LIFI | THE FUTURE OF INTERNET


Hi All!! What’s up?? This is Jobless guy from Jobless Productions. Wi-Fi has entered in to our lives some years now. It solves some problems that wired networks have but generate new. To overcome the problems of WIFI we have a new wireless technology called LIFI. Now what is LIFI? LIFI is bidirectional, high speed and fully networked wireless communication similar to Wi-Fi. Li-Fi is a subset of optical wireless communication (OWC) and can be a complement to RF communication (Wi-Fi or Cellular network), or a replacement in contexts of data broadcasting. How does it work? When a constant current is applied to an LED light bulb a constant stream of photons are emitted from the bulb which is observed as visible light. If the current is varied slowly the output intensity of the light dims up and down. Because LED bulbs are semi-conductor devices, and hence the optical output, can be modulated at extremely high speeds which can be detected by a photo-detector device and converted back to electrical current. The intensity modulation is imperceptible to the human eye, and thus communication is just as seamless as RF. Using this technique, high speed information can be transmitted from an LED light bulb. Why should we choose LIFI over WIFI? We have 4 Main Reason to choose LIFI over WIFI CAPACITY Data Transmission Rate is high when Compared to Wifi and also Range of the Signal is more COST LIFI is very cheap as we can use it with a small LED. Whereas Wifi as you know it needs a setup which costs more. AVAILABILITY LIFI can be used anywhere, Where light source is available whereas Wifi can be used within the WLAN Range. SECURITY Wifi can be easily hacked due to its various topologies but LIFI uses Binary Data service hence its more secured. APPLICATIONS As I said LIFI can be used anywhere, Where light source is available. It can be used Underwater communications Health sector Internet anywhere Safety and management Aviation Vehicles & Transportation And even in Toys. For New Videos Please SHARE, LIKE AND SUBSCRIBE
