo panaligan dalang mamie malaparan ampong makakambil a IP pagbatayan a solusiun nung nu deng facilidad antimo ing siuala, data ampong mamagus a multimedia mibie la kareng talagamit maski "kapilan" at "nokarin" man king mas mabilis a pulayi nung nu lalawen mo reng mengalabas a generasiun.
