GPRS

GPRS is the data wireless application of GSM cellular networks.  GSM itself is perhaps the most widely used digital cellular network popular in Europe, Asia, and now also in America.  Nextel iDEN networks operate really very similar to GSM also.  Of course with such wide usage of GSM cellular voice phones, it is not surprising that these cellular systems would wish a data application that can also run on their cellular networks.

GPRS at times of low traffic may in fact be capable of high data traffic.  The reason for this is that the GPRS application does allow for multiple GSM channels to be used for high data movement - assuming of course that those GSM channels are available and are not in usage for voice.  The more channels that are available the more data can be moved per unit of time, and hence the data will be seen as much higher speed than one might expect from just one channel.
