Communication is very important in human society. The more technical and mobile we become the more important it is. If someone is 500 miles from home and has an emergency they will need to contact home. Today we have very advanced communication systems. Controlling those systems helps you control society. In 2007 PBS in San Diego produced a Frontline documentary about surveillance in America titled "Spying On The Home Front". In that documentary they said that ATT in San Francisco was providing all internet traffic to the NSA via a NARUS ST6400 splitter. It was authorized to do so by congress in the Patriot Act after Sept 11. It's possible all internet traffic in America is being monitored by the Federal government along with phone calls and cable TV. If the Federal government has access to all this it's possible that other people do to. Anything can be hacked into.

There are a few things that can be done to get around this. Some simple, some not so simple. There is an entire building in almost every town in this country dedicated to communications. In the city's there are numerous buildings. For any communication that involve a wire it is where the wire terminates and connects to the greater network. If it's wireless it has to have some sort of central facility to route the data, connect to the greater network. To prevent wireless intrusion all of these buildings should be turned into Faraday Cages. Preventing intrusion into the wired network is more complicated. Getting rid of things like the NARUS ST6400 would certainly help.

A way to get around all of it would be to design a completely different system that cannot be controlled and that is free of cost. Ham radio offers a solution. Ham radio operates what are called repeaters. It is a piece of equipment, usually in an isolated area, that picks up weak signals, strengthens them and then rebroadcasts them. WiFi extenders are basically the same thing. (see picture) The entire network would be a system of repeaters. Every house and apartment would have a extender that picks up signals nearby and relays it to the next. To get signals from one town to the next repeaters could be put in isolated areas or very strong signal boosters could be put on the edge of town. For the most part no central facility would be needed and the only cost to everyone would be the equipment. It might be possible to get an iphone to talk to an iphone like a Walkie Talkie. Or any Android based phone. They allow anyone to develop an app for Android. You can download the Software Development Kit (SDK) for free.

The radio frequency spectrum extends from DC (0hz) to about 3thz (3,000,000,000,000 hz). Anything above that becomes light. The microwave spectrum is anything above 300 mhz. There are numerous types of modulation. Modulation is accomplished by varying one factor of the given wave. (ie frequency, amplitude, etc) Thus the names frequency modulation (FM) and amplitude modulation (AM). Ham radio operators are restricted to certain frequencies and types of modulation. It's possible to create a relay (repeater) system with any frequency and modulation type. You could create one that operated in the FM and band but worked on amplitude modulation. Technically it's against the law but so is what the government is doing.

At some point in the future it might be useful to jam everything but one band of frequency's. (see picture below) Design a noise generator that produces noise over the entire frequency spectrum then filter it for a specific band and put the noise through a mixer circuit along with the data. All broadcasting equipment should be limited to 25 Watts.

I recently watched a couple videos about people designing alternative DNS systems. I don't think this is totally necessary. At least not in small towns. DNS stands for Domain Name Service, or Server ??,. It is a way to route a communication. It's like an operator in the early days of telephone. Operators sat at a board and physically made the connection to route a call from one place to another. Today it's done automatically with computers. DNS is the internet equivalent. Lets say you had a small town of about 50,000 people. Everyone's communications are wireless and handled on one frequency in the microwave range. Everything else was jammed with noise. If someone's call bounced around the entire town looking for the right end point it wouldn't take much time and you wouldn't really notice anything. The frequency is so fast. This is a roundabout example. Anything above 10 hz is not visible to the naked eye. If you pulsed an LED you would see it like it is on all the time once you get it above 10 hz. Any LED monitor or TV has 1000's of LED that are pulsed many times per second. But it appears to be on all the time. The same effect could be used with voice communications and maybe the internet. Eventually someone might come up with a method to avoid this and save bandwidth and still have no central facility.

I have a laptop with Windows 10 on it. No matter what I do I can't get it to stop updating automatically. And I can't remove the HP assistant. I think the tech companies put spyware and viruses on the computer with the updates. I also have a Google Android phone that does as it pleases. I use Tracfone that comes with data but it never works. When I buy a new PIN it works for about 24 hrs then stops. The notification icons have a mind of their own. Sometimes they show up, sometimes they don't. The storage is encrypted but I didn't do it. There must be a way to physically separate the antenna input from the operating system, permanent memory and working memory. You could have a completely separate connector to install or update the software. You would have to have actual possession of the phone to change any software. Why does the FBI, and the federal government, not want you to encrypt your communications? I think they want your hard drive encrypted but not your communications. I wonder why?

R.S.A. is a company that deals in cryptology. It stands for the 3 people who started the company. Ronald L Rivest, Adi Shamir and Leonard L Adleman. They came up with what many consider the gold standard in encryption technology. They are mentioned in the documentary "Missing Links". It's about the Sept 11 attacks. Most of the evidence presented was gathered by present and former members of the FBI, CIA, NSA and military intelligence that are still loyal to the United States. That's what it says at the very beginning of the movie. The algorithm used by RSA would take years for the most massive computer to decipher just one message.

The trick to RSA is a public key. Any RSA encrypted message can be unlocked if you have both the private key and the public key. I don't totally understand it. But somehow the possibilities are so enormous it would take the biggest fastest computer years to decipher one message.

The picture below is potting fluid. In electronics potting is a process of filling a complete electronic assembly with a solid or gelatinous compound for resistance to shock and vibration, and for exclusion of moisture and corrosive agents. Thermosetting plastics or silicone rubber gels are often used, though epoxy resins are also very common. Many sites recommend using a potting product to protect sensitive electronic components from impact, vibration, and loose wires. If you want to stop someone from siphoning off data or voice (NSA or CIA or FBI) from communications equipment you could disconnect the cable they're using and pour some of this into the connector on the PCB board. They would not be able to re-connect it.
