Introduction
The DWL-1750 conforms to the 802.11 standard and covers a large operating
distance, providing an 11Mbps* outdoor WLAN which enables users to access
the Internet or an organization’s network.
The D-Link AirPremier DWL-1750 features a die-cast watertight housing and
a built-in lightning protector to protect it from harsh environmental conditions,
including extreme variance in temperature. It also includes Power over Ethernet
(PoE) and a unique outdoor remote-mounted design for easy installation.
The DWL-1750 is suitable for manufacturing plants, industrial sites, military
bases, universities, hotels, airports and golf courses.
With a built-in firewall, the DWL-1750 can operate as a NAT inbound virtual
server and provides IP based access control. Denial of Service (DoS) protection
is also included with the DWL-1750 to prevent the wireless network from being
hacked. The DWL-1750 is easily managed via a web-based user interface,
Telnet, or RS-232 console configuration. The DWL-1750 can also be managed
remotely through SNMP (MIB I & MIB II) support.

System Requirements for Configuration:
*”Maximum wireless signal rate based on IEEE Standard 802.11b specifications. Actual data throughput will
vary. Network conditions and environmental factors, including volume of network traffic, building materials
and construction, and network overhead lower actual data throughput rate.”

Grounding
Outdoor Installation
The DWL-1750 can be mounted on the side of a building or mounted to a mast
as shown above. A wall mount is a convenient location if the roof overhang is not
excessive and/or the location is high enough to provide a clear line of sight.
A safety grounding system is necessary to protect your outdoor
installation from lightning strikes and the build-up of static electricity.
Direct grounding of the antenna mast and the DWL-1750 is very
important. The grounding system must comply with the National
Electrical Code and the safety standards that apply in your country.
Always check with a qualified electrician if you do not know how to
properly ground the DWL-1750.
This product should be installed ONLY by experienced, professional
installers who are familiar with local building and safety codes, and
wherever applicable, are licensed by the appropriate authorities.
Failure to do so may void the warranty and may expose the user or
the service provider to legal and financial liabilities.

The construction of the mast must be of a sturdy, weatherproof and
no corrosive material like examples of galvanized or stainless steel
construction pipe.
Typical diameter of the mast should be between 35 mm (1.4 in.) and
41 mm (1.625 in.). Subjecting to the type of antenna that you intend
to install other diameters may be possible as well.
The height of the antenna mast must be sufficient to allow the
antenna to be installed at least 1.5 m (5 ft.) above the peak of roof.
If the roof is metal, then the height of the antenna should be a
minimum of 3 m (10 ft) above the roof.
The mast or wall-bracket must be free from any substance that may
avoid a good electrical connection with the antenna; for example,
paint.
Antenna Mast Requirements
To accommodate the outdoor antennas, the antenna mast must satisfy the
following requirements:
Antenna Alignment
For optimal performance of your wireless link, make sure that the antennas
are properly aligned (facing one another “eye-to-eye”). To align the antennas:
Use a pair of binoculars and/or a map of the area and compass to
point the antennas to one another.
Use the Utility - “Wireless Link Info” in the Web Configure as
described in the “Utility” section to analyze the radio link quality. The
“Wireless Link Info” will enable you to display the levels of signal
strength and link quality. Looking at the Wireless Link Info screen,
you can interactively optimize antenna alignment if required, by
making small modifications in the antenna orientation.
Alternatively, consult a professional Antenna Installation Service to
optimize the antenna alignment.
Omni-directional antennas are characterized by a wide radiation
pattern. Therefore alignment of this type of antennas is less critical
than for directional antennas.
