| channel uses two standard channels and offers speeds of up to 300 Mbps. |
| 40MHz (channel bonding or dual channel) bonds two adjacent radio channels to increase |
| throughput. The wireless clients must also support 40 MHz. It is often better to use the 20 |
| MHz setting in a location where the environment hinders the wireless signal. |
| Select 20MHz if you want to lessen radio interference with other wireless devices in your |

7.10.1 Wireless Network Overview
Wireless networks consist of wireless clients, access points and bridges.
•A wireless client is a radio connected to a user’s computer.
•An access point is a radio with a wired connection to a network, which can connect with numerous wireless clients and let them access the network.
•A bridge is a radio that relays communications between access points and wireless clients, extending a network’s range.
Traditionally, a wireless network operates in one of two ways.
