30 – 3G10WV HSPA Wi-Fi Router with Voice
Option Description
AP Isolation
Select On or Off. By enabling this feature, wireless clients associated with the Access
Point can be linked.
Band
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.)
Channel
Allows selection of a specific channel (1-14) or Auto mode.
Auto Channel Timer
(min)
The Auto Channel times the length it takes to scan in minutes.
54g Rate
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.
Multicast Rate
Setting for multicast packet transmission rate. (1-54 Mbps)
Basic Rate
Sets basic transmission rate.
Fragmentation
Threshold
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.
RTS Threshold
Request To Send (RTS) specifies the packet size that exceeds the specified RTS threshold,
which then triggers the RTS/CTS mechanism. Smaller packets are sent without using
RTS/CTS. The default setting of 2347 (max length) will disables the RTS Threshold.
DTIM Interval
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.
Beacon Interval
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.
Xpress™
Technology
Broadcom’s Xpress™ Technology is compliant with draft specifications of two planned
wireless industry standards. It has been designed to improve wireless network efficiency.
