Chapter 1: Introduction
The Dual-band Outdoor Access Point / Bridge system provides point-to-point or
point-to-multipoint bridge links between remote Ethernet LANs, and wireless access
point services for clients in the local LAN area.

OAP6626A
– Includes an integrated high-gain antenna for the 802.11a radio and
can be configured to operate as a “Master” or “Slave” bridge in point-to-multipoint
configurations, or provide a high-speed point-to-point wireless link between two
sites that can be up to 15.4 km (9.6 miles) apart. Up to two 5 GHz and two 2.4 GHz
antennas con be connected to the uinit. The 802.11b/g radio requires an external
antenna option. It supports wireless bridge connections to as many as 16
OAP6626A units configured as slaves.
The unit is housed in a weatherproof enclosure for mounting outdoors and includes
its own brackets for attaching to a wall, pole, radio mast, or tower structure. It is
powered through its Ethernet cable connection from a power injector module that is
installed indoors.
The wireless bridge system offers a fast, reliable, and cost-effective solution for
connectivity between remote Ethernet wired LANs or to provide Internet access to
an isolated site. The system is also easy to install and operate, ideal for situations
where a wired link may be difficult or expensive to deploy. The wireless bridge
connection provides data rates of up to 108 Mbps.
In addition, both wireless bridge models offer full network management capabilities
through an easy-to-use web interface, a command-line interface, and support for
Simple Network Management Protocol (SNMP) tools.
Radio Characteristics
– The IEEE 802.11a and 802.11g standards use a radio
modulation technique known as Orthogonal Frequency Division Multiplexing
(OFDM), and a shared collision domain (CSMA/CA). The 802.11a standard operates
in the 5 GHz Unlicensed National Information Infrastructure (UNII) band, and the
802.11g standard in the 2.4 GHz band.
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) and Complementary Code Keying (CCK) modulation technology
to achieve a communication rate of up to 11 Mbps.
The wireless bridge provides a 54 Mbps half-duplex connection for each active
channel (up to 108 Mbps in turbo mode on the 802.11a interface).
