All You Need To Know About Optical Beaming Technique

We all are acquainted with wireless technology. We have wi-fi and internet dongles in our day-to-day lives. Our lives are twirled around wireless technology, most of which we are not even aware of. 

Most of us use wireless technology to either charge devices like phones, watches, earpods, etc. However, these still require a pad or support to get the charging done. 

Though this technology is very powerful, the range is a major hurdle. What if I say that the new wireless technology does not have range issues? It works on a new technology that uses the laser to transmit power rather than electromagnetic waves. 

Yes, you have read it right. In a proof of concept project, Ericson and PowerLight Technologies have developed a new technique called optical beaming to transmit power to portable 5G stations. This technology uses the laser to transmit power and not electromagnetic waves. 

Let us understand this technology in detail. 

 

What is Optical Beaming Technique?

Like we need charging pads for wireless chargers, but have you thought about beaming electricity for long distances?

Well, scientists are working on a technology that can charge devices anywhere within the room. But, PowerLight has been working on this for years. It has recently come up with a proof of concept of optical beaming in partnership with telecommunication giant Ericsson. 

This technology is made up of two components:  

  • Transmitter 
  • Receiver 

These can be potentially thousands of meters apart. 

 

 

Optical Beaming Technique

 

How does Optical Beaming Technique Function?

Like Tesla Coil, this system does not send electricity directly. Then how does this work? 

  • The electricity at the transmitter end is used to produce a powerful beam of light which is sent to the receiver. 
  • The receiver catches it using a photovoltaic array. 
  • The photovoltaic array converts the incoming photons back into electricity. 
  • This is how the connected device gets power. 

This sounds exciting! But the entire process involves a risk of high beam light being exposed in the open air. To avoid any accident or casualties, the below measures are taken. 

  • The beam is surrounded by a wider cylinder of sensors. 
  • When these sensors sense something approaching, they turn off the beam within a millisecond. 
  • This reaction is so quick that even a fleet of birds cannot be affected by the beam and vice versa. 

The question then arises, what in case of any long-term disruptions? For long-term disruptions, the receiver is equipped with a battery backup that helps with the power supply.

What is the PowerLight - Ericsson Deal?

PowerLight was powering one of the 5G stations of Ericsson. This station was not connected to any other power source. PowerLight delivered 480 watts over a distance of 300m. 

Interestingly, the team working on this claims that 1000 watts of power can be supplied to a distance of 1 km with this technology. 

 

Benefits of Optimal Beaming Technology

  • With the Optimal Veaming Technology, the 5G stations can be more portable. 
  • They can be rolled out to temporary locations like festivals and events. 
  • They can be used to charge electric vehicles. 
  • Make the power grid more adjustable. 
  • They can also be used in space missions. 

 

Conclusion 

Wireless technology is the future. This is a boon for every gadget that needs a power backup for functioning, from cell phones to electric vehicles. Notably, not just PowerLight, but even startups from different parts of the world are trying to make progress in the field of long-distance power transmission.

Get $5,500 USD every day, for six months! See how it works. What'sApp : +393512615163 I want to testify about Dark Web blank atm cards which can withdraw money from any atm machines around the world. I was very poor before and have no job. I saw so much testimony about how Dark Web hackers send them the atm blank card and use it to collect money in any atm machine and become rich. Email : carolblankatmcard@gmail.com Hangout : carolblankatmcard@gmail.com What'sApp : +393512615163 They also sent me the blank atm card. I have used it to get 90,000 dollars. withdraw the maximum of 5,000 USD daily. The Dark Web is giving out cards just to help the poor.

I'm so happy to share this with you that can read / see this now. When I started trading binary and forex a few months ago, I really didn't have the necessary tools to trade and I lost a lot until I met Pablo Martinez who taught me all about market psychology as he managed my account for me. Today I am grateful to him for his great offer and help because it really changed my financial situation with an investment capital of $1500 and now I'm earning around $35,500 - $30,000 profits per week. Here is his WhatsApp no: +44 7520 636249 or his email address: pm7234029@gmail.com Https://www.facebook.com/PM-Fast-Trade-104912912155335/

What a great relief for my dad's business pages on Facebook / Instagram accounts after it got compromised by a yet to be identified strange person ,all of a sudden he got locked out of his personal and vital business pages. As the only admin on several groups that he runs for real estates in Italy with over 15k members . He is completely at a loss here because he can't make a new profile because of hundreds of important business and personal contacts on his pages that are very critical to his online businesses and websites. Thanks to (fixurworries ATdoctor DOT com) who finally retrieved his Facebook/Instagram accounts within 48 hours.
