All RealPars videos rock! Can't wait to see some real programming in action. Building logical steps and creating algorithms to perform useful tasks is what counts most. It's the essence of programming. Learning the different technologies will follow naturally. Hope to see a small program that controls some devices to perform an action. Stay Safe, RealPars team!
Hi Gassan, Thanks a lot for your kind compliment! We are always extremely happy to hear such positive feedback! If you ever have any questions, feel free to reach out to us. Happy learning!
That depends on several factors. Outdoors, with a clear line-of-sight, a range of 300m is not uncommon. In a building, or wherever there are physical obstructions, the ranges are typically 30 - 100m. These ranges can be extended by using repeaters, mesh networking, and other approaches. Some researchers are looking at what are called Long Distance Wireless Sensor Networks (LDWSN), which may allow transmission distances of up to 12km. Of course, this is not yet commercially available and will be very expensive. Also, limitations in signal strengths allowed in the 900 MHz to 2.4GHz band may make LDWSN impractical for widespread use.
It sidestepped my questions. I want to know what process takes place, in detail, that changes the data into waves. I know it's electromagnetism. How does energy pick up the data and turn it into waveforms of 1 or 0? He says it does that, but how? What details are needed to do that? Does it scan data, take a picture, derive a vibration, pick up molecules, or what? My other question is whether waves turn into mass. How is it possible to send these waves vast distances without degradation? Oh hell. This seems silly now. I'm going to ask chat GPT 4o and get on with it.
Hi, @RobertHouse101. This technology has been around for many years. Even the sun creates frequencies. To understand this, you will have to take a course in electronics. All these frequencies and waveform patterns are explained. I will simplify it for you as it is currently used today to give you a start in understanding. You have a device that takes a digital signal, converts it to analog and turns it to a waveform, sends it to an amplifier, then to a transmitting tower then to a receiving tower, and then converts from analog to digital again for the receiving device. Here is a link for your learning: www.jameco.com/Jameco/workshop/Howitworks/what-is-radio-frequency.html#:~:text=RF%20is%20generated%20by%20a,transmit%20RF%20over%20signal%20wires. Hope it was helpful!
Great channel. ! I would like to run our sports scoreboard wirelessly, for a baseball field. The cable output from the data entry box is a simple TRS cable (like you plug into a guitar), and the same cable plugs into the scoreboard. Can you recommend hardware to buy? (Transmit and receive). Thanks!
Enter "trs cable wireless" into your favorite browser. There are many different devices that may work. I have never done this before, so you may have to experiment. A call to your scoreboard manufacturer would likely7 be a good place to start for guidance.
I think there are several misleading statements in this video, for example that radio waves travel through air from transmitting antenna to receiving antenna. While this is true it paints a wrong picture for people who have a poor understanding of physics since air is not the transmitting medium.
Hi Zhao, We have recently optimized our learning platform which includes some highly requested features. We are happy to bring you these new improvements which will grant an even better learning experience, as a result we had to decide to no longer support the RealPars App. You can use our webpage to continue watching the video courses. Hope this helps! If you have any other questions or concerns, please do not hesitate to contact us at any time.
Hi realpars . Thanks for your great training video . Please make video about F&G( fire and gas protection system) this system used in oil and gas refinery industries as an protection system like esd system. Thank you.

🎉🎉🎉super exeleant ❤❤❤
Thank you for giving this video RealPars
You are very welcome, Mohammed!
Waiting part 2 Thanks RealPars
Thanks for explanation.
I am looking for videos that detailed differences between form 1, form 2 , form 3 .... Form 4 a,b control panels.
Thanks for educational videos...
So nice of you
Nice topic, cant wait part2,3,4...
Thank you!
How long is the maximum distance the signal can travel between the transmitter and receiver?
