Can you count how many devices you use every day thanks to radio waves? It can be a bit overwhelming to think about just how impacted our lives are by the utilization of this technology. From smartphones to laptops, GPS to baby monitors and more, we’ve come to harness this form of electromagnetic energy to create some amazing things. But while we use these devices each and every day, do we truly understand how they work?

By playing any such slot machines for just a few spins, it was then possible to work out whether the slot machines was about to pay-out, and players would be able to work out when to click onto the spin button at just the right time that a random number would be selected that had a winning combination attached to it.

That’s where our Wireless Electronic Basics series will help you understand the foundations of our wireless world, and hopefully, dispel some mysteries along the way.

The Wide World of Wireless

Before even diving into any of the science surrounding radio waves, we have to give this subject some justice by showing just how much radio waves have affected our everyday lives. Let’s start with an average day, and perhaps you wake up to the not so soothing sound of an alarm clock thanks to your smartphone. You can thank radio waves for the early morning jolt.

As you sit down for your morning breakfast, maybe you turn on the radio or television to listen to what’s happening out in the world. How are these bits of audio and video information getting to you? With radio waves yet again. And as you get ready to leave for work, maybe you like to check the traffic and plan the most efficient route, so you use the GPS on your car’s dashboard. More radio waves.

During your morning commute, you might like to tune into your favorite morning talk show. The radio station that you plug into is one of many specific radio wave frequencies being transmitted at all hours of the day. When you get to work, maybe you’ll plop down in front of a computer and connect to the world wide web, wirelessly. You load up your Google docs, websites and email, all using radio waves to connect wirelessly to the internet through WiFi.

You see, radios waves are used in many more things than the square boxes that we use to play music and listen to talk shows. Modern wireless communication builds off of simple design inside the conventional radio, allowing us to connect humanity all around the world with information, video, audio, data, and a whole lot more. But for how widespread radio waves are in their use today, how exactly do they work, and what is a radio wave? Let’s explore.

Hanging Out with Electromagnetics

Radio waves are but one type of wave in what’s called the electromagnetic spectrum, which consists of a variety of waves that all serve a specific function, like infrared, x-ray, gamma rays, and radio. All of these waves manage to defy physical barriers, hurtling through the vacuum of space at the speed of light.

The electromagnetic spectrum is more than ROYGBIV, low frequency and low wavelength on the left. (Image source)

The organization of this spectrum is categorized by two measurements, frequency, and wavelength. Here’s how they breakdown:

• Frequency. This is basically how many electromagnetic waves will pass through a given point every second. You can measure this by counting the crests of each wave (the highest point in the wave), which provides a value in Hertz.
• Wavelength. This is the actual distance that you can measure between two of the highest points in a wave, or the period. Wavelengths can be shorter than the size of an atom for some waves, and longer than the diameter of our entire planet!

All the waves in the electromagnetic spectrum are measured by both their frequency and wavelength.

On this electromagnetic spectrum, radio waves have both the longest wavelengths and the lowest frequencies, which makes them slow and steady, the long-distance runners of the bunch. However, when we’re being bombarded from all directions with FM and AM radio waves, cell phone signals, WiFi signals, and more, can all of these signals supposed to share the same space? They do this by sharing specific bands in the radio wave spectrum, and these include:

The ultra high frequency (UHF) band has a frequency between 300 megahertz (MHz) and 3 gigahertz (GHz). You’ll find the UHF band used for specific technologies like WiFi, Bluetooth, GPS, walkie-talkies, and more. On the flip side, you’ll find very low frequency (VLF) in the 3 – 30 hertz range and this band is reserved exclusively for government radio stations, secure military communications, and submarines. The United States publishes an annual Radio Spectrum Frequency Allocation chart that shows how all of these radio services are allocated per frequency.

Embedded Communications

Now you might be wondering, how exactly do those radio waves in their particular frequencies get from place to place? The magic of being able to talk with someone on your smartphone halfway around the world boils down to some very simple principles. Every radio, whether it’s a traditional AM/FM radio or a radio found in a smartphone, all uses the same basic method of transmitting information with the help of both a transmitter and a receiver.

