Figure 1: DWL- - -1800 Point to Multipoint Application
1 2 2 1. . . DWL-1800B (BU) Wireless Base Unit
The DWL-1800B is an IEEE 802.11b compliant base station that connects one or
more remote sites to a central server or Internet connection. In a point-to-multi-point
configuration the DWL- - -1800B is the central unit while in point to point
configurations it should be installed at one end of the link.
The DWL-1800B is the basic unit, equipped with an antenna integrated into the
front cover of the outdoor unit.

1 2 2 2. . . DWL-1800R (RB) Wireless Bridge
The DWL-1800 Wireless Bridge connects a remote Ethernet network to a central
network server or Internet site via a DWL-1800 Multipoint Base .
The maximum number of MAC addresses that the unit can handle at any specific
time is 1024 and the Aging algorithm is applied at all times.
When a station on the Ethernet LAN sends a message that is not destined for a local
station, the DWL- -1800R forwards the message to the DWL 1800B. When the
DWL- -1800B receives a message destined for a station on the DWL 1800R's LAN,
the DWL- -1800B wirelessly forwards it to the DWL 1800R. In this manner, the
DWL- -1800R and the DWL 1800B work together like a standard network bridge.
The first time each station on the DWL-1800R’s LAN sends a message, the station’s
address is registered by both the DWL- -1800R and the DWL 1800B. It is possible
for the DWL- -1800R and DWL 1800B to store all the addresses necessary to support
an entire LAN connected to a DWL-1800R.
The DWL-1800R is the basic unit, equipped with an antenna integrated into the
front cover of the outdoor unit.

Card (NIC).
2 3. Outdoor Installation Considerations
This chapter describes various considerations to take into account when planning an
outdoor installation including site selection, antenna alignment, antenna
polarization and cell size.
6
2 3 1. . Collocating DWL-1800 Outdoor Units
Up to three DWL-1800B units with integrated antennas (the exact number depends on
the number of non-overlapping channels available in the relevant regulatory domain)
can be collocated on the same building top or tower. Collocating more then three units
may decrease performance depending upon the type of antenna and its direction. Each
unit should be assigned to one of the non-overlapping channels: 1, 7, or 13 in ETSI or
1, 6 or 11 in FCC.
2 3 2. . Site Selection Factors
When selecting a location for outdoor units and external antennas, remember to take
into consideration the following guidelines:
?? Minimum distance between sites.
?? Maximum height above the ground.
?? Maximum line of sight clearance.
Path of Clearest Propagation
A propagation path is the path that signals traverse between the antennas of any two
units. The “line” between two antenna sites is an imaginary straight line, which may
be drawn between the two antennas. Any obstacles in the path of the “line” degrade
the propagation path. The best propagation path is, therefore, a clear line of sight
with good clearance between the “line” and any physical obstacle.
Physical Obstacles
Any buildings or other physic al structures such as trees, mountains or other
geographic features higher than the antenna and situated in the path between the two
sites can constitute obstructions and cause signal attenuation. Install outdoor
antennas high enough to avoid any obstacles, which may block the signal.
7
Path Loss
Path loss is determined mainly by several factors:
?? Distance between sites – Path loss is lower and system performance
better when distances between sites are shorter.
?? Clearance – Path loss is minimized when there exists a clear line of
sight. The number, location, size, and makeup of obstacles determine
their contribution to path loss.
?? Antenna height – Path loss is lower when antennas are positioned
higher. Antenna height is the distance from the imaginary line
connecting the antennas at the two sites to ground level. Ground level in
an open area is the actual ground. In dense urban areas, ground level is
the average height of the buildings between the antenna sites.
2 3 3. . Rooftop Installation
Rooftop installations offer several advantages:
?? Fewer obstacles in the path.
?? Improved performance due to greater height.
2 3 4. . Antennas for Outdoor Applications
The D- - - -Link AirPremier DWL 1800 series can be used in point to point or
point- -to multipoint configurations.
Point Point- -to
The DWL- -1800B/DWL 1800R is equipped with a directional antenna. The required
antenna gain depends on the required range and performance.
Point- -to Multipoint
Setting up a point- -to multipoint link requires the use of a base unit equipped with an
integrated antenna and at least two remote units also equipped with integrated
antennas.
8
2 3 5. . Antenna Polarization
Antenna polarization must be the same at both ends of the link. In most applications,
the preferred orientation is vertical polarization, which is best for above ground
propagation.
2 3 6. . Cell Size/Link Distance
Cell size is determined by the maximum possible distance between the DWL-1800B
and a DWL-1800R unit. For open outdoor areas with an unobstructed line of sight
between the BU-DWL- -1800B and the DWL 1800R units, the suggested maximum
distance is up to 6 miles (10Km) where ETSI is the regulatory domain and 15 Miles
(25 Km) where FCC is the regulatory domain.
2 3 7. . Using Outdoor Range Tables
Specific range tables, guidelines and information about extended cables can be
obtained from your local dealer or the D-Link central offices.
Outdoor installations must have a clear line- -of sight between antennas. Solid
obstacles such as buildings or hills can prevent the establishment of a link while
partial obstacles such as trees or traffic can reduce range. Extended coaxial cables
can cause an increase in signal loss and a reduction in range.
2 3 8. . Precautions
NOTE: Outdoor units and antennas should be installed ONLY by experienced antenna
installation professionals who are familiar with local building and safety codes
and, wherever applicable, are licensed by the appropriate government
regulatory authorities.
The system complies with the ETS 300 385 standard and is protected against
secondary lightning strikes when its outdoor unit is properly grounded
according to the applicable country-specific industry standards for protection
against lightning. The system complies with EN 61000- -4 5, test level 3 (2kV).
Failure to do so may void the D- -Link Air Premier DWL 1800 Product
Warranty and may expose the end user to legal and financial liabilities. D-Link
and its resellers or distributors are not liable for injury, damage or violation of
government regulations associated with the installation of detached antennas.
9
2 3 9. . Compliance with Radio Regulations
Regulations regarding maximum antenna gains vary from country to country. It is
the responsibility of the end user to operate within the limits of these regulations as
well as to ensure that the professional installer is aware of these regulations.
Violation of government regulations exposes the end user to legal and financial liabilities.
D-Link , its resellers and distributors shall not be liable for expense or damage incurred as
a result of installations that exceed local transmit power limitations.
2 4. Installing the Outdoor Unit
The outdoor unit can be secured to the pole using one of the following options:
?? Special brackets sets (supplied with each unit). There are two pairs of
screw holes on the units, allowing the use of the brackets with various
pole widths.
?? U- -bolts size A (inner installation holes, up to 2" pole).
?? U- -bolt size B (outside installation holes, up to 3" pole).
?? Metal bands (9/16” wide, minimum 12” long).
Figure 3 shows the locations of the holes, grooves and screw holes on the back of
the unit.
Figure 4 illustrates the method of installing a unit on a pole using the supplied
brackets.
NOTE: Make sure to install the unit with the bottom panel (the panel with the signal
strength bar and LEDs) facing downward.

