 WLAN Transmission Technology  - 108M Super G

TM

 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

TM

 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

TM

  devices at the same time in an 

integrated environment. 

 

 WLAN Transmission Technology - The WLAN device 

with 2x to 3x eXtended Range

TM

 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

TM

 

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

TM

 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. 

 

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.   

 

DHCP  (Dynamic  Host  Configuration  Protocol)  - A protocol that automatically 
configure the TCP/IP parameters for the all the PCs that are connected to a DHCP 
server. 

 

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. 

 

DNS  (Domain  Name  System)  – An Internet Service that translates the names of 
websites into IP addresses.
