ABSTRACT
The inspiration for our project is got from newspapers and issues
which are happening in our routine life. Nowadays stealing of ATM is too much
increased so due to that we are just trying to find out solution for it. At some ATM
centers there is no availability of security man, due to it some circumferences get
chance at there. Police investigation exposed that nevertheless the bank had
employed guards for round-the-clock duty, the night time guards in no way turned
up. Besides, the police say, rather than setting up or fixing the ATM device to the
ground, the financial institution had kept it on a desk like a TV arranged, creating
it much easier for that robbers. At present thieves are not just stealing the rupees
from ATM but they take away the whole cash box so because of it the security of
ATMs failed to stop them, so we want to find out how we can make that cash box
safe as much as possible and also will apply some security systems if we will get
that something going wrong there. Nowadays money is the important thing for all
the human being so that protection of it is also very important. Concentrating just
on these we have choose this project.

Introduction
This project includes GSM based messaging and tracking of ATM during theft.
1.1. PROBLEM FORMULATION:
ATM theft, it appears, is this recession’s hottest crime. There were more than 100 instances
of teller machine robberies in India alone in 2010. The thieves have snatched or attempted
to make off with ATMs 28 times in the past year. That’s up from 2 cases of the crime in the
year before. In Atlanta, which has also seen a spike in ATM crime, as many as 35 machines
have disappeared this year. As this is very big problem of safety of government money.
So, we have decided to improve our present security system. In this security system GSM
is used to protect ATM.

1.2. SUBJECT DEFINITION:
It is an electronic banking outlet, which allows customers to complete basic transactions
without the aid of a branch representative or teller.
An Automated Teller Machine (ATM) is a safety-critical and real-time system that is highly
complicated design in and implementation. This paper presents the formal design,
specification, and modeling of the ATM system using a denotation mathematics known as
Real-Time Process Algebra (RTPA).
Using an ATM, customers can access their bank accounts in order to make cash withdrawals,
debit card cash advances, and check their account balances as well as purchase prepaid cell
phone credit.
If the currency being withdrawn from the ATM is different from that which the bank account
is denominated in, the money will be converted at an official wholesale exchange rate.
Thus, ATMs often provide one of the best possible official exchange rates for foreign
travelers, and are also widely used for this purpose.
On most modern ATMs, the customer is identified by inserting a plastic ATM card with a
magnetic stripe or a plastic smart card with a chip that contains a unique card number and
some security information such as an expiration date or CVVC (CVV).
Authentication is provided by the customer entering a personal identification number (PIN).
The newest ATM at Royal Bank of Scotland operates without a card to withdraw cash up to
£100. The customers should register first their mobile phone number and bank will give a
six-digit code to enter into ATM to withdraw the cash.

1.3. BRIEF HISTORY OF PROJECT :
Still now many of theft case had been found in all over Gujarat. A minimum of six ATMs
have been stolen throughout Gujarat and there were attempts to carry two a lot more in a
daring robbery development noted considering the fact that February this calendar year.
At the same time as the police battle to crack these scenarios, the State Bank of India has
dropped above Rs forty three lakh in back-to-back ATM lifting scenarios– the 1st in Bharuch
on 2 nd April, then Ahmedabad on next day– prompting the bank to act urgently and network
together with the police to protected them.
The most significant robbery was reported in Bharuch on 2 nd April, when an SBI ATM that
contains Rs 21.eighty three lakh was lifted. The robbers ended up caught on camera.
The 2nd theft was noted in Axis Bank at Koyali, wherever the robbers first disconnected
CCTV cameras and after that lifted the ATM.
Perhaps inspired by a fast & furious Hollywood flick, robbers stole a cash-laden Automated
Teller Machine (ATM) from an SBI ATM booth in Maninagar. The heist has made the
robbers richer by Rs21 lakh, not to forget an ATM worth Rs2.80 lakh where they can keep
all this money safely.
Dhanjibhai Rathore, branch manager with SBI, Maninagar, has filed a complaint in this
regard with Maninagar police station that has commenced investigations in the matter.
The entire matter came to light at when locals in the area noticed something amiss at the
ATM booth in Kalgi Apartments near Jayhind Char Rasta. Investigations revealed that the
robbery took place between 3am and 3.30am. The ATM that was taken away was not fixed to
the ground, which is the norm.
They cut off electricity supply to the machines in the ATM booth, which logged them off
their nodal point at Mumbai. A CCTV camera was also disabled but another one remained
on. We are trying to extract footage,
15

