Wireless communication is a method of
transmitting information from one point to other ,
without using any connection like wires, cables or
any physical medium.
Generally in a communication system,
information is transmitted from transmitter to
receiver that are placed over a limited distance.

IR wireless is the use of wireless technology
in devices or systems that convey data
through infrared radiation.
Infrared is electromagnetic energy at a
wavelength or wavelengths some what
longer than those of red light.

WIRELESS TECHNOLOGIES FOR
FUTURE MOBILE DEVICES AND
Wi-fi(2.4 GHZ and 5GHZ)
wiGig is an advanced version of wi-fi( operates 60
Li-Fi(speed can’t be detected by human eyes,
specific light sensors can detect these signals)
NFC(near field communication technology)
5G NR Millimeter waves
The swift development of wireless has enabled so
many parallel technologies, increased productivity
and even saved countless lives.
The future for wireless looks set to include even
more applications which can give humans an
Another positive of this growth is that wireless
technology has gotten really cheap which means
that more people have access to it.
Wireless innovations have made the world a much
smaller place .
