Figure 2-4-8 Step 4: Configuring Remote Client Bridge Wireless Settings 2.4.2 Mounting the Unit This section describes how to mount the NEXUS and position the antenna. It contains the following sections: • Choosing a Mounting Location and Site Survey • Assembling the Mounting Hardware • Mounting the NEXUS Choosing a Mounting Location and Site Survey Every RF application is a unique installation. Before installing, you should perform a site survey to determine the optimum use of wireless networking components and to maximize range, coverage, and network performance. Choosing a good mounting location for the NEXUS is important because it affects the reliability of the wireless link and maximum data rates it can support. The most important considerations are link length and clearance from obstacles. The following operating and environmental conditions should be taken into account when performing a site survey: • Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio range is achieved at the lowest workable data rate. A decrease in receiver sensitivity occurs as the radio data increases.
FCC ID PWG NEXUS 1 10 Installation Manual • Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio range. As a general rule, antenna height helps to reach longer distances to avoid obstruction. However, do not place the antenna higher than necessary, because the extra height also increases potential interference from other unlicensed radio systems. Do not install the airHaul Nexus on a TV or Radio receiving mast or within proximity of the same. • Physical environment—Clear or open areas provide better radio range than closed or filled areas. • Obstructions—Physical obstructions such as buildings, trees, or hills can hinder performance of wireless devices. Avoid locating the devices in a location where there is an obstruction between the sending and receiving antennas. Link Distance In an environment without obstacles in the signal path, the maximum link distance depends primarily on the type of antennas and the free space path loss. Make sure your proposed mounting site is within range of the remote antenna. The NEXUS units have a built-in Link Analysis Calculator to help you estimate the range for your specific installation. Antenna Polarization The antennas radiate and receive polarized radio signals. Polarization helps reduce interference because the antenna tends to reject cross-polarized signals from other sources. Therefore, you can solve some interference problems by changing the antenna polarization. For the link to operate correctly, two antennas at each end of the link must always be set for the same polarization, either vertical or horizontal. The NEXUS mounting hardware accommodates either vertical or horizontal antenna polarization. Signal Path Clearance (Fresnel Zone) A radio beam travels from one antenna to another in a straight line. Therefore, the path between the antennas must be free of major obstacles. The effects of obstacles and terrain, both along and near the path, have a significant bearing on the propagation of radio signals and can cause both interference and signal cancellation. When choosing a site, consider the effects of the following common obstacles: • Trees and large plants - A tree directly in the path can totally block the signal. With clearance above the trees there are usually no secondary effects, but you should allow for future tree growth. • Man-made obstacles - A large round container such as a gas storage reservoir or water tower that is partially in the path causes some blocking. These obstacles may also reflect some energy, which can interfere with other receivers. Square or rectangular objects in or near the path have rectangular surfaces that can block and diffract signals over and around them. • Earth surface - The earth surface also interferes with signals if the antenna is mounted too low. Mount the antenna just high enough to allow adequate clearance from the ground. Placing the antennas too high makes it susceptible to interference from other systems.
FCC ID PWG NEXUS 1 11 Installation Manual For tower installations, you may need to climb the tower to verify a clear path to the other site. If trees are in the line of signal propagation, leave extra clearance above them for future growth into the signal path. Table 5-1 (below) can be used as a guide to determine the clearance to leave around the signal path. Install the bridge or external antenna where obstacles along the propagation path, including the ground, are no closer than these values. Total Path Length Km (Miles) Clearance Radius Around Signal Path Meters (Feet) 2.4 GHz Clearance Radius Around Signal Path Meters (Feet) 4.9 GHz to 5.8 GHz 6 (4) 8.4 (27.6) 5.4 (17.9) 10 (6) 10.3 (33.8) 6.7 (22.0) 13 (8) 11.9 (39.1) 7.7 (25.4) 16 (10) 13.3 (43.7) 8.6 (28.4) 20 (12) 14.5 (47.9) 9.4 (31.1) Table 5-1 Fresnel Zone Clearance Guidelines for Frequencies How to Mount the NEXUS This section describes the mounting procedures for rooftop, mast, and tower installations.

To mount the NEXUS on a pole, follow these steps: Step 1 Attach the NEXUS unit to the square plate on the mounting bracket with the supplied bolts. Step 2 Find a suitable mounting location on the tower or wall. (If required, drill holes on the wall corresponding to the mounting bracket holes.) Step 3 Hoist the entire assembly to the mounting location. Step 4 Attach the mounting arm assembly to the wall or to the tower pole using the supplied U bolts, which fit 1.25 to 1.75 inch poles. Step 5 Loosen the screws and adjust the vertical and horizontal alignment one at a time to point towards the remote NEXUS unit. Note Factory assembled smartBridges antennas are vertically polarized. Be sure to mount the unit so that the antenna polarization matches the remote antenna polarization. If it does not, remove the four bolts, rotate the parabolic dish 90 degrees and reattach. 2.4.3 Wireless LAN installation guide lines and Authorization for use Installation and use of this Wireless LAN device must be in strict accordance with the instructions included in the user documentation provided with the product.
