The SMC EliteConnect Universal 2.4GHz/5GHz Wireless
Dual-Band Outdoor Access Point/Bridge system consists of two
models that provide 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:
•SMC2888W-S – Includes an integrated high-gain antenna for
the 802.11a radio and is designed to operate as a “Slave”
bridge in point-to-multipoint configurations, or provide a
high-speed point-to-point wireless link between two sites. The
802.11b/g radio requires an external antenna option.
•SMC2888W-M – Provides only external antenna options and
is designed to operate as the “Master” bridge in
point-to-multipoint configurations, supporting wireless bridge
connections to as many as 16 SMC2888W-S Slave units.
Each model 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. The unit 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.
1-1
Introduction
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).

Hardware Description
Integrated High-Gain Antenna
The SMC2888W-S wireless bridge includes an integrated
high-gain (17 dBi) flat-panel antenna for 5 GHz operation.
External Antenna Options
The SMC2888W-M Master bridge unit does not include an
integrated antenna, but provides various external antenna options
for both 5 GHz and 2.4 GHz operation. In a point-to-multipoint
configuration, an external high-gain omnidirectional, sector, or
high-gain panel antenna can be attached to communicate with
bridges spread over a wide area.
External antennas connect to the N-type RF connectors on the
wireless bridge using the provided coaxial cables.
Ethernet Port
The wireless bridge has one 10BASE-T/100BASE-TX 8-pin DIN
port that connects to the power injector module using the
included Ethernet cable. The Ethernet port connection provides
power to the wireless bridge as well as a data link to the local
network.
The wireless bridge appears as an Ethernet node and performs a
bridging function by moving packets from the wired LAN to the
remote end of the wireless bridge link.
Note: The power injector module does not support Power over Ethernet
(PoE) based on the IEEE 802.3af standard. The wireless bridge
unit must always be powered on by being connected to the power
injector module.
1-5
Introduction
Power Injector Module
The wireless bridge receives power through its network cable
connection using power-over-Ethernet technology. A power
injector module is included in the wireless bridge package and
provides two RJ-45 Ethernet ports, one for connecting to the
wireless bridge (Output), and the other for connecting to a local
LAN switch (Input).
The Input port uses an MDI (i.e., internal straight-through) pin
configuration. You can therefore use straight-through twisted-pair
cable to connect this port to most network interconnection
devices such as a switch or router that provide MDI-X ports.
However, when connecting the access point to a workstation or
other device that does not have MDI-X ports, you must use
crossover twisted-pair cable.

(Hidden)
The wireless bridge does not have a power switch. It is powered
on when its Ethernet port is connected to the power injector
module, and the power injector module is connected to an AC
power source. The power injector includes one LED indicator that
turns on when AC power is applied.

Hardware Description
The power injector module automatically adjusts to any AC
voltage between 100-240 volts at 50 or 60 Hz. No voltage range
settings are required.
Warning: The power injector module is designed for indoor use only.
Never mount the power injector outside with the wireless
bridge unit.
Receive Signal Strength Indicator (RSSI) BNC
Connector
The RSSI connector provides an output voltage that is
proportional to the received radio signal strength. A DC voltmeter
can be connected this port to assist in aligning the antennas at
both ends of a wireless bridge link.
Grounding Point
Even though the wireless bridge includes its own built-in lightning
protection, it is important that the unit is properly connected to
ground. A grounding screw is provided for attaching a ground wire
to the unit.
Wall- and Pole-Mounting Bracket Kits
The wireless bridge includes bracket kits that can be used to
mount the bridge to a wall, pole, radio mast, or part of a tower
structure.
