Asunto:  Problemas de Rendimiento en Velocidad 3G

Dedico unas líneas a aquellos navegantes deslocalizados o localizados que usan 3G UTMS o cualquier otra tecnología telefónica para conectarse a internet.

Mi padre lo usa (le sale mas barato que el ADSL) y estuvimos haciendo pruebas de velocidad. Dedicamos muchas horas y las conclusiones son realmente sorprendentes.

1º NO USAR NINGÚN TIPO DE ALARGADOR ENTRE PC Y EMISOR 3G.

2º no hay ninguna otra opción posible je je.

En fin, que da igual que alargador uses (blindado, sin blindar, de 20 cm de 5 metros), lo que mejores de señal (sacarlo por la ventana, hacer el pino de nariz) o hagas lo que hagas... cualquier cable USB que utilices para conectar con el emisor reducirá unas 10 veces el ancho de banda.

El motivo no lo tengo muy claro pero parece que es un problema de interferencia en la frecuencia del usb con la del UTMS. En teoría con un cable apantallado no debería de haberla, pero no es así. El cable USB funciona amodo de antena e interfiere en el 3G.

Por tanto, si usas 3G no uses en ningún caso ningún tipo de alargador, hub o cable, siempre conéctalo directamente a un puerto USB de la placa (que no tenga cable de extensión).

ok, recibido!!! gracias por la info siempre ens bueno saber estas cosas....

yo uso actualmente un stick usb sin cable, pero tuve uno al principio que venia con antena, bueno en realidad era una pcmcia de las antiguas grandes que venia con una antena tipo "palo de medico" y con un cable de 10 cms escasos. El caso es que se me rompió la conexión y siquio funcionando mas o menos bien..( dentro de que la tecnología 3g estaba empezando y tenias muchos problemas, tanto por cobertura, como cuando ibas en movimiento y trataba de cambiar de 3g a gprs o simplemente cambiar de zona osea de antena)

Pensandolo bien....

!!!El mundo avanza que es una barbaridad!!!!
