RF OPTIMIZATION OF GSM COVERAGE AREA USING AGILENT TOOL

RF OPTIMIZATION OF GSM COVERAGE AREA USING AGILENT TOOLPresented byB.SAISIREESHA - 12G21A0420

OBJECTIVETo measure and maintain the quality of the network in GSM area using AGILENT TOOL.

Drive testing to gather radio frequency.

Analyze the network performance.

Proposed solutions to resolve issue or meet benchmark.

INTRODUCTIONGSM network consist of differentcells.For proper working of base station many parameters are consider.Before functioning the base station such as the coverage area of a cell depends on different factors,The transmitting power of the base station, Obstructing buildings in cells, Height of the base station and Location of base station.

LITERATURE SURVEYPROJECT TITLEAUTHOR NAMEYEAR OF PUBLICATIONWORK DONEPerformance analysis of GSM Network with intelligent underlay-overlay. Khalid Begain,Gergo Istvan Rozsa,Andras Pfening,Miklos Telek2002Implement the Intelligent scheme to increase Frequency reuse and Capacity of network.Radio Access Network Audit and optimization in GSM.Dr. M.Adeel Akram2010To improve process resulting in optimized network and improve Quality Of Service.PROBLEM DESCRIPTIONBlocked calls.Low throughput.Latency (or) Delay.Coverage holes.

Blocked calls

LOW THROUGHPUT

COVERAGE HOLESYOUR SITE HEREHigh sensitivity to interferenceRequires "secured" Frequency reuse pattern High isolation from interferencesA few Frequencies intensively reusedMACRO-CELL:antenna radiating above roofs---> Wide Coverage ( 35 km)MICRO-CELL:Antenna below the roofs---> small coveragePICO-CELL:Antenna inside building---> Very small coverage

EXTENDED-CELL:macro cell with system coverageextension ( 120 km) for coasts...CONCENTRIC-CELL:macro cell with system coveragelimitation inside another macroPROPOSED SYSTEMMaintaining the quality of the network using AGILENT TOOL.

Finding and correcting any existing problems after site implementation and integration.

Optimization will be continuous and iterative process of improving overall network quality.

Optimization can not reduce the performance of the rest of the network.

Area of interest is divided in smaller areas called clusters to make optimization and follow up processes easier to handle.

AGILENT TOOLWireless measurement tool is E6474A .

It is a software used to monitor the performance of the network in BSNL.

It is introduced by HP.

In south India AGILENT tool is used.
