Introduction to Wireless Networks

External Resources

A wireless network requires less cabling than the normal wired network. The wireless network is made up of transmitters that broadcast the packets using radio frequencies (microwave). The wireless network contains special transmitters called wireless Access Points. The workstations and network devices have a special transmitter-receiver, which allows them to receive broadcasts and transmit requested data back to the cell access point. The cell access point is connected to the physical network by a cable, which allows it, and other wireless clients, to communicate with systems on the wired network. The network devices and the Access Point communicate using one of several communications protocols, including IEEE 802.11. Wireless network technology can connect a campus, a building, or even a whole city.

The advantages are wireless networks over wired networks are easy to troubleshoot and need less cabling. Main disadvantage of wireless networks is that they can be extremely unsecure if not configured properly. Other disadvantages are greater chance of signal interference, blockage, and interception.
