1-3 Using a Wireless Local Area Network
A wireless LAN provides the same functionality of a wired network, but it eliminates the need to
install networking cables and other networking equipment. Not only is a wireless LAN easier to
deploy, but it also allows for mobility through “roaming.” For example, the ORiNOCO 11a/b/g
CamboCard can roam from a conference room to an office without being disconnected from the
network.

1-5 System Requirements and Specifications
To begin using an ORiNOCO Wireless Client, you must have the following minimum
requirements:
1. A computer that meets the following specifications:
l Windows XP, Windows 2000, Windows Millennium Edition (ME), or Windows 98 Second
Edition (SE) installed
l PC Card expansion slot (32-bit CardBus) for ORiNOCO a/b ComboCard, ORiNOCO
11a/b/g ComboCard, ORiNOCO 11b/g PC Card
l 32-bit PCI bus slot on your desktop for the ORiNOCO 11a/b/g PCI Card.
l At least 64 MB of memory
l A 300 MHz processor or higher
2. At least one other IEEE 802.11a-compliant, 802.11b-compliant or 802.11g-compliant device
l Customers in Europe who want to use the card in 802.11a mode need an
802.11a-compliant Access Point that supports Dynamic Frequency Selection (DFS);
802.11a Peer-to-Peer Groups are not available in Europe (see the user documentation
that came with your 802.11a Access Point for details).
1-5-1 The IEEE 802.11 Specifications
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard
for wireless devices operating in the 2.4 GHz frequency band. This standard includes provisions
for three radio technologies: direct sequence spread spectrum, frequency hopping spread
ORiNOCO Wireless Client User Guide
Chapter 2 Installation 8
spectrum, and infrared. Devices that comply with the 802.11 standard operate at a data rate of
either 1 or 2 Mbps.
In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can
operate at speeds of up to 11 Mbps. The IEEE ratified this standard as 802.11b. 802.11b devices
are backwards compatible with 2.4 GHz 802.11 direct sequence devices (that operate at 1 or
2 Mbps).
Also in 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz
frequency band. This standard is referred to as 802.11a. 802.11a devices are not backward
compatible with 2.4 GHz 802.11 or 802.11b devices. 802.11a radios use a radio technology
called Orthogonal Frequency Division Multiplexing (OFDM) to achieve data rates of up to 54
Mbps. In addition, ORiNOCO Wireless Clients that support the 802.11a standard also support
Proxim’s 2XTM Turbo mode. This mode is not part of the IEEE 802.11a standard but delivers data
rates of up to 108 Mbps. Note that 2X Turbo mode is only available in the FCC regulatory domain
(e.g., the United States)
In 2003, the IEEE ratified the 802.11g standard. This standard delivers the same 54Mbps
maximum data rate as 802.11a, yet it offers an additional and compelling advantage-backward
compatibility with 802.11b equipment. This means that 802.11b client cards will work with
802.11g access points, and 802.11g client cards will work with 802.11b access points. Note that
802.11b products cannot be upgraded to support 802.11g since the 802.11g radios use a
different chipset than 802.11b devices. However, 802.11g products and 802.11b products can
work in the same network. Because 802.11g and 802.11b operate in the same unlicensed band,
the two standards share the same three channels, which can limit wireless capacity and
scalability.
Since 802.11a, 802.11b, 802.11d and 802.11g are based on the same common standard (IEEE
802.11), 802.11a, 802.11b and 802.11g devices have many of the same parameters. This user
guide uses the generic term 802.11 to refer to parameters that apply to 802.11a, 802.11b and
802.11g devices.
An 802.11a device and an 11b/g device cannot communicate with
each other. Also, a device in 802.11a 2X mode and a device
operating in 802.11a mode (2X mode disabled) cannot
communicate.
In addition to the three standards above, the IEEE 802.11 committee has also ratified the
802.11d standard. When 802.11 first became available, only a handful of regulatory domains
(e.g., U.S., Europe, and Japan) had rules in place for the operation of 802.11 wireless LANs. In
order to support a widespread adoption of 802.11, the IEEE committee created the 802.11d task
group to define an operational procedure that satisfies the regulatory requirements within all
countries. This is especially important for operation in the 5GHz bands because the use of these
frequencies differ widely from one country to another.
802.11d is a “regulatory domain update.” The idea behind 802.11d is that the wireless Access
Point (AP) can tell a client in what country it is located and what operating channels and transmit
power levels are legal in that country. In some countries, wireless LANs in the 802.11-defined
bands are not legal. With 802.11d, in theory, an Access Point could describe the “legal”
configuration to wireless clients so that wireless LANs could be deployed in those countries.
The ORiNOCO Wireless Client supports the 802.11d standard. Note that this standard does not
have a direct visible impact on end user operation: it primarily applies to companies developing
802.11 products.

Chapter 3 Wireless Topologies
3-1 Introduction
ORiNOCO wireless products look and operate similar to Ethernet products. The only difference
is that a radio replaces the wire between communicating devices. This means that all of your
existing applications that operate over Ethernet will work with the ORiNOCO Wireless Client
without any special wireless networking software.
A wireless LAN can be configured for two different modes of operation. While each method has
its advantages, one of them may be better suited for your needs. Review the following
configurations to determine which mode is best for you.
