Cellular Communication

Coverage Concept.

he cellular systems is made up of numerous transmitting and receiving sites, whose
individual coverage areas partially overlap. The concept of frequency re-use, same
frequency is used by several sites, allows a high traffic density in a wide area. Due to the

limited transmission range of the terminals, cellular systems are based on a large
number of base stations on the infrastructure side, scattered over the area to cover, with each
covering a fairly small geographical zone called cell. Cells are often represented by hexagons
(see figure 1.1.).

FIGURE 1.1 CELLULAR COVERAGE REPRESENTATION.

GSM Network Architecture.

GSM network can be broadly divided into three broad parts, namely:

1. Mobile Station(MS) carried by the subscriber,

2. Base Station Sub-system(BSS) which controls the radio link with the mobile station.

3. Mobile Switching Center(MSC) which performs the switching of calls between the mobile
users, and between mobile and fixed network users.

FIGURE 1.2 GSM ARCHITECTURE

Each mobile station is given a unique identity. As soon as the mobile phone is turned on, it
registers with the network and is authenticated; as such the network could always find the mobile
phone.
Larger amount of data is being exchanged to and from the following functional blocks in the MSC:

Visitor Location Register, VLR

Stores information about mobile subscribers that enter it coverage area, which is associated with
the geographical area where the mobile is currently roaming. When there is an incoming call for
the mobile, the HLR is interrogated about the present address of the VLR.

Home Location Register, HLR

A database that contains all data concerning the subscription of the mobile subscriber, i.e. their
access capabilities, subscribed services, and supplementary services. It also contains information
about the VLR that is handling the mobile station currently. When the mobile changes location,
the HLR is updated accordingly. It also provides the MSC with information about the MSC area
where the mobile is actually located to allow incoming calls to be routed immediately to the called
party.

Authentication Center, AUC

Stored information that is necessary to protect communication through the air interface against
any intrusions. The legitimacy of the subscriber is established through authentication and
ciphering, which protects the user information against unwanted disclosure.

Equipment Identity Register, EIR

An option the network operator can use to enforce security. With this feature the network can
identify defective or stolen mobile that may not be used in the network.

2

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 SIM card and can be changed by the
subscriber. PIN2 is required for additional functions available with a special SIM card (Consult the
operator for more information about the PIN 2).

A code (PUK) is provided for unlocking the SIM card if the SIM card is blocked

.

3

SIM Application Toolkit

This is a new GSM feature that has been integrated into the GSM standards in Release 96, with
further enhancements added as part of the Release 97 feature set. This feature came about
because of a desire by Network Operators to offer differentiated services, without the need for the
Mobile Manufacturers having to build different variant for different customers. The unique service
offered by the Operator is placed as an application on the SIM and that could work on any mobile
that supports the Toolkit feature.

There is a distinct set of commands between the mobile and the SIM specifically for the Toolkit
that allows the SIM Toolkit and the mobile to communicate independently of the GSM
communication between the SIM and the mobile. Henceforth, the SIM Application Toolkit and
GSM functionality on the SIM are separated logically. The Toolkit can interact directly with the
mobile itself and adding itself to the mobile menu.

Currently, Toolkit application on the SIM and its “other half” communicate by using the Short
Message Service(SMS). “Proactive SIM” is a mechanism whereby the SIM can initiate actions to
be taken by the mobile. These actions include:

· Display text from the SIM on the Mobile display

· Send short message

· Set up a voice call to a number held by the SIM

· Set up a data call to a number and bearer capabilities held by the SIM

· Send a Supplementary Service (SS) control or Unstructured Supplementary Services Data

(USSD) string

· Play a tone in the mobile’s ear piece or ringer

· Initiate a dialogue with the user

· Provide local information from the mobile to the SIM.

· Data download to the SIM from network

· Call control by the SIM.

SIM Applications Toolkit (SAT) allows the flexibility to update the SIM, to change the services and
download new services over the air. In the SAT specification, the short message service is a key
mechanism for personalizing the SIM in each user’s GSM phone. It is designed as a client-server
application. CL50 supports SAT Class 3 specification.

When active, the name of the service may appear in the menu, and there will be sub-menu if
more than one application is active. Figure 1.4 is the SAT icon.

