2. What is a wireless network?
• Independent, unguided EM waves for specific purpose.
• Systems that convey information between two or more locations.
• Different modes of EM energy for transmission of data.
• Source -> Transmitter -> Modulated Signal -> Receiver -> Destination

12. Does 5G cause cancer?
• “Possibly carcinogenic to humans” – IARC
• “No adverse health effects from low level,
long term exposure to RF have been
confirmed” – WHO
• “Further experimental and epidemiologic
studies are urgently needed ” – IJHEH
• “Male rats exposed to high doses of radio
frequency radiation developed a type of
cancerous tumor in the heart” – US