The machines in the booth were refilled with Rs30 lakh Cops believe that robbers knew of
this refill and set their targets accordingly. Moreover, there were no security personnel or
mandatory GPS system at the booth, which made work easier for the thieves.
Vadodara noticed back-to-back lifting of three ATMs in March by you, other than a fourth
attempt that failed. While in the first incident here, the intruders lifted the ATM of Union
Financial institution of India in conjunction with the CCTV cameras at Bajwa. The guard,
who did not report for duty within the night of theft, was later arrested.
On March 18, there was a try to lift the ATM of Punjab National Lender in Vadodara. Once
the robbers failed this time, they broke the ATM device. They ended up later arrested.
In most cases, it was located the banks involved had not posted guards or set up cameras. In
certain instances, cameras inside of the ATMs had been non-functional.
CMS employee Rahul, along with his friend stole money from ATM Machine of Punjab
National Bank by hacking its password. The CMS employees know the password of ATM
machines as they transfer money in the machine. Both stole 9 lakh rupees from Vaghodiya-
Dabhoi Ring Road. But they were caught by Crime Branch.
After stealing the money they broke the ATM machine to mislead the police. But during the
investigation Crime Branch learnt that the money is looted by opening the machine with
password. Hence they nabbed the accused.
16

1.4. SURVEY FOR PROJECT:
Early ATM security focused on making the ATMs invulnerable to physical attack; they were
effectively safes with dispenser mechanisms. A number of attacks on ATMs resulted, with
thieves attempting to steal entire ATMs by ram-raiding.
Since late 1990s, criminal groups operating in Japan improved ram-raiding by stealing and
using a truck loaded with a heavy construction machinery to effectively demolish or uproot
an entire ATM and any housing to steal its cash.
Another attack method, Plofkraak, is to seal all openings of the ATM with silicone and fill
the vault with a combustible gas or to place an explosive inside, attached, or near the ATM.
This gas or explosive is ignited and the vault is opened or distorted by the force of the
resulting explosion and the criminals can break in.
This type of attacks can be prevented by a number of gas explosion prevention devices also
known as gas suppression system.
These systems use explosive gas detection sensor to detect explosive gas and to neutralize it
by releasing a special explosion suppression chemical which changes the composition of the
explosive gas and renders it ineffective.
Several attacks in the UK (at least one of which was successful) have emulated the traditional
WW2 escape from POW camps by digging a concealed tunnel under the ATM and cutting
through the reinforced base to remove the money.
Modern ATM physical security, per other modern money-handling security, concentrates on
denying the use of the money inside the machine to a thief, by using different types
of Intelligent Banknote Neutralization Systems.
A common method is to simply rob the staff filling the machine with money. To avoid this,
the schedule for filling them is kept secret, varying and random. The money is often kept in
cassettes, which will dye the money if incorrectly opened.