3-2 Peer-to-Peer Group
A Peer-to-Peer group (also known as an Ad-Hoc network) is the simplest to deploy and is ideal
for small offices. Peer-to-Peer Group can be comprised of two or more wireless client configured
to communicate with one another. Peer-to-Peer Group clients communicate directly with each
other without using an access point (AP). As a user on this type of network, you are able to
quickly build up a wireless network in order to share files with other employees, print to a shared
office printer, and access the Internet through a single shared connection.
Ad-hoc networking is cost effective, because no other devices components are needed (such as
access points, hubs or routers) in order to setup a network. However, with Ad-Hoc networking,
your computer is only able to communicate with other nearby wireless clients.
By using the off-the-shelf peer-to-peer network operating systems, each computer can
dynamically connect and reconnect to the others with no additional configuration, as illustrated in
Figure 3-1 in next page.
ORiNOCO Wireless Client User Guide
Chapter 3 Wireless Topologies 18
Figure 3-1 Peer-to-Peer Group
The ORiNOCO Wireless Client can communicate with an 802.11a, 802.11a 2X Turbo, 802.11b or
802.11g Peer-to-Peer Group (but it can not dynamically switch between the two). Therefore, you
must manually configure the card to use one specific radio mode.
3-3 Access Point Infrastructure
Many companies have an existing Ethernet or wired LAN infrastructure and want to be able to
extend that capability to wireless nodes. This is accomplished by installing one or more Access
Points on the Ethernet network. Access Points are devices that communicate with both the
Ethernet network and the wireless network.
An Access Point network is also referred to as an Infrastructure network. The key difference
between an Infrastructure network and an Ad-Hoc network is the addition of one extra
element—the Access Point. The Access Point serves as the focal point for all data traffic on your
wireless network, optimally managing all wireless data transactions.
Additionally, the wireless Infrastructure can provide access to an existing wired LAN. This link
allows computers on the wireless LAN to access the other wired LAN’s resources and tools,
including Internet access, email delivery, file transfer, and printer sharing.
ORiNOCO Wireless Client User Guide
Chapter 3 Wireless Topologies 19
You can use the ORiNOCO Wireless Client to communicate with 802.11a Access Points,
802.11g Access Points, 802.11b Access Points, or a combination of Access Point types. The
card is compatible with 802.11a, 802.11g, or 802.11b Access Points from any vendor, including
Proxim’s ORiNOCO and Harmony Access Point products.
3-3-1 Connecting to a Single AP
Figure 3-2 depicts an ORiNOCO network that uses a single Access Point (AP); in this example,
the Access Point is an ORiNOCO AP- 2000 (with an ORiNOCO 802.11g card installed)
Figure 3-2 Communicating with a Single 802.11g Access Point
3-3-2 Roaming Between Multiple APs
For larger environments, the ORiNOCO Wireless Client may roam from one Access Point to
another while maintaining the same network connection. The Access Points establish coverage
areas or cells similar in concept to those of a cellular phone network. The card will connect to any
Access Point that is within range.
The ORiNOCO Wireless Client supports roaming between APs of the same type (for example,
from one 802.11a AP to another) or roaming between APs of different types (for example, from
an 802.11a AP to an 802.11g AP). Figure 3-3 illustrates roaming between APs of the same radio
type.
ORiNOCO Wireless Client User Guide
Chapter 3 Wireless Topologies 20
Figure 3-3 Roaming Between APs of the Same Radio Type
Figure 3-4 illustrates roaming between APs of different radio types:
Figure 3-4 Roaming Between APs of Different Radio Types
In either case, each Access Point within a roaming network must have a unique, independent
Channel, but all must have the same Network Name and security settings.
Mobile clients equipped with an ORiNOCO Wireless Client have Network Type set to “Access
Point” and have the same Network Name and security settings as the Access Points.
Alternatively, the mobile client’s Network Name may be “any”; this setting lets the client
associate with any available Access Point, regardless of the Access Point’s Network Name (this
assumes that the AP is not a closed system).
ORiNOCO Wireless Client User Guide
Chapter 3 Wireless Topologies 21
As the mobile client seamlessly switches from cell to cell, its network connectivity is preserved.
The user can move freely between the Access Points in the network. When the roaming client
leaves the transmission range of one Access Point, the card automatically detects the other
Access Point(s) in the same vicinity to continue the network connection.
3-3-3 Guidelines for Roaming
u An ORiNOCO Wireless Client can roam between 802.11a Access Points, 802.11g Access
Points and 802.11b Access Points.
u All 802.11a, 802.11b and 802.11g Access Points that a client will roam between must have the
same Network Name. Depending on the Wireless Mode selection, a user can roam among
802.11a, 802.11a 2X Turbo, 802.11g and 802.11b Access Points.
u All workstations with ORiNOCO Wireless Clients installed must use either a Network Name of
“any” or the same Network Name as the Access Points that they will roam between (this
assumes that the AP is not a closed system; see “Network Name” for more information).
u All Access Points and ORiNOCO Wireless Clients must have the same security settings to
communicate.
u The Access Points’ cells must overlap to ensure that there are no gaps in coverage and to
ensure that the roaming client will always have a connection available.
u Access Points installed in the same vicinity that use the same frequency band (2.4 or 5 GHz)
should each use a unique, independent Channel to avoid potential interference.
u Access Points that use the same Channel should be installed as far away from each other as
possible to reduce potential interference.
