Drive Test Engineer/RF Engineer

§Means collecting data on vehicle movement. Its variation has also intuitive: Walk Test, i.e., collect data by walking areas of interest.

      a) Coverage area

      b) Coverage –Indoor & outdoor

      c) Speech Quality

      d) Interference  

      e) Call drops in the network

The main types of Drive Test are :

§Performance Analysis

§Benchmarking/Comparative Drive Test

§SCFT(Single Cell Functionality Test))

§Cluster Drive Test

   We will discuss this topics in detail later.

There are many drive test tools in market which is used by us

 for Drive Test.

 Drive Test Software tools are used by us:

§TEMS(8.0.3,9,10,11,12)NEMO,PROBE,AGILENT

§DONGLE (Related tools)

§ MOBILE ( W995 FOR TEMS,U 120E FOR PROBE ETC)

§TESTING SIM OF OPERATOR

§GPS 72,70 OR MOUSE GPS

§COMPASS

§MEASURING TAPE

§TILT METER

§USB HUB

§INVERTER

§CAB

 Note:-For connecting of Mobile from Laptop we use Data Cable & For Connecting Hand GPS(e.g-GPS-72,70) we use baffo cable.

ANTENNA:

An antenna (or aerial) is an electrical device which converts electric power into radio waves and vice versa

§It is usually used with a radio transmitter or radio receiver. In transmission, a radio transmitter supplies an oscillating radio frequency electric current to the antenna's terminals, and the antenna radiates the energy from the current as electromagnetic waves(radio waves)

§In the Telecommunication mainly we use Directional Antenna ,Microwave Antenna & Omni directional Antenna

§Antennas form a essential part of any radio communication system

§Antenna is that part of a transmitting or receiving system which is designed to radiate or to receive electromagnetic waves

§An antenna can also be viewed as a transitional structure between free-space and a transmission line (such as a coaxial line)

§An important property of an antenna is the ability to focus and shape the radiated power in space e.g.: it enhances the power in some wanted directions and suppresses the power in other directions

§Many different types and mechanical forms of antennas exist

§Each type is specifically designed for special purposes

OMNI DIRECTONAL ANTENNA:

These antennas are mostly used in rural areas.

–In all horizontal direction these antennas radiate with equal power.

–In the vertical plane these antennas radiate uniformly across all azimuth angles and have a main beam with upper and lower side lobes

Directional antenna:

§These antennas are mostly used in mobile cellular systems to get higher gain compared to omni directional antenna and to minimise interference effects in the network.

§In the vertical plane these antennas radiate uniformly across all azimuth angles and have a main beam with upper and lower side lobes.

§In these type of antennas, the radiation is directed at a specific angle instead of uniformly across all azimuth angles in case of omni antennas.

MAPINFO:

MapInfo Professional is a powerful Microsoft® Windows®-based mapping and geographic analysis application from the experts in location intelligence. Designed to easily visualize the relationships between data and geography, MapInfo Professional helps business analysts, planners, GIS professionals – even non-GIS users – gain new insights into their markets, share information-rich maps and graphs and improve strategic decision-making.

To launch MapInfo:

 Choose Start > Programs > MapInfo >MapInfo Professional 6.5 or simply click on the short cut on your desktop if one is created.

  For MapInfo preparation, you need to prepare your table in Excel spreadsheet (see Fig. 1) which should include the following: Site ID and Co-ordinates (Longitude and Latitude).
