I know with computers 1 and 0 are deciphered by currents being turned on and off. With digital cellular, is there one frequency the phone is listening to, and when the phone 'sees' this frequency, it's picked up as 1 and when 0 is 'sent', there is no transmission of that frequency or is it listening to two frequencies. 1 for '1' and another for '0'?? M.
not quite.... a didgital device is a really fancy walkie talkie... (a radio that looks for a signal form a tower)... the voice conversation is digitized (converted from analog to a digital packet (similar to digital audio .wav files)... this digital packet is encrypted and sent thru a tower to a device that has a bunch of different names... the most common is a switch...where it is decrypted sent along a trunk to its destination... if its another digital cel... its encrypted again.... the 1's and 0's are the encryption... not the frequency
Yes, but doesnt the frequency have to change in order to represent the 1's and 0's bein sent? You can't be on a frequency that doesn't change, then the information being send wouldnt change? If you're on a GSM system, and you're on whatever channel, slot 2, when the tower is sending the phone your information which I know is sent thru packets, the frequency has to modulate to send the information (the 1's and 0's) to the phone? Is it one frequency that's on and off to represent 1's and 0's or does it rotate between 2?