Chapter -2
What is an ATM?
2.1 ATM (AUTOMATED TELLER MACHINE):
An automated teller machine or automatic teller machine (ATM), also known as an
automated banking machine in Canada, and a Cash point, cash machine or sometimes a hole
in the wall in British English, is a computerized telecommunications device that provides the
clients of a financial institution with access to financial transactions in a public space without
the need for a cashier, human clerk or bank teller.
ATMs are known by various other names including ATM machine, automated banking
machine, and various regional variants derived from trademarks on ATM systems held by
particular banks.
On most modern ATMs, the customer is identified by inserting a plastic ATM card with a
magnetic stripe or a plastic smart card with a chip that contains a unique card number and
some security information such as an expiration date or CVVC (CVV). Authentication is
provided by the customer entering a personal identification number (PIN).
The newest ATM at Royal Bank of Scotland operates without a card to withdraw cash up to
£100. The customers should registered first their mobile phone number and bank will give a
six-digit code to enter into ATM to withdraw the cash
Using an ATM, customers can access their bank accounts in order to make cash withdrawals,
debit card cash advances, and check their account balances as well as purchase prepaid cell
phone credit.
If the currency being withdrawn from the ATM is different from that which the bank account
is denominated in, the money will be converted at an official wholesale exchange rate.
Thus, ATMs often provide one of the best possible official exchange rates for foreign
travelers, and are also widely used for this purpose.

Types of ATM
To access the advanced features of the complex units, you will usually need to be a member
of the bank that operates the machine.
22

2.3 Conceptual model of ATM:
An ATM system is a real-time front terminal of automatic teller services with the support of a
central bank server and a centralized account database.
This paper models an ATM that provides money withdraw and account balance management
services.
The architecture of the ATM system, as shown in Fig., encompasses an ATM processor, a
system clock, a remote account database, and a set of peripheral devices such as the card
reader, monitor, keypad, bills storage, and bills disburser.
Figure: 2.3
Conceptual model of ATM
23

An ATM is typically made up of the following devices:
‣ CPU : To control the user interface and transaction devices
‣ Magnetic Chip card reader: To identify the customer
‣ PIN Pad: Similar in layout to a Touch tone or Calculator keypad, often manufactured as
part of a secure enclosure.
‣ Display: Used by the customer for performing the transaction
‣ Function key buttons: Usually close to the display
‣ Touch screen: Used to select the various aspects of the transaction
‣ Record Printer: To provide the customer with a record of their transaction
‣ Vault: To store the parts of the machinery requiring restricted access
‣ Housing: For aesthetics and to attach signage to
Due to heavier computing demands and the falling price of Personal Computer-like
architectures, ATMs have moved away from custom hardware architectures using
microcontrollers and/or application-specific integrated circuits to adopting the hardware
architecture of a Personal Computer, such as, USB connections for peripherals, Ethernet and
IP communications, and use personal computer operating systems.
Although it is undoubtedly cheaper to use commercial off-the-shelf hardware, it does make
ATMs potentially vulnerable to the same sort of problems exhibited by conventional
Personal Computers.
The vault of an ATM is within the footprint of the device itself and is where items of value
are kept. Scrip cash dispensers do not incorporate a vault.
24

2.4 MECHANISMS FOUND INSIDE THE VAULT :
‣ Dispensing mechanism: To provide cash or other items of value.
‣ Deposit mechanism including a Check Processing Module and Bulk Note Acceptor :
To allow the customer to make deposits
‣ Security sensors : Magnetic, Thermal, Seismic, gas
‣ Locks: to ensure controlled access to the contents of the vault
‣ Journaling systems(many are electronic): A sealed flash memory device based on inhouse
standards
‣ Solid-state device: An actual printer, which accrues all records of activity including
access timestamps, number of notes dispensed, etc. This is considered sensitive data and
is secured in similar fashion to the cash as it is a similar liable.
25

