Con motivo de la próxima erección del nodo, el sábado 16/02/2008 se realizaron varias pruebas de conexión en la terraza (sobre un piso 22), el nodo actualmente se encuentra en un piso 12. Si bien se pudo asociar a todos los nodos detectados, sólo con NodoMandrake se consiguió un enlace estable y hacer una prueba de trasmisión.

Nota : Todas las pruebas fueron realizadas únicamente por OSiRiS, el cuál tuvo que sostener la antena, el AP y la notebook al mismo tiempo sin caerse ni perder la conexión, seguramente esto influyó mucho en los resultados :-P

Prueba de Trasmisión

Luego de establecer un enlace estable contra NodoMandrake, se accedió por ssh y se realizó una prueba de transmisión mediante iperf.

Conclusión

  1. La altura y los 360 grados de visión cambian completamente el panorama, pudiendo este nodo establecer varios enlaces direccionales con unos 4 o 5 nodos más.
  2. Este tipo de pruebas debe ser organizada y realizada con al menos 2 personas, por seguridad y a fin de hacer mayor cantidad de testeos seguros.

Reacomodando las antenas, hice una prueba y logré conectarme a NodoParis. Hasta subir todo a la terraza queda el Linksys como AP-Conectado con un OvisLink en modo Bridge hacia NodoParis. El enlace si bien tiene algo de perdidas de paquetes está estable.

Ajusto la antena de manera que el viento la mueva lo menos posible y mejora el enlace.
