1.1 Product Overview
The Mode Com MC-105USB 802.11b/g Wireless LAN Card gives you the freedom of secure high-speed com-
munications with other PCs without the need for interconnecting wires. You can even connect in to other LAN
infrastructures such as your company’s internal Ethernet LAN or your own home network. The antenna and de-
sign of the Wireless LAN Card gives you unmatched sensitivity which means your system will remain connec-
ted to other wireless PCs at high speeds for longer distances.
The Wireless LAN Card operates according to the IEEE 802.11b/g Wireless LAN specification, for wireless data
communications at speeds up to 54Mbps (Megabits per second). IEEE 802.11b/g operates on frequencies in
the 2.4GHz range using OFDM (Orthogonal Frequency Division Multiplexing) technology.
Backed by international standards and the IEEE organization, IT departments and end-users alike benefit from
the reliability and interoperability of products based on these standards. From an investment point of view, it
makes good business sense investing in technology that will be support worldwide for many years to come
(unlike technologies not backed by international communications standards). Whether you are running a com-
pany or a home office, the Wireless LAN Card reduces, or eliminates in some cases, the need to setup wired LAN
networks in the office or home office, eliminating costs associated with wiring rooms and buildings.

2. Wireless Network Concepts
For the past few decades, wired Local Area Networks (LAN) or more commonly know as Ethernet, have provi-
ded a seamless way of connecting and communicating with multiple PCs, desktops, laptop/notebooks, servers
as well as a host of other peripherals, including printers, scanners, etc. LANs have served us well in environ-
ments where users were not mobile or had little need to access data other than in their office.
With the advent of notebook computers and an increasingly mobile computing society, the need for wireless
networking finds more applications with each passing day. Wireless LANs have evolved to meet the needs of
mobile computing and are becoming very popular as compatibility, reliability and familiarity increases and
equipment costs decrease.
Wireless LANs (WLAN) allow users to roam freely about a network taking their computers with them while
still maintaining a networking connection. In essence, WLANs are an extension of wired LAN networks, where
the critical need is data access and mobility. The tradeoffs are slower speeds (although quite satisfactory for
Internet and email access) and limited roaming distance, as dictated by the environment.
A basic WLAN network requires client nodes and access points, similar to a LAN with its clients and infrastructu-
re (switches, repeaters, etc.). The access point is the connection to the wired LAN network or a designated com-
puter device performing the supervisory function, while client nodes are typically WLAN adapters installed
in peripheral computing devices, such as notebooks, desktops, personal digital assistants (PDAs) and others.
Once a WLAN is setup, it acts like a wired LAN, using the same protocols designated for communicating via the
IEEE Ethernet standard.
2.1 Wireless LAN Network Modes
WLANs basically have two modes of operation:
• Ad-Hoc mode
• Infrastructure mode
Ad-Hoc Mode
An Ad-Hoc WLAN is created when two or more PCs equipped with Wireless LAN Cards (WLAN clients) are con-
figured to use the same radio channel and Network Name in the same area and can communicate freely with
each other, without the need for an Access Point to a hard-wired LAN network. Only PCs that use the same ra-
dio channel and network name can communicate over the Ad-Hoc network. This type of a network is a peer-to-
-peer relationship where each computer talks directly to one another with no one PC being dominant.

Figure 2 Ad-Hoc Mode: Two or More PCs with 802.11b/g Wireless LAN Cards Configured to Same Radio
Channel and Network Name
Infrastructure Mode
When a WLAN access point is introduced into the WLAN, the access point and its clients (each PC) comprise
a Basic Service Set (BSS), whereby the access point serves as the connection to the wired LAN for each client.
Clients within the same BSS do not directly communicate between each other; rather they communicate to the
AP that routes the data to the appropriate destination.
The access point bridges both wired and wireless networks, allowing wired and wireless client communication.
This arrangement of WLAN access points and clients is commonly referred to as Infrastructure mode. An access
point also extends the range of the WLAN, double over that of client only networks because the access point
is able to forward data within its BSS.
Infrastructure mode enables the network clients to freely roam, once an ESS (Extended Service Set) is establi-
shed.
With all clients using the same radio channel and ESS ID (sometimes referred to as SSID which is a given name
to the network), users are fully mobile within the range of the access point signal. Access points should be situ-
ated in location to deliver the largest range of signals, with minimal interference. Best performance and signal
quality is often affected by building structures, walls, etc., and may require some trial-and-error to identify the
best location for access points.

