A Range of Wireless Radio Networks

The GSM was designed to enable voice call in a mobile environment. Though it was originally designed to transport voice numerically — that is the analogic wave of the sounds produced by the voice is transformed into numeric values and then lossy compressed in realtime — the transport of data was not envisaged. Only short messages (SMS) was there from the beginning though commercial application arrived few years later.

Transporting pure data require many features from a network in order to expose low latency and high bandwith. These features were absent at the beginning. Nevertheless, early modification at software level enabled data exchange over the radio network. But it was very slow. Additionally, it suffered from the fact that once connected, you were charged by the operator whatever you exchange data or not: this is due to the airtime consumption of the "call".
The first real data bearer technology was GPRS network. It brought speed and users are charged only for the amount of data transported over the network.

Since then, successive improvements of the network technology — radio, hardware and software — brought continuous performances improvements and usability.

Networks Performances

Below is the list of all exiting network technologies and the performance you can expect in the real life.

Name	G	Bandwidth	Comments	Protocol	Latency
CSD (GSM): Circuit Switched Data	2G	9.6kb/s	N/A†
HSCSD: High Speed Circuit Switched Data	2G	14.4—56.6kb/s‡	N/A†
GPRS: General Packet Radio Service	2.5G	30—60Kb/s‡	Commercially appeared in 1997 —Establishing connection takes up to 3 seconds once. Subsequent connections won't suffer from this additionnal latency. GPRS is very sensible to network conditions and dramatically suffer from busy cells	HTTP	2400 ms (one can have 15s with bad network conditions)
				TCP	1200 ms
				UDP	200 ms
EDGE: Enhanced Data GSM Environment	2.5G+	236.8 kbit/s‡		HTTP	N/A†
				TCP	N/A†
				UDP	N/A†
UMTS: Universal Mobile Telecommunications System	3G	up to 384Kb/s	Commercially appeared in 2005	HTTP	1200 ms
				TCP	600 ms
				UDP	100 ms
HSDPA: High Speed Downlink Packet Access	3.5G	from 1.8Mb/s downlink, (384Kb/s uplink) up to 14.4Mb/s	Commercially appeared in 2006	HTTP	200 ms
				TCP	100 ms
				UDP	N/A†
HSUPA: High Speed Uplink Packet Access	3.75G	up to 5.76Mb/s uplink (up to 14.4Mb/s downlink)	Will probably commercially appear in 2007 or 2008	HTTP	N/A†
				TCP	N/A†
				UDP	N/A†
4G	4G	downlink up to 100Mb/s, downlink up to 50Mb/s	N/A†
