This shows how you can examine the Radio Frequency spectrum to see what lies in each band. See where 5G, Wifi, LTE, 3G, Ham Bands, Air Traffic Control, FM Radio are. This is an introductory segment. From a basic understanding of RF, we can begin to analyze the dangers of various technologies. Or perhaps safer alternatives. The device I'm using is BladeRF 2.0 Micro xA4, a Transceiver (2 Transmitters and 2 Receivers). All software controlled from a computer. Full Duplex. I will be doing many experiments with this device in future videos. For the moment, we are just scanning the frequencies and listening in where we can. You can scan a portion of the RF frequencies I'm showing here using an inexpensive device called an RTL-SDR. This just plugs into your USB. No FCC license is required to listen. Amazon Link to RTL-SDR https://amzn.to/2GToVlF I'm the Internet Privacy Guy. I'm here to educate. You are losing your Internet privacy and Internet security every day if you don't fight for it.
