INTRODUCTION

1.1 AirStation Broadband Router
Access Point (WBR-G54)1

Welcome to AirStation, the easy way to
ultra fast wireless networking. Bring your
wireless home network closer to your enter­tainment!

This book, which describes the most com­mon congurations, introduces you to the
High Speed AirStation Broadband router
access point, and will help you connect to
your network quickly.

The High Speed AirStation Broadband
Router Access Point (AP), WBR-G54, is a
4-port router wireless small/medium busi­ness (SMB) network device that complies
with the IEEE 802.11b (Revision B) standard
and the IEEE 802.11g draft specication on
wireless LANs with turbo data rate. IEEE

802.11g technology features longer range
than IEEE 802.11a and greater bandwidth
with data rates up to 54 Mbps in the
turbo mode. WBR-G54 supports enhanced
built-in rewall functions and it is used
as a multi-functional router/link between
wired and wireless LAN PCs. The WBR-G54
incorporates features of wired and wireless
networking environments.

Summary of the AirStation WBR-G54 fea­tures:

• Wi-Fi™ (Wireless Fidelity) certied by
the Wi-Fi Alliance. AirStation will com­municate with other IEEE 802.11b/Wi-Fi
compliant wireless LAN products.

• Automatic Transmit Rate Select mechanism

transmits at speeds of 24, 12, 11, 5.5, 2 and
1 Mbps.

• Supports turbo mode of 36, 48 and up to

54 Mbps.

• Ability to set a xed data rate for faster

than 11 Mbps ignoring 802.11b legacy de­vices.

• DHCP client/server function.

• Auto roaming, supports seamless roaming

over multiple channels.

• Auto VPN setup, for secure communications.

• Additional Firewall Functions - DMZ, intru­sion detection and notication

• Up to 128bit Wired Equivalent Privacy (WEP)

data encryption (future support for WPA and
TKIP).

• Packet Filtering for eliminating unwanted
communications.

• SOHO/SMB routing and rewall func­tions provide a safer private networking
environment, including MS NetMeeting
and MSN-Messenger.

• Syslog transmits some or all system
activities to a central Syslog server.

• Extended range, with optional add-on
antennas.

• Auto Media Dependent Interface/
Crossover (MDI/X) port, allows connec­tion by standard and crossover CAT5
cables.

• Supports Universal Plug and Play
(UPnP).

Other features to be supported by up-

grades:

• EAP-TLS, expanding the 802.1x authen­tication method.

• PPPoE multi-session, for use with mul­tiple stations.

1.2 AirStation Wireless Network

• Buffalo’s easy connection method and
picture guided setup instruction.

• Broadband router static and dynamic

routing methods between WAN and
LAN based on updated routing tables.
An economical way to bridge multiple
networks.

• Optional external antennas for boost­ing range and signal quality.

• Resistance to environmental condi­tions.

1.3 Home Networking 1

For the future home entertainment
applications that carry hard drives for
storing hundreds of titles, IEEE 802.11g
can transmit three channels of CD-qual­ity voice, or DVD-quality video to every
room in the home simultaneously.
Buffalo’s AirStation wireless access point
enables sharing broadband at your
ngertips. All you need to do is connect
the AirStation to a DSL or CATV modem
to:

• Share les and printers

• Access and share the Internet

• Share home entertainment system

1.4 SOHO/SMB Networking

With high-speed DSL or CATV connections
readily available, many users can work
effectively from a home ofce, connected
securely to a corporate network. Buffalo’s
solutions are ideal for home networks
that require secure, high-speed access
to the corporate LAN. Tools that play an
integral part in Buffalo’s solutions include
VPN connectivity for secure access to
corporate resources, which enable the
remote employee to handle information
from clients or coworkers as if they were
in the ofce. IEEE 802.11g technology
enables anticipated data intensive ap­plications such as high security commu­nication and VoIP. Connect the Buffalo
AirStation Broadband router AP to a CATV
or DSL modem in order to:

• Share broadband access

• Share les and printers

• Bridge between multiple networks and
multiple PC platforms

• Provide easy and secure access to
home or company networks from re­mote locations

1.5 Buffalo Anywhere Networking

Mobile professionals can be productive
while traveling by accessing standards­based, secure, high-speed connections in
many hotel, airports, convention centers,
and even coffee shops. The WBR-G54
makes extending your LAN simple, secure,
scalable, and manageable, in part through
solutions like VPN, allowing mobile
professionals to take their ofces on the
road effortlessly. When no wired broad­band connections are available, wire­less solutions in public spaces coupled
with VPN can connect mobile workers to
their businesses. Buffalo’s access point
features make a home network system
accessible from anywhere.