FIGURE 1.4 SAT ICON

Extended GSM 900, E-GSM

This is a new standard that allows Network Operators to increase their capacity through an
extended frequency. The frequency range of E-GSM is as follows:

· Mobile Transmit: 880 – 915 MHz

· Mobile Receive: 925 – 960 MHz

CL50/8008 series is a GSM Phase 2 / Phase 2+ Dualband E-GSM / GSM 1800 mobile phone.

Wireless Application Protocol, WAP.

Wireless Application Protocol takes a client-server approach that uses the in-built micro-browser
to make a request, in wireless markup language (WML), for information or service. The request is
passed to a WAP Gateway, which then retrieves the information from a Internet server, in HTML
format, and translate it into WML. The requested information is then sent to from the WAP
Gateway to WAP client (mobile) using the available and most appropriate mobile network bearer
services.

Wireless Protocol Stack.

Wireless Application Environment (WAE)
Wireless Session Protocol (WSP)
Wireless Transaction Protocol (WTP)
Wireless Transport Layer Security (WTLS)
Wireless Datagram Protocol (WDP)
Bearers e.g. Data, SMS, USSD

TABLE 1..1 WAP PROTOCOL STACK

1. Wireless Application Environment

Defines the user interface on the phone. WAE contains the WML,WML script and the
wireless telephony application (WTA).

2. Wireless Session Protocol

Link the WAE to two session services – one connection oriented operating above the WTP
and a connectionless service operating above WDP.

3. Wireless Transaction Protocol

Runs on top of the datagram service and part of the standard suite of TCP/IP protocols, to
provide a simplified protocol suitable for low bandwidth mobile station.

4. Wireless Transport Layer Security

WTLS incorporates security features that are based upon the established Transport layer
Security (TLS) protocol standard, that include data integrity checks, privacy on the WAP
Gateway to client leg and authentication.

5. Wireless Datagram Protocol

Allows WAP to be bearer independent by adapting the transport layer of the under-laying
bearer. WDP presents a consistent data format to the higher layer on the WAP stack.

WAP Internet access via the CL50 is possible with the inclusion of Wireless Application Protocol
(WAP) browser 1.2.1.

Mechanical Concept

Please take note that the number(s) used here IS NOT the part

number, DO NOT used it in your spare parts purchase order.

Always refer to the SERVICE PART PRICE LIST

for your spare part order.

The mechanical concept of the CL50 as a clam shell is much different from other Siemens series
mobile phones.

CL50 can be divided into two main physical blocks, the display module and main function assy.
The display module is composed of internal and external LCD protected by LCD base and lens
with shielding effect. The display module will joint buzzer, receiver and top cover as LCD module
and the housing will damaged if striping the module down.

For the main function assy., there are 4 screws located on the base and 1 on the M/B.
Screwdriver (T5) and tweezers will be used as main tools to perform mechanical repair.

Inside, the CL50 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 flexible cable which is inserted into a plug-in
connector. In case they are defective electrically or mechanically it can be exchanged very
quickly. DC jack cover, volume key knob and key cover can be easily taken off as well. Speaker
also can be separated from base. Make sure the speaker springs are not dirty or damaged during
repair process.

The contact points of software upgrading and connector for external RF cable are located at the
back side of the mobile. As a consequence of this, there needs a extra jig which can put in the
battery or connect to power supply after modification to perform the download and test process.

The CL50 is a dual-band mobile operating on GSM900 and

GSM1800, the antenna is an integral part of the base.

TRANSCEIVER ( CX74017 )

The receive path implements a direct down-conversion architecture that eliminates the
need for Intermediate Frequency (IF) components. The CX74017 receiver consists of
three integrated Low Noise Amplifiers (LNAs), a quadrature demodulator, tunable
receiver baseband filters, and a DC-offset correction sequencer. In the transmit path, the
device consists of an In-phase and Quadrature (I/Q) modulator within a frequency
translation loop designed to perform frequency up-conversion with high output spectral
purity. This loop also contains a phase-frequency detector, charge pump, mixer,
programmable dividers, and high power transmit Voltage Controlled Oscillators (VCOs)
with no external tank required. Except for the loop filter, the frequency synthesizer
function, including a wideband VCO, is completely on-chip.The radio frequency gain
range of GSM=20dB, DCS/PCS=22dB and baseband gain range.