2.5 PARTS OF ATM:
Figure: 2.4
Basic parts of ATM
26

An ATM has two input devices:
1. Card reader: The card reader captures the account information stored on the magnetic
stripe on the back of an ATM/debit or credit card. The host processor uses this
information to route the transaction to the cardholder's bank.
2. Keypad: The keypad lets the cardholder tell the bank what kind of transaction is required
(cash withdrawal, balance inquiry, etc.) and for what amount. Also, the bank requires the
cardholder's personal identification number (PIN) for verification. Federal law requires
that the PIN block be sent to the host processor in encrypted form.
An ATM has four output devices:
1. Speaker: The speaker provides the cardholder with auditory feedback when a key is
pressed.
2. Display screen: The display screen prompts the cardholder through each step of the
transaction process. Leased-line machines commonly use a monochrome or color CRT
(cathode ray tube) display. Dial-up machines commonly use a monochrome or color
LCD.
3. Receipt printer: The receipt printer provides the cardholder with a paper receipt of the
transaction.
4. Cash dispenser: The heart of an ATM is the safe and cash-dispensing mechanism. The
entire bottom portion of most small ATMs is a safe that contains the cash.
27

2.6 TRANSACTION SYSTEM
The conceptual model of an ATM system is used to be described by a Finite State Machine
(FSM), which adopts a set of states and a set of state transition functions modeled by a
transition diagram or a transition table to describe the basic behaviors of the ATM system.
The top level behaviors of ATM can be modeled in a transition diagram as shown in Fig.
Given below.

Securities
Security, as it relates to ATMs, has several dimensions. ATMs also provide a practical
demonstration of a number of security systems and concepts operating together and how various
security concerns are dealt with. Early ATM security focused on making the ATMs invulnerable
to physical attack; they were effectively safes with dispenser mechanisms. A number of attacks
on ATMs resulted, with thieves attempting to steal entire ATMs by ram-raiding.
3.1 HOW THEFT ATTACK ON THE MACHINE:
1. Ram-raiding is a variation on burglary in which a van, SUV, car, or other heavy vehicle
is driven through the windows or doors of a closed shop, usually a department store or
jewelers shop, to allow the perpetrators to loot it. Since late 1990s, criminal groups
operating in Japan improved ram-raiding by stealing and using a truck loaded with a
heavy construction machinery to effectively demolish or uproot an entire ATM and any
housing to steal its cash.
2. ATM burglary: An ATM burglary is when an ATM is broken into to steal its cash. The
attack takes place on site and may be a traditional “safe breaking” method or perhaps as
violent as explosive attack using gas or accelerants.
3. ATM Replenishment Attack Where directly employed staff, merchant or CIT courier are
attacked by criminals in the process of replenishing or dealing with cassettes within the
machine. Attacks usually take place when the ATM safe is open to receive / remove
cassettes, or when staff are transporting moneys through unsecured areas. These attacks
usually place personnel under considerable duress or physical thread.Plofkraak is used to
seal all openings of the ATM with silicone and fill the vault with a combustible gas or to
place an explosive inside, attached, or near the ATM. This gas or explosive is ignited and
the vault is opened or distorted by the force of the resulting explosion and the criminals
can break in.
4. A common method is to simply rob the staff filling the machine with money.
29

3.2 PREVENTIONS:
1. This type of attacks can be prevented by a number of gas explosion prevention devices
also known as gas suppression system. These systems use explosive gas detection sensor
to detect explosive gas and to neutralize it by releasing a special explosion suppression
chemical which changes the composition of the explosive gas and renders it ineffective.
2. Modern ATM physical security, per other modern money-handling security, concentrates
on denying the use of the money inside the machine to a thief, by using different types of
Intelligent Banknote Neutralization Systems.
3. To avoid rob the staff filling the machine, the schedule for filling them is kept secret,
varying and random. The money is often kept in cassettes, which will dye the money if
incorrectly opened.
4. ATM Should be Properly attached with Ground.
5. The Alert alarm should be improved such that it makes an alert to local police and local
authority within time of tampered.
6. A high resolution digital camera should be such placed that it is activated on tampering of
ATM and take a picture automatically after each seconds.
7. Theft try to open the ATM so after that a Battery attached Sock jerk can be develop with
the Body of ATM.
8. Cash box should be such design that it will auto lock to each other from internally
9. Activation of Security alerts to be sent to all Station as per area.
30

