In todays world technology is growing like your hair, And U cant
even imagine that in future we will be equiped with powerfull smartphones ,
smart LEDs, with almost all types of sensor and navigation systems
In UK scientists have
achieved record in data transmission speeds of upto 10 gigabits per second and
it is almost more than 250
times faster than 'superfast' broadband using LED light bulbs.
Using a digital modulation technique called Orthogonal
Frequency Divisional Multiplexing (OFDM), researchers enabled micro-LED light
bulbs to handle millions of changes in light intensity per second, effectively
behaving like an extremely fast on/off switch.
This OFDM technique allows
large chunks of binary data that is a
series of ones and zeros - to be transmitted at high speed.
.
This upcoming
technology will be cheaper and more energy-efficient than existing wireless
radio system.
