It is with great pleasure that I share with all of you my humble and most sincere homage to Nikola Tesla, the genius and pioneer in what today is our job and passion, wireless communications.
This week of July 10, we are celebrating the 155th anniversary of the birth of Tesla, one of the most important inventors in history. Tesla mastered disciplines such as physics, mathematics and electricity and is considered the father of the alternating current and founder of the electrical industry. His most famous invention was the eponymous Tesla coil, which was a source of electromagnetic energy in early wireless telegraphy systems up until the 1920s.
Among his most important inventions were the radio, the coils for the alternating current electrical generator, the (electrical) induction motor, the sparking bulb, the alternator and the remote control. However, few of these machines were acknowledged as invented by Tesla. In spite of having an amazing mind, being a visionary as well as an intelligent man as few are, he was a mysterious and obscure character, controversial and incapable of obtaining any benefit from his inventions and even saw another man receive the Nobel Prize for one of his own inventions.
People associated him with strange experiments, secret weapons and unrealizable theories that exceeded the utopian and even bordered on insanity. Besides electromagnetism and electrical engineering, Tesla’s work comprises multiple disciplines such as robotics, ballistics, mechanics, computer science and nuclear and theoretical physics, which allowed him to even question some of Albert Einstein’s theories
Although Tesla was not well known, his practical and functional inventions are the source of technologically advanced civilization in such an elemental way that it was said Tesla was the one who invented the 20th century.
Brief Nikola Tesla biography
Nikola Tesla (July 10, 1856 to January 7, 1943) born in Similjan, what at that time was the Austro-Hungarian Empire, which today is part of Croatia. A genius since his early years as a student who was passionate about mathematics and science, he was able to memorize complete books and make complex mathematical calculations to the embarrassment of his professors.
His father, who was an Orthodox pastor, pushed him to follow his religious vocation, but Tesla was more motivated by his mother’s instinct of development, which led her to invent gadgets such as the mechanical egg mixer to help her with house chores. Tesla studied mechanical and electrical engineering in Austria and physics in what would become Czechoslovakia and worked in several electricity and telephone companies throughout Europe.
It is important that I highlight an extra aspect related to free energy. Tesla was a genius who thought that energy should be free of charge, which is why many of his inventions were never to acquire this benefit. Unfortunately, his viewpoint made many important men of the day into his mortal enemies, such as Thomas Alva Edison and George Westinghouse, among others.
Tesla was a great human being with a unique strength of character—to such an extent that he endured with great stoicism when Guglielmo Marconi obtained the 1909 Nobel Prize in Physics using Tesla’s radio patents.
Dear colleagues, as a last tribute to Tesla, let me ask you to take a moment of your time to surf the web and read the great amount of information available about him. Enjoy it and share it, and let’s make that our best tribute to this great inventor who left us not only his teachings about technology but also a message of humbleness.
Thanks for sharing this homage.

In response to the recent FCC docket 10-153, many stakeholders proposed relaxing antennas requirements so as to allow the use of smaller antennas in certain circumstances. This is an increasingly important issue as tower rental costs can be as high as 62 percent of the total cost of ownership for a microwave solutions link. As these costs are directly related to antenna size, reducing antenna size leads to a significant reduction in the cost of ownership for microwave equipment links.
The Fixed Wireless Communications Coalition (FWCC), of which Aviat Networks is a major contributor, proposed a possible compromise that would leave Category A standards unchanged while relaxing Category B standards. The latter are less demanding than Category A, and after some further easing, might allow significantly smaller antennas. The rules should permit the use of these smaller antennas where congestion is not a problem, and require upgrades to better antennas where necessary.
A further detailed proposal from Comsearch proposed a new antenna category known as B2, which would lead to a reduction in antenna size of up to 50 percent in some frequency bands. This would be a significant cost saving for link operators.
At the present time, the industry is waiting for the FCC to deliberate on the responses to its 10-153 docket, including those on reducing antenna size.
