On-line: TCP/IP in the Mobile World

On-line: TCP/IP in the Mobile World Training Course Overview

The on-line TCP/IP in the Mobile World course provides training in TCP/IP architecture and IP-based networks (e.g. Internet). The course is an on-line course enabling it to be undertaken anywhere that access toth e Internet can be gained.

The TCP/IP in the Mobile World course focusses on the use of TCP/IP in mobile networks. The course describes IP, Internet Protocol transport used in the access networks (UMA/GAN and eUTRAN) as well as in the core network (split architecture, IMS and EPC).

The course also covers protocols and mechanisms used in a TCP/IP network. These include aspects such as DNS, DHCP and RADIUS. The on-line training course also outlines different aspect of voice and multimedia transmission using Voice over IP and multimedia over IP services. These have a focus on SIP-based solutions.

This TCP/IP in the Mobile World training course has been developed for telecommunications professionals working with project and product management, system engineering, hardware and software development, testing and verification, network planning and operations engineering. As a result it is suitable for most people involved or about to become involved in this area of technology.