A transmitter, as its name implies, transmits information through the air in the form of a sine wave. This wave goes flying through the air, eventually being caught by a receiver, which decodes the information within the sine wave to extract the stuff we want, like music, a human voice, or some other bit of data.

All of the information we can decode from a radio wave is transmitted as a sine wave.

What’s interesting is that a sine wave alone doesn’t contain any of the data that we need, it’s basically an empty signal. This is why we need to take this sine wave and modulate it, which is the process of adding another layer of useful information. There are three methods of modulation, including:

• Pulse Modulation. In this method, you are turning a sine wave on and off, which will send bits of a signal in separate chunks. Ever heard of Morse Code to send distress signals? It uses pulse modulation.
• Amplitude Modulation. This method is used in both AM radio stations and those old analog TV signals. Here, a sine wave is overlaid with another wave of information, like a person’s voice. Embedding another layer of information in this wave will create a fluctuation in the amplitude of the original sine wave, which can create static.

When you combine a sine wave and modulated wave signal together, it modulates the original signal. (Image source)

• Frequency Modulation. This method is used by FM radio stations and virtually every other wireless technology out there. Unlike amplitude modulation which creates some significant fluctuations in a sine wave, frequency modulation changes a sine wave very little, which has the added benefit of resulting in less static.

Modulating a sine wave with a frequency signal results in less modulation than an amplitude modulation. (Image source)

Once all of those modulated sine waves are sent via a transmitter and received by a receiver, the wave of information that we embedded gets extracted, allowing us to do with it as we please, like play it as audio through a speaker, or view it as video on a television screen.

Somewhere Between A and B

In our explanations above about modulation, transmitters, and receivers, you might think that sending a radio wave is a simple process of travel from point A to point B, but this isn’t always the case. Waves don’t always fly through the thin air straight from a transmitter to a receiver, and how they travel ultimately depends on what kind of wave frequency you want to send, and when. There are three ways this journey can happen, including:

Line of Sight (Space Wave)

With this method of travel, radio waves are sent as a simple beam of light from point A to point B. This method was commonly used in old-fashioned telephone networks that had to transmit calls over a long distance between two massive communication towers.

Ground Wave (Surface Wave)

You can also send radio waves along the curvature of the earth’s surface in the form of a ground wave. You’ll find AM radio waves traveling in this manner for short to medium distances, which is why you can still hear radio signals even when there isn’t a transmitter and receiver in your line of sight.

Ionosphere (Sky Wave)

Last, you can also send radio waves straight up into the sky, which ends up bouncing off of the earth’s ionosphere, which is an electrically charged part of the atmosphere. When you do this, the radio waves will hit the ionosphere, bounce back down to earth, and bounce back up again. This is the process of mirroring a wave, bouncing it back and forth to its final destination.

We have all three methods of travel a radio wave can take, via ground, space, or sky. (Image source)

At this point we’ve gathered several things about radio waves, namely that they travel at very specific frequencies, they communicate with both a transmitter and receiver, and they can travel in a variety of ways across the earth. But with all of the different radio frequencies floating about, how does your smartphone or car radio know which particular frequency receive, and which ones to ignore? There is where antennas come into play.

It’s All About Antennas

Antennas come in a bunch of different shapes and sizes, but they’re all designed for the same purpose – to pick up a very specific radio wave frequency. You’ll find antennas ranging from the long metal wires sticking out from an FM radio to something rounder like a satellite dish, or even a tightly tune piece of copper on a PCB. In a transmitter, antennas are used to send radio waves, and in receivers, they’ll be used to pick up on a radio frequency. Antennas all have three distinct features that they’re measured by, including:

• Direction. For some antenna types, such as a dipole, the antenna has to be mounted in the proper direction, facing the direction of the radio wave transmission. Some antenna types, like those found in an FM radio, don’t need to be oriented in a specific direction and can capture radio wave signals from any angle.
• Gain. The gain of an antenna describes how much it is going to boost a signal. For example, if you turn on an old analog TV, then you’ll still likely get a picture, just a fuzzy one. This is because of the metal case and components in the TV act as an antenna. But plug an actual directional antenna in, and you’ll be able to boost the signal, and gain a better picture. The bigger the gain, measured in decibels (dB), the better the reception you’ll get.
• Bandwidth. Last, an antenna’s bandwidth is its particular range of useful frequencies. The higher the bandwidth, the more radio waves that it can pick up. This is ideal for televisions as it allows them to get more channels. But for things like your smartphone which only need a specific radio wave, a full bandwidth isn’t as necessary.

