HSG Wireless Hotspot Gateway ENGLISH
unauthorized wireless association if necessary. The encryption standards supported are WEP and
WPA-PSK.
Advanced: The parameters in Advanced are wireless settings that allow customization of data

transmission, enhanced security and wireless roaming.
Beacon Interval: The entered amount of time indicates how often the beacon signal will be sent
from the VAP. The default value is set at 100ms.
RTS Threshold: Enter a value between 1 and 2346. RTS (Request to Send) Threshold
determines the packet size at which the system issues a request to send (RTS) before sending the
frame to prevent the hidden node problem. The RTS mechanism will be activated if the data size
exceeds the value provided. A lower RTS Threshold setting can be useful in areas where many
client devices are associating with the HSG or in areas where the clients are far apart and can
detect only the HSG but not each other. The default value is set at 2346.
Fragment Threshold: Enter a value between 256 and 2346. The default value is 2346. A packet
size larger than this threshold will be fragmented (sent with several pieces instead of one chunk)
before transmission. A smaller value results in smaller frames but allows a larger number of
frames in transmission. A lower Fragment Threshold setting can be useful in areas where
communication is poor or disturbed by a serious amount of radio interference.
Broadcast SSID: Enable to broadcast VAP2's SSID in the air, Disable to hide VAP's SSID so that
it cannot be scanned.
Station Isolation: By enabling this function, all stations wirelessly associated to this zone are
isolated from one another and can only communicate with the system.
WMM: The default is Enable. Wi-Fi Multimedia (WMM) is a Quality of Service (QoS) feature that
prioritizes wireless data packets based on four access categories: voice, video, best effort, and
background. Applications without WMM and applications that do not require QoS are assigned to
the best-effort category, which receives a lower priority than that of voice and video. Therefore,
WMM decides which data streams are more important and assigns them a higher traffic priority.
This option works with WMM-capable clients only.
IGMP Snooping: IGMP is a multicast constraining mechanism which may flood the broadcast
domain. This is effective for dense internet usage such as conventions or campuses.
