phone signal analysis
GSM uses a combination of frequency division multiple access (FDMA) and time division multiple access (TDMA). What this means in
reality is that within each band there are a hundred or so available carrier frequencies on 200kHz spacing (the FDMA bit), and each carrier is broken up into
time-slots so as to support 8 separate conversations (the TDMA bit) |

Wireless short
message service
SMS, short message service is a mechanism of delivery of
short messages over the mobile networks. It is a store and forward way of
transmitting messages to and from mobiles. The message (text only) from the
sending mobile is stored in a central short message center (SMS) which then
forwards it to the destination mobile |
