1GPRS (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

3times 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:Cell with 1 Frequency channel:

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

for Packet switched.

5Unit Description ST55

The mechanical concept of the ST55 as a bar phone type is much similar with other Siemens

series mobile phones.

ST55 can be divided into three main physical blocks, the top cover, middle frame and base cover.

The top cover is composed of internal and external LCD protected by LCD base and lens with

shielding effect. The LCD Lens will joint receiver and top cover.

For the main function assy., there are 2 screws located on the base and 2 on the M/B.

Screwdriver (T5) and tweezers will be used as main tools to perform mechanical repair.

Inside, the middle frame consist a M/B, which carries control and RF section of the mobile, and a

key PCB and microphone directly insert into plug-in connectors to show function. The display

module and vibrator are connected to the board by the board to board connector which is

inserted into a plug-in connector. In case they are defective electrically or mechanically it can be

exchanged very quickly. Camera module and antenna is attached on antenna frame which is

inserted on middle frame. The I/O connector for software upgrading and charging is located on

the bottom of middle frame.

The connector for external RF cable is located at the base cover of the mobile. Battery is

attached on the base cover and fix position with battery knob.

Notice: The ST55 is a dual-band mobile operating on GSM900 and GSM1800.

6Disassembly of ST55

Note: ESD concept; the internal circuits will be more susceptible to ESD because of the use of exchangeable

housing. The construction of the internal block must be/is designed, in the best possible way, to protect the circuit

against sparks.

Attention: Do not touch the screen of the display module when the upper case is removed! The module is damaged

after finger contact! Use a protection foil during disassembly and do not forget to remove this foil during reassembly.

The keypad must be completely closed to prevent any occurrence of an ESD disruptive discharge.

The SIM contacts may be open, thus reachable for ESD contact discharge. This could lead to damage or destruction of

the IC pins.

It is a requirement for the service personnel to observe ESD protection rules while performing servicing the ST55.

For assembly a torque T5 screw driver adjusted to 7Ncm is required.

Step 1

Remove BATTERY, CARKIT RUBBER and 2 SCREWS

(M1.6*6.5) located on BASE CASE ASSY.

Step 2

Detach the TOP CASE ASSY. by sliding the upper gap

from bottom to both sides.

Step 3

Remove the KEYSET from TOP CASE ASSY.

Step 4

Add a protect membrane on LCD. Remove 2 SCREWS

(M1.6*6.5) on top.
