Airaya – Fast and affordable outdoor wireless bridges System Requirements Before installing the AI108-4958-N, AI108-4958-SU, AI108-4958-1, or AI108-4958-Kit, be sure you have the following items on-hand: An AC power outlet (100 to 120 V, 50 to 60 Hz) or (optional 100220 V, 50 to 60 Hz) to supply power to each indoor bridge unit An outdoor antenna mast with a 1 to 6 inch (25.4 to 152.
Airaya – Fast and affordable outdoor wireless bridges Hardware Installation Indoor Bridge Connections Figure 5. Front and rear panel views The AI108-4958-N, AI108-4958-1, or AI108-SU connect to your network with a standard 100/10 Mbps Ethernet cable; and connects to the outdoor antenna using an RF cable. The AI108-4958-N, -1, -SU units features the following LED status indicators: LED Indication Power LED Blinks while bridge is powering up and performing power-on self-test.
Airaya – Fast and affordable outdoor wireless bridges Before you mount the AI108-4958-N, AI108-4958-1, or AI108-SU to a fixed location, consider the following requirements to determine the optimal placement: The RF cable between the AI108-4958-N, AI108-4958-1, or AI108-SU and the antenna should be as short as possible without putting too much stress on the connectors at the bridge and antenna. The RF cable attenuates (reduces) the radio signal and will reduce the effective range of your wireless link.
Airaya – Fast and affordable outdoor wireless bridges Installing and Visually Aligning Outdoor Antenna To ensure maximum performance and stability of your wireless link, it is crucial that you determine the right locations for the outdoor antennas based on the following criteria: • A good signal path, ideally with visual line of sight and adequate Fresnel clearance between bridges • Minimal distance between bridges • Minimal reflections from other objects. Figure 6.
Airaya – Fast and affordable outdoor wireless bridges Follow these steps to install and visually align outdoor antennas: 1. Attach the antenna to a mast or side of a building using the included bracket. 2. Align the outdoor antenna horizontally: Loosen the horizontal adjustment bolt and nut to visually aim the antenna at the remote bridge. Set the appropriate horizontal angle and tighten the horizontal adjustment bolt and nut so that the angle is locked in place. 3.

Airaya – Fast and affordable outdoor wireless bridges Antenna alignment and link monitoring tool Each WirelessGRID bridge includes an integrated signal strength monitoring tool for use during setup and bridge operation. Use this tool to optimize antenna alignment during initial link setup. You can also use this tool to remotely check or continuously monitor the signal strength between any two bridges in a WirelessGRID network.
Airaya – Fast and affordable outdoor wireless bridges Using the real-time signal strength monitor for antenna alignment It is a good idea for you to become familiar with the product before installing it for the first time. AIRAYA recommends you perform a bench test before deploying any units to the field. The bench test and verification process can also be performed in the field, but it is generally much easier to configure the units on the bench before setting them up in the field.
Airaya – Fast and affordable outdoor wireless bridges indicate the RSSi (signal strength) of the RF packets sent from the remote bridge. TIP If you do not see values streaming across the screen, confirm that both bridges are powered on and then manually aim the bridges at each other until the values appear. If you see very few or no values streaming across the screen, there is probably no traffic going across the radio link.
Airaya – Fast and affordable outdoor wireless bridges Antenna Adjustment Using the real-time Signal Strength Monitor In the initial hardware installation, you visually aimed the antennas at each other. Though a good first step, this does not provide optimum antenna alignment, signal quality, or maximum throughput. To fine-tune your antennas, we recommend that you perform the following procedures at both ends of a link: 1. Start the Signal Strength Monitor on one end of a link. (We’ll call this Side A.

Airaya – Fast and affordable outdoor wireless bridges Appendix A – Bench Test Procedure This WirelessGRID bench test guide is designed to provide a new AIRAYA installer with insight and understanding of how to setup, test and verify the functionality of a WirelessGRID link before performing a field installation. Utilities for testing network communication, configuring bridges, aligning antennas, and measuring throughput are discussed.
Airaya – Fast and affordable outdoor wireless bridges If you receive ping responses from both test stations, the network IP configuration and physical wiring is working properly between the 2 test stations using Ethernet. If you cannot ping both test stations, check your Ethernet cable connections and test station network settings to verify they are configured properly. NOTE If ping does not work between 2 wired test stations, it will not work between 2 test stations connected by a WirelessGRID link.
Airaya – Fast and affordable outdoor wireless bridges 1. Start a continuous ping from test Station A to bridge end point A. To start a continuous ping using the factory default IP settings of the bridge, type the following into a DOS or CMD window on test station A: Ping 192.168.1.70 –t (leave this ping window running so you can see ping results easily) 2. If there is no response, try IP address 192.168.1.71, or cycle the power on bridge end point A.
Airaya – Fast and affordable outdoor wireless bridges Step 3. Setup bridge software configuration for bridge After verifying that both bridges and their respective test stations can communicate via Ethernet, you will need to setup and verify bridge configuration so they will be able to communicate over the radio link. The configuration given here will be a minimal configuration for test purposes; for more detailed configuration information, please refer to the product manual.
Airaya – Fast and affordable outdoor wireless bridges Step 4. Test network connectivity across a WirelessGRID link After verifying that both bridges and their respective test stations can communicate via Ethernet, and confirming new WirelessGRID bridge list entries were saved, the following ping tests should be done. NOTE After rebooting bridges, the radio link should be established within one minute. If TPC and DFS are enabled, this process may take up to two minutes.
Airaya – Fast and affordable outdoor wireless bridges You may have an http configuration error - Verify the configurations of both bridges using the http NMS. Bridge A should have an entry in its WirelessGRID Bridge List for the MAC address of the bridge B, and bridge B should have an entry in its WirelessGRID Bridge List for the MAC address of the bridge A - without correct MAC addresses (bridge authorization) in each side of the link, the bridges will not communicate or let traffic pass.
Airaya – Fast and affordable outdoor wireless bridges Step 5. Running the real-time Signal Strength Monitor In this document, we discuss only the use of the WirelessGRID’s exclusive real-time signal strength monitor. At anytime and from any location in your network, this monitoring tool can be used to check signal quality between any two WirelessGRID bridges in the network.
Airaya – Fast and affordable outdoor wireless bridges NOTE If you see very few or no values streaming across the screen, there is probably no traffic going across the radio link. You can generate traffic by opening additional ping windows or FTP file transfers on your test stations if you do not have a trafficgenerating program. The first 20 values displayed on each line represent individual RSSi values; the 21st represents the average of the first 20 values (e.g.: avg: 19).
