Introduction
The Business Access Point 120 is an IEEE 802.11a, 802.11b/g, and
Super a/g access point that provides transparent, wireless high-speed
data communications between the wired LAN and fixed or mobile devices
equipped with either an 802.11a or 802.11b/g wireless adapter, or both.
This solution offers fast, reliable wireless connectivity with considerable cost
savings over wired LANs (which include long-term maintenance overhead
for cabling).

BAP120 Fundamentals
Understanding the fundamentals of the BAP120 helps you set up, configure,
and use the BAP120.

BAP120 functions
The access point supports up to four Virtual Access Points (VAP) per
physical radio interface, that is four on the 802.11a radio and four on the
802.11b/g radio. Using this access point, traffic can be separated for
different user groups using an access point that services one area. For
each VAP, different security settings, Virtual Local Area Network (VLAN)
assignments, and other parameters can be applied.
Each radio interface on the access point can operate in one of four modes:
•Access Point – Providing connectivity to wireless clients in the service
area.
•Repeater – Providing an extended link to a remote access point from
the wired LAN. In this mode, the access point does not have a cable
connection to the wired Ethernet LAN. In this mode, at least one access
point must have wired connectivity to enable the signal to repeat to the
next unwired access point.
•Bridge – Providing links to access points operating in Bridge or Root
Bridge mode and thereby connecting other wired LAN segments.
•Root Bridge – Providing links to other access points operating in Bridge
mode and thereby connecting other wired LAN segments. Only one unit
in the wireless bridge network can be set to Root Bridge mode.

10 BAP120 Fundamentals
In addition, the access point offers full network management capabilities
through an easy to configure web interface, and support for Simple Network
Management Protocol tools.
Radio characteristics
The IEEE 802.11a/g standard uses a radio modulation technique known
as Orthogonal Frequency Division Multiplexing (OFDM), and a shared
collision domain (CSMA/CA). It operates at the 5 GHz Unlicensed National
Information Infrastructure (UNII) band for connections to 802.11a clients,
and at 2.4 GHz for connections to 802.11b/g clients.
IEEE 802.11b includes backward compatibility with the IEEE 802.11g
standard. IEEE 802.11b/g also operates at 2.4 GHz, but uses Direct
Sequence Spread Spectrum (DSSS) and Complementary Code Keying
(CCK) modulation technology to achieve a communication rate of up to
11 Mbps.
The access point supports a 54 Mbps half-duplex connection to Ethernet
networks for each active channel (or up to 108 Mbps when using turbo
mode on the 802.11a interface). The access point also supports Super A for
108 Mb/s on 802.11a mode and Super G for 108 Mb/s on 802.11g mode.
BAP120 user interfaces
You can manage the switch using one of the following:
•Web-based management – You can manage the network from the
World Wide Web. Access the Web-based Graphical User Interface
(GUI) through the HTML-based browser located on your network. Using
the GUI, you can configure, monitor, and maintain your network through
Web browsers. You can also download software using the Web.
• Business Element Manager – The Element Manager is a client-based
management application that runs on a Windows computer. Using the
Element Manager you can connect to BAP120 Series devices over an
IP network. It is used to configure, administer, and monitor BAP120
Series devices.
