2.3.1 Wireless Basics
802.11b/g |
|
| 802.11b is an IEEE standard, operating at 2,4 GHz at a speed of up to 11 Mb/s. | |
|
|
| 802.11g, a newer IEEE standard also operating at 2,4 GHz, gives you up to 54 | |
|
|
| Mb/s speed, more security and better performance. | |

Access Point |
|
|
|
|
The SpeedTouch™ Wireless LAN Access Point (AP) behaves as a networking hub | ||||
| allowing to wirelessly interconnect several devices to the local (W)LAN and to | |||
| provide access to the Internet. |
| ||
Network Name or SSID |
|
|
|
|
The WLAN's 'radio' link is a shared medium. As no physical connection exists | ||||
| between the SpeedTouch™ and wireless clients, a name must be given to allow | |||
| unique identification of your WLAN radio link. This is done by the Service Set ID | |||
| (SSID), also referred to as Network Name. Wireless clients must be part of this SSID | |||
| environment in order to be able to communicate with other clients on the (W)LAN - | |||
| including the SpeedTouch™. |
| ||
Radio channels |
|
|
|
|
The 802.11g standard allows several WLAN networks using different radio channels | ||||
| to be | |||
| select the best radio channel at each startup. | |||
| You can choose to set the channels automatically or manually. | |||
|
|
| The different channels overlap. To avoid interference with another access | |
|
|
| ||
|
|
| ||
|
|
| point, make sure that the separation (in terms of frequency) is as high as | |
|
|
| ||
|
|
| possible. It is recommended to keep at least 3 channels between 2 different | |
|
|
| access points. |
|
| The SpeedTouch™ supports all channels allowed for wireless networking. However, | |||
| depending on local regulations, the number of channels actually allowed to be used | |||
| may be additionally restricted, as shown in the table below. | |||
