network topology
A wireless Local Area Network (LAN) uses a wireless adapter to connect each
computer to the network. Computers in a wireless network must be configured to
share the same radio channel.
The Wireless USB Network Adapter provides wireless computers access to a wired
network. This integrated wireless and wired network is called an “infrastructure”
configuration. A group of wireless-network-adapter-equipped computers plus a
wireless access point, such as the HP Wireless Network Access Point, is called a
Basic Service Set (BSS). The wireless access point connects the wireless network to
the conventional wired network. Each wireless-network-adapter-equipped computer
can communicate with any computer in a wired network infrastructure via the
wireless access point.
An infrastructure configuration doubles the effective wireless transmission range of
two wireless-network-adapter-equipped PCs since the wireless access point
forwards data within the network. It is essential to use a unique ID, a BSSID or,
more generically, an SSID within a wireless network. All PCs within an independent
wireless network that are configured without roaming options (see Roaming below)
must be configured with the same wireless network ID.
The wireless network infrastructure configuration is appropriate for enterprise-scale
wireless access to a central database and for mobile users.
Infrastructure mode also supports roaming capabilities for mobile users. A multiple
wireless network can be configured as an “extended” wireless network, known as
an Extended Service Set (ESS), allowing users to roam freely within it. All wirelessnetwork-adapter-equipped PCs within one extended network must be configured
with the same extended network ID an ESSID or taken generically with a BSSID as
discussed above, called an SSID, and must use the same radio channel.
Before enabling an extended wireless network with roaming capability, select a
feasible radio channel and an optimal location for the wireless access point. Proper
wireless access point positioning and a clear radio signal will enhance

wireless FAQs
Can I run an application from a remote computer over the wireless network?
This depends on whether the application is designed to be used over a network.
Consult the application’s documentation to determine if it supports operation
over a network
Can I play computer games with other members of the wireless network?
Yes, as long as the game supports multiple players over a local area network
(LAN). Refer to the game’s documentation for more information.
What is the IEEE 802.11 standard?
The IEEE 802.11 Wireless LAN Standards Subcommittee of the Institute of
Electrical and Electronics Engineers (IEEE) is formulating a standard for the
industry to enable wireless LAN hardware from different manufacturers to
communicate with one another.
What IEEE 802.11 features are supported?
HP wireless products support the following IEEE 802.11 functions:

communications session. An ad-hoc wireless LAN is applicable at a
departmental scale for a branch or SOHO (small office/home office) operation.
ADSL (Asymmetric Digital Subscriber Line)
A DSL modem technology geared to acceptable Internet performance in which
downstream data transfer (downloading data from the Internet to the subscriber)
is faster than upstream data transfer (uploading data from the subscriber).
ATM (Asynchronous Transfer Mode)
Asynchronous transfer mode (broadband switching). ATM (asynchronous
transfer mode) — a dedicated-connection switching technology that transmits
digital data over a physical medium using digital signal technology. An
individual cell is processed asynchronously relative to other related cells and is
queued before being multiplexed over the transmission path.
Fast Internet access through DSL, cable modem, or other means.
BSS (Basic Service Set)
One wireless network.
BSSID (Basic Service Set Identification)
A unique name (or ID) used by all computers on the network. A specific ad-hoc
LAN. Computers in a BSS must be configured with the same BSSID.
bus topology
Simple way of connecting computers in a network linearly along a single cable
(each connected to the cable, not one to another).
wireless USB network adapter
client/server network
Network in which one computer (the “server”) shares resources with other
computers, called “clients” (as opposed to a peer-to-peer network).
CSMA/CD (Carrier Sense Multiple Access/Collision Detect)
The protocol for carrier transmission access in an Ethernet network in which
each device senses whether the line is idle and then sends data. If another
device sends data at the same time, a collision occurs, the data is discarded,
and the devices try again.
default gateway
The router used to forward all traffic not addressed to a station within the local
DHCP (Dynamic Host Configuration Protocol)
A utility for assigning TCP/IP addresses to workstations automatically (a unique
IP address must be assigned to each computer in the network). When computers
are moved within the network, DHCP allows automated IP addresses to be
assigned automatically. DHCP “leases” an IP address to a device for a specific
amount of time, which is useful in education and other environments where
users change frequently. DHCP also supports static IP addresses for computers
needing a permanent IP address, such as those containing Web servers. See
static IP address.
DCHP Client
A device configured to receive a DHCP address.
DHCP Server
A device configured to assign IP addresses to DHCP clients.
DMZ (Demilitarized Zone)

company’s private network and the external public network. It prevents outside
users from having access to an internal server containing confidential data.
DMZ Hosting
Allows one IP address (or computer) to be exposed to the Internet. Some
applications require multiple TCP/IP ports to be open. It is recommended that
you set your computer with a static IP address if you want to use DMZ Hosting.
DNS (Domain Name System)
Method for matching Internet domain names with IP addresses. When a
Uniform Resource Locator (URL) is entered into a Web browser, a domain name
server retrieves the corresponding IP address for the domain name specified
(“name resolution”) and sends the request to the appropriate server. Domain
names are convenient “handles” for IP addresses.
DSL (Digital Subscriber Line)
Transmits data bi-directionally at high speeds.
DSSS (Direct Sequence Spread Spectrum )
Generates a redundant bit pattern for each bit to be transmitted. This bit pattern
is called a chip (or chipping code). The longer the chip, the greater the
probability that the original data can be recovered. Even if one or more bits in
the chip are damaged during transmission, statistical techniques embedded in
the radio 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.
dynamic IP address
An IP address that is automatically assigned (typically by a DHCP server) in a
TCP/IP network, as opposed to a static IP address.
ESS (Extended Service Set)
More than one wireless network.
ESSID (Extended Service Set Identification)
A unique name (or ID) used by users roaming among the multiple wireless
networks. An infrastructure configuration can support roaming capability for
mobile workers. More than one BSS can be configured as an ESS. Users within
an ESS can roam freely between BSSs while served as a continuous connection
to the network. Wireless stations and wireless access points within an ESS must
be configured with the same ESSID and radio channel.
Protocol and cabling scheme allowing transfer of data at 10 Mbps.
Ethernet card
See NIC (Network Interface Card).
wireless USB network adapter
FHSS (Frequency Hopping Spread Spectrum)
Uses a narrowband carrier that changes frequency in a pattern known to both
transmitter and receiver. Properly synchronized, the net effect is to maintain a
single logical channel. To an unintended receiver, FHSS appears to be shortduration impulse noise.
A set of related programs, located at a network gateway server, that protects
the resources of a network from users in other networks. It also controls access
of internal users to outside resources. A firewall, working closely with the
Gateway, examines each network packet to determine whether or not to
forward it to its destination.
