What I notice is that there exists a misunderstanding between these concepts.
GSM is the 1st designed wireless data transfer standard.
2nd it is GPRS,
and the 3rd, which will nowadays be implemented, is called UMTS.
Wap is just the presentation data format standard, which can be carried over any of these networks, as wrapped to the underlying architecture.

I fully understand GSM infrastructure from base station transmissions & configuration, site planning, cell angles, the math to work it all out etc etc.
How gsm works.
How gprs is an add-on to the gsm network.
How umts can run along side gsm.
But hey I work in telecoms. So i'm gunna know certain stuff.
Your average Jo will not know without educating them/themselves.
I try to tell people that poor signal inside is not a fault, but it is being interferred with by the walls & surroundings. But that isn't good enough. They won't except that as they expect it to work. Without understanding how the thing even works & what it takes to get a call to connect. Its technical sh1t.

Isn't NTMS (or whatever that old analog technology is called) that is the 1st generation? And GSM was 2nd, GPRS is 2½ and UMTS is 3rd.

@ johndoesacc - yep analogue was first. Its so old I forget about that. Vietnam style backback-batteries & 10 meter aerials, with curly cord attatchment to a nucular emitting handset - great fun
@ Elrond - good man - i like your style.
Kung fu - go wang!

TACS was the old analogue system before GSM

Ok, so it`s time to `clear-up` ur messed-up concepts, cuz some of u r STILL wrong:
There r two systems available: analogue ( TDMA ( and some unimportant derivates), NMT) and digital (GSM, CDMA,UMTS).
`GSM is the 1st designed wireless data transfer standard.`- wrong. Global System for Mobile comunication or Groupe Special Mobile was the first DIGITAL standard for mobile communication (they wanted a voice standard so the business could grow and multiply-that`s standardisation).In another words, this is the first real implementation or the `mobile` concept. What u say about data, was thought of but not in particular, that`s why we still have analogue transfers of 9,6 kbps/sec( and later the 14,4 kbps/sec) . THAT was all about data.
`Isn't NTMS (or whatever that old analog technology is called)`: that would be NMT ( Nordic Mobile Telecomunications) was the first analogue mobile standard but just for the Northern Europe.
`TACS was the old analogue system before GSM `: Yes and no. That was a standard for USA only but this and all the other mobile systems are based on TDMA ( Time Divison Multiple Acces), a standard invented in the 70s by some american ...
So the only system diff`rent of TDMA is the CDMA ( a american concept invented by the good ole US Army, but that`s another shit).
GPRS is a new concept but all in all, based on TDMA and analogue transfer too.
UMTS (universal mobile telecomunications system) is not a data standard but an universal comunication concept that will allow higher data transfers...don`t think that they went all the way of implementing it just for the data transfers.What would the data transfers be without the good-ole voice system?
It`s more than that for every system but that`s the ideea

Analogue used sound waves, How scary is that!
Don't forget iDen, Tetra & the Japs 3g/4g nets

@orangeman:we r still using the sound waves with the digital concept but in a diff'rent way.What u mean is that the analogue systems didn't encode the information transmited/received over the network. 'Digital' means the transmitter encodes the voice while the receiver decodes it at the other end.More reliable,secure and certain u get the whole info.It`s true that the 1st ever mobile system was launched in 1979 in the US,the AMPS (advanced mobile phone service), then Europe with the Nmt in sweden in 1981.
