What are the similarities and the differences between AMPS and GSM? Explain clearly.
What will be an ideal response?
The major difference between AMPS and GSM is that AMPS uses analog
technology while GSM uses digital technology. AMPS has poor performance
for data transfer while GSM has higher data transfer. GSM features a
subscriber identity module (SIM) known as smart card, which holds all of
subscriber’s personal information (including his phone number) and phone
settings, in AMPS only its HLR contain that data. AMPS and GSM support
roaming, but GSM allows for different system compatibility, hence a user can
travel from one system to the other. Both systems use control channels to
initiate calls, AMPS uses 21 control channels while GSM uses 3 control
channels. AMPS is less secure than GSM.
