Infrastructure Network - An infrastructure network is a group of computers or
other devices, each with a wireless adapter, connected as an 802.11 wireless LAN. In
infrastructure mode, the wireless devices communicate with each other and to a
wired network by first going through an access point. An infrastructure wireless
network connected to a wired network is referred to as a Basic Service Set (BSS). A
set of two or more BSS in a single network is referred to as an Extended Service Set
(ESS). Infrastructure mode is useful at a corporation scale, or when it is necessary to
connect the wired and wireless networks.Spread Spectrum
- Spread Spectrum
technology is a wideband radio frequency technique developed by the military for use
in reliable, secure, mission-critical communications systems. It is designed to trade
off bandwidth efficiency for reliability, integrity, and security. In other words, more
bandwidth is consumed than in the case of narrowband transmission, but the trade
off produces a signal that is, in effect, louder and thus easier to detect, provided that
the receiver knows the parameters of the spread-spectrum signal being broadcast. If
a receiver is not tuned to the right frequency, a spread-spectrum signal looks like
background noise. There are two main alternatives, Direct Sequence Spread
Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS).
SSID - A
Service Set Identification is a thirty-two character (maximum)
alphanumeric key identifying a wireless local area network. For the wireless devices
in a network to communicate with each other, all devices must be configured with the
same SSID. This is typically the configuration parameter for a wireless PC card. It
corresponds to the ESSID in the wireless Access Point and to the wireless network
name. See also Wireless Network Name and ESSID.
WEP
(Wired Equivalent Privacy) - A data privacy mechanism based on a 64-bit or
128-bit or 152-bit shared key algorithm, as described in the IEEE 802.11 standard.
Wi-Fi
- A trade name for the 802.11b wireless networking standard, given by the
Wireless Ethernet Compatibility Alliance (WECA, see http://www.wi-fi.net), an
industry standards group promoting interoperability among 802.11b devices.
WLAN
(Wireless Local Area Network) - A group of computers and associated devices
communicate with each other wirelessly, which network serving users are limited in a
local area.
WPA
(Wi-Fi Protected Access) - A wireless security protocol use TKIP (Temporal Key
Integrity Protocol) encryption, which can be used in conjunction with a RADIUS
server.

2x to 3x eXtended RangeWLAN Transmission Technology
- The WLAN device
with 2x to 3x eXtended RangeTM 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 RangeTM 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 LANPRO 2x to 3x eXtended RangeTM 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 product 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.
Ad-hoc Network
- An ad-hoc network is a group of computers, each with a wireless
adapter, connected as an independent 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.
(Direct-Sequence Spread Spectrum) - DSSS generates a redundant bit pattern for
DSSS
all data transmitted. This bit pattern is called a chip (or chipping code). Even if one or
more bits in the chip are damaged during transmission, statistical techniques embedded
in the receiver can recover the original data without the need for retransmission. To an
unintended receiver, DSSS appears as low power wideband noise and is rejected
(ignored) by most narrowband receivers. However, to an intended receiver (i.e. another
wireless LAN endpoint), the DSSS signal is recognized as the only valid signal, and
interference is inherently rejected (ignored).
(Frequency Hopping Spread Spectrum) - FHSS continuously changes (hops) the
FHSS
carrier frequency of a conventional carrier several times per second according to a
pseudo-random set of channels. Because a fixed frequency is not used, and only the
transmitter and receiver know the hop patterns, interception of FHSS is extremely
difficult.
Note:
If any of the listed contents are damaged or missing, please contact the
retailer from whom you purchased the LP-510G/LP-550G Wireless Adapter for

802.11b Preamble: Specifies the preamble setting in 802.11b. The default setting is
Short & Long (access point mode), which allows both short and long headers in the
802.11b frames. The adapter can only use short radio headers if the access point
supports and uses them. Set to Long Only to override allowing short frames.
If the icon is green, there is good signal strength and the RSSI is between 10dB
and
20dB.
If the icon is green, there is excellent signal strength and the RSSI is more
than 20dB.
Double-click the icon and the LWCU will run. You can also run the utility by clicking the

The section below introduces these above capabilities.
Wireless Mode:
Specifies 2.4 GHz 54 Mbps or 2.4 GHz 11 Mbps operation in an access
point network. The wireless adapter must match the wireless mode of the access point
with which it associates.
Wireless Mode
when Starting an Ad Hoc Network: Specifies 2.4 GHz 54/11 Mbps to
start an Ad Hoc network if no matching network name is found after scanning all
available modes. This mode also allows the selection of the channel the wireless adapter
uses. The channels available depend on the regulatory domain. If the adapter finds no
other ad hoc adapters, the channel that the adapter starts the ad hoc network with will
be selected automatically. The wireless adapter must match the wireless mode and
channel of the clients it associates.
802.11 Authentication Mode: Select
which mode the wireless adapter uses
to authenticate to an access point:
• Automatic
causes the adapter to
attempt authentication using shared,
but switches it to open authentication
if shared fails.
• Open System
enables an adapter to
attempt authentication regardless of
its WEP settings. It will only associate
with the access point if the WEP keys
on both the adapter and the access

point match.
• Shared-key
only allows the adapter
to associate with access points that
have the same WEP key.
For infrastructure (access point) networks, click Preferred APs… to specify up to four
access points to the client adapter that attempt to be associated to the access
points.
