Wireless: From 0G to5G: A Brief History

Our ancestors relied on primitive communications technology just a few generations back. It’s all relative. The major innovation was Wired Telegraphy, which crisscrossed the United States.
The advent of wireless telegraphy, which is radio, made it possible to have a conversation without using cables. The range of services has been expanded by the many improvements made to radio communications over the years. The fifth-generation mobile telephony, also known as 5G, is the latest invention that will thrill and amaze users.
A Brief History of Wireless
It is possible to believe that the first use of telecommunications occurred in the midst of all history. However, the first use of water telegraphy by Greek soldiers was 400 B.C. It was easy. The process was simple. Each barrel contained a water spigot and a stick with written symbols at its center. The first signalman would open the water spigot to send a battle message. He would signal the distant soldier to open his. The signalman would shut off the spigot when the water level reached the correct symbol on the stick and flag the other signalman. This was an ancient form of telecommunications.
The French used semaphore to implement telecommunications in a more recent way. They built semaphore towers throughout the country in the 1700s. Each tower was a short distance from the nearest tower but still within easy reach. A French communications technician could transmit messages to the next tower by using mechanically controlled flags. This method allows a message to be sent quickly across the country.

Guglielmo Markini was the first to use long-distance radio communication, which is the basis of all modern mobile telephony. The electromagnetic spectrum, which includes radio waves at frequencies ranging between 30 Hz and 300 GHz, is at the heart of all this.
From 0G to 5″
Many technologies that mobile telephony would use were in use long before the invention of mobile phones. Police and firefighters were already using push-to-talk systems (PTT). Radio towers that could transmit news and entertainment over great distances were powerful. AT&T had a Mobile Telephone Service (MTS), which was available as far back as 1949. Later, it introduced the Improved Mobile Telephone Service(IMTS) in 1965. These mobile network predecessors have been given the name “0G” by some people.
It was not as obvious as the birth of 1G. In 1979, Japan’s Nippon Telegraph and Telephone (NTT), introduced the first generation (1G), of mobile telephony. Other carriers followed quickly. In 1981, Nordic Mobile Telephone implemented 1G. Standards such as Advance Mobile Phone System by Bell Labs (AMPS), in 1982, and C450 in Germany in 1983 were widely spread.
In Finland, the second-generation (2G), was launched in 1991. It was based upon the GSM standard and included text messaging, known as short message service (SMS), along with other services. The 2g standard was later extended to include general packet radio service (GPRS), and enhanced data rates for GSM Evolution(EDGE).
Things got interesting with the introduction of 3G. The internet boom in the late 1990s created a demand that users use their mobile phones to access the internet. In 1998, the 3rd Generation Partnership Project (3GPP), was established to develop protocols and standards in 3G. It was a collaborative effort of organizations from all over the globe. It was the result of the introduction of robust technologies such as Wideband Code Division Multiple Access, (WCDMA), and High Speed Packet Access, (HSPA), which made web access possible at high speeds and with large capacities.
4G, also known as Long-term Evolution or LTE, was a complete restructuring.
