DVB-T2 system and network design

PROGIRA® academy provides a custom five-day course in DVB-T2 including T2 Lite system, network planning, network design, network architecture and measurements.

 

Course objectives

This training course aims at providing theoretical and practical knowledge about the DVB-T2/Lite system and how to build a transmission network. The course covers the complete distribution chain to the network planning and implementation. After completing this course, delegates will understand the technology behind DVB-T2 and have basic guidance on planning and implementing DVB-T2 network. Particular focus is on SFN network design and implementation.

During the course we also establish a “full” DVB-T2 distribution chain in order to demonstrate features of DVB-T2 and options in network deployment.
Parts of the content can be customised into an interactive workshop where the particular needs of your organisation are dealt with. This option is particularly useful for organisations before the actual deployment of a T2 network. This is one of our most appreciated courses.

Duration: 5 days

Target groups: Operators, broadcast planning engineers

Prerequisities: Basic knowledge of radio communication technology

Participants: Up to 25 people

Language: English

Location: This course is either held at the Progira premises.  Or at Your premises.

Lecturers: Mats Ek, Technical Director PROGIRA / Kenneth Wenzel, CEO, Open Channel | U-Media
