Wireless networks communicate much different than wired networks. For a wireless device to communicate in a wireless network it would need to connect to a mobile network. For example you have a device and you pay a mobile company to providing service for you to use it. To provide service, the mobile company installs tall radio towers with antennas extending off the top. This would support phone calls and text between phones within that mobile network. You speak into your phone and your voice is transferred into bits which are sent out as radio waves to the antenna which is sent to the Telco network as bits and then transferred to its correct destination. This is only the beginning; to allow devices to communicate with more phones than the just the ones within the same network or to connect to data services (google.com, facebook.com) you would need to connect to networks around the world. The process is similar to connecting mobile phones in the same network except instead of the radio towers antenna sending the bits to the Telco network it sends the bits to the internet. This is all capable because the mobile phones do not use copper or fiber cables to transmit bits they use wireless radio technology.
Wireless LAN requires that every device connected to the network to have wireless NIC (network interface card). Wireless NIC’s do not need a socket to allow connection with a cable. Rather it has a radio antenna inside for the NIC to send and receive data. WLAN (Wirless Local Area Network) use small devices that perform like radio towers. Usually the wirless node they use is a WLAN access point. The devices nearby communicate through it because access point is connected to a switch which is then connected to a router and sent to
