Quick Installation Guides
This Quick Installation Guide is intended for experienced installers and network administrators. Please refer to the D-Link AirPremier DWL-1800 Manual on the CD for further details and information regarding the installation procedures. The Base Unit Station DWL-1800B is a required product in all installations, wether PtP or PtMP architecture; the remote stations canâ€™t communicate to each others without DWL-1800B.
Outdoor units and antennas should be installed ONLY by
experienced 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 D-Link
product warranty and may expose the end user or the service provider to legal and financial liabilities. D-Link and its resellers or distributors are not liable for injury, damage or violation of regulations associated with the installation of outdoor units or antennas. System Description The products come in two options: the basic DWL-1800B (BU) and DWL-1800R (RB) units come with a high gain flat antenna integrated on the front cover of the Outdoor unit. In this model, the front cover also functions as a protective sun cover. The installation process should follow these general steps: 1.
Select an appropriate locations for the Outdoor unit, the antenna (if using an external antenna) and the Indoor unit.
Connect a ground cable between the Outdoor unit and an appropriate grounding point.
Remove the service box assembly of the Outdoor unit, unscrew the top nut and route the indoor-outdoor cable through the top nut and the service box. Assemble an RJ-45 connector on the cable, connect it to the Ethernet connector, replace the service box and tighten the nut. Make sure that the external jack of the cable is well inside the service box to guarantee a good sealing. Route the cable to the location selected for the Indoor unit. Preparing the Indoor-to- Outdoor Cable The Indoor-to-Outdoor cable provides pin-to-pin connection on both sides. It is supplied open-ended, to allow the installer to conveniently route the cable through the service box of the Outdoor unit and through a wall into the building. The following diagram shows the wire pair connections required for the Indoor-

Mount the Indoor unit. Assemble an RJ-45 connector with a protective cover on the indoor side of the Indoor-to-Outdoor cable and connect it to the Indoor unitâ€™s Radio port. Prepare the power cable (if supplied open ended) and use it to connect the Indoor unit to the AC mains.
Note: The Indoor unit should be connected to the power source only after it has been connected to the Outdoor unit.
Note: If the power cord supplied with the unit is open ended, connect to it a power plug appropriate to the country in which the unit is being installed. The color codes of the cable are: brown phase ~ blue neutral 0 yellow/green grounding The operating AC mains voltage of the Indoor unit is marked on the rear panel of the unit
Indoorunit Ethernet port to the Ethernet hub using a straight Ethernet
cable or directly to the PCâ€™s NIC using crossed cable.
Align the antenna and verify connectivity with the other unit(s). To perform antenna alignment: 1. Power on both units. 2. Synchronize the units by aligning the antennas at the main and remote sites until
maximum signal quality is obtained. Check the signal strength RSSI bar on the bottom panel of the DWL-1800R (RB) bottom panel. If the received signal quality is lower than expected for this antenna/range combination, change antenna height and verify RF cables connections. Verifying Correct Operation
To verify proper operation of the Outdoor unit, view the LED indicators located on the bottom panel of the unit as shown in the following table: Outdoor Unit LEDs Name Description Functionality

Note: The LINK LED indicates end-to-end connection between the outdoor unit and the Ethernet connection to the indoor unit. Quick Start to Wireless Networking Perform the following steps to configure a WLAN for the first time:
1. Physically connect the DWL-1800B/DWL-1800R units to the Ethernet LAN. Make sure they
are switched on. The D-Link AirPremier DWL-1800 wireless network will be up and running immediately. If you are content with the default settings of the DWL-1800B/DWL- 1800R units, you can stop right here. It is more likely however, that you want to assign different radio frequencies to each DWL-1800B/DWL-1800R, or impose some restrictions on the use of your wireless network.
2. To be able to manage the DWL-1800B/DWL-1800R units via SNMP, each DWL-
1800B/DWL-1800R needs a unique IP address. If you provide a DHCP or BOOTP service on your LAN (and have sufficient free IP addresses available) this will be taken care of automatically. If not, refer to User's Guide for further information on assigning IP addresses.
3. Use the D-Link AirPremier DWL-1800 Configuration utility to configure the network
settings according to your needs.
4. Select the radio channels of the DWL-1800B/DWL-1800R units according to your cell plan.
See the User's Guide for further details and information regarding cell planning and channel selection.
