RFN_3.1 Beta

7  For Enhanced Security, RFN recommends that you select “On” to prevent 

RAPs from broadcasting their SSIDs. Then select Save Changes. 

For more information, refer to section 6.2.3 Enhanced Security for more 
information on using this setting. 

8  For User Access Control, RFN recommends that you select “On” to control 

which devices will have access to the customer LAN via the RFS. Then select 
Save Changes. 

For more information, refer to section 6.2.4 User Access Control for more 
information on using this setting. 

9  For Add MAC Address, enter the MAC address of each device that will be 

authorized to the use the customer LAN. You can enter MAC addresses one 
at a time, or copy them from a database or other file (Add MAC Addresses 
from file). You can also remove the entire list of MAC addresses (Remove 
All MAC Addresses), or save the list of MAC addresses to a file (Save MAC 
Addresses to File). 

For more information, refer to section 6.2.5 Add/Remove MAC Addresses for 
more information on using these options. 

The only mandatory RFS 802.11b configuration setting is the Service Set Identity 
(SSID). The SSID must be configured in all installations where 802.11b 
RadioFrame Access Points are installed. If the SSID is not configured, the 
802.11b capability will not be available. 

The SSID is necessary because, unlike wired LANs, a device which is part of an 
802.11 LAN may be within radio range of multiple “groups” of 802.11 stations. In 
order to isolate stations in one group from stations in another group, the SSID 
was created. It is an 802.11-only construct, which does not exist for any other 
type of LAN. The SSID identifies a collection of 802.11 stations for the purpose of 
communication as a group. 

The SSID is 1 to 32 characters in length. Typically, the SSID reflects the owner of 
the RFS. By default, the SSID is ‘RFN Customer’. This way, users can 
distinguish their LAN from any other 802.11 LAN which might physically overlap 
their area. 

For example, the SSID “RFN_Customer_Marketing” could provide the Marketing 
department at the RFN customer with its own distinct wireless LAN. Other 
departments within the RFN customer, such as “RFN_Customer_Operations”, 
might be in close proximity to the Marketing department. The staff in the two 
departments would both have 802.11 access to the company LAN, but their 
access would be provided via different RAPs, based on which SSID they use.
