Site Planning Prior to installation, develop a checklist that covers all aspects of the installation. A well-developed plan identifies potential problems early so that they can be solved timely. Choosing a Mounting Location Choosing a good mounting location for the bridge is important because it affects the reliability of the wireless link and maximum data rates the bridge system can achieve. The most important considerations are distance between bridges and clearance from obstacles.
The Fresnel Zone is important to the wireless link as it defines an area around the LoS that can introduce RF signal interference if blocked. Objects in the Fresnel Zone such as trees and buildings can diffract or reflect the main signal away from the receiver, changing the RF LoS. Antenna Polarization The integrated antenna radiates and receives polarized radio signals.
Chapter 3 Hardware Installation The DAP-3760 / DAP-3860 Wireless Bridge is shipped with mounting hardware that accommodates tower or mast installations. This chapter demonstrates the hardware installation procedures, which include Assemble the Hardware Mounting, Pole Mounting, Connect Up, Ground the Wire, Power On and Align the Antennas. Assemble the Mounting Bracket 1.
Pole Mounting 1. Install the main bracket and the pole mount bar over the top of the pole by securing the drill holes of the pole mount bar to the main bracket ones and insert two M8×110 screws, spring washers and washers through the drill holes and main bracket; 2. Fasten two M8×110 screws and washers through the drill holes and main bracket with a spanner; 3. Adjust the antenna for appropriate tilt / vertical orientation.
Interface Definition DAP-3760 / DAP-3860 currently provides two interfaces at the bottom, which are PoE & Data with a black plastic dummy cover and RS-232 with a white dummy cover. Among which, a black RJ45 waterproof connector will be provided for the PoE & Data interface. RS-232 RS-232 is used for debugging purposes as well as for hard reset of the DAP-3760 / DAP-3860. Below you may find the pin definition of the RS-232.
To reset the device, short P7 (Hard Reset) to P8 (GND) for less than 1 second and the system will reset. If P7 (Hard Reset) is shorted to P8 (GND) for over 5 seconds, the DAP-3760 / DAP-3860 will be reset to the factory default settings.
Connect Up Before installing the Ethernet cable with a waterproof RJ-45 connector, it is recommended that the Cat-5 RJ-45 coaxial cable be used for the DAP-3760 / DAP-3860 to power injector connections. 1. To connect to the hole labeled PoE+Data, open the black cover in advance by using a coin or a slotted screwdriver and then screw in the body of the gland and tighten. Connect Up – Step 1 2. Slide the sealing nut to the RJ-45 cable from its middle breach and then insert the sealing into the cable.
Screw the sealing on the gland and tighten. Connect Up – Step 4 Grounding The DAP-3760 / DAP-3860 is shipped with a grounding wire. The unit must be properly grounded to protect against power surges. The DAP-3760 / DAP-3860 grounding point can be found on the bottom of the unit. It is supplied with an appropriate grounding lug for attachment to the ODU. Ground the Wire. Grounding Power on To power up the DAP-3760 / DAP-3860, follow the steps bellow: 1.
2. Plug a user-supplied Cat-5 Ethernet cable from the DAP-3760 / DAP-3860 into the power injector RJ-45 jack (P+DATA OUT); 3. Connect the power module to the power injector and plug the AC cord into an AC power receptacle; 4. After being powered on, the device will send out the beep sound lasting about 1.5 seconds, informing you that the DAP-3760 / DAP-3860 is powered up! Wait for about 60 seconds the system will be initialized and start working. 1.
Align Antenna After powering up the wireless bridge, align the integrated antenna to point in the approximate direction of the remote bridge antenna. If the antenna is at a significant angle, use binoculars, satellite global positioning system (GPS) or reference objects to detect the remote bridge or antenna, and then manually adjust the horizontal and vertical positions accordingly. To verify whether the two antennas are correctly pointed to each other, ping the remote wireless bridge.
3. After the two integrated antennas are well positioned, secure the bridge mounting fasteners. The bridges now are ready to be configured and incorporated into your network.
Chapter 4 Configuration The units to be installed should be configured before physical installation. During this process, the installer can set the unit’s IP address to the one within desired address range and set each unit up with the MAC address of its peer unit ready to establish a wireless link. It is recommended that this procedure be carried out on the bench before physical installation. This chapter describes how to configure your bridge for the first time.
3. Enter the user name (admin) and password (password) to login and make configurations. 4. After configuring the bridge, remove the Ethernet cable from PC and connect the power injector back to your wired LAN port. Basic Settings After login to the Web-based management interface, you will see the “About” page as below. Click “Basic” in the left menu bar to make basic system configurations.
IP Address Enter the settings obtained from your system administrator. The most important setting is IP Address. You may manually assign an IP address or check “DHCP” to automatically obtain one from DHCP server on your network.
CPE Under this mode, the bridge connects to a remote LAN and that Base Station. Select “Multicli” or “LAN-to-LAN” for your network application and specify the SSID of the corresponding Base Station.
Peer to Peer (CSMA) Under peer-to-peer (CSMA) mode, set the same channel for all the peer units. Open “Peer-to-Peer Links” (as below) page to enter the MAC address of the remote peer unit. Peer to Peer (TDMA) Under peer-to-peer (TDMA) mode, set one group ID for all the peer units.
Base Station ID The SSID is a unique identifier that bridges use to associate to each other. It is case-sensitive and consists of no more than 32 alphanumeric characters. By default, it is set to “Wireless”. Output Power If the bridges are installed less than 328ft (100m) apart, the output power should be adjusted lower to avoid overloading the bridge’s receivers. To configure the output power, open “Radio” and select the appropriate output power value: Full, Half, and Quarter.
Alternatively, under “Base Station” mode, by clicking “Edit”, the “Security Profile Configuration” window will popup. You can set the SSID and security configuration here. Network Authentication Type Open System: It allows any device to join the network without performing security check.
Shared Key: Encryption strength and key are required. WPA-PSK: No need for specific authentication server. In this so-called WPA Pre-Shared Key, all you have to do is just pre-enter a key in each WLAN node and this is the common way to be adopted in large and middle enterprise as well as residential network. WPA2-PSK: Only all the clients support WPA2, can it be available. If it is selected, the data encryption type must be AES and the passphrase is required.
Chapter 5 Troubleshooting This chapter provides troubleshooting procedures for basic problems with the bridge. Q 1. What if my bridge fails to connect to the remote one? • Ethernet Link: Check the availability of power to the bridge by observing the LED status on the power injector. - Green: The wireless bridge is connecting to the backhaul network.
