Hello All,
I would like to know how the mobile knows which frequency(2G/3G/4G) it is using while communicating?
for e.g. when i am moving, sometimes mobile shows it is in 3G network and sometimes in 4G Network. so i want to know when mobile network switch from 3G to 4G or vice versa, what really happens inside the mobile (hardware level)?
Thank you in advance.
