 This
solution corresponds to a scenario presenting a dispersion
of the subscribers around the local exchange. In this
case, the subscribers are covered directly by BSs installed
on a pylon beside the local exchange.

This solution is used when the telegraphic infrastructure
exists. Indeed this solution is used for subscribers who
are not located around the local exchange but can be covered
by BSs located no more far from the local exchange than
4 Km.(see the animation) |

|

 |
|
This scenario is considered if the distance between the
subscribers and their local exchange exceeds the covered
zone by the BS or if there are obstacles. In this case,
we use a RBS to relay the BS.(see the animation) |

|
If the distance between the subscribers and their local
exchange would exceed 25Km and that the two preceding
solutions are unrealizable because of the factual information
of the site, a deport of basic station is technically
necessary. In this case, a BSD is used with a MIC (E1)
link from the exchange ensured by a FH connection.(see the animation) |

 |
|
This scenario envisages a deport of basic stations by
a BSD and a relay by a RBS. This solution is possible
when the constraints relating to the obstacles and distances
impose it.(see the animation) |