Preparing The Indoor To Outdoor Cable
The Indoor-to-Outdoor cable provides pin-to-pin connection on both sides. It is supplied open- ended at both sides, to allow the installer to conveniently route the cable into the waterproof seal off the Outdoor unit and through holes in walls. The figure below shows the wire pair connections required for the Indoor-to-Outdoor cable.
4 + 5
1 + 2
7 + 8
3 + 6
Use a standard crimp tool for RJ45 connectors to prepare the wires, insert them into the appropriate pins and use the crimp tool to crimp the connector. Make sure to do the following: a) Remove as smaller length as possible of the external jacket to verify that the external jacket
will be well inside the service box when connected to the Outdoor unit to ensure good sealing.
b) Take back the shield drain wire before inserting the cable into the RJ-45 connector, to
ensure a good connection with the connectorâ€™s shield after crimping.
Connecting the Indoor-to-Outdoor Cable
1. Remove the two screws holding the waterproof seal assembly to the Outdoor unit and
remove the waterproof seal.
2. Unscrew the top nut from the waterproof seal.
Routing the Indoor-to-Outdoor Cable through the Waterproof Seal
3. Route an uncrimped straight Ethernet cable (8-wire, 24 AWG pin-to-pin) through the top
nut and the waterproof seal. Note: The 8-wire cable should be shielded.
4. Insert and crimp an RJ45 connector. 5. Connect the cable to the outdoor unit RJ45 connector. 6. Replace the waterproof seal assembly to the Outdoor unit and then replace the top nut.
Make sure that the external jack of the cable is well inside the service box to guarantee a good sealing.
7. Route the cable to the location selected for the Indoor unit. 8. Assemble an RJ-45 connector with a protective cover on the indoor side of the Indoor-to-
Outdoor cable and connect it to the Indoor unitâ€™s Radio port.

DWL-1800 FAQ General Can the DWL-1800R indoor unit be placed outdoors?
It is not recommended. The DWL-1800 indoor units are specified to operate between 0Â°C and 40Â°C and is not weather proof so it is best to mount the DWL-1800R indoors or in a protective
cabinet. Do DWL-1800 units support 802.1Q VLAN?
Yes, but the support is limited to transparent operation. This means that the DWL-1800 does not take any action on 802.1Q frames, but will transparently pass them within a VLAN network. What is the maximum number of networked PCs the DWL-1800B/ DWL-1800R can learn?
1024 network MAC addresses can be learned by the DWL-1800B/DWL-1800R from the LAN side. Can the DWL-1800B/DWL-1800R be used for multi-point as well as point-to-point links?
Yes. The DWL-1800B can support multiple DWL-1800R units creating a point-to-multi-point network. How many DWL-1800R units can one DWL-1800B support?
The maximum number of associations is 128. What is the practical limit to the number of DWL-1800R units per DWL-1800B? And, what performance can I expect for a multi-point link?
This depends upon average throughput expectations. All clients would have the maximum throughput available for burst traffic, however the overall average would depend on the utilization of the network. For example, in a heavily utilized network needing about 350Kbps to 500kbps average net throughput per site, 9 to 12 DWL-1800Râ€™s would be the limit. For a moderately utilized network needing about 175Kbps to 258Kbps average, 18 to 24 DWL- 1800Râ€™s should be used, and for a lightly used network needing 32Kbps to 48Kbps average net throughput per site could use up to 128 DWL-1800Râ€™s. What is the range of the DWL-1800B/ DWL-1800R Bridges?
15 miles/24Km (FCC) or 10 KM (ETSI) can be achieved using the UNI-24 antenna kit for a point-to-point link. Consult the antenna and accessory guide range tables for distances using other antennas. Does the DWL-1800B supports 802.1d spanning tree protocol? No, the DWL-1800B/DWL-1800R does not support spanning tree.
What is the normal PER (Packet Error Rate) for the DWL-1800B/DWL-1800R?
The error rate will be about 4%-6% (transmitted fragments vs. retry count). This is typical when operating in a non-interference environment at maximum range for bi-directional traffic loads. If the traffic load is more uni-directional, then the PER will be less. What is the best value for the CW min parameter on the DWL-1800?
Setting the CW min parameter to 31 for heavy bi-directional traffic loads will minimize the PER. Setting the CW min to 15 will improve performance for more uni-directional traffic loads. CW min 7 should only be used for short-range point-to-point links, and 63 should be used for large, long-range multi-point links. Is the D-Link AirPremier DWL-1800 compatible with other D-Link wireless equipment from other vendors?
