Drive Test Data Capture and Analysis
Drive Test Data Capture and Analysis Drive-testing to record and analyze real network performance is a critical function for effective radio network optimization. Modern drive test tools have a lot of capability and frequently much of it is left unused by drivetest and optimization teams. This Wray Castle course provides a guide to the capabilities of typical drive test tools and describes how data is captured and how it should be interpreted. The course is practical based and incorporates some precourse study. It can be run on any drive test tools with appropriate lead times and equipment availability.
The delegate will learn how to set up and configure hardware and software for the tool. Commonly used and more advanced tool features are demonstrated and then practised through a series of exercises. Circuit-switched and GPRS operation and testing are covered, as well as UMTS testing. A series of example drive-test log files are used for demonstrations and exercises in data interpretation and report generation.
Who Should Attend This course is designed for engineers working in optimization or quality analysis teams for network operators, consultancies, and software tool manufacturers who wish to improve their skills with drive-test tools.
All the practical elements in this course are carried out on a live network or use log files recorded from a live network. Since this requires the cooperation of a network operator this course is most suitable for group bookings where appropriate access to a network and drive-test equipment can be arranged.
Learning Objectives On completion of this course the delegate will be able to: n
explain the UMTS measurement and reporting process and parameters and identify the key handover measurement event triggers
n
describe and interpret signalling flows and failure messages, signal strength and quality measurements
n
explain the UMTS measurement and reporting process and parameters
n
identify the key handover measurement event triggers
n
create and organize a workspace for the display of GSM and UMTS captured data
n
perform a drive test in a vehicle
n
establish a connection to the Internet via GPRS and UMTS and perform tests by downloading web pages
n
write command sequences for HTTP and FTP that can be used for packet data testing
n
interpret UMTS radio parameters and channel configuration parameters
n
recognize important UMTS call and procedure events
n
interpret displayed data and report on events and failures in a range of example GSM/GPRS log files
n
interpret displayed data and report on events and failures in a range of example UMTS and dedicated scanner log files
n
shortening the learning curve and speeding productive inputs from new team members and freeing more experienced employees’ time
n
evaluating better a system’s capabilities through improved knowledge, leading to superior operations and maintenance performance
n
providing greater confidence in the sale of equipment by anticipating customers’ technical requirements and being able to promote relevant superior equipment performance
Benefits In addition to gaining a good understanding of drive testing, this course will enable the delegate to deliver operational improvements and generate cost savings or reduce project timelines by: n
improving network design, planning, operations and maintenance
n
avoiding the laborious search through specifications, standards and white papers, while benefiting from a practical analysis and interpretation of such documentation by experienced engineers
n
knowing better where to look to accelerate research and fact finding and facilitate earlier project completion
n
improving the equipment procurement process by better analysis and challenge of technical specifications and supplier responses, thus giving greater certainty to on-target performance and value-for-money purchasing
and, after the course, Wray Castle’s unrivalled post-course support comes into effect.
