The electromagnetic field is a force where both electronic and magnetic components. These compel the motion of an electric charge that contains a definite amount of electromagnetic energy. Electromagnetism was discovered by Hans Christian Oersted in 1820. He explained when he was teaching at the Albany Academy in New York that an electrical prevailing in a wire from a battery caused a nearby compass needle to obviate. In the late 1880s, Heinrich Hertz showed evidence of radio waves. Thus, the unit of frequency, cycle per second, was named “hertz” as an acknowledgment for his patent.
Sixteen years later, radio bases were successfully created by Marconi in 1896. He was awarded because of his discovery by the British patent 12039. Marconi’s creation was officially established on the Isle of Wight, England last 1897. The triumph in his production of radio bases enhanced the transmission impulses and signals for telephones.
Now, these radio bases are utilized for sending messages and calls made by mobile devices, personal computers, laptops, and electronic tablets as well. These inventions became a massive help in the global economy’s progression throughout the centuries up until the current time.
Authorities even legalized policies such as Public Records Laws in the public sector, Financial Industry Regulatory Authority, Markets in Financial Directive (EU), and the Securities and Exchange Commission (US) to monitor text messaging and phone calls.
The reason behind the implementation of voice calls, video calls, and text message monitoring is to provide authenticity towards the sectors and firms, plus a testimony when investigating an illegal transaction.
Despite the beauty of mobile archiving, there are still a few downfalls in this implementation. Be knowledgeable about all those pitfalls on the infographic below brought to you by TeleMessage:
