1g = analog waves, fdma
2g= security , low data ranges
3g = data information
4g = MIMO 
5g = high data ranges]]> 2020-10-22 13:31:24 UTC https://padlet.com/titorv/mobcomm/wish/852362739 Freddy Joya https://padlet.com/titorv/mobcomm/wish/852363887 MCS

When talk to phone, the microphone has a digital signal (0 or 1).
The antenna receives the digital signal and transmits electromagnetic waves.
Change amplitude, frecuency and phase.
In the Frecuency the digital signal is transmits in low or high waves.]]> 2020-10-22 13:32:09 UTC https://padlet.com/titorv/mobcomm/wish/852366009
