What is drive testing in Telecom Procedure of drive testing
Drive Test is conducted for checking coverage criteria of a cell site with RF drive test tool. The data collected by drive test tool as Log files is analyzed to evaluate various RF parameters of the network.
This way mobile phone companies can decide how to improve their network coverage in a certain geographical area.
Normally it is conducted in a car, with one driver and one or two drive testing engineers checking the data and navigating the driver to the right direction if necessary. These drive testing engineers first reach to the tower location and make physical optimization by inspecting issues like cable swapping, improper hardware, alarms, antenna tilting (machenical and electrical), antenna orientation.After field or physical optimization he starts drive testing by his vehicle. Drive testing engineer collects network data by making a lot of calls (short and long). The data collected includes data for serving cell as well as the neighbours.This data collected helps us to find and analyze the problems in the network.
Drive Test performance measurements are carried out for the following reasons:
Here i am suggesting some precautions for beginners in drive testing -

- Drive Route and Site Data for the sites to be driven is taken from customer
- Drive Test LOG File of the specified Drive Route / Site is saved and the same will be handed over to customer at the end of the day
- Drive Test Resource identify routine field optimization issues like cable swapping, missing neighbors etc., and rectify the same with the help of the customer.

Drive Test performance measurements are carried out for the following reasons:
- Test the network from the subscribers point of view
- Test the complete system, end to end
- Benchmark performance against competitor networks
- Test specific important routes and areas
- Test in-building coverage for specific buildings(Metro, Airport, office etc.) called walk test.
- Vehicle
- Drive test mobile phone (e.g Ericsson TEMS)
- Dongle (network inspection USB)
- External vehicle mounted GPS
- Laptop with drive test software and GPS connection capability and data cables, multi-connector port etc.
- TEMS Investigation
- Agilent E6474A
- Neptune
- CDMA Air Interface Tester (CAIT)
- TEMS DeskCat
- Actix Analyze
Here i am suggesting some precautions for beginners in drive testing -
- Before starting your drive test, Collect all your equipment like GPS, Dongle, Data cables, laptop etc. You should check your kit properly working and properly setup. Also check site data, mapinfo etc. should be installed on your system.
- Make sure all USBs are properly attached and must not be loose, otherwise it will create problem while drive testing
- At physical optimization time, you should have proper safety measures.
- First analyze the problem, then start driving to optimize the network problem.
- Dont forget to play and save logfile before starting drive testing.

What Is Software Engineering and What Is It All About
What Is Software Engineering and What Is It All About? - Program engineering is the engineering self-discipline through which programs are developed. Commonly the procedure includes finding out what the consumer wants, writing this in a list of specifications, creating an structure able to support all of the specifications, creating, coding, examining and developing the individual parts, examining the whole, implementing and keeping the applying. Programming is only a small sector of software engineering.
Software engineering (SE) is concerned with creating and keeping software techniques that act effectively and properly, are affordable to develop and maintain, and fulfill all the specifications that customers have described for them. It is important because of the impact of large, expensive software techniques and the role of software in safety-critical programs. It combines considerable arithmetic, information technology and methods whose roots are in engineering.
The self-discipline is still in its childhood (early stage of growth/development) as an engineering self-discipline. We havent had enough experience, nor collected enough scientific data to consistently understand and estimate the life-cycle of a program project.
The Program Technological innovation Body of Understanding separates software engineering into 10 knowledge areas:
1) Program requirements
2) Program design
3) Program construction
4) Program testing
5) Program maintenance
6) Program settings management
7) Program engineering management
8) Program engineering process
9) Program engineering tools and methods
10)Software quality
History of Program Engineering
The record of processing is a little younger than human beings, but research of this particular area was presented in 1968. The basic purpose bifurcating it with other processing places was to get over and fix the turmoil being confronted by the applying companies at that time. It has been known that software engineering provides software strategy to apply and present a considerable strategy to be able to systemize the whole software or application.
Software engineering has been quantified as the incorporation and use of considerable topics and regulations relevant to arithmetic, pc research and various other regulations of relevant places and not to forget the company area for which the applying is being developed. Basically in any kind of engineering all the relevant places and topics are relevant and synchronized to a certain problem to be able to take care of it.
So, in short what is software developing? It is a systemized strategy of creating and renovating of software. It includes the use of engineering to various Programs. In other words, this area includes applying the skills of engineering to software. It is, therefore, a simply pc relevant research.
Further Interpreting Program Engineering
When one discovers the answer to the concern �what is software engineering�, then there are some particular descriptions to describe this term. As it is determined, Program engineering is a properly systemized strategy of creating, evaluating and assessing of software. Along with the creating and evaluation of the applying, software also needs to be examined and all the projects are conducted by software technical engineers. In addition to this, re-engineering of the applying can also be done if you have got a complete knowledge and information of the area.
Why Program Engineering
Software Technological innovation can be taken as a occupation only after reaching the degree of a particular certification. The focus of software engineering research is to provide the students with knowledge so that they can play their aspect in growth, research, examining, etc properly and the program can be developed properly. Programs can be created or customized in such a way that they meet the intended need, objectives and cost also continues to be in check.
When most individuals ask the concern what is software engineering, it shows that the general understanding toward the whole software engineering idea is limited and individuals need to be knowledgeable about the abilities and boundaries of software engineering. Program engineering is a specialised area with further sub-fields within it. Program engineering is not only about creating or perceiving the applying programs as there are other places too such as examining and company research.is.
