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.

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.

• 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

• 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.

• There are two types of software used for optimization.A. TEMS Investigation

• B. Mapinfo Professional

• 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.

• 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.

1. Database Parameter Changes

• Many problems can be solved by changing some database parameters.•  Some of the common changes are

A. Handover parameters and thresholdsB. Maximum transmit power of BTSC. Paging parametersD. SDCCH Parameters

2. Antenna Optimization • This includes changing of antenna tilts, orientations, positions.• Sometimes the antenna may also be changed.

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.

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)
