    What is wireless communication?

    • In layman language it is
    communication in which information
    is transferred between two or more
    points without any wire.
    Modes of wireless communication!
    • Bluetooth

    • NFC (Near Field Communication)

    • Wifi

    • Lifi
    What is Bluetooth?
    • Bluetooth is a method for data
    communication that used short
    range radio links to replace cables
    between computers and their
    connected units.
    • Named on – Danish king harald
    Bluetooth
    • Developed in Scandinavia.
    How does Bluetooth works?
    • Bluetooth networking transmits data via low-
    power radio waves. It communicates on a
    frequency of 2.45 gigahertz.
    •  Bluetooth doesn't require line of sight between
    communicating devices.
    • Bluetooth can connect up to eight
    devices simultaneously.
    • Bluetooth uses a technique called spread-
    spectrum frequency hopping 
    Bluetooth is essentially a networking standard that works at two
    levels:

    • It provides agreement at the physical level --


    Bluetooth is a radio-frequency standard.
    • It provides agreement at the protocol level,
    where products have to agree on when bits
    are sent, how many will be sent at a time, and
    how the parties in a conversation can be sure
    that the message received is the same as the
    message sent.
    Applications of bluetooth!

    • Bluetooth speakers
    • Bluetooth headphones
    • Cable less connections to the printers
    • Bluetooth keyboard
    • Etc
    (NEAR FIELD COMMUNICATION)
    What is NFC?
    • NFC is a short-range high frequency wireless
    communication technology that enables the
    exchange of data between devices over about
    a 10 cm distance.
    • It allows devices to establish peer-to-peer
    radio communications, passing data from one
    device to another by touching them or putting
    them very close together.
    How NFC works?
    • NFC came out of RFID. RFID, or radio-frequency
    identification, is the technology used by superstores to
    keep track of goods, it uses electromagnetic induction in
    order to transmit information. NFC is similar technology,
    but standardized for consumer smartphones.
    • NFC is a means of sending data over radio waves. In that
    sense it is similar to Wi-Fi or Bluetooth, but unlike those
    protocols (and like RFID) NFC can be used to induce
    electric currents within passive components as well as
    just send data. And it is faster than Bluetooth.
    Benefits over Bluetooth..
    • The significant advantage of NFC over
    Bluetooth is the shorter set-up time.
    • Due to its shorter range, NFC provides a higher
    degree of security than Bluetooth and makes
    NFC suitable for crowded areas.
    • NFC can also work when one of the devices is
    not powered by a battery.
    • Unlike Bluetooth, no pairing code is needed.
    Applications…

    • NFC chips or tags are very small in size, it can


    be embedded in the movie posters, real estate
    agent posters etc.
    • Health care department.
    • NFC will replace car keys, ID badges and
    credit/debit cards.
    • Implementation in food packaging, flyers and
    merchandisers as well.
    What is wifi?
     Wifi 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.

     Wifi 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.

     Wifi is a generic term that refers to the IEEE 80211


    communications standard for wireless local area networks(WLANs)
    Lifi? (light fidelity)
    lifi is transmission of data through
    illumination by taking the fiber out of fiber
    optics by sending data through LED light bulb.
    This varies in intensity faster than human eye
    can follow.
    It is the fast and cheap wireless
    communication system which is optical
    version of wifi.
    Applications

    • In vehicles and traffic lights.


    • In aircrafts and underwater.
    • Hospitals
    • Street lamps
    • Petroleum and Chemical industries