Time to Phone Home

Radio waves are everywhere! Imagine if you could see them with your very own eyes. You’d have radio waves all over the place, beaming out of your router, from your cell phone, and all around you from your neighbor’s wireless electronics. Radio waves have indeed shaped our modern lives like nothing else, and without them, we would never get to enjoy such useful inventions as GPS, WiFi, Bluetooth, and more. But radio extends far beyond our physical, earthly existence. Some of the farthest reaches of our known universe have been explored through the use of radio astronomy to discover quasars, molecules, and other galaxies!

If you had put in one or three coins the outcome would likely have been entirely different. The machine is constantly drawing random numbers and the numbers that were drawn at the moment you spin the reels determine the outcome. So, if you had played fewer or more coins you would have spun the reels at a different moment and thus the outcome would have been different.

Thanks for the kind words Dave. You're right that it was the money that finally made me accept the banners. It is my understanding that when the player presses the button to spin the reels the random numbers are drawn at that instant, which determine where the reels stop, and ultimately what you win. The number of coins bet does not matter.

Thanks for the compliment. The outcome of the game is determined when the player initiates the spin. The game is constantly drawing random numbers, even when not played. The random numbers chosen at the moment the button is pressed to spin the reels determine where the reels stop, which determines what the player wins. So, if the player bet three coins he would have pressed the button at a different moment, causing a different outcome.

No, that information won’t help you at all. Your odds are always the same on every spin, regardless of the counters.

To answer your question I asked a well connected gaming consultant and he said Nevada regulations state that one stop on a reel can not be weighted more than six times more than either stop next to it. So if a jackpot symbol were weighted by 1 and both bordering blanks were weighted by 6 then there would be 12 near misses for every one time the reel stopped on the jackpot symbol. This would be the maximum allowed near miss effect. My own results detailed in my slot machine appendix 1 back up this theory well. The red double seven was the highest paying symbol and I saw the blanks above and below it about 5 to 6 times as often:

The same source said that New Jersey and Mississippi likely have adopted the Nevada regulations.

My understanding is that the person who is pressing the buttons gets the money. I asked Brian, who helped with the last question, about this. Here is what he wrote, which I agree with.

In the scenario described, the person who put in the money and pressed the buttons would receive the jackpot.

What I find interesting about this question is the paradox that in all likelihood, the jackpot never would have occurred without this chance encounter.

As you know, the random number generator in the slot machine is continuously working even when the machine is not in play. So even though one patron feels cheated, their run-in ultimately led to pressing the spin button at that exact millisecond when the RNG was on the winning combination. So, if one patron had acquiesced, there is never a jackpot to fight over.

Thanks for helping in the fight against betting systems. First let me say that I have never worked for a major slot machine company and don’t have direct knowledge of this. However, I know many people in the industry and those I trust pretty much are in agreement on this topic.

That said, it is my understanding that in all forms of electronic games, including video slots, video poker, and video keno, the outcome is usually determined the moment you make your decision. Meanwhile the possible outcomes are constantly being shuffled, thousands of times a second. I can’t speak for every slot machine but I believe that with the major U.S. slot makers the outcome is not predestined but depends on the exact microsecond you press the button to make your play.

Thanks for the kind words. Scratch cards and pull tabs can indeed be printed in batches. These batches will have a specified number for each win, and the return of the overall batch will be exactly as the maker intended. In some jurisdictions, where only pull tabs are legal, the outcome can be displayed to the player on a video monitor, in the form of a slot or video poker machine. However, in Nevada, that is not how slots work. Each play is completely independent of the past. A machine programmed to average a 97% return, could indeed pay under 95% or over 99% over a year, especially if not heavily played.
