Wireless Networks and Topologies;

 

 

 

 

 

    What do you mean by Wireless Network ?

     In wireless network computer, laptops, tablets and other devices are connected

     through network router than any usages of cables or wires  .

    In wi-fi based wireless network the access point or router act as an Ethernet switch

    All devices are directly connect to the router.

    The use of wireless networks to avoid costs of installing cables across the whole

    building. Generally wireless networks works with radio wave signals.

 

    Types of  Wireless  Networks :

     1.WPAN(Wireless Personal Area Network)

          Have a short range of 20-30 feet.Bluetooth is the best example which

          follows WPAN .

 2.   WLAN(Wireless Local Area Network)    :

        It extends  the communication to about 300ft and  consume  more  power.

 3: WMAN(Wireless Metropolitan Area Network):

       It ranges to a larger geographic area probably  city or suburb

4   WWAN(Wireless Wide Area Network):

     Provides connectivity over a large geographical area. These are networks used for 

     mobile phones and data service.

 

     Wireless Topologies:

     Basically  there   are  two  types  of wireless  topologies

        1. Infrastructure mode

        2. Independent  Basic Service Set(IBSS) 

     Let  us  understand  them  in detail:

      1. Infrastructure mode: It is also known as one to many topology. It has

          single  central  wireless  access points through  which  the  wireless

          client  connects  with  each  other .    

       2. Independent  Basic Service  Set(IBSS):In this topology  two  devices

           are connected  to  each  other wirelessly in a peer to peer  manner 

           without  the  use  of  an AP. It allows to  device  to  communicate

           with each other without  the  use of  any wireless device.
