A Comparative Study Of Wireless Protocols With Li-Fi Technology: A Survey
In modem days many people are using wireless communication with low power consumption, increase the data
rate and long-range communication by increasing the no of users. The wireless communication methods are transfer
information between two or more devices using the radio transmitters, receivers, remote controls and Li-Fi technology. The
Li-Fi is visible light communication (VLC) technology, developed by scientists Hass at University of Edinburg and deals with
data transmission through LED light bulb that is over IEEE 802.157.7 standards used in personal area network (PAN). They
explained as, “if LED is ON, transmit a digital data is 1 and likewise if the LED is OFF, transmit of a digital 0 or null or simply
no data transmission happens”. The Wi-Fi gives us to speed up to 150mbps as per IEEE 802.11.n and directly connected
computer to computer with the suitable network. Bluetooth devices of the application is a cordless mouse, keyboard, and
hands-free headset. UWB is the high-bandwidth multi-communication. ZigBee is reliable for wirelessly networked
monitoring and control networks. In this paper, we provide a study about the wireless communication standards, features,
behaviors and power consumption. We present in this paper about the benefit of different application and comparison of
different wireless protocols. Finally gives concussion from all the above technology.
