NETCOMM LIBERTY SERIES - HSPA WiFi Router with Voice
DESCRIPTION
Select On or Off. By enabling this feature, wireless clients associated with the Access Point can be linked.
The new amendment allows IEEE 802.11g units to fall back to speeds of 11 Mbps, so IEEE 802.11b and IEEE
802.11g devices can coexist in the same network. The two standards apply to the 2.4 GHz frequency band. IEEE
802.11g creates data-rate parity at 2.4 GHz with the IEEE 802.11a standard, which has a 54 Mbps rate at 5 GHz.
(IEEE 802.11a has other differences compared to IEEE 802.11b or g, such as offering more channels.)
Allows selection of a specific channel (1-14) or Auto mode.
The Auto Channel times the length it takes to scan in minutes.
In Auto (default) mode, your Router uses the maximum data rate and lowers the data rate dependent on the signal
strength. The appropriate setting is dependent on signal strength. Other rates are discrete values between 1 to 54
Mbps.
Setting for multicast packet transmission rate. (1-54 Mbps)
Sets basic transmission rate.
A threshold (in bytes) determines whether packets will be fragmented and at what size. Packets that exceed the
fragmentation threshold of an 802.11 WLAN will be split into smaller units suitable for the circuit size. Packets
smaller than the specified fragmentation threshold value however are not fragmented. Values between 256 and 2346
can be entered but should remain at a default setting of 2346. Setting the Fragmentation Threshold too low may
result in poor performance.
Request To Send (R TS) specifies the packet size that exceeds the specified R TS threshold, which then triggers the
R TS/CTS mechanism. Smaller packets are sent without using R TS/CTS. The default setting of 2347 (max length) will
disables the R TS Threshold.
Delivery Traffic Indication Message (DTIM) is also known as Beacon Rate. The entry range is a value between 1
and 65535. A DTIM is a countdown variable that informs clients of the next window for listening to broadcast and
multicast messages. When the AP has buffered broadcast or multicast messages for associated clients, it sends
the next DTIM with a DTIM Interval value. AP Clients hear the beacons and awaken to receive the broadcast and
multicast messages. The default is 1.
The amount of time between beacon transmissions in is milliseconds. The default is 100 ms and the acceptable
range is 1 – 65535. The beacon transmissions identify the presence of an access point. By default, network devices
passively scan all RF channels listening for beacons coming from access points. Before a station enters power save
mode, the station needs the beacon interval to know when to wake up to receive the beacon.
