https://devzone.nordicsemi.com/f/nordic-q-a/83782/nrf9160-modem-rf-stopHello I am using the NRF9160 and I can see that modem RF transmitions cause some EMI issues I would like, for a period of few seconds each time to stop modem transmitions can I do that without using the API : lte_lc_power_off ? thank youen-USTelligent Community 13Wed, 19 Jan 2022 12:55:13 GMThttps://devzone.nordicsemi.com/thread/348505?ContentTypeID=1Wed, 19 Jan 2022 12:55:13 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e86dd02e-c426-492d-8b6e-4778e2d852e6Charlie<p>Hi llan,</p> [quote user=""]I can see that modem RF transmitions cause some EMI issues[/quote] <p>Do you mean nRF9160 causes EMI interference for other devices?</p> <p>If so, nRF9160 should operate under the regulation of your country or area and you may think about improving the&nbsp;RF interference tolerance capability of other devices.</p> [quote user=""]can I do that without using the API :&nbsp;<span>lte_lc_power_off&nbsp; ?</span>[/quote] <p>Then why do you want to avoid using lte_lc_power_off? If you do need it, maybe a hardware solution like switching off the antenna is a choice?</p> <p>Best regards,</p> <p>Charlie</p><div style="clear:both;"></div>
