2. Brief transmission of information over a distance
without requiring wires or any other electrical
conductors.
Wireless communication is one of the important
mediums of transmission of data or information to
other devices through the air, without requiring any
cables, by using electromagnetic waves like radio
frequencies, infrared, satellite, etc.

4. Bluetooth stands for Short-range transmission of digital
voice and data. Bluetooth is a short range and low
power wireless technology originally developed for
exchanging data over short distances from fixed and
mobile devices, creating personal area network.
Range of Connection : 10 m – 100 m.
Supports data rate of : 1Mb/s.
Bluetooth

5. The NFC (Near field communication) is a data transfer
technique and is the type of the wireless communication with
short range. The data is transferred in the form of beam by
touching the two things together. A single wave or beam
helps to transfer the data between two devices within the
range of 4 centimeter and Based on RFID technology at 13.56
MHz .
Possible transfer rates are 106, 212, 424 kbps.
Near Field Communication(NFC)

6.  Wi-Fi or wireless fidelity, allows you to access the internet
while on the move; you can remain online while moving
from one area to another in a wireless mode.
 Wi-Fi enabled computers send and receive data indoors
and out anywhere within the range of a base station.
 Its just as fast as cable modem connection.
 Wi-Fi is a generic term that refers to the IEEE 802.11
communications standard for wireless local area
networks(WLANs)

7.  The Global Positioning System (GPS) is a satellite-based Navigation
system developed and operated by the US Department of
Defense.
 GPS is the shortened form of NAVSTAR GPS. This is an acronym
for Navigation System with Time And Ranging Global Positioning
System.
 GPS uses constellation of 24 satellites to determine the accurate
three dimensional position of the user on the earth.
 GPS was originally designed for military use at any time anywhere
on the surface of the earth but soon after proposals it is made
available to civilian users also.

8.  RADAR(Radio Detection and Ranging) is a object
detection system that uses radio waves to determine the
range, angle or velocity of object.
 A radar system consist of a transmitter producing
electromagnetic waves in the radio or the microwave
domain , a transmitting antenna , a receiving antenna and a
receiver and processor to determine the properties of
object.
 Radar was developed secretly for military use by several
notation in the period before and during world war 2.
Radar Communication

9.  A cordless telephone is a portable telephone that
uses radio waves, rather than a wire, to communicate
with a base station that is connected to a standard
landline.
Cordless Telephones or Mobiles

10. 1G
 Introduced in the early 1980s and
 completed in early 1990s.
 Analog signals with the speed up to 2.4kbps
 Voice was main traffic
Wireless Generations

11.  Late 1980s and finished in 2000s
 Digital signal with up to 64kbps
 Voice transmission and SMS
2G

12.  Late 1990s to late 2000s
 Transmission speed from 125kbps to 2Mbps
 Based on either circuit switching or packet switching
3G

13.  Starting from late 2000
 Transmission speed from 100Mbps to 1Gbps
 Only packet switched networks
4G

14.  5G and 6G
 Massive MIMO Antennas
 Li-Fi
 Wireless charging
Up Coming Wireless Technologies

15.  Massive multiple input, multiple output (MIMO)
antennas will be an important technology for
enabling 5G and eventually 6G networks.
Instead of having just a few antennas at each
end of a link, a Massive MIMO system has a
much larger number of antennas. This enables
multiple signals to travel over the same radio
channel at the same time, meaning that the
capacity of the system is much higher.
Massive MIMO Antennas

16.  As compared to previous generations of networks, this new
generation of wireless tech is expected to offer more speed, lower
latency and the ability to connect more devices, such as IoT devices.
Speeds of one Gigabit per second (Gbps) are expected to be typical,
but it could potentially get as fast as 10 Gbps.
 5G will run on two different kinds of frequencies. Low-frequency 5G
will use existing Wi-Fi and cellular bands and get its speed from
more flexible encoding and larger channel sizes. Other types of 5G
will run at frequencies as high as 28 to 39 Gigahertz (GHz), which
aren’t currently heavily used.
5G

17.  The 6G network, ComSenTer says, will operate at
frequencies of 100 GHz to 1 terahertz (THz) and offer
speeds of up to 100 Gbps with very low latency.
According to the researchers, 6G will be able to
handle hundreds or even thousands of simultaneous
connections. Overall, the system should be able to
offer more capacity with lower power requirements.
6G

18.  Another exciting future wireless technology is Li-Fi,
which is similar to Wi-Fi but uses visible light waves
instead of radio waves to send data.
 Using Li-Fi would be advantageous for many reasons.
It offers increased sped and improved security. In lab
tests, it has reached speeds of 224 Gbps.
Li-Fi

19.  In the future, we will be able to charge our phones
while they are in our pockets. Large main power
sources could be placed in discrete places, such as in
the ceiling, and charge multiple devices at once.
Several companies are working on these types of
technologies. A company called Energous has
developed a product called Watt Up that features a
small central power source and can charge
devices from up to 15 feet away.
