En entrée, il existe un réseau assez important basé sur la solution Cisco, qui fonctionne depuis plus de 10 ans et se compose de:
1 348 bâtiments et structures;
10 030 types différents de points d'accès de production, à commencer par les ordures AIR-LAP1131G, AIR-LAP1041N (environ 88% du total), se terminant par d'assez bons CAP1602I, CAP2602I, CAP1702I, AP1832I;
WISM1, WISM2, WLC 8540.
Pendant plus de 10 ans de fonctionnement, les lignes de câble ont commencé à devenir inutilisables à la suite de divers réaménagements et révisions. Un grand nombre de points d'accès et d'injecteurs de puissance ont commencé à tomber en panne, ce qui, combiné à la tendance à la hausse de la consommation de trafic, a conduit à des plaintes constantes sur la qualité de service.
Compte tenu du calendrier et des possibilités du budget, il a été décidé qu'au cours de la première étape de la modernisation, les réseaux de 589 bâtiments seront soumis à la décision de poursuivre la modernisation après analyse des conséquences de la modernisation actuelle.
Les tâches suivantes sont formulées:
le remplacement des points d'accès défectueux et obsolètes par des points d'accès nouveaux et modernes;
couverture de bâtiments et locaux supplémentaires;
remplacement des commutateurs d'accès et des injecteurs de puissance par des commutateurs PoE;

Par observation expérimentale du comportement de points d'accès déjà montés, et il y en a plus de 7500 au moment de la rédaction de cet article, on a supposé que les lignes de communication sur lesquelles les points d'accès ont un paramètre de vitesse eth0 moyen inférieur à 970 nécessitent une reconstruction. En commençant par le resserrage des connecteurs RJ45 et en terminant, si nécessaire, par le remplacement du câble. Le nombre de ces lignes de problème au moment de la rédaction de cet article représentait plus de 10% du nombre de points d'accès surveillés.
La tâche des installateurs d'ici la nouvelle année est d'assurer sur 100% des lignes câblées une vitesse eth0 moyenne d'au moins 970.
J'espère que l'article vous sera utile, écrivez vos questions dans les commentaires ...
