Wireless > Wlan Setup - Advantech EKI-6340 Series User Manual

Antenna Number: EKI-6340 series completes 802.11n 1x1 1-steram and 2x2 2-
stream for antenna attached. The maximum data link rate at 1-steram and 2-stream
will be 150Mbps and 300Mbps.
Short Guard Interval: The guard interval is the space between symbols (characters)
being transmitted. Adding time between symbol transmissions allows these echoes
and reflections to settle in before the next symbol is transmitted. In normal 802.11
operations, the guard interval is 800 ns. A short guard interval will shorten the time
between symbol transmissions into 400 ns to enhance the efficiency of data trans-
mission.
Aggregation: Frame aggregation is a feature of the 802.11n wireless LAN standards
that increases throughput by sending two or more data frames in a single transmis-
sion.
Distance: To assign a distance between nodes in a point to point transmission will
improve the throughput rate.

SSID: A service set identifier (SSID) is a name that identifies a particular 802.11 wire-
less LAN. A client device receives beacon messages from all access points within
range advertising their SSIDs. The client device can then either manually or automat-
ically select the network with which to associate.
Broadcast: Network administrator can choose broadcast beacon messages of a vir-
tual AP by checking the broadcast block.
Enable: Network administrator can also decide if function virtual AP or let it idle.
WLAN Mode Radios support "Access Point", "Wireless Station", "Access Point (WDS
Support)", "Wireless Station (WDS Support)", "MESH Mode" and "Mobility Mode"
mode to meet various network scenarios.
"Access Point" and "Wireless Station" are the AP/Client infrastructure running
between EKI-6340 series.
