IP has fundamentally changed the way that transmission is employed in Next Generation Networks. This started with the rationalization of the core network in mobile service provider’s networks and has now extended to the RAN core and down towards the cell sites. The deployment of IP in these environments comes with a multitude of challenges that require a number of technologies and protocols to overcome these. This course explores these technologies and challenges as well as the planning and dimensioning of the core and RAN in order to deliver voice, multimedia and data services effectively to the end subscriber. Those attending this course should have a good understanding of IP as would be gained by mpirical’s course IP in the Next Generation Network.
Who Should Attend
Transmission Engineers and Network Planning Staff who require an in-depth understanding of the deployment of IP in NGN in support of real and non real time services.
