application illustrations of the Advanced Wireless 11g Router.

1-1 About The 11g Wireless Security Router

The 11g Wireless Security Router is a hybrid design product which combines Ethernet
technology and wireless access into a single stand-alone unit. The device allows yo u take
advantages of both mobility and fast connection. All PCs whenever on wireless LAN or
Ethernet LAN can share files, printers and other network resource. Moreover, all users
can share single account of Internet access by having this device connect to a DSL/Cable
modem.

Ethernet / Fast Ethernet

Ethernet is the most widely-used network access method, especially in a Local Area
Nnetwork (LAN) and is defined by the IEEE as the 802.3 standard. Normally, Ethernet is
a shared media LAN. All stations on the segment share the total bandwidth, which could
be 10Mbps (Ethernet), 100Mbps (Fast Ethernet), or 1000Mbps (Gigabit Ethernet). With
a switched Ethernet, each sender and receiver has the full bandwidth.
Fast Ethernet is defined as IEEE 802.3u standard, a high-speed version of Ethernet with
100Mbps transmission rate.

Wireless LAN

Wireless Local Area Network systems (WLANs) transmit and receive data through the
air by using radio frequency (RF). This offers some advantages like mobility, ease of
installation, and scalability over traditional wired systems.
Mobility: WLANs combine data connectivity with user mobility. This provides users
with access to network anywhere in their organization. For example, users can roam from
a conference room to their office without being disconnected from the LAN. This is
impossible with wired networks.
Ease of Installation: Eliminating the need to deploy network cable in walls and ceilings,
Installing WLANs is easy for novice and expert users alike.
Scalability: WLAN topologies are easy to change in various ways from peer-to-peer
networks for a small group of users to full infrastructure networks for hundreds of users
roaming over a broad area.
Wireless LAN is suitable for difficult-to-wire and frequently changing environments. It's
also an ideal solution for mobile workers to access network resource and for setting a
temporary LAN when necessary
Wireless LANs can be set as "Aad-hoc" network and "Infrastructure" network. Unlike
the "Aad-hoc network", where users on the LAN send data directly to each other, the
"Infrastructure" network includes an access point and users on the "Infrastructure"
