1 GPRS (General Packet Radio Service)

GPRS is a new non-voice value added services that allows information to be sent and received

across a GSM mobile telephone network. It supplements today’s Circuit Switched Data (CSD)

and Short Message Services (SMS). GPRS involves overlaying a packet based air interface on

the existing circuit switched GSM network. This gives the option to use a packet-based data

service. The information is split into separated but related “packets” before being transmitted and

reassembled at the receiving end. Theoretically, maximum speeds of up to 171.2 kilobits per

second (kbps) are achievable with GPRS using all eight timeslots at the same time. This is about

3 times as fast as the data transmission speed possible over today’s fixed telecommunications

networks and 10 times as fast as current Circuit Switched Data services on GSM networks.

Figure1. Example of GPRS data transmission

Example

1 physical channel for signaling, 4 physical channels for Circuit switched and 3 physical channels

for Packet switched.

5.1 Interface M55 to accessories

The I/O Connector of M55 is the slim Lumberg (identical to SL55, S55/57, C55/2128 and A55).

It is the only electrical interface to the Accessories (no RF – connector). Also it has only one

mechanical interface which is integrated in the design parts.

6 Unit Description M55

M55 is designed with a partly bridgeless keypad module and a color display. The mechanical

design is built around the platform of S55. The housing is built up as a two-component plastic

molding part so that the housing shows an “X-design” with two different colors. The complete

housing is lacquered with a translucent effect varnish, which gives the housing a pearlescent

look. Earpiece and keypad are decorated with IMF in the same color. Behind the earpiece is a

metal mesh located, which is also the sound outlet of the receiver. The display lens is decorated

from its outside with IMD and anti scratch protection.

M55 has the same PCB size as S55, which allows using the same carrier in production.
