LIGHT- FIDELITY

Light Fidelity or li-fi is a Visible Light Communications (VLC) system running wireless communications travelling at very high speeds.

The objective of LI-FI is to transfer data through visible light. Since the bandwidth of visible light is 10,000 times more than Radio waves, more data can be transferred through light at short period of time.
Li-Fi uses common household LED (light emitting diodes) lightbulbs to enable data transfer, boasting speeds of up to 224 gigabits per second.
Visible light communication (VLC) eliminates the risk of some disease caused by the Radio waves due to long period exposure. This protocol can be adapted where Radio waves are restricted, such as airplanes, hospitals, and in some research facilities. Researchers reached bit rate of 224 GB/s which is 100s of times faster than our average WI-FI connection at home or office. lifi

INTERNET OF THINGS

RAIN RFID is a passive (battery-free) wireless technology system that connects billions of everyday items to the Internet, enabling businesses and consumers to identify, locate, authenticate and engage each item. RAIN RFID is used in a wide variety of applications, including inventory management, patient safety, asset tracking and item authentication. RAIN is the fastest growing segment of the RFID market and uses a single, global standard: UHF Gen 2 (ISO/IEC 18000-63). RAIN has connected over 20 billion items to date. By providing internet connectivity to and real time information about everyday items such as apparel, medical supplies, automobile parts, food and more, RAIN RFID enables the true Internet of Things.download

EMERGING TECHNOLOGIES-RFID

RFID or Radio-Frequency Identification is modern technology that reduces the
complicacy of our daily life. RFID is basically a tiny electronic device that consists of
a small chip and an antenna. The chip typically is capable of carrying few bytes of
data or less.
The RFID device function the same purpose as a bar code or a magnetic strip on the
back of a credit card or ATM card; it allows a unique identifier for that object. And,
just as a bar code or magnetic strip must be scanned to get the information, the
RFID device must be scanned to retrieve the identifying informationsystem_eng_resize
