The document discusses optimization of Bharti Airtel's 3G network in India. It describes optimization as improving network efficiency and quality of service by maximizing available infrastructure. A team is assembled including managers, engineers, and drive testers to set parameters, check licenses, run scripts, and conduct drive testing both before and after optimization changes. MapInfo Professional and TEMS Investigation software are used to aid the optimization process. Common optimization strategies mentioned include database parameter changes, antenna optimization, frequency changes, neighbor modifications, and adding new cell sites.

2. Bharti Airtel Limited, a part of Bharti Enterprises, is India's leading
provider of telecommunications services. Bharti Airtel, formerly
known as Bharti Tele-Ventures Limited (BTVL) is India's largest
Telecom Business operator with more than 75 million subscribers It
also offers fixed line services and broadband services. It offers its
TELECOM services under the Airtel brand and is headed by Sunil
Mittal. The company also provides telephone services and Internet
access over DSL in 14 circles. The company complements its
mobile, broadband & telephone services with national and
international long distance services. The company also has a
submarine cable landing station at Chennai, which connects the
submarine cable connecting Chennai and Singapore.

4. Optimization is the process of improving the
operation of the network to better utilize
available infrastructure to provide customers
of the service the best possible quality of
service. The process maximizes the efficiency
and operability, of the existing installed
infrastructure.

5. • Optimization in itself is a complete department, So it cannot be
accomplished by a single person. It needs a Team work.
• 1. Senior Manager: Mr. Sanjeev Mahrolia
2. Senior Engineer: Mrs. Kitty Sharma
3. Trainee: Mr. Anurag Aggarwal
4. Drive Tester: Mr. Deepak, Mr. Manoj, Mr. Tushar, Mr.
Nishant, Mr. Amit

6. • Optimization is an invaluable element of service required to
maintain and improve the quality and capacity of a network.
• It is essential if an operator wants to implement changes to the
network to maintain the high quality of service levels expected by
subscribers in networks.
• Without optimization the network will degrade from the
commissioned state, due to the network changing radically as the
traffic on the system grows, and snapshot optimization will not keep
pace with these changes.
• Without optimization the system will suffer poor call quality, many
dropped calls due to interference and inaccurate parameters resulting
in poor handover performance.
• These together with other problems, have the same result,
Subscriber Dissatisfaction.

• CHECKING AND CORRECTING LICENCE PARAMETERS
A. HSDPA USERS
B. EUL USERS
C. TRANSMISSION POWER
D. TOTAL OUTPUT POWER

B. PRE DRIVE
C. POST DRIVE

8. • There are two types of software used for
optimization.
A. TEMS Investigation
• B. Mapinfo Professional

9. • MapInfo Professional is a powerful Microsoft Windows-based mapping application that enables business analysts
and GIS professionals to easily visualize the relationships between data and geography. With MapInfo Professional,
you can perform sophisticated and detailed data analysis by leveraging the power of location.
Features of MapInfo Professional to:
• 3D Viewing- 3D viewing allows for freehand tilt and rotations of your maps as well as for traditional panning and
zooming.
• Charts & Graphs- MapInfo Professional interactive graphs and charts including 3D, bubble, column, histogram,
surface, area, bar, line and pie scatter charts.
• Distance calculator-MapInfo Professional helps to determine the distance between multiple objects at once. It
calculates distances automatically among customers and offices based on join criteria.
• Synchronization utility- It helps simultaneously control navigation of multiple open map windows (all open map
windows pan and zoom to the same location if requested).
• Search and replace feature-It helps to automatically change a value with another value in multiple columns.
• Distance location- MapInfo Professional helps to find location of any city, district and town of any state.

11. • TEMS Investigation is an air interface test tool for real-time diagnostics. It lets
you monitor voice channels as well as data transfer over GPRS, EDGE,
Circuit-switched (CSD) or high-speed circuit-switched(HSCSD) connections.

12. 1. Database Parameter Changes
• Many problems can be solved by changing some database parameters.
• Some of the common changes are
A. Handover parameters and thresholds
B. Maximum transmit power of BTS
C. Paging parameters
D. SDCCH Parameters
2. Antenna Optimization
• This includes changing of antenna tilts, orientations, positions.
• Sometimes the antenna may also be changed.

13. 3. Frequency Changes
• Frequency changes help us to control the interference in the network.
• However one should be careful when doing these changes so that this changes
do not affect the other sites adversely.
• If there are a lot of changes it is advisable to change the whole frequency plan.
• A careful study of cell coverage area and server area helps in making those
changes.
4. Neighbor Addition And Deletion
• Many problems arise due to wrong neighbor definitions or missing neighbors.
• Neighbor definitions must be reviewed on a regular basis. Statistics and drive
tests provide good inputs for this purpose.

14. 5. Formation Of New Location Areas
• Sometimes to solve paging load problems it might be required
to for new location areas.
6. Addition of new cell sites
• Sometimes to solve coverage hole problems we need to add
more site (normally micro or pico cells)
