GPRS
The GPRS (General Packet Radio Service) is an evolution of the GSM system
which keeps the same voice transmission mode but significantly improves the
performance of the data transmission using a “packet” system.
The Gm882 uses the
GPRS system and you
can connect it to your
computer using the
appropriate data cable
(optional or included,
according to the product
type) and this allows a fast
transmission of data and
connection to the Internet
when no connection to the
landline is available.
Data transmission speed
The maximum speed of transmission is approximately 40Kbit per second.
This speed is much faster than with the normal GSM network.
Connection speed
GPRS allows immediate connections and information can be sent and received
whenever necessary.
Efficiency
Packet converting allows the Gm882 GPRS telephone to use the radio
frequencies only during the transmission and reception of data.
The operators can therefore maximise the efficiency of their networks by
allocating their resources according to effective need, and devote the circuit
switching infrastructure solely to the call traffic and reduce the traffic of the SMS
center by using the interconnection between the latter and the GPRS system.
Pricing
With the GPRS system you pay for the service based on the quantity of data
transmitted and not on the duration of the GPRS connection.
The Gm882 GPRS telephone allows you to view the quantity of data
transmitted and received during the GPRS connections and therefore to know
the cost of the connections themselves in other contexts that you can set from
the menu.
To make a GPRS connection you need to set some parameters in menu 4-
8-2 “Settings”. Your service provider will give you these data.
