GPRS
(General Packet Radio Services)
Overview.
G
PRS 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.
Example: Cell with 1 Frequency channel:
1 physical channel for signalling, 4 physical channels for Circuit switched
and 3 physical channels for Packet switched

Subscriber Identity Module(SIM)
SIM is a smart card which has a computer and memory chip that is permanently installed in the
mobile equipment. It comes in either the size of a credit card or smaller version known as the
plug-in SIM.
The subscriber information, which includes a unique number called the International Mobile
Subscriber Identity (IMSI) is stored in the SIM card. SIM card identifies the subscriber to the
network.
To protect the SIM card from improper use, a security feature, a four digits personal identification
number(PIN), is built in. The PIN is stored in the card and can be changed by the subscriber.
Any deactivated SIM, due to wrong PIN entry, can be re-activated by the network operator
only.

General Information
Due to different requirements of the markets, the S45/ME45 has different variants, which
broadly classified under International version and Asian version. Marketing name for
international version is S45 and ME45, whereas Asian version for S45 is 6618 and for
ME45 is 3618.
The Asian version (6618/3618) comes with Chinese strokes keypad with the Upper housing
without the silk print of “S45”. International version will comes with normal keypad with the printed
“S45” Upper housing.
The main differences between the S45 and ME45 are:
1. The housings
2. ME45 is shock and water splash proof and S45 is not.
GPRS Services Indentification
To identify whether the phone has a located the GPRS services in your region, the sign GPRS
on top of the phone display will be shown as in Picture 2. In order to attached to the GPRS

for spare parts ordering.
Mechanical Concept
Note: All part numbers are referred to mechanical drawing in Figure 2.2 for S45 &
2.3.for ME45
The mechanical concept of the S35/ME45 differs in various points from the one of the other
Siemens mobile telephones.
The first thing you will experience is how the housing is locked No screws are used to keep
the housing closed even internal of the phone To open the housing, which is kept closed by
catches only, a special opening tool has been defined. For details on disassembly tool
please refer to Photo 2. in this chapter.
Inside, the S45/ME45 consists of 2 PCB boards; on of which is the RF board and the other
is the interface with the Keypad.
Keyboard
The Keyboard will be realised via a separate PCB which will be connected to the main PCB
via board-to-board connector with 12 interconnections. The illumination of the keypads will
be done via high-brightness LEDs (colour: amber 590 nm, driven by 5 mA / LED).
Target for the number of LEDs is 4. If it is not possible to get a homogenious illumination of
the keypad, the LED count must be increased to 6. The LEDs for keypad and display are
supplied from a 2.9V linear regulator (REG1) inside the ASIC. Unlike in P35 there is no
pulse-width-modulation necessary to maintain a constant brightness over battery voltage.
Display Modules
Overview of HW Structure
Due to the LCD-controller shortage in the market, four different LCD-controllers can be
connected to the K45-PCB. Three (Hitachi, Samsung, Rohm) do have nearly a similar
interface to the power supply, the EGOLD+ and the passive components. Thus, all display
modules from various module suppliers can be connected to a single interface by using the
mentioned controllers. The interface is realised by a ZIF connector with 28 interconnections.
Unfortunately, the fourth display controller (Epson type) has a completely different interface
pinning as compared to the three others. Therefore, a separate PCB with a 26-pin ZIFconnector is essential. The different displays can be identified by hardware coding on the
FPC in combination with resistors on PCB.
The displays will be shipped as complete modules from the suppliers. The design consists
of the LCD-cell with a Tape Chip Carrier foil (TCP) and the lightguide. The LEDs for the
backlight will be placed on the K45 PCB.
The display controllers will be driven with a supply voltage of VDD = 2.65V.
For the display module the 4 side-shooter LEDs are mounted on the K45 PCB. The LED
colour is amber with a typical wavelength of 590nm. The maximum current per LED will be
about 5mA. Different LED types are under evaluation. The luminance is targeted to be ≈1.5
cd/ m² with homogeneity fluctuations of max. ≈25%. The luminance will be comparable to
the C25 backlight. The S45 Backlight will be better than the S35.
The Display module is connected to the board by a flexible cable which is inserted into a
socket connector. In case the display is defective electrically or mechanically it can be
exchanged easily.
In opposite to the MMI board of other phones (e.g. S6 and E10) the Speaker/Receiver is
not soldered to the board, but is mechanically fixed on to the Upper housing and electrically
connected to the board by the Speaker’s spring.
