Introduction
Thank you for choosing the Wireless-G Exterior Access
Point with Power Over Ethernet.
The Linksys Wireless-G Exterior Access Point with Power
Over Ethernet lets you connect Wireless-G (802.11g) or
Wireless-B (802.11b) devices to your wired network so you
can add PCs to the network with no cabling hassle. This
weather-proof Access Point creates a “wireless bubble” in
exterior spaces, like patios, pool areas, and outdoor cafés.
Power over Ethernet support makes it easy to install, and
you can create multiple SSIDs that connect to individual
VLANs to keep your traffic separated.
It’s also perfect for use as a bridge, a kind of “cable-less
cable” to connect remote areas together. Maybe your
warehouse is in a separate building from your offices. Or
maybe you need to connect the separate buildings of a
college campus. With one Wireless-G Exterior Access Point
on each building, you’re connected with no cable to run.
The exterior-rated case protects the access point, and
contains an internal antenna.
To protect your data and privacy, the Wireless-G Exterior
Access Point with Power Over Ethernet supports both
Wired Equivalent Privacy (WEP) and the industrial-strength
wireless security of Wi-Fi Protected Access™ (WPA),
encoding all your wireless transmissions with powerful
encryption. The MAC Address filter lets you decide exactly
who has access to your wireless network, and advanced
logging keeps you appraised. Configuration is a snap with
the web browser-based configuration utility.
The Linksys Wireless-G Exterior Access Point with Power
Over Ethernet is the best way to add wireless access to the
outdoor areas of your home or business.

Planning Your Wireless Network

Chapter 2:
Planning Your Wireless
Network
Network Topology
A wireless network is a group of computers, each equipped
with one or more wireless adapters. Computers in a
wireless network must be configured to share the same
radio channel to talk to each other. Several PCs equipped
with wireless cards or adapters can communicate with
each other to form an ad-hoc network without the use of
an access point.
Linksys wireless adapters also provide access to a wired
network when using an access point or wireless router.
An integrated wireless and wired network is called an
infrastructure network. Each wireless PC in an infrastructure
network can talk to any computer in a wired or wireless
network via the access point or wireless router.
An infrastructure configuration extends the accessibility
of a wireless PC to a wired network, and may double the
effective wireless transmission range for two wireless
adapter PCs. Since an access point is able to forward data
within a network, the effective transmission range in an
infrastructure network may be doubled (depending on
antenna characteristics).
Roaming
Infrastructure mode also supports roaming capabilities
for mobile users. Roaming means that you can move your
wireless PC within your network and the access points
will pick up the wireless PC’s signal, providing that they
both share the same wireless channel, SSID, and wireless
security settings.
Before you consider roaming, choose a feasible radio
channel and optimum access point position. Proper access
point positioning combined with a clear radio signal will
greatly enhance performance.
NOTE:
Spanning Tree Protocol should be
disabled on the switches connecting to the APs
to allow roaming to work without disruption.
Network Layout
The Access Point has been designed for use with 802.11g
and 802.11b products, such as the Notebook Adapters
for your laptop computers, PCI Adapters for your desktop
PCs, and USB Adapters.
These wireless products can also communicate with a
802.11g or 802.11b Wireless PrintServer.
To link your wired network with your wireless network,
connect the Access Point’s Ethernet network port to any
switch or router with Power over Ethernet (PoE)—or a PoE
injector, such as the Linksys WAPPOE or WAPPOE12.
NOTE:
12 VDC on WAPPOE12 is for the splitter
output. Both PoE Injectors provide 48 VDC
power output.

Example of a Simple Wireless Network
Example of Simple Wireless Network
The
above
diagram
shows
a
typical
infrastructure
wireless network setup. The Wireless Access Points are
connecting to a Linksys switch that provides power to
the Access Points. Each Access Point can connect multiple
wireless devices to the network. This network will provide
connectivity among wireless network devices and PCs
that have a wired connection to the switch.
The switch then can connect to a router that can connect
to an ISP for Internet access.

Product Overview
Front Panel
The Access Point’s LEDs, where information about network
activity is displayed, are located on the front panel.
Front Panel
Power
(Green) The Power LED lights up when
the Access Point is powered on.
Wired
(Green) The Wired LED lights up when
the Access Point is successfully connected to a
device through the Ethernet network port. If the
Wired LED is flashing, the Access Point is actively
sending to or receiving data from one of the
devices over the Ethernet network port.
Wireless
(Green) The Wireless LED lights up
when the wireless module is active on the Access
Point. If the Wireless LED is flashing, the Access
Point is actively sending to or receiving data from
a wireless device.
Bottom Panel
The Ethernet network port is located on the bottom panel
of the Access Point.
Bottom Panel
Ethernet network port
The Ethernet network
port connects to Ethernet network devices, such
as a switch or router. The Access Point is powered
using Power Over Ethernet. If the switch or router
doesn’t support Power Over Ethernet, then a
Power Over Ethernet Injector must be installed.
Top Panel
The antenna port is located on the top panel of the Access
Point.

Antenna Port
The Access Point has built-in,
1x2 MIMO 9dBi directional antennas. It also has
a reverse polarity female N-type antenna port
for an optional, high-gain external antenna
such as the HGA9N. One of the two internal
antennas will be disabled automatically when
an external antenna is connected.

Reset Button
There are two ways to Reset the Access
Point’s factory defaults. Either press the Reset button, for
approximately ten seconds, or restore the defaults using
the Access Point’s web-based utility.
IMPORTANT:
Resetting the Access Point will
erase all of your settings (including wireless
security, IP address, and power output) and
replace them with the factory defaults. Do not
reset the Access Point if you want to retain these
settings.
Ground
Before you mount the Access Point, you must
ground the Access Point (to a large piece of metal) as a
precaution against electric shock.
The Antenna Pattern
The Wireless-G Exterior Access Point uses 1X2 MIMO (1Tx,
2Rx) so it has two built-in antennas. The right antenna is
the main antenna for Tx traffic. When an external antenna
is attached, the right antenna is disabled and the external
antenna is used for Tx traffic. Currently, only the HGA9N
(9dBi omni-directional antenna) is compatible with the
Wireless-G Exterior Access Point.

Radio Coverage of the Access Point to Client Devices
When using the Access Point to connect client devices,
adjust it so the client devices are on the same horizontal
plane as the Access Point and within a 3dB angle of
50 degrees. This will ensure the strongest signal and
maximum reach.
If the Access Point is used inside a building, put it in a
corner of the building for maximum coverage.
Access Point to Access Point (bridging) Radio Coverage
If the Access Point is used as a bridge or repeater, adjust
the Access Points so they face each other, this will ensure
the strongest signal and maximum reach.
Make sure that the orientation of the two Directional
Antennas is the same. The radio wave is polarized so a 90
degree rotation will result in no received power.
Due to its directional characteristics, the internal antenna
is ideal for point-to-point bridge mode or the spoke
side of point-to-multipoint bridge mode. An external
omni-directional antenna (e.g. HGA9N) is recommended
for repeater mode applications.
