Evolution of the phone: the journey from the first phone to the VoIP phone

No one is ignorant of the fact that the first telephone was invented by Alexander Graham Bell in March 1876. That is where the modern-day field of telecommunications has its roots.

This invention might not have attracted much attention, as Bell’s weak expectations said, but it was the Centennial Exposition in Philadelphia where the emperor of Brazil, Dom Pedro de Alcántara, became aware of this interesting man-made invention. . He couldn’t help but be surprised by Bell’s profound creativity, which was reflected in his creation, the telephone.

In the early days, the phone was only seen as a luxury of life rather than a commodity. It only gained more popularity as an essential means of communication at the time that many corporate and government offices started using it.

During the 1880s, when metallic circuits were introduced, they took over long-distance communications. However, for a decade, its use remained restricted to a certain class that could afford the high call charges. Until in the 1890s, with the rise of the partisan line, it became convenient for people living in particular rural areas to divide the cost of the line used by many.

Before 1891, calls were made by exchange operators, but until a new direct dialing system. Then there he was putting the telephone to its best use in 1927, when the first transatlantic telephone call was made with the help of radio waves. It was during the times of World War I and World War II that the phone underwent a significant period of development, all thanks to huge expenditures made by the Department of Defense to ensure more secure communication. This series of advancements also led to the creation of the first mobile phone system, which easily connected mobile vehicles to phones using radio waves.

In the 1960s, transatlantic cables were introduced to facilitate international call dialing.

However, the biggest changes in the history of telephones occurred in 1962, when the first TelStar telephone satellite was launched. Telstar was a joint business venture between Bell and NASA to offer a more advanced form of communication. This paved the way for satellites rotating within geosynchronous orbit to be used to make long-distance calls directly without relying on cable lines, not to mention suffering due to repeated cable damage and repair pain.

Fiber optic cables were first introduced in 1977. In the mid-1980s, fiber optic cable took precedence over other modes of telephone transmission because it could facilitate a greater number of calls with less interference, compared to its methods. predecessors. It could transmit information more quickly to more distant areas and strongly withstood any mishap, particularly lightning strikes. Ultimately, it offered a number of advantages and was safer than other modes. Due to the benefits, these fiber optic cables also began to be used for computers.

After the US government relaxed regulations on phone service, AT&T rallied to face stiff competition from MCI, Sprint and many other local companies. This road paved for fiber optic lines to be widely used in all industries, it even began to be used for natural gas pipelines and railways.

It was in 1973 that Dr. Martin Cooper of the Motorola Corporation created the first cell phone call using a portable phone, namely the Dyna-Tac. After running a successful audition, he was featured on New York Public. It was in 1977 when the cell phone became popular with the people. The models initially presented seemed a bit larger and commonly used by those who were used to keeping in touch using the two-way radio communication mode. At that time, one couldn’t imagine that it was going to be used by everyone. Cell phones were operated with small “cells” for the range of service, to increase the ease of handling more calls. Cell phones made it possible to handle a greater number of calls at the same time in an area.

However, initially, primary cellular services used rather an analog technology system, running at 800 megahertz incessantly. Over time, the industry increased the standard to 1850 MHz with PCS. In 1988, a committee, namely the Cellular Technology Industry Association, was formed to formulate guidelines and establish regulations for cellular service providers and functioned for the development and growth of the cellular phone industry. Today, we have approximately more than 60 million cell phone customers, an overwhelmingly huge number for a service that began operating commercially just thirty years ago.

Today, we use digital cell phones / mobiles, rather than analog phones. Digital technology transfers data in the form of “pulses”. The benefit of digital signals is that they are transmitted much more securely compared to their analog competitors, and they provide more efficient bandwidth and better sound quality. You can even share videos and photos while browsing the Internet. All at the same time integrated into your phones.

However, in digital technology there is a little problem with coverage. For example, due to three different technologies a cell phone uses, in case you are using a TDMA (Time Division Multiple Access) system but you move into an area that caters for CDMA (Time Division Multiple Access) digital coverage. code), then you may have to face technological problems.

There is a perfect solution for it and the analog-digital technology coupled with the one that cell phone providers are changing. In this way, you can get excellent coverage for all types of communication, with high speed and unmatched quality.

Talking about the first “conference call” that was used could be the time when partial lines were first introduced in the early days of the telephone. Although, at that time, the only benefit that people could look for in the partial lines was the economic factor, there was the problem that several people in different locations could capture and speak by the same simultaneously, which generated a situation of listening and zero element of privacy.

The idea of ​​calling a number of people, which initially stemmed from partial lines, was revived again but this time in a better and more private package. It was time constrained and only accessible in times of need.

Following this notion, companies around the world began to offer services, which coordinated a facility for conference calls for companies, granting them fixed rates, monthly fees or based on the number of calls made. This was fruitful as it saved travel expenses and other calling expenses. They provided a trained operator to allow connections between each participant on a dedicated line. In this way, a group of people could easily communicate with each other at the same time. Service providers offered affordable rates to their clients.

Earlier, many phone manufacturing companies, such as Polycom, AT&T, and Panasonic, developed office phone systems that allowed office users to invite a customer, put them on hold, and then call someone else. This helped create a multi-connection setup so that callers could easily reach more than two people at a time to discuss important business.

The Internet has arrived, which turns out to be the best communication medium ever created throughout the history of mankind. The Internet accelerated competition among telephone service providers, particularly challenging the installation of audio conferencing and the cost of long distance calls. However, they have reduced their calling costs to a greater extent, however, the unbeatable broadband phone or Internet phone is becoming everyone’s favorite, surpassing its competitor, the traditional phone, because it is much cheaper and affordable.

Voip, which stands for “Voice over Internet Protocol,” is now the most popular means of communication because it charges only per call, with no regulatory taxes or hidden charges, like the fees charged by traditional phone companies. VoIP phones or broadband phones use high speed internet to work and allow you to enjoy the same quality of service that traditional phones offer. Not only can you make calls with your voip phone, but the high speed internet phone also allows you to enjoy high speed data transfer services such as data sharing, audio conferencing and video conferencing. With voip, you are guaranteed to save a lot on your calling and communication needs.

VoIP offers you audio conferencing facilities to network with multiple groups or parties, regardless of their geographic locations. This allows clients to connect with their clients around the world and host a virtual meeting online. Today, VoIP calling solutions are being provided by Axvoice, Vonage, 8×8, Voxwire, Packet 8, TTCGlobalTalk and VoiceCafe, among many others, providing excellent quality of service.