3.3 SECURITY DEVICES:
3.3.1 SECURITY SENSORS:
‣ Seismic sensor:
The Seismic, Heat and Light detector is suitable for the detection of most known
attacks on metal & concrete objects. It is used as safe and ATM sensor, also as vault
and safe protection device.
‣ Gas sensor:
The Gas sensor is the ultimate solution against gas attacks. As soon as the specially
constructed sensors detect an explosive gas, the intelligent controller releases a special
explosion suppression chemical which changes the make-up of the explosive gas that
renders it ineffective. Thus it prevents structural damage to the ATM and to your
premises.
‣ Temperature sensors:
These sensors translate the temperature into a reference voltage, resistance or current,
which is then measured and processed and a numerical temperature value is computed.
‣ Pressure sensors:
These sensors translate the increase or decrease pressure into reference voltage.
‣ Vibration sensors:
The robbers have the Brake or hole hardly into the ATM devices, for a certain limit of
vibration is not sensing, but beyond the certain limit it sensing.
31

3.3.2CCTV CAMERAES:
Closed-circuit television (CCTV) is the use of video cameras to transmit a signal to a
specific place, on a limited set of monitor. CCTV equipment may be used to observe
parts of a process from a central control room.
Figure: 3.2
CCTV cameras
3.4 RECENTLY LAUNCHED SECURITY SYSTEM:
A GSM based system Micro ABB (ATM black box) monitors and protects the ATM centre
from instances of theft and robbery. With the rising numbers of ATM attacks and ATM
based fraud in the country, securing the popular banking channel is fast becoming a priority
for banks.
Some of the most common techniques used by ATM thieves and robbers include ram raids,
explosive attacks, and cutting using rotary saw and blow torch. Robberies sometimes also
occur when ATMs are being replenished or serviced.
32

Micro Technologies (India) Ltd. launched an innovative product for the banking sector-
Micro ABB on 6th January 2012 during the ‘Cop-Community Connect’ seminar. Micro
Technologies launched Micro ABB at the event.
According to industry estimates, over 2.3 million ATMs around the world of which 72,000
are reported to be in India. However, thefts at the ATM centers are one of the serious issues.
ATMs are an important part of commerce throughout India and provide a valuable service to
customers. With the growth of the use of ATMs there has also been a dramatic increase in
ATM attacks and fraud.
Figure: 3.3
Micro ATM black box
ATM physical attacks are carried out with the intention of gaining access to the cash within
the ATM safe or the ATM security enclosure. Some of the most common methods include
ram raids, explosive attacks (gas and non-gas) and cutting (e.g. rotary saw, blow torch,
thermal lance, diamond drill).
33

Robbery can also occur when ATMs are being replenished or serviced. Staffs are either held
up as they are carrying money to or from an ATM, or when the ATM safe is open and cash
cassettes replaced. It is a unique, state-of-art and advanced security systems developed for
the Banking Sector, securing ATM machines and providing Energy Efficient Technology
for ATM Centers.
Micro ABB a GSM based real time security system that monitors and controls ATM centre
and problems stated above. It sends alert SMS to the registered user in case of intrusion
occurred due to fire, vibration, door open and motion.
Micro ABB comes with life support feature like Wireless Panic Switch, which can be used
by the guard in case of emergency. It is also integrated with the biometric based attendance
system wherein the guard’s attendance will be recorded to minimize the time theft.
Micro Technologies has received test certification for maintaining international standard for
its innovative product Micro ABB. Besides, Micro ABB has been successfully installed in
ATMs of many international banks that are showing satisfactory results
3.5 FAILURE OF RECENT SECURITY SYSTEMS:
‣ Need of guards: all the ATM centers required security guards for prevention of stealing.
But in many cases those guards go for outing or get sleep, which make easy way for the
thieves for their robbery. And there is no possibility to provide guards in every center and
also banks have to pay for them.
‣ High cost: security system in present is much costly and can’t implement in all branches.
And the payment for the guard again increases it.
‣ No tracking system: In present security system the security is only limited to the
cashbox. No security when that cash box move away from its place. There is also no
tracking system if the whole cash box is carried out.

