Proposal for a way to proceed
Regional Workshop and frequency
coordination meeting on the transition
to Digital Terristrial Television and1 the
Digital Dividend
Principles
•
This contribution aims to propose a way to establish possibilities
between countries to deploy DTT
•
The figures presented are examples in order to illustrate the ideas
•
All the ideas are welcomed !

Principles
•
Step 1 : identify compatible frequency assignments (sites, power,
antenna characteristics and frequency channels) that may be used by
each country for digital television without harmful interference

Step 1

Principles
•
Step 2 : identify the number channels registered or in use for each
country for the main transmitters per layer
•
Layer : complete coverage of an island by the main transmitters for the
same program

Principles
Nessecity for 3 channels (8
MHz) to provide the coverage
of Guadeloupe for the same
program

Principles
•
Step 4 : identify the target number of layers for each countries taking into
account the number of neighbours
•
For exemple : 2 layers

Principles
•
Step 5 : distribute the channels on an equitable access basis, taking into
account the small transmiters in use
