Advantage And Disadvantage Of Lifi Technology

1. Thanks to Wi-Fi technology, this devices can connect wirelessly and seamlessly to one’s existing broadband connection in seconds.

The network level security will form the relationships of authentication, encryption and authorization for the wireless network and its connectivity between wireless clients to the internal network. Some recommendations are:

After observing the option between Free Space Optics and Radio Frequency wireless solutions I have opted to recommend the radio frequency option because that is the option that suits the cities needs the best. Each building will have wireless Ethernet Bridge that can act as either a leaf or branch. I would suggest configuring each or at least two buildings to act as a branch allowing some form of redundancy.

WiMAX can transmit speeds up to 50km at 280mbps, and provides options for use in point to point and multipoint configurations.

2 For the wireless technology you identified, what is the standard transmission distance and transfer speed? 75 Mbps and 35 miles.

In the recent years, wireless technologies have taken a new dimension in the ways society lives. Wireless broadband is available to everyone. Whether the users are at home, driving the car, sitting in the park, and it would even work while people are a pleasure boat ride in the middle of a lake. And because of this, the need to have information at any time and be connected in all places, all the time has been satisfied.

Connecting WIFI- wireless network access convenient because no hardwire required but signal strength has limitations.

Because the long life span of LED lights, the savings in maintenance to purchase, stock and change the conventional light bulbs and significant energy savings when it comes to replacement due to the long operational life times of LED lighting.

I listen to WTOP or HLN on my way to and from work every day. The other day, I heard a snippet about AT&T working on an internet system that would provide “ultra-fast wireless broadband” internet (Padla 2016). I was excited to hear the newscast, because we had to wait almost three years before getting high speed internet,when we moved don to St Mary’s county. The thought that there are still people in our country that cannot get internet seems ridiculous.

There are scientific studies believe that the Wi-Fi does not do any damage to our human body. They said the energy per photon that the Wi-Fi emit is not strong enough. To do some estimation, we have to think about how light conveys its energy. It's moderately precise to consider light a flood of particles called photons, each with a particular measure of energy corresponding to its recurrence. We also realize that light has wave properties, for example, diffraction and impedance that can't be portrayed regarding "billiard ball" photons, yet for a moderately straightforward undertaking like this where we're not stressed over wave properties we can simply hold in the back of our psyches that these photons do have a wave nature and aren't just particles in the established way we consider particles. With that as an admonition, it's totally genuine that light does come in photons and they all have a certain

Although AT&T brought in fiber optic technology in 1979, they weren’t the first company to think of such a creative idea. The conception of interchanging data by making use of light

He is a German Professor of ‘Mobile Communication’ at University of Edinburgh, Scotland. He explained that in future a new standard of communication is required for wireless communication as current and most widely used standard Wi-Fi has some inescapable disadvantages. The term Li-Fi was also coined by him and is capable of overcoming some major bottlenecks of Wi-Fi like radio interference, bandwidth, security etc.

One of the most interesting developments in recent years in the field of telecommunication is the use of laser light to carry information over large distances. It has been proved in

Also, rental cost for the set up of the network towers is cheap which results in high network coverage.
