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.

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.

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.

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.
