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.
