Network Setup
8.Select a channel for communications between the access port and MUs in the Desired Channel field.
The selection of a channel determines the available power levels. The range of legally approved communication channels varies depending on the installation location and country. The selected channel can be a specific channel, “Random,” or “ACS.” Random assigns each radio a random channel. ACS (Automatic Channel Selection) allows the switch to systematically assign channels. Default is Random.
9.After first selecting a channel, select a power level in dBm for RF signal strength in the Desired Power (dBm) field.
The optimal power level for the specified channel is best determined by a site survey prior to installation. Available settings are determined according to the selected channel. Set a higher power level to ensure RF coverage in WLAN environments that have more electromagnetic interference or greater distances between the access port and MUs. Decrease the power level according to the proximity of other access ports. Overlapping RF coverage may cause lost packets and difficulty for roaming devices trying to
engage a access port. After setting a power level, channel and placement the RF output power for the access port is displayed in mW. Default is 20 dBm (802.11bg), 17 dBm (802.11a))
NOTE: After setting a power level, channel and placement the RF output power for the access port is displayed below in mW.
10.To configure optional rate settings, click the Rate Settings button to display a new dialogue containing rate setting information. Instructions on configuring rate settings are described in Configuring Rate Settings on page
11.In most cases, the default settings for the Advanced Properties section are sufficient for most users. If needed, additional radio settings can be modified for the following properties:
Antenna Diversity Use the
•Full Diversity: Utilizes both antennas to provide antenna diversity.
•Primary Only: Enables only the primary antenna.
•Secondary Only: Enables only the secondary antenna.
Antenna Diversity should only be enabled if the access port has two matching external antennas. Default value is Full Diversity.
Maximum MUs | Sets the maximum number of MUs that can associate to a radio. The maximum number of |
| stations that can associate to a radio are 64. |
Adoption Preference | The Adoption Preference ID defines the preference ID of the switch.The value can be set |
ID | between 1 and 65535. To make the radios preferred, the access port preference ID should be |
| same as adoption preference ID. |
| The adoption preference id is used for RP |
| access ports which have the same |
Short Preambles only | If using an 802.11 bg radio, select this checkbox for the radio to transmit using a short |
| preamble. Short preambles improve throughput. However, some devices (SpectraLink |
| phones) require long preambles. This checkbox does not display if using an 802.11a radio. |