VOICEBAND BASEBAND CODEC ( AD6521 )

It contains complete codecs for the conversion of voiceband signals as well as D/A-converter to
control the radio subsystem and an auxiliary A/D- converter for system monitoring purposes. The
baseband codec is a complete low power, two channel, input/output port with signal conditioning.
The transmit path consists of a GMSK modulator and two high speed DACs with output
reconstruction filters together with a ramp DAC with on-chip RAM providing the power ramp
shape. The receive path consists of two high-resolution Sigma-Delta A/D converters which
include high performance digital filters for RF-channel selection.
The voiceband codec is a complete analog front-end, which can interface directly with a
microphone and speaker. For interfacing with hand-free or external car kits, separate input and
output channels are provided.
The auxiliary section consists of D/A converters for Automatic Frequency Control (AFC) and a
current DAC (IDAC) for battery charging applications. Additionally, an auxiliary A/D converter in
included, which can be used to monitor up to six analog signals.

The telephone support only 1.8V and 3V SIM card

For user with 5V SIM card, he needs to upgrade the SIM card

through his service provider/network operator

14

Power Supply Concept

The CL50 has two main power inputs:

1. Battery voltage (3.7V) connected at the battery contact

2. Charging voltage (5V) delivered by the different charger type(see Accessory List) via
DC jack at the bottom of the telephone.

Since the battery voltage is supplying the power supply ASIC, it is always needed to
operate the phone. You cannot switch on the handset if the battery voltage is not

present.

From the battery voltage, all other supply voltages are derived and controlled by the
power supply IC.

The RF power amplifier is directly connect to the battery, a bad battery with high internal
resistance can cause malfunction of the CL50 phone.

Charger(5V/400 mA)

Charging
Circuit

Power Amplifier

The IC generates the supply voltage to other as below:

SIM Card: 2.80-2.92 V/ 20mA
RTC: 2.40-2.50 V/10uA
Memory: 2.744-2.865V /60mA
Digital Core: 2.40-2.50 V/ 100mA
Analog: 2.40-2.50V/ 130mA

TCXO: 2.744-2.865V /60mA

The IC also checks the presence of the watchdog signal from the microprocessor and
provides the switching on functionality (ON_OFF button or Ignition signal).

Wrong polarity or battery voltage setting that exceed the +6.2V could

damage the phone.

15

Over-voltage Condition

· Battery voltage

If the supply voltage rises above 6.2V, the phone will switch off and it cannot be
switched on again before the voltage is lower than 6.2V.

If the supply voltage rises above 10V, the phone can be damaged.

· Charging Current

The charging current must not rise above 1A or a track fuse in the phone will blow. As
a result charging the battery will no longer by possible.

Be careful with NON-original SIEMENS accessories or chargers.

Make sure that the charging current is limited to value below 1A.

Battery – Charging

CL50 series uses a Li 600mAH battery pack as standard battery and the supplier is
“Sanyo”.

Contact points

16

Batt+ Batt_Temp GND

For CL50, BATT+ has a voltage level from +3.4V to 4.2V, and a BATT_TEMP contact is used for
detecting abnormal increase in temperature of the battery.

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.

Short Circuit Protection

For the Nickel Metal Hydride battery, a polyswitch in the battery pack protecting the battery from
short circuit and it should reset by itself after some time removing the short circuit.

For the Lithium Ion battery, it is short-circuit protected by an electronics fuse. The fuse will be
activated in case a too high current is drawn. This fuse will not reset automatically.

The resetting of the battery fuse can be done with either of the following procedures:

1. Insert the battery into the CL50 and then connect the rapid charger to the phone. Wait for
approximately 10 second, then the mobile can be turned on again.

2. Plug the battery separately into the desktop charger. The fuse is reset immediately.

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. Rapid charger

2. Travel charger

17

PHOTO 2.4 INSERT CHARGER

Please make sure the triangle mark faces down.

Deep Discharge Battery

In case of a deeply discharged battery, the voltage of the battery is too low to operate the
charging circuit and the display controller, the phone cannot be turned on and the normal
charging process cannot be started. No charging symbol is visible in the display.

In this case, charging the battery is divided into two different steps, which have to be run
subsequently:

a) Trickle charge for CL50 Phone

Trickle charge mode is automatically started if the battery voltage is below 3.0V when the
charger is connected to the mobile. The charging current in Trickle mode is appr. 10mA.

Action:

Insert battery into handset and connect travel charger to the telephone. The charging
symbol will not show in the display.

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. * Always
normal charge a new battery or a deep discharged battery for more then 12 hours before
first use.

Action:

Connect charger to the telephone (see section on Charging).

The charging symbol will come up as an indication that the normal charging process has been
started by the mobile.
