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.
Access Point -
A device that allows wireless-equipped computers and other devices to
communicate with a wired network. Also used to expand the range of a wireless network.
Ad-hoc Network -
An ad-hoc network is a group of computers, each with a wireless adapter,
connected as an independent IEEE 802.11 wireless LAN. Ad-hoc wireless computers operate on
a peer-to-peer basis, communicating directly with each other without the use of an access point.
Ad-hoc mode is also referred to as an Independent Basic Service Set (IBSS) or as peer-to-peer
mode, and is useful at a departmental scale or SOHO operation.

encryption.
ATM (A

) -
ATM is a cell based transfer mode that requires variable
length user information to be segmented and reassembled to/from short, fixed length cells. It uses
two different methods for carrying connectionless network interconnect traffic, routed and bridged
Protocol Data Units (PDUs), over an ATM network.
Bridging -
A device that connects different networks.
Browser -
An application program that provides a way to look at and interact with all the
information on the World Wide Web.

-
Allows the hosting of a website, FTP server, or e-mail
server with a fixed domain name (e.g., www.xyz.com) and a dynamic IP address.
Default Gateway -
A device that forwards Internet traffic from your local area network.
DHCP -
A networking protocol that allows administrators to assign temporary IP addresses to
network computers by “leasing” an IP address to a user for a limited amount of time, instead of
assigning permanent IP addresses.
