Telecommunication history
Human beings have taken interesting initiatives to communicate with people who were far away from time immemorial—for example, sending messages to others by lighting fires on a hill or through birds. Gradually, with the postal system’s appearance, people used letters to communicate with each other. A little while later, with the telephone’s advent, a significant change in telecommunications took place. Through these technologies, people could easily talk to each other live at any time. After a while, with the invention of the radio and television and then the Internet, along with voice and video calls, distance education was also raised. The relentless advancement of telecommunications technology has now reached video conferencing, and of course, it will not be the endpoint.

Technology and the global telecommunication
With the advent of new means of communication, the human way of life, including work and education, changed dramatically. Using these new methods, individuals could expand their professional and financial capabilities from local geography to a national and global scope in a short time and at a low cost. The process began with the telephone and telegraph and then reached the everyday use of radio and television in offices and homes. Telecommunications culminated with the birth of the Internet. With the help of these voice and video calling tools – including video conferencing software – human society could provide the education process, with a quality similar to face-to-face training, in remote or deprived areas virtually.
Internet and related applications
With the global expansion of the Internet and the global village’s birth, educational programs and communications took on a new form. Nowadays, many business meetings, gatherings, screenings of movies and theaters, economic activities such as purchasing goods and services, and even support services are online. The new coronavirus has also fueled this situation, making virtual activities more pervasive through various software, including video conferencing.
Elite people, who can not physically participate in the world’s scientific centers for various reasons, such as physical disabilities or long distances, or even lack of financial ability, can provide their educational services to people worldwide or participate in appropriate training courses.
There are currently various Internet telecommunications software and video conferencing applications based on different operating systems, such as iOS, Android, and Windows.
This article introduces and reviews some of this software.
Imo messenger video conferencing app
Imo is a simple application for conducting virtual conversations and video conferencing. This app is available for free on different operating systems, including iOS.
One of the Emo’s advantages is that it works well with low-speed internet, a feature not found in many competing messengers.
Using this software, you can set up a conference room and hold video conferences with a maximum of 20 people. Sending high-quality documents and videos is another emo feature.
Skype video conferencing application
Skype is one of the best video conferencing software for making video calls on all platforms. The capacity to use Skype on different operating systems is one of the most valuable advantages of Skype, making it one of the best options for making cross-platform video calls.
Using this software, you can simultaneously hold a video conference with up to 25 people. The app also supports text chat. You can also sync your Google and Microsoft account with Skype.
However, Skype keeps audios, videos, and other documents for up to 30 days, after which time the files will not be accessible. This is one of the defects of this software that hinders it from being a reliable messenger. That’s why Skype is more suitable for video conferencing than sending and storing information.
WhatsApp is one of the most widely used applications in the world. This software is one of the few applications with more than one billion active users. WhatsApp started as a text chat service and underwent massive changes after Facebook bought the messengers.
The app currently supports voice and video calling in addition to many other features. Video calling works well on WhatsApp, and you probably won’t have any problems using it.
However, the number of people who can participate in your video conference is not more than 8. This number was limited to four people before, but recently in the new version of this application has reached eight.
WhatsApp uses signal technology. In recent weeks, the app has asked its users to agree to share their information with Facebook. This information includes location, phone numbers, etc. This new WhatsApp term of using caused many reactions worldwide and made many users migrate to other messengers. This has caused WhatsApp to delay implementing its new terms of use.
One of the software that many WhatsApp immigrants moved to is Signal, which we will introduce more here.
Google Dou video conferencing app
Google Dou is Google’s achievement in video calling applications and has a similar approach to the FaceTime application. This application allows video chat between 8 people. Furthermore, users can see a preview of themselves before answering the video call.

FaceTime
FaceTime is an Apple video calling application that only runs on its devices. It is available for mobile phones and Mac OS Snow Leopard. FaceTime runs on any IOS device with a front-facing camera and any Mac computer with a camera.
FaceTime lets you easily make video calls to other FaceTime users. The system uses a front-facing digital camera on compatible devices to display the caller and the recipient’s images.
FaceTime calls can be made between FaceTime compatible devices, such as the iPhone 8 to iPhone X, from Mac to iPhone, or from Apple to iPod Touch. The devices do not need to be of the same model or type to use this software.
Unlike some other video apps, FaceTime only supports one-on-one calls and does not support group calls and video conferencing.
On January 29, 2019, a report published on Facebook claimed a security flaw: The caller could receive the other party’s voice and video even before the other party answered the phone. Following this report, Apple also confirmed this security flaw and temporarily disabled the application on iPhones.
