WIRELESS NETWORK USB ADAPTER
1.1 Product Overview
The MODECOM 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 specifi cation, 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 benefi t 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 offi ce, the Wireless LAN Card reduces, or eliminates in some cases, the need to setup wired LAN
networks in the offi ce or home offi ce, 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 offi ce.
With the advent of notebook computers and an increasingly mobile computing society, the need for wireless
networking fi nds 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
