GPRS has several classes (multislot classes) which are relevant for the transmission
speed. The classes provide the maximum transmission speed for uplink and downlink.
The table below shows the number of time slots for the classes, which can be used for
uplink, downlink, and for the device altogether.
GPRS devices support all variants up to their own multislots.

The maximum possible data rate therefore depends on the multislot class of the device.
The above table shows the available time slots (TS) of a device; the table below shows
the maximum data rate. The data rate, on the other hand, depends on the used coding
scheme (CS). This information is unfortunately not available for the user. The network
providers use different coding schemes according to the reception situation.
