In the LTE networks, the modulations that are used by the base stations are QPSK, 16QAM and 64QAM according to the SNR.

Are the modulations QPSK, 16QAM and 64QAM analog or numeric?

I need to know because I am working in the cellular field (but as a developer).

Thank you in advance!

By "numeric", I assume you mean digital. Yes, LTE uses digital modulation, not analog. LTE is an OFDM format, and quite a lot of digital processing is done before the signal is converted to analog and transmitted. The processing includes modulation of multiple sub-carriers, inverse FFT, adding a cyclic prefix, windowing the edges of the symbols. All that is done digitally.