To be able to do measurements on and software update of the telephone, an adapter cable
between Molex- and Lumberg connector will be available. See photos in Additional Tools of
Chapter 3.
S45/ME45 comes with an integrated antenna and it is built-in to the back of the lower
housing.
The dust protection frame and the display window are included in the display module.
IrDA
Low-Power infrared data interface, compatible to “IrDA - Infrared Data Association; Serial
Infrared Physical Layer Specification, Version 1.3”, supporting transmission rates up to
115.2kbps (slow IRDA). As a Low-Power-Device, the infrared data interface has a
transmission range of
- 20cm to other Low-Power-Devices and
- 30cm to Standard-Devices
The viewing angle is +/-15° (resulting in 30° viewing cone).
The transmitting diode fulfils the requirements of IEC825-1 Class 1M Eye-Safety.
SIM
SIM cards with supply voltages of 1.8V and 3V are supported.
Vibration Motor
The vibration motor is mounted in the lower case. The electrical connection to the PCB is
realised with pressure contacts.
Power Supply and Integrated Charging
Overview of HW Structure
All the important functions for the power supply of the phone are carried out by the supply
ASIC.
The POWER-pin of the I/O-Connector is for charging the battery with an external power
supply. For accessories which provide a variable charge current, the current will be set via a
further pin SB (current byte) (e.g. S25 chargers corresponding to CarKits etc.).
The standard K45 power supply is unregulated and therefore does not react to the SB
signal, but the SB signal will still be used to distinguish the various power connections.
The following restrictions must be observed:
• The phone cannot be operated without battery inserted.
• The phone will be damaged if the battery is inserted with wrong polarity (the mechanics
of the phone prevent the battery from being put in the wrong way round. The electrics
system assumes that the battery has been inserted correctly. This must be ensured via
suitable QA measures).
Inside the LiIon-battery-pack is a protection-circuit, consisting of a small elecronic circuit and
a polyfuse, to prevent the battery from overcharging, deep discharge and overcurrent
Battery
As a standard battery an Li-Ion battery with a nominal capacity of 840mAh@1 CA, 830mAh
@GSM 2.0/0.2A will be used.
Charging Concept
The battery is charged in the unit itself. The hardware and software is designed for Li-Ion
with 4.2V technology.
Charging is started as soon as the phone is connected to an external charger. If the
phone is not switched on, then charging shall take place in the background (the
customer can see this via the “Charge” symbol in the display). During normal use the
phone is being charged (restrictions: see below).
Charging is enabled via an MOS switch in the phone. This MOS switch closes the circuit
for the external charger to the battery. The processor takes over the control of this switch
depending on the charge level of the battery, whereby a disable function in the STVASIC hardware can override/interrupt the charging in the case of overvoltage of the
battery (only for NEC Batteries).
A third line (SB) shall be used for recognition and control of the S2x charger The SB will
be set at a constant 141, which corresponds to a current of 600mA. To distinguish the
charging units the C25 charger (150mA charging current) will have a short circuit to the
ground, whereas the rapid charger, S25 (1A maximum charging current) will have a high
impedance input. The K45 NAG and the P35 NAG will also be fitted with a high
impedance input and will therefore be recognised as a rapid charger. The charging
software is able to charge the battery with an input current within the range of
350-600mA. If the Charge-Fet is switched off, then no charging current will flow into the
battery (exception is trickle charging, see below).
For controlling the charging process it is necessary to measure the ambient (phone)
temperature and the battery voltage. The temperature sensor will be an NTC resistor
with a nominal resistance of 10kΩ at 25°C. The determination of the temperature is
achieved via a voltage measurement on a voltage divider in which one component is
the NTC. The NTC for the ambient temperature will be in the phone on the main
component group.
Recognition of the Battery Type
The battery code will be an resistor with a resistance of 8.2kΩ up to 56kΩ depending
on the manufacturer:
8.2kΩ corresponds to Panasonic
15kΩ corresponds to NEC
27kΩ corresponds to Sanyo
56kΩ not allocated
If no resistance is recognised, then the battery will not be charged.
Charging Characteristic of Lithium-Ion Cells
Li-Ion batteries are charged with a U/I characteristic, i.e. the charging current is regulated
in relation to the battery voltage until a minimal charging current has been achieved. The
maximum charging current is approx. 600mA, minimum about 100mA. The battery
voltage may not exceeds 4.2V ±50mV. The temperature range in which charging of the
phone may be started ranges from 5...40°C, and the temperature at which charging
takes place is from 0...45°C. Outside this range no charging takes place, the battery only
supplies current. Above 50°C the battery no longer supplies any current.