Yes. However, for the outdoor bridges, interoperability can vary from vendor to vendor and in some cases it may not operate if the manufacturerâ€™s implementation is not pure 802.11b. The DWL-1800B/DWL-1800R can operate at 1, 2Mbps 5.5Mbps and 11Mbps with D-Link Air and Air Plus wireless family products. D-Link Air Premier DWL-1800 units are fully WI-FI compliant. How many DWL-1800B or DWL-1800R units can be collocated on the same building or tower?
You can collocate up to 3 DWL-1800B or DWL-1800R units on the same structure. Each unit is assigned to one of the non-overlapping channels, 1, 6, or 11. Can a Frequency Hopping network operate in the same area as the D-Link Air Premier DWL-1800?
Yes, but in a collocated network both products will suffer some a decrease in performance. The degree of performance loss depends on network utilization. For example, the higher the utilization of the Frequency Hopping network, the higher the level of impact on the Direct Sequence (DWL- 1800) network, and vice versa. Typically, in light to moderately utilized networks, the performance loss is not significant. Can I use D-Link Air Premier DWL-1800 Bridges to feed a Frequency Hopping distribution point? Yes, bandwidth sharing between the Direct Sequence and Frequency Hopping products can be minimized if the network is designed using cross-polarized directional antennas with as much spatial separation as possible. Contact technical support for more information. Performance What is the throughput of the D-Link Air Premier DWL-1800? The DWL-1800B/DWL-1800R bridge link typical performance is 4.2Mbps using TCP and 6.2Mbps using UDP. For long-range links, the performance drops by about 5%. What if the D-Link Air Premier DWL-1800 link experiences interference? If interference is affecting the DWL-1800 link, one of the other channels may be selected to operate away from the frequency of the interference. Also, physically re-locating the antennas may help. What is the typical latency of a DWL-1800B/DWL-1800R?
A point-to-point link would realize about 3mS latency. Firmware Can the DWL-1800B/ DWL-1800R firmware be upgraded?
Yes, the firmware in the DWL-1800B/DWL-1800R is stored in flash and is upgraded using the built in Configuration Utility or the TFTP server. Can the DWL-1800B/DWL-1800R flash be erased or the firmware changed by an unauthorized person?
No, the TFTP server in the DWL-1800B/DWL-1800R requires the SNMP write community name (password) to perform an upgrade. Can the firmware flash be corrupted when upgrading to a new version?
Yes, if the TFTP file transfer is interrupted during a flash update the firmware may be corrupted. The D-Link Air Premier DWL-1800 has a backup flash, which contains the previous version for firmware. If the primary flash is corrupt, then the backup is automatically used to return the unit to an operating state. When does the back up flash image get upgraded?
After completing a firmware upgrade, the backup flash containing the old firmware version is overwritten with the new version on the new power on cycle. Can D-Link Air Premier DWL-1800 firmware be downgraded?
Yes, an earlier version of firmware can overwrite a newer version. Can the previous version of firmware be kept?
The previous version of firmware cannot be kept on the DWL-1800 itself, but can be stored on your PC and loaded if needed. Configuration Can the regulatory domain (country) of a DWL-1800 unit be changed?
No. The regulatory domain is factory set. How can the DWL-1800 be configured or managed if the SNMP Community name has been forgotten?
Press the reset button on the top panel with a paper clip. This will set the read and write Community names to public and private, respectively. How can the DWL-1800 unit be returned to factory default settings?
There are two ways. One way is to use the Default button on the Station Control Tab in the DWL-1800 Configuration Utility. The other is to press and hold the reset button on the back of the unit while powering on the unit. Remember that all settings including IP addresses will be lost when setting defaults.
Management What management options are available for the DWL-1800?
The DWL-1800B/DWL-1800R comes with a graphical Configuration Utility that operates on any Windows based network ready PC. With this utility you can configure and monitor every DWL-1800 on your network. You can also use the DWL-1800 SNMP MIB on standard management platforms like SNMPc, and HP Openview. Does the DWL-1800 offer out-of-band management?
No, the DWL-1800 does not offer out-of-band management, such as a serial port. The DWL- 1800 is managed in-band only via the DWL-1800 Configuration Utility or SNMP. What installation and site survey tools are available for DWL-1800/DWL-1800?
The DWL-1800 comes with a Windows based manager utility. With this utility you can configure link parameters and monitor signal quality and RSSI (received signal strength indication). Optimizing antenna alignment is done using the signal quality and RSSI display. Any computer on the network can use this utility to manage the DWL-1800B/DWL-1800R.