4.1.1 Sensors:
Seismic sensors are used to senses movement in the machine, and others are used to on off
the camera.
The Seismic, Heat and Light detector is suitable for the Detection of most known attacks
on metal & concrete objects used as safe and ATM Sensor, also as vault and safe protection
device Combined Seismic sensor for high Security sites.
Three Detection technologies: Seismic (Bimorph sensor), light and heat. It Provide full
protection to Teller Machines, Cash Dispensers, Safe Protection & Banks Safes Deposit.
The seismic detectors are designed to detect attempts to break into vaults, safes, night
deposit boxes, automatic teller machines (ATMs) and other reinforced physical areas such
as data storage's and filing cabinets.

The sensor is a next generation development based on proven high technology electronic
processing with excellent secure detection without false alarms.
Not only with a new look but also designed for the highest security with full-scale tamper
protection and two possibilities of testing.
4.1.2 Control and Monitoring By Alarms:
Alarm Receiving Centre (ARC): The alarm system should be monitored from an ARC 24
hours daily. The ARC, which should conform to ISO and local police standards, should
automatically generate an alarm signal if the telephone line fails or is cut. In the event that
an alarm signal is received, the ARC should respond according to its standard operating
procedures.
Response: In the event of an alarm the ARC should be able to request a response from a
third party to visit the ATM within an agreed (ideally contractually binding) time period.
System/Line Failure: In the event that the alarm detection system fails to operate for any
reason, or there is a fault in the telephone line, the ATM should be cleared of all cash until
such a time as the system is operation and has been tested
4.1.3 Microcontroller:
It is a chip having inbuilt computer processor to minimize need of external circuits.
Figure: 4.3
89C51 Microcontroller
37

A microcontroller is a small computer on a single integrated circuit containing a processor
core, memory, and programmable input/output peripherals.
Program memory in the form of NOR flash or OTP ROM is also often included on chip, as
well as a typically small amount of RAM.
Microcontrollers are designed for embedded applications, in contrast to the
microprocessors used in personal computers or other general purpose applications.
4.1.4 GSM message sending:
A GSM modem is a wireless modem that works with a GSM wireless network. A wireless
modem behaves like a dial-up modem.
The main difference between them is that a dial-up modem sends and receives data through
a fixed telephone line while a wireless modem sends and receives data through radio
waves.
AT commands are used in GSM to send the message.
Besides sending text messages, SMS can also be used to send small data messages. A
single SMS message can contain up to 140 bytes of user data. These messages can be used
for custom applications, telemetry and over the air programming of the phone or SIM card.
Messages such as ringtones, operator logos and WAP Push messages are also encoded as
data messages.

4.1.5 Interfacing of GSM with microcontroller:
Instead of sending commands from the HyperTerminal, AT commands are sent to the GSM
module by the microcontroller itself. In this case, the receive (Rx) and transmit (Tx) pin of
the GSM module’s RS232 port are connected to the transmit (Tx) and receive (Rx) pin
of AT89C51’s serial port, respectively. This eliminated the role of computer and just the
controller’s circuit provides a complete user interface for the module.
Figure: 4.4
Block diagram of interfacing of GSM with microcontroller
The controller is programmed to send a fixed command ‘AT’ to the module.
The command AT is used to check the communication with module. It returns a result code
OK if the module and the controller are connected properly.
If either of the module or SIM is not working, it returns a result code ERROR.

