Can Argon/Boron coexist (RFI/EMI?)

I am building out a future HA pair on a tripler board. An Argon, Boron and data logger will coexist in one enclosure acting as an HA gateway device. The Xenons (with GPS and IMU) will be in separate enclosures nearby.

My question is toward RFI/EMI considerations when an LTE and WiFi device are in proximity; has this been tested? I understand the frequency deltas; I am worried about the harmonics of the LTE carrier causing parasitic losses. Has this been evaluated?

Most grateful,
