¾ 108M Super G
™
WLAN Transmission Technology
- 108M Super G ™ WLAN Transmission
Technology employs multiple performance-enhancing techniques including packet bursting,
fast frames, data compression, and dynamic turbo mode that combine to improve the
throughput and range of wireless networking products. Users can experience link rates of up
to 108Mbps, twice the industry-standard maximum data link rate of 54Mbps, while preserving
full compatibility with traditional 802.11g or 802.11b networks. 108M Super G ™ products offer
the highest throughput performance available on the market today. In dynamic 108M mode,
the device can attach 802.11b, 802.11g and 108Mbps Super G ™ devices at the same time in
an integrated environment.
¾ 2x to 3x eXtended Range
™
WLAN Transmission Technology - The WLAN device with 2x
to 3x eXtended Range ™ WLAN transmission technology make its sensitivity up to 105 dB,
which gives users the ability to have robust, longer-range wireless connections. With this
range-enhancing technology, a 2x to 3x eXtended Range ™ based client and access point can
maintain a connection at as much as three times the transmission distance of traditional
802.11b and 802.11g products, for a coverage area that is up to nine times greater. A
traditional 802.11b and 802.11g product transmission distance is about 300m, A 2x to 3x
eXtended Range ™ based client and access point can maintain a connection transmission
distance may be up to 830m.
¾ 802.11b - The 802.11b standard specifies a wireless networking at 11 Mbps using
direct-sequence spread-spectrum (DSSS) technology and operating in the unlicensed radio
spectrum at 2.4GHz, and WEP encryption for security. 802.11b networks are also referred to
as Wi-Fi networks.
¾ 802.11g - specification for wireless networking at 54 Mbps using direct-sequence
spread-spectrum (DSSS) technology, using OFDM modulation and operating in the
unlicensed radio spectrum at 2.4GHz, and backward compatibility with IEEE 802.11b devices,
and WEP encryption for security.
¾ DDNS (Dynamic Domain Name System) - The capability of assigning a fixed host and
domain name to a dynamic Internet IP Address.
¾ DHCP
(Dynamic Host Configuration Protocol) - A protocol that automatically configure the
TCP/IP parameters for the all the PC(s) that are connected to a DHCP server.
¾ DMZ (Demilitarized Zone) - A Demilitarized Zone allows one local host to be exposed to the
Internet for a special-purpose service such as Internet gaming or videoconferencing.
¾ DNS
(Domain Name System) – An Internet Service that translates the names of websites into
