That layer blocks two categories of electromagnetic radiation: Extremely Low Frequency (ELF) emissions from batteries and power sources (up to 98% attenuation), and wireless Radio Frequency (RF) emissions up to 40 GHz (up to 99% attenuation). The RF coverage spans WiFi, Bluetooth, cellular signals, and low- to mid-band 5G.
