The PHY and MAC layers of WiFi system are defined in IEEE 802.11 standards.

WiFi network operates in different frequency bands viz.

The distance coverage of 70 meters (indoor) to 250 meters

WiFi supports different speeds and coverage rangesĪs per implemented standard in the devices (STAs, APs).Ĩ02.11a supports upto 54 Mbps, 11b upto 11 Mbps, 11n supports 72 Mbps/150 Mbps as per BW (20MHz/40MHz),Ĩ02.11ac wave-1 supports upto 1.3 Gbps (80MHz, 3 streams, 256QAM), 802.11ac wave-2 supports.

In ESS WLAN compliant STAs communicate with BSS-Basic Service Set) and infrastructure (i.e.

WiFi network operates in either of two modes viz.

As shown a WiFi AP or Router is connected to the internet using a broadband cable or with cellular network.Īll the wifi compatible mobile phones, tablets or laptops are connected with AP (or router) to obtain.

It consists of two important devices namely, a Wi-FI router or Access point(AP), Wi-Fi dongle and Wi-Fi stations.

WiFi Technologyįollowing are the features of WiFi technology as depicted in the figure-2. Refer LiFi tutorial > for more information.

It transfers data very rapidly and securely due LOS (Line of Sight) operation of.

LiFi technology is used for various applications which include street lights,.

The PHY and MAC layers of LiFi system are defined in IEEE 802.15.7-2011 standard.

LiFi system uses modulation schemes such as OOK, VPPM, CSK.

LiFi system supports three modes viz.

It uses light with wavelength ranging from 380 nm to 780 nm for data communication between LEDs and.

Here LEDs are connected with internet server via lamp driver for internet connection. LiFi dongle uses photo-detectors as shown in the figure-1. It uses LEDs at transmit ends and Photo-detectors at receive ends.LiFi transmits data using light intensity modulation.

It consists of two main components to drive the internet ,namely a LED Lamp and a Li-Fi Dongle.LiFi (Light Fidelity) works based on VLC (Visible Light Communication) principle.Let us understand them individually before we derive a brief difference between them.įollowing are the features of LiFi technology as depicted in the figure-1.

LiFi is an optical communication technology where as WiFi is a radio communication technology. Light undergoes reduced interference when compared to radio waves, and so can be used in more crammed environments. LiFi uses light as medium for data communication where as WiFi uses Electro-magnetic waves at various radio frequencies for data communication. LiFi stands for Light Fidelity and WiFi stands for Wireless Fidelity.īoth LiFi and WiFi technologies are mainly used for internet based applications. Let us go through some basic differences between LiFi and WiFi. In order to derive difference between Lifi and wifi. It covers basics of LiFi vs WiFi including their features, working operation, merits, demerits, applications etc. This page compares LiFi vs WiFi describes basic difference between LiFi and WiFi technologies. In fact, simply connecting a few of your devices to this band can help you vastly improve your overall internet experience.LiFi vs WiFi | Difference between LiFi and WiFi However, to maximize your speed, we generally recommend connecting any compatible device to the 5.0 GHz band. Technically no and many smart home devices like thermostats, garage doors, baby monitors and appliances only connect to 2.4 GHz. 5.0GHz, on the other hand, is significantly faster and because it has more channels, it's not subject to interference like 2.4GHz is. Plus, it’s more prone to interference due to having fewer channels available. 2.4GHz can reach farther distances in your home but transmits data at a slower speed. The main differences between these bands are range, speed and interference. What are the differences between 2.4 GHz and 5.0 GHz? What are Wi-Fi Bands?Įach band represents a frequency over which data transmits. Both of the GigaSpire routers automatically steer traffic to the most appropriate Wi-Fi band.