Trickle Charging
The power supply ASIC is able to charge the battery at voltages below 3.2V without any
support from the charge SW. The current will by measured by a shunt resistance and
linearly regulated inside the ASIC by means of the external FET driven in it´s active
region of the transfer characteristic as a typical linear pass element. The current level
during trickle charge for voltages <2.8V is in a range of 20-50mA and in a range of
50-100mA for voltages up to 3.75V. The maximum trickle time is 1 hour.
Matching up
In order to guarantee a correct working of the charge control, the measurement
hardware in the phone must be matched up. The matching up is done by means of a
self-test.
Restrictions
• A battery which has completely run down can not be re-charged quickly because
the battery voltage is less than 3.0V and the logics which implements the charge
control cannot be operated at this low voltage level. In this case the battery is
recharged via trickle-charging. However, the charging symbol cannot be shown in
the display because at this time logic supply voltages are not operating. The
charging time for this trickle-charging (until the battery can be fast-charged from
then on) is in the range of 1 hours. If, within this time, a voltage of 3.2V is
exceeded, then the ASIC switches on the mobile and charging continues in the
Charge-Only Mode. In some circumstances it can happen that after tricklecharging and the usually initiated switch-on procedure of the mobile, the supply
voltage collapses so much that the mobile phone switches off again. In this case
trickle charging starts again with a now raised threshhold voltage of 3.75V instead
of 3.2V, at maximum for 20 minutes.
• A phone with a fully charged Li-Ion battery cannot be supplied in the standby or
talk modus in the beginning because any input current would cause an
increase in the battery voltage above the maximum permissible value. If,
through using the phone, the battery has been run down to the tune of about
95% (estimated value), it can be supplied with current normally and the battery
can be re-charged.
• The phone cannot be operated without a battery.
• The phone would be destroyed if the battery were wrongly poled:
⇒ design-wise it is impossible to wrongly pole the phone. This is
prevented
by
mechanical
means.
⇒ electrically, a correctly poled battery is presumed, i.e. correct poling
must be guaranteed by suitable QA measures at the supplier
• If an unsuitable charger is connected, the mobile phone can be destroyed:
⇒ a charger voltage >15V can destroy resistances or capacitors in the current
supply
⇒ a charger voltage >20V can destroy the switch transistor in the current
supply.
If, in so doing, the transistor fails, then the overvoltage switch-off in the ASIC will
cease to function and the ASIC will be destroyed. Then the battery safety switch
will come into play. In the case of voltages smaller than 15V and an inoperative
current restriction, the battery can be permanently damaged. A protection against
grossly negligent use by the customer (e.g. direct connection of the charge
contact to the electricity supply in a motor car) is not foreseen. Customer safety
will not be affected by this restriction.

If the temperature is too high or too low, there is a high probability
that the battery is not charged. To enable the charging process again,
battery and phone needs to cools down or warm up. Battery
replacement is not required.
Avoid shorting the battery terminals.
Charging
The battery can be charged when it is inserted into the phone. The charging process is
completely controlled by the mobile. Charging can be done with any of the following accessory:
1.
2.
3.
4.
Rapid charger
Travel charger
Car charger
Desktop charger
Deep Discharge
In case of a deeply discharged battery, the phone can not be turned on and the normal
charging process can not be started.
In this case, charging the battery is divided into two different steps, which have to be run
subsequently:
a) Trickle charge
Trickle charge mode is automatically started if the battery voltage is below a certain
value when the charger is connected to the mobile. This mode is not terminated
automatically but has to be terminated by disconnecting the charger.
Trickle charge mode has to last minimum until the battery voltage has exceeded a
certain level. During trickle charge the charging symbol will not be visible and the
telephone can not be turned on. This is because the battery voltage is too low to
operate the telephone
Action:
Insert battery into handset and connect travel charger to the telephone. Wait for
appr. 1 hour, then disconnect and reconnect charger. If the battery voltage is high
enough again, the charging symbol will come up.
If the battery is discharged very deeply, the symbol may not come up and the trickle
charge time possibly has to be extended up to 24 hours.
b) Normal charge
When the battery voltage is above the a.m. value (e.g. by trickle charge) the mobile
will start the normal charging mode and show a charging symbol in the display.
Action:
Connect charger to the telephone.
The charging symbol will come up as an indication that the normal charging process
has been started by the mobile.
Dis-assembling the S45/ME45
A case opener is needed to disengage the latch of the S45/ME45 casing. This case opener
is exactly the same as the P35 Series.
