opportunity, it can transmit data for a time up to the TxOpLimit. This data bursting
greatly improves the efficiency for high data-rate traffic. Specify a value in the
range 0-65535 microseconds.
◆ ACM — The admission control mode for the access category. When enabled,
clients are blocked from using the access category. (Default: Disabled)
◆ AckPolicy — By default, all wireless data transmissions require the sender to wait
for an acknowledgement from the receiver. WMM allows the acknowledgement wait
time to be turned off for each Access Category (AC) 0-3. Although this increases
data throughput, it can also result in a high number of errors when traffic levels are
heavy. (Default: Acknowledge)
MULTICAST-TOUNICAST
CONVERTER
The Multicast-to-Unicast Converter section on the Wireless Settings
Advanced page allows you to enable multicast traffic conversion.
Converting multicast traffic to unicast before sending to wireless clients allows a
longer DTIM (Data Beacon Rate) interval to be set. A longer DTIM interval prevents
clients in power-save mode having to activate their radios to receive the multicast
data, which saves battery life.
◆ Multicast-to-Unicast — Enables multicast traffic streams to be converted to unicast
traffic before delivery to wireless clients. (Default: Disabled)
WLAN SECURITY
The 3G Mobile Wireless Router’s wireless interface is configured by default as an
―open system,‖ which broadcasts a beacon signal including the configured SSID.
Wireless clients with a configured SSID of ―ANY‖ can read the SSID from the beacon,
and automatically set their SSID to allow immediate connection to the wireless
network.
To implement wireless network security, you have to employ one or both of the
following functions:
◆ Authentication — It must be verified that clients attempting to connect to the
network are authorized users.
◆ Traffic Encryption — Data passing between the unit and clients must be protected
