Hi There !

Does the EM7565 transmit on the diversity antenna port ? Its my understanding that some higher speed LTE categories support this, but I’m not sure if its implemented (or used in practice). We are working on placing antennas and a nearby GPS that we do not want to interfere with

Thanks,

/Otto

@otto

No, the EM7565 has a single transmitter which comes out of main, the diversity/MIMO antenna port is used for receive only. You can see this in figure 2-2 of the [PTS](https://source.sierrawireless.com/resources/airprime/minicard/75xx/airprime_em7565_product_technical_specification/#sthash.ZyQAbjpI.dpbs).
