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 802.11g clients.
IEEE 802.11g includes backward compatibility with the IEEE 802.11b standard. IEEE 802.11b also
operates at 2.4 GHz, but uses Direct Sequence Spread Spectrum (DSSS) modulation technology to
achieve a communication rate of up to 11 Mbps.
The access point also supports a 54 Mbps half-duplex connection to Ethernet networks for each
active channel (up to 108 Mbps in turbo mode on the 802.11a interface).
Management Options
The IronPoint 200 contains LEDs for “at-a- glance” monitoring of wireless and network port status. It
also includes a built-in network management agent that allows the access point to be managed in-
band using SNMP, with a web browser, or remotely via Telnet. The access point provides an RS-232
DCE serial port (DB-9 connector) on the front panel for out-of-band management. A PC may be
connected to this port
for configuration and monitoring out-of band via a straight-through serial cable.
(See “Console Port Pin Assignments” on page B-3 for wiring options.)
For a detailed description of the access point’s management features, refer to the Foundry
IronPoint 200 User Guide.
