Which modulation technique is used in first generation cellular system?

1G or First Generation Mobile Network is _____? 1G is analog .

Digital modulation keying A digital signal can be used to modulate the amplitude, frequency or phase of a sinusoidal carrier producing three different forms of digital modulation: amplitude-shift keying (ASK), frequency-shift keying (FSK) and phase-shift keying (PSK).1 Şub 2019

The first generation mobile systems are based on analog technology. The first technology uses frequency modulation (FM) and frequency division duplexing (FDD), frequency division multiple access (FDMA). The common signalling channels were used in first generation cellular systems.
