It is my understanding that 3G is going away in June 2022. We are paying for 2 antennas for the EM7455 and I think one of the antennas is for fallback to 3G. Does this mean I can omit the expense of this 3G antenna?
I think if there is no more 3G network in your area, you can use other antenna
To be clear, are you saying the AUX antenna will no longer be used on the EM7455? I assume the MAIN antenna is the 4G only.
The antenna ports on the 7455 serve both 3G and LTE, you need both antenna ports for both technologies to be able to hit peak data rates.
