Now the technology has made new innovation in the field of
Networking.
That is Li-Fi
We are having a question in our mind .
Does Li-Fi replace to Wi-Fi in upcoming days?
We should know about the Li-Fi :
Li-Fi is wireless communication technology as we have use wi-fi .
Li-Fi use to utilize light to transmit data and and position between
the peripheral devices and computers.
Li-Fi has been tested in real world .Does
we know the benefits of Li-Fi ?
Advantages of LiFi:
1. Speed: LiFi Provides
speeds that is 100 times more faster to Wifi.That help you to transfer data with so fast speed .
2. Efficiency: LiFi is much more
efficient when it comes to cost and power consumption. LiFi uses LED bulb for
making communication these bulbs can double up as regular lighting for a
household reducing power consumption of a LiFi network and making it far
efficient than existing technologies alongside not requiring any additional
hardware for implementation would reduce the cost of setting up LiFi.
3. Availability: Due to the use of
LED bulbs, LiFi can be made available everywhere by replacing traditional LED
bulbs with LiFi compatible bulbs.
4. Security: Since LiFi makes
use of visible light spectrum, it cannot penetrate through optically opaque
objects like walls making it difficult for unauthorised access unlike present
WiFi which could be accessed from beyond walls and making it vulnerable to
unauthorised access.
Disadvantages of LiFi:
1. Special Hardware
Needs: It
needs specialised hardware for implementation which isn't currently available
on a large scale.
2. Technological
Advancements: The
current technology must be upgraded in order for LiFi to be implemented on a
large scale and for common public to use it.
3. Cost Factor: Since the
technology is new, there has been a huge amount invested in its R&D and
hence LiFi is very expensive.
4. Uplink Issues: LiFi has
demonstrated extremely high downlink speeds. There has never been any mention
regarding the uplink and any clarity on how it is being implemented.
5. Interference: LiFi signals are
prone to interference from everyday lightings such as sunlight, common
household lighting etc due to the use of visible light for its transmission.
6. Limited Range: The range of LiFi
is limited by two major factors: Dispersion of light and inability of light to
penetrate optically opaque objects (like walls of a room).
7. Use of WiFi: The widespread use
of WiFi is a major factor preventing the use of LiFi. The limitations of LiFi
makes it a difficult task to replace conventional WiFi networks.
