LIFI LIFI Wireless technology Why do we need an alternate technology? • CAPACITY • EFFICIENCY • AVAILABILITY • SECURITY WORKING DISADVANTAGES of LIFI • LIFI signals cannot penetrate the walls. So the person needs wired bulb always in that room also. • It only works if there is direct line of sight between source and receiver. • For Broadcasting it is difficult to uplink. APPLICATIONS of LIFI • Underwater communications: Radio waves cannot be used under water because of the reason waves are strongly absorbed by sea water within feet of their transmission and this renders it unusable underwater but LIFI is suitable for underwater communication • Health Field: WIFI is not safe to be used in hospitals and other various health Field centers because it penetrates human body. LIFI can be implemented and well suit in this sector. • Internet can be used anywhere: street lamps, light of vehicles can be used to access internet anywhere in footpaths, roads, malls, anywhere where light source is available. • Think about Safety and management: It can be used to update traffic information also and at every instant and it will be easy for traffic police to deal with traffic and catch the one who breaks the rule.
