Le système utilise des baies Nokia (sur base Alcatel) et est déployé par Deutsh Telecom. Il y a une trentaine de sites en France, qui doivent être pour la plupart chez TDF. La baie utilise le réseau de transport fibre/FH de TDF.

Curieusement les antennes ne semblent pas avoir de tilt vers le ciel.

Probablement des antennes spécifiques :
- gamme de fréquence 1980-2185 Mhz sur les spécifications de l'antenne - 4 ports
- les RHHs sont 4RX/4TX aussi.
Radius de cellule allant jusqu'à 150 km.

Hi
Your antennas are not accepted how is installed . As you know the name is AIR TO GROUND so the tilt shoul be ZERO OR " -".There is down tilt not UP TILT .
-
Hello Rexum00s, welcome
It depends where is placed the antenna, if it is in height it can explain the tilt ;)
-
Wrong answer bro.For this project only uptilt and zero never downtilt ..;)
The photo which are here are from Bastia .. check label from door of rack

Hi Ginie
You have right this project was made by Nokia Romania. Is not a project for France is for all Europe and is under Nokia and DT .
But as I write, sometime is happened perhaps the site documentation was wrong.( I working for this project now ) . For next week should go to change a tilt from -5 to zero . and I though for this site me or Circet team should go to change this built fault .
So sometime is happened , you know that , without any reason from team who do this job . . . . In maximum 1 month will start tests for this network
-
We've made tilts change on Ajaccio last month but no demand on Bastia.

I know that ,we will see after tests because for France was not done those tests... . But I.m sure the tilt is wrong because there is somewhere -7 or -8 (downtilt)
-
You perform also integration for site from France ?!
-
i don't think

...the world’s first integrated S-band satellite...“The network is specifically designed to meet future capacity demands for connectivity in the European airspace...
