Wireless networks allow computers to communicate without the use of cables. This is also commonly known as Wi-Fi. A connection is made from a device, which is usually a PC or a Laptop with a wireless card, to a Wireless Access Point (WAP), which acts as a bridge between the wireless network and the wired networks. Wireless network standards are specified by IEEE 802.11.
There are many flavors of 802.11, but we will only be concerned with four. Each increases the distance and speed of your wireless network.
| Name | Speed | Distance | Frequency |
| 802.11a | 54 Mbps | 30m | 5 GHz |
| 802.11b | 11 Mbps | 91m | 2.4 GHz |
| 802.11g | 54 Mbps | 91m | 2.4 GHz |
| 802.11n | 540 Mbps | 182m | 5 and 2.4 GHz |