Circuit diagram of interfacing of GSM with microcontroller
4.1.6 Security Activation:
After receiving message, security system which includes alarm, automatic door locking,
cameras get activated. For ATM machines it is best to use two kinds of cameras.
The first camera should be an obvious camera that is set up on top or very close to the
ATM machine. The second camera would be a hidden camera installed inside the ATM
machine itself to allow it to capture the facial features of the customer. Those two cameras
severe different but complementary purpos.
To start with, the obvious camera can greatly assist in deterring away any type of crime or
suspicious activity near the ATM machine. On top of that, it would help the viewer to
40

Conceive what is happening around the ATM machine and will present the bigger picture
in a better view compared to the small hidden camera.
On the other hand, the hidden camera will do a great job at identifying potential hackers
and thieves who try to break into the machine or try to force others into giving them their
money using the ATM machine.
Even though those two cameras do different things, their combined footage tell a more
complete story and tend to make police investigations go a lot smother.
4.1.7 Location finding:
If robbers try to take the whole ATM box, the position of ATM is unknown so we can find
out the position of machine by using tracking system by improved vehicle tracker.
4.1.8 Final Action:
When security gets activated, message is received by the authorized person and final action
is taken by police and patrolling staff to catch the thieves red handed. The position of ATM
can find out and can secure our government property.

4.2GSM MODULE:
4.2.1 Introduction to GSM:
GSM (Global System for Mobile Communications) is world's most famous Mobile
platform. Mobile phones with SIM cards use GSM technology to help you communicate
with your family, friends and business associates.
GSM(Global System for Mobile Communications, originally Groupe Special Mobile), is a
standard set developed by the European Telecommunications Standards Institute (ETSI) to
describe protocols for second generation (2G) digital cellular networks used by mobile
phone.
4.2.2 GSM unit:
The GSM Modem supports popular "AT" command set so that users can develop
applications quickly. The product has SIM card holder to which activated SIM card is
inserted for normal use. The power to this unit can be given from UPS to provide
uninterrupted operation. This product provides great feasibility for devices in remote
location to stay connected which otherwise would not have been possible where telephone
line do not exist.

4.2.4 GSM frequency bands:
GSM networks operate in a number of different carrier frequency ranges (separated into
GSM frequency ranges for 2G and UMTS frequency bands for 3G), with most 2G GSM
networks operating in the 900 MHz or 1800 MHz bands.
Where these bands were already allocated, the 850 MHz and 1900 MHz bands were used
instead (for example in Canada and the United States). In rare cases the 400 and 450 MHz
frequency bands are assigned in some countries because they were previously used for
first-generation systems.
Most 3G networks in Europe operate in the 2100 MHz frequency band.
Regardless of the frequency selected by an operator, it is divided into timeslots for
individual phones to use. This allows eight full-rate or sixteen half-rate speech channels per
radio frequency. These eight radio timeslots (or eight burst periods) are grouped into a
TDMA frame.
Half rate channels use alternate frames in the same timeslot. The channel data rate for all 8
channels is 270.833 Kbit/s, and the frame duration is 4.615 ms.The transmission powers in
the handset is limited to a maximum of 2 watts in GSM 850/900 and 1 watt in GSM
1800/1900.

transactions from central servers. The main benefit is that central server can be
anywhere in the world.
3. Supply Chain Management:
With a central server in your head office with GSM capability, you can receive instant
transaction data from all your branch offices, warehouses and business associates with
nil downtime and low cost.
47

4.3 “AT” commands:
AT commands, also called Hayes AT commands, are based on the Hayes Modem de facto
standard, ATTENTION Commands for modems.
They are used to communicate with your modem. These commands modify your modem's
behavior or instruct the modem to do something specific, such as dialing a telephone number.
The "AT" refers to getting the Attention of your modem.
To send a command to modem, we need to start a terminal program such as Windows Hyper
Terminal .No matter which terminal program you use, it should be configured to communicate
with the COM port that your modem is attached to.
You then type commands in the Terminal window. The modem executes the command and
responds appropriately. One set of AT commands will identify your modem and version
information.