2.2 Planning Your New Wireless Network
First, determine what components (WLAN cards, access points) and what kind of network will be created (Ad-
Hoc, Infrastructure mode). Then select your network name (SSID), WEP key (security password) and channel
number (1 through 11 in US, 1 through 13 in Europe and 1 through 14 in Japan). All members of the wireless
LAN will have to configure their PCs to the same SSID, WEP and Channel number to talk to each other. SSID,
WEP key and channel number are essential to understanding and creating a successful wireless network.
These concepts are explained in the following paragraphs.
SSID
A wireless network requires a BSS or ESS to operate and a name associated with it. SSID literally stands for a ne-
twork name for use with that Service Set of clients and access points if so set up. All computers must have the
same SSID as the network in order to communicate over the new network. The SSID name can be any name
such as “wireless_lan”, “Bob’s domain”, or “AbCdE123”, and can include numbers as well as be case-sensitive. If
the exact SSID name is not used, then that wireless client cannot logon into that network.
Operating Frequency (Channel)
IEEE 802.11b/g wireless LAN networks communicate using one of several available channels (each with a dif-
ferent operating frequency) to reduce the interference from other potential sources or users of that channel.
Depending on the country where the network is being set up, you may have a choice of up to 14 channels
available. In the US, channels 1 through 11 are defined for use in the 2.4GHz spectrum used by 802.11b/g. In
Europe, channels 12 and 13 are added, while Japan can have up to 14 channels. Channels 1, 6 and 11 are the
most commonly used channels in the US.
For your network, choose a channel that offers little interference and configure all users of this network to the
same channel.

WEP Key
WEP provides for two levels of security encryption based on the length of bits in a key called a Shared Key. A
40-bit key (which is 5 characters) provides some security; this can be a key like “12345” or “MyLAN”. A 104-bit
key is also available and provides more robust security. A 13-character key is required for 104-bit security. Keys
can be in ASCII characters or Hexadecimal. ASCII characters are those used in computers and include all typew-
ritten characters including the alphabet and numbers, as well as */”()[] characters. Hexadecimal characters are
limited to the numbers 0-9 and the first 6 letters of the alphabet a-f.
Table 1 WEP Key Examples
Note: Every key has an added 24-bit provided by the card, which are set by the manufacturer and
not user modifiable. This manual uses the terms 40-bit and 104-bit to represent 64-bit and
128-bit keys respectively. This is the most commonly used terminology in the industry.
The WEP key for your wireless LAN network is another form of password. Like passwords, certain combinations
of passwords are not recommended for use (such as 01234, abcde, or publicly known information like your of-
fice phone number, dog’s name, etc.). Protect your WEP key as you would a password.
Note: If you access other networks with already predefined keys, always enter them exactly as
they appear taking note of lower and upper case letters.
Any computer accessing a wireless network with WEP enabled not only requires the same SSID but also the
same WEP key in order to have access.
With the above factors decided, physical placement of the components will be critical. The maximum range of
the wireless LAN will often be decided by the type of environment it is located in and, if in different rooms, by
how many obstacles are in the way which reduces the range of the wireless adapters. Often, Ad-Hoc mode will
require the wireless clients to be in closer range of each other than Infrastructure type networks. The Wireless
LAN Card can operate at up to 100m indoors and up to 300m outdoors, although the physical environment
(walls, floors, ceilings, etc.) will limit the range of wireless signals.
WEP Key size Number of Digits Example
40-bit (also called 64-bit) 5 (ASCII) 12345, MyLAN, 78E*5
10 (Hexadecimal) 1A37FB458C
104-bit (also called 128-bit) 13 (ASCII) 1234567890123,This_is_MyLAN
