Wireless Topologies / Internet and Networking

Wireless Topologies :- 
A wireless topology is one in which few cables are used to connect systems. The network is made up of transmitters that broadcast the packets using frequencies
A star - bus hybrid topology 

       The network contains special transmitters called calls,  or wireless access points,  which extend a radio sphere in the shape of a bubble around the transmitter.  This bubble can extend to multiple rooms and possibly floors in a building.  The PCs and network device have a special transmitter-receiver, which allows them to receive broadcasts and transmit requested data back to the access point.  The access point is connected to the physical network by a cable,  which allows it,  and any wireless clients,  to communicate with systems on the wired network.  A wireless network topology 

Wireless topologies that the wireless cells,  or access points,  are connected to the network by connecting into the hub or switch that has a connection to the rest of the wired network.  Also notice that the clients,  and they will get access to the network through the wireless cells (or access point). 

Another option for wireless networks is the use of a radio antenna on or near the building,  which allows one cell to cover the building and the surrounding area.  This approach is best in a campus-type arrangement, where many building that need to be included in the cell are in a clos3 geographical area.  This setup does not easily