grooves pointing outwards; these grooves are intended to allow fastening of the
screws with a screwdriver.
2 4 1. . Connecting the Ground and Antenna Cables
The Ground terminal (marked ) is located on the bottom panel of the outdoor unit.
1. Connect one end of the grounding cable to the Ground terminal and
connect the other end to a good ground connection.
2 4 2. . Connecting the Indoor- -to Outdoor Cable
1. Remove the two screws holding the waterproof seal to the outdoor unit
and remove the waterproof seal.
2. Unscrew the top nut from the waterproof seal.
Figure 5: The Waterproof Seal
12
3. Route a straight, uncrimped Ethernet cable (8-wire, 24 AWG) through
both the top nut and the waterproof seal.
NOTE: The 8-wire cable should be shielded.
4. Insert and crimp the RJ-45 connector. Refer to Appendix B for
instructions on preparing the RJ-45 cable connector.
5. Connect the Ethernet cable to the Outdoor unit RJ-45 connector.
6. Replace the waterproof seal and then the top nut. Make sure that the
external jack of the cable is well inside the waterproof seal to guarantee a
good seal.
7. Route the cable to the location selected for the Indoor unit.
2 5. Installing the Indoor Unit
Route the Indoor- -to Outdoor cable into the building so that it conveniently reaches
the indoor unit while avoiding interference sources. It is recommended that the
cable be a little longer then necessary. The cable is supplied open ended so it can be
conveniently threaded as shown into the building.
1. Remove the wall-mounting bracket clipped to the back of the indoor unit
and mount it on a wall as shown in Figure 6. Mount the indoor unit on
the mounting bracket.
2. Assemble an RJ-45 connector with a protective cover on the indoor side
of the Indoor- -to Outdoor cable. Refer to Appendix B for instructions on
preparing the RJ-45 cable connector.
3. Connect the Indoor- -to Outdoor cable to the Radio connector, located on
the top panel of the indoor unit shown in Figure 8 on page 14. The
Indoor- -to Outdoor cable should be connected to the unit before the unit
is connected to the mains power.

5. Verify that the yellow POWER LED located on the top panel is lit,
indicating that the unit is supplying power to the radio port.
Figure 8: Indoor Unit Top Panel
6. Connect the 10BaseT connector to the network. The cable connection
should be straight Ethernet if connecting the Indoor unit to a Hub and a
crossed cable if connecting it directly to a PC Network Interface Card
(NIC).
NOTE: The length of the Ethernet cable connecting the indoor unit to the
user's equipment, together with the length of the Indoor- -to Outdoor
cable, should not exceed 90 meters.
2 5 1. . Configuring Parameters
Before aligning the antenna, certain key parameters must be configured to
enable connectivity with linked units.
See Unit Configuration Mode on page 20 9 for more information.
2 5 2. . Antenna Alignment
Usually, low gain antennas do not require alignment due to their very wide radiation
pattern. High gain antennas, including the integral antenna of DWL-1800 units,
have a narrow beamwidth necessitating an alignment procedure in order to optimize
the link.
Check the antenna alignment by using the RSSI bar on the bottom panel of the
DWL-1800R unit.
To align the antenna:
1. Confirm that the units at both ends of the link are receiving power.
15
2. Synchronize the units by aligning the antennas at the central and remote
sites until maximum signal quality is obtained. Check the signal quality
RSSI bar on the bottom panel of the DWL-1800R. The first LED lights
red to indicate that the unit is working. The remaining nine LEDs light
green to indicate the signal strength. The stronger the signal, the more
LEDs are lit. Rotate the antenna to the left or right until you reach the
point of maximum RSSI reading. Make sure that at all times the front of
the antenna faces the general direction of the DWL-1800B.
