 What does the GPRS Class 10, Class B mean ?
 GPRS Class 10:
- Mobile telephones differ in the number of channels that they can
bundle. The reason for this is simple. The more time slices
allocated, the more energy consumed by the device sending the
signal. The higher is the GPRS class, the higher is the data speed
(transfer or receive). The highest class of GPRS (Global Packet
Radio Service) you have, the more efficient services you get.
Class 10 means the ability to manage 4 time slots for downloads
or 2 time slots for uploads simultaneously. Today, class 10 is the
highest class used for mobile phones.
 GPRS Class B:
- The definition of mobile telephones supporting GPRS class B is,
that the mobile telephones can be attached to both GPRS and
other GSM services, but the mobile telephones can support either
a voice connection or a data connection. Trying to establish a
simultaneous connection with both does not work. Switching
between one service and the other happens automatically.
