Introduction
Overview
The Enterasys Networks Wireless Access Point 3000 is an IEEE 802.11a/b/g (RBT3K‐AG and
RBT3K‐AG‐G), or an IEEE 802.11b/g only (RBT3K‐1G), access point that provides transparent,
wireless high‐speed data communications between the wired LAN and fixed, portable or mobile
devices equipped with an 802.11a, 802.11b or 802.11g wireless adapter.
This solution offers fast, reliable wireless connectivity with considerable cost savings over wired
LANs (which include long‐term maintenance overhead for cabling). Using 802.11a, 802.11b, and
802.11g technology, this access point can easily replace a 10 Mbps Ethernet connection or seamless
integration into a 10/100 Mbps Ethernet LAN.
In addition, the access point offers full network management capabilities through an easy to
configure Web interface, and a command line interface for initial configuration and
troubleshooting.
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).
