 Le probl\u00e8me que j’ai rencontr\u00e9 sur le site de mon observatoire, c’est la desserte r\u00e9seau. La desserte \u00e9lectrique \u00e9tant accessible sans trop de probl\u00e8me (17m), le raccordement r\u00e9seau f\u00fbt tout autre puisque je me suis greff\u00e9 sur une box internet bien mal plac\u00e9e . Le positionnement du raccordement \u00e0 la box assez lointain (30m) et pas de possibilit\u00e9 de passer en filaire sans des co\u00fbts de travaux exorbitants.<\/p>\n

La solution est trouv\u00e9e en passant en tout WIFI avec du mat\u00e9riel semi professionnel et pourtant pas trop on\u00e9reux.<\/p>\n

\"\"
\nLe CPE210 de TPLink est une borne POE qui d\u00e9bite du 300 Mbps en 2.4 Ghz. J’ai donc tir\u00e9 dans le grenier de  de la maison 15 m de c\u00e2ble Ethernet 5e (le minimum pour le POE) et positionn\u00e9 la borne sous la sous pente du toit en ext\u00e9rieur. L’inconv\u00e9nient de ce type d’antenne WIFI c’est qu’il faut une orientation pr\u00e9cise, le fabricant inclus fort heureusement un utilitaire pour cela. On a le choix du mode de fonctionnement AP, R\u00e9p\u00e9teur…<\/p>\n

La port\u00e9e th\u00e9orique est de 2 km entre deux bornes, personnellement sur 50 m aucun souci.  Le m\u00e2t m\u00e9t\u00e9o proche de l’abri dispose aussi d’une borne similaire qui raccord\u00e9e \u00e0 un r\u00e9partiteur dans l’abri permet les liaisons des automates et la continuit\u00e9 du r\u00e9seau interne de l’observatoire.
\n\"\"
\nLes deux bornes sont manageables \u00e0 distance car connect\u00e9es elles m\u00eames sur des prises IP autonomes<\/a> pour la coupure en journ\u00e9e et l’allumage de la liaison en d\u00e9but de nuit. Les prises supportent les commandes SNMP<\/a> ce qui permet de cr\u00e9er ses propres programmes de commande.<\/p>\n

Tout n’est pas infaillible, le goulot d’\u00e9tranglement du syst\u00e8me c’est la box qui en zone rurale dispose d’un d\u00e9bit assez peu enviable. Parfois aussi une qualit\u00e9 de service d\u00e9plorable, tout autant que le support technique du fournisseur.<\/p>\n
