Por favor su ayuda. Si el shiled 4G+GPS va a trabajar sólo en cobertura de 3G. Es necesario utilizar las dos antenas 4G que vienen en el modulo.

This module (4G+GPS) includes:
1x 4G Shield (LE910 Chipset)
2x 4G antennas
1x GPS antenna
3x Pigtail uFL-SMAH

Slds,
Louis

Hi louis,

Yes we recommend to use both antennas (normal + diversity) to ensure the good communication of the module.

Regards

Yo entiendo que el dispositivo cuando trabaja en 4G va a utilizar las dos antenas (normal+diversity). Mi consulta es cuando el dispositivo esta trabajando en 3G va a utilizar las dos antenas o sólo requiere de una antena.

Hola louis,
El múdulo tiene 3 antenas:
Antena 1: Para las bandas GSM/EDGE/UMTS. 2G, 3G y 4G utilizan esta antena.
Antena 2: Para el GPS. Sólo necesaria si utilizas el GPS.
Antena 3: RX diversity. Esta antena es opcional y mejora la conexión y la cobertura. Es recomendable que la mantengas. Debe estar lo más separada posible de la Antena 1.
Un saludo
