if they use frequencies, could you access this signal through a second signal of the same frequency?
Wireless signals in computers are based on radio. Radio is the technology that uses electromagnetic signals to communicate.
You have a transmitter that produces an electromagnetic wave and a receiver that receives the electromagnetic wave.
Receivers and transmitters have active electronic components (like transistors) and passive electronic components (like antennas).
There are many types of radio transmissions: narrowband, wideband, ultrawideband, spread-spectrum, ...
Many of these terms relate to the type of frequencies used.
WiFi a and b uses narrowband
Bluetooth and GSM use spread-spectrum
Different types of electronic circuits (receiver and transmitter) are required for these different types of radio transmissions.
However, a new technology has appeared that permits a single electronic circuit to handle all types of radio transmissions: Software Defined Radio
Your cyborg could have an extremely powerful embedded SDR which would permit it to receive and transmit all kind of signals.
Another thing I'm thinking of for your cyborg is high energy particles. Let me know if you want to know more.
