iPECS SBG-1000 User Manual (DATA Features)
DTIM Interval The Delivery Traffic Indication Message (DTIM) is a countdown value that informs
wireless clients of the next opportunity to receive multicast and broadcast messages. This value
ranges between 1 and 16384.
Fragmentation Threshold Packets that are larger than this threshold are fragmented into
multiple packets. Try to increase the fragmentation threshold if you encounter high packet error
rates. Do not set the threshold too low, since this can result in reduced networking performance.
RTS Threshold iPECS SBG-1000 sends Request to Send (RTS) packets to the wireless client in
order to negotiate the dispatching of data. The wireless client responds with a Clear to Send (CTS)
packet, signaling that transmission can commence. In case packets are smaller than the preset
threshold, the RTC/CTS mechanism is not active. If you encounter inconsistent data flow, try a
minor reduction of the RTS threshold size.
6.4.5.5.7 Virtual Access Points
You can set up multiple virtual wireless LANs on iPECS SBG-1000 up to four connections. Such
virtual wireless LANs are referred to as “Virtual APs” (virtual access points).
The ‘Virtual APs’ section appears under the ‘Wireless’ sub-tab of the ‘LAN Wireless 802.11n
Access Point Properties’ screen, and displays iPECS SBG-1000’s physical wireless access point,
on top of which virtual connections may be created.
Figure 6.81 Virtual APs
To create a virtual connection, click the ‘New Virtual AP’ link. The screen refreshes, displaying the
new virtual connection.
Figure 6.82 New Virtual Access Point
The new connection will also be added to the network connections list, and will be configurable like
any other connection.
