SAT relays of signal on mobile phone frequencies.
The operation and origination of the project originated in Great Britain with Marconi / GEC. Some 26 individuals were killed, the majority of them between 1986 and 1988, presumably to cover up a development.
Q mentioned [3] dead scientists, indicating that of the deaths at Marconi, only three of them are of significance. Presumably, identifying the [3] scientists will lead to the technology developed, which can then be mapped to modern-day cellular developments.
One project that Marconi was involved with was Satellite communication with submarines and another big project was naval torpedo development, which focuses on acoustics. Both of these involve either Extremely Low Frequency (ELF) and Very Low Frequency (VLF) wave propagation.
We also know that the human brain can be significantly impacted by Electromagnetic Frequencies (EMF), also known as Radio Frequency (RF) signals in the 4Hz to 14Hz range (ELF).
One of the major objections voiced about ELF signals is the length of the antenna required to generate such signals. There are two answers to that. First, note this 1988 thesis from the Naval Postgraduate School that lays out a plan for tethered satellites:

Fascinating document if you're interested in that sort of thing. Allows transmissions at massive power from space on ELF and ULF frequencies. Interestingly,
NASA, describe ELF with ranges between the standard 3 to 30 Hz,>0 to 300Hz.and
even, according to WHO, from >0 to 100 kHz. At frequencies this low (>0 to 300 Hz),
"the wavelengths in air are very long (6000 km at 50 Hz and 5000 km at 60Hz), and,
'''in practical situations, the electric and magnetic fields act independently of one
another and are measured separately'''
