Issue Antenna GAIN WLC 5520 - AIR-ANT2513P4M-N

Hola a Todos/as!!

Quisiera consultarles si pueden darme una mano con este tema.

Tengo un WLC 5520 Version 8.2.151.0 en donde no puedo configurar las potencias de las antenas en mas de 12 (que multiplicado por 0.5 me da 6) cuando estas antenas son de 13Dbi

Estuve leyendo que vía CLI se podría forzar a que el wlc configure un numero mayor que 12, pero no logro realizarlo.

Los APs en donde estan instaladas estas antenas son modelo 3702e,

Puede ser tambien que este haciendo una lectura errónea del documento, y seria bueno que me lo marquen si es asi.

Ahora, la idea de setear correctamente el parámetro de dbi de las antenas es para que el WLC pueda hacer un uso correcto del algoritmo con el que calcula cobertura , ruido etc etc.

El mensaje que da el WLC al momento de configurar un numero mayor a 12.

Antenna Gain 26 is an invalid value. Valid Range is <0 - 12>

Muchas gracias por la ayuda que puedan brindarme

I think that is where your problem lies - that antenna is not compatible with 3702e!

Hi @diegs_teco - as I recall the radios on the regular APs cannot support the high gain antennas and could be damaged by them.
The radios on the 3702P are specially modified to work with the high gain antennas.

Gracias Rich R por la respuesta. El que NO sea compatible afecta solo a la configuración máxima de dbi o tambien su funcionalidad?

Thanks for the reply, Rich R. Does the lack of compatibility only affect the maximum DBI setting or also its functionality?
