2G Network QoS and Performance Analysis Duration and Training Format 5-day instructor-led training
Course Objectives By the end of the course delegates will be able to: Develop their understanding understanding of what GSM is and what it can do, includin including g the motivation for its development,, its early history, and its present capabilities. development Help the engineering team in QoS planning, optimization and performance management for the wireless data network. Have a better knowhow of the parameters involved and KPI metrics; Develop their appreciation of how GSM and related technologies can be used to deliver value to customers, including including an exploration of what is meant by "quality of service" and a discussion of the network technology, management management systems and business processes required to deliver customer value; Explore the linkages between technological technological capabilities of GSM and the marketing and pricing decisions that are an essential part of delivering quality to customers
Course Overview The goal of mastering GSM QoS training is to present details and up-to-date information on the GSM standard. Students will become familiar on how to improve QoS and manage performance of the GSM radio network. The participants will learn about practical performance and deployment issues specific to the GSM standard. This course gives the proper knowledge on the QoS as well as the physical method of QoS that is used for Standard Drive Test. Different Statistical methods, such as Accessibility, Availability, Maintainability and Quali Qua lity ty are der deriv ived ed in thi this s co cours urse. e. At the en end d of th the e tra train ining ing,, th the e Qo QoS S per perfor forman mance ce rep report ortin ing g and optimization is focussed.
