Did you know whats is Wireless communication ?

Wireless communications is the transmission of voice and data without cable or wires. In place of a physical connection, data travels through electromagnetic signals broadcast from sending facilities to intermediate and end-user devices.

The first wireless transmitters went on the air in the early 20th century using radiotelegraphy, which is radio communication using Morse code or other coded signals. Later, as modulation made it possible to transmit voice and music wirelessly, the medium became known as radio. Wireless transmitters use electromagnetic waves to carry voice, data, video or signals over a communication path.

The groundwork for modern wireless networking was laid in the early 1970s with the launch of ALOHAnet in Hawaii. The network, technically a wide area network (WAN), relied on ultra-high frequency signals to broadcast data among the islands. The technology underpinning ALOHAnet helped fuel the creation of Ethernet in 1973 and played an important role in the development of 802.11, the first wireless standard.

Fun way to learn wireless communication

Circuitmess Chatter is a free, private, security-first texting device.

Unlike your regular phone, this device does not need a cellular network or a SIM card to work because it creates its own wireless network and communicates with other Chatter devices you’ve paired it with.


It uses the so-called “LoRa” low-power wide-area network technology in order to send text messages, emojis, memes, and GIFs.

Chatter uses a publicly-available set of frequencies that are allocated for use cases like this one.


The messages you send to other Chatter devices are encrypted and are not passing through an internet service provider so you can share as many secrets as you want with your friends (maybe we should’ve programmed a pinky swear button).

This device is not a replacement for your regular phone and has the range of an average walkie talkie – around 1 – 7km depending on the surrounding area (concrete buildings and basements are usually not a good spot for getting a good range with this thing) but it can prove useful in certain situations.

The main purpose of Chatter is education and showing people that you can communicate free and remotely without big corporations and the internet.


What you’ll learn:

  • How to assemble your very own private texting machine
  • What privacy means in the year 2022 and how you can digitally communicate without using the internet
  • How LoRa works
  • How Chatter encrypts/decrypts messages and pairs with other Chatters
  • How to code and load custom apps onto your Chatter

Fun facts :

Guglielmo Giovanni Maria Marconi was an Italian inventor and electrical engineer who was one of the pioneers of radio and electronic industry.

Wireless telegraphy is a form of communication that uses radio waves to transmit data. Marconi’s invention of a practical radio wave-based wireless telegraph system was a significant milestone in the development of wireless communication.

Guglielmo Marconi sent the world’s first radio message across open water on May 13. 1897. He sent the message while visiting a seaside resort in Somerset. The message was transmitted from Lavernock Point on the South Wales coast (overlooking the Bristol Channel) to Flat Holm island 3 miles (4.8km) away.
