UMA System Engineering (2 days or 12 hours)

For some time, there has been a growing interest in using an alternative, and cheaper, radio access system to improve both coverage and capacity to cellular networks. UMA, now formally GAN or Generic Access Network sets out to combine Wi-Fi with GSM / GPRS and UMTS and so enables true mobility between the different radio access networks. This course sets out to explain the rationale behind this technology before explaining the new architecture and mode of operation - both circuit switched and packet switched. It also explains how mobility is supported before reviewing how UMA is adapting to other wireless technologies and the rise in Femto Cells.

Who Should Attend

This course is designed for Network Engineers involved in the development and deployment of UMA within existing cellular networks and Product Managers requiring a detailed insight into the operation of UMA.
