5 Pre-installation 5.1 I ntroduction Before you begin installing your LibraPlus radios, you need to take certain issues and conditions into consideration, prior to, and throughout, the entire installation process. This chapter defines some of the more common installation concerns.
• hole saw Specialized Tools • Crimp tools for: • Ethernet connectors • RF connectors • power and grounding compression lugs • Laptop or PDA Test Equipment • spectrum analyzer to check for interference • site master to check the antennas for proper VSWR Consumables • butyl rubber tape or pads • anti-oxidizing paste • low temperature tape Miscellaneous • ladders • compass • GPS • binoculars Cables • DB9 serial cable (male to female) for the base station • EI ON proprietary se
You should review the proposed cabling entrance/ exit points for the site’s building; they must be practical. You must be able to easily drill the holes for cable access and the cables should be in a location that allows for easy maintenance. The LibraPlus has a single shielded CAT5/ 5e cable to connect the LibraPlus 5860 to the power inserter. I t is important not to exceed the maximum allowed length of 100 meters for this cable. This Ethernet cable provides power to the AP. 5.3.
• Keep any non-conductive material, such as Styrofoam and other plastics, away from your work area 5.4.2 LibraPlus Unit Grounding When you are installing your outdoor units, you need to follow proper grounding practices. The proper grounding of outdoor units helps to minimize lightning damage and dissipate static buildup.
Figure 5:1 Daisy Chain Configuration Daisy chaining the grounds of your units will cause problems such as ground loops, high resistance paths between units, and reduced ability for dealing with lightning. I nstead, you should use a star conf iguration, as shown in Figure 5:2 Star Conf iguration. I n this conf iguration, each outdoor unit’s grounding lug is connected to a common grounding point that is then connected to the earth ground. Figure 5:2 Star Configuration 5.4.
Figure 5:3 Surge Suppressor Sides 5.4.4 Surge Suppression Unit Location Lightning arrestors and surge protectors should be installed at all input/ output points on the LibraPlus equipment. Additionally, they should be properly grounded by connecting the body of the arrestor or protector to the grounding system with a heavy gauge (6 AWG) copper wire. This grounding wire should be as short as possible.
Figure 5:4 LibraPlus Surge Protector Diagram w ith I ntegrated Antenna ( RD) LibraPlus 5860 User Guide Pre-installation: Grounding Page 25 of 95
Figure 5:5 LibraPlus 5860 Surge Protector Diagram w ith External Antenna ( ER) When installing surge suppressors between your LibraPlus unit and the antenna, use protectors that provide a DC short such as an L-C circuit or one quarter-wave shorting stub. These protectors should be physically located as close as possible to the ODU, preferably no further than f ive (5) feet (1.52 metres). Also, a star conf iguration should be used when grounding your surge suppressors. 5.
• Scotch® 130C Linerless Rubber Splicing Tape • Scotch® Super 88 Premium Vinyl Electrical Tape Corrosion is another problem that arises if your cabling system is not properly weatherproofed. Corrosion can lead to high impedance at contact points, which can drastically reduce the effectiveness of your lightning protection. To help stop corrosion, you should use an anti-oxidizing paste on all contacts.
6 LibraPlus I nstallation This chapter discusses how to install your LibraPlus equipment. There are four general tasks that you will need to perform when you install your LibraPlus. They are: 1. Conf iguring your LibraPlus 2. I nstalling your LibraPlus 3. Mounting the antenna, if the equipment uses a separate antenna 4. Cabling the LibraPlus Please review the Pre-installation chapter before you begin installing your LibraPlus equipment. 6.
Figure 6:1 Mounting Bracket Unit Anchor Figure 6:2 Attaching the Mounting Bracket Unit Anchor 6.4 I ntegrated Antenna Mounting I f you are mounting your LibraPlus and the unit has an integrated antenna, you will have to consider the antenna’s polarization. When you later install the unit on the pole or wall, you will need to install it so that the antenna’s polarization arrow is pointing as shown in the examples below.

Before you begin, review the material in the Preinstallation chapter of this manual and make certain that you have met all of the conditions laid out there. Also, you should make certain that all of the necessary brackets and bolts are included in the box with your unit. To mount your LibraPlus unit on a pole: 1.
Figure 6:5 Attaching the Bracket to the Pole 1.2. Tighten the bolts so that the bracket will not move. The recommended maximum torque is 24 N/ m (17.7 ft/ lbs). I f your LibraPlus has an integrated antenna, as shown in the f igure below, do not tighten the mounting clamp bolts unit you have aligned your antenna. 1.3. Bolt the mounting bracket’s unit anchor to the unit’s housing, as shown in the f igure below. Tighten the bolts so that they are snug.
Figure 6:7 Securing the radio to the pole 1.5. Tighten the pivot nut and bolt. The recommended maximum torque is 24 N/ m (17.7 ft/ lbs). I f your LibraPlus radio has an integrated antenna, do not tighten the pivot nut and bolt until you have aligned your antenna. 6.6 Wall-mounting the LibraPlus Radio 1. To mount your LibraPlus radio to a wall: 1.1. Prepare the wall to hold the mounting bracket. The type of mount you create will depend upon the type of wall surface and material your wall is made of.
1.4. Bolt the bracket’s unit anchor to the housing, as shown below. Figure 6:9 Attaching the Bracket to the radio 1.5. Tighten the bolts so that they are snug. Do not over tighten the bolts, as they could crack the housing. The recommended maximum torque is 5.7 N/ m (4.2 ft/ lbs). 1.6. Connect the radio to the mounted wall-side bracket, using the pivot arm, as shown below. I f your LibraPlus radio has an integrated antenna, do not tighten the pivot nuts and bolts unit you have aligned your antenna.
6.7 Antenna Mounting Guidelines I f your LibraPlus does not have an integrated antenna, it is essential that you properly install an external antenna. This ensures that your system is operating at optimum performance and aids in protecting it against lightning damage. To correctly install your antenna, it is very important that you follow your antenna manufacturer's installation instructions closely. I n addition, keep the following guidelines and practices in mind while performing your installation. 6.7.
Figure 6:12 Complete Cabling Diagram 6.9 Cabling up to the LibraPlus Radio Cabling from your indoor terminal equipment (PoE) to your radio is straightforward. To cable your LibraPlus radio: • Mount the radio’s power inserter on the wall, close to the cable’s exit point from the building. How you mount the power inserter will depend upon certain issues, such as the type of wall surface and material your wall is made of.

11 Appendix B: Definitions 11.1 A Absorption Antennas mounted too close to “soft” objects, such as trees, may experience a reduction in signal strength due to absorption. Absorption is most often encountered in antennas installed during fall or winter. The problem does not start until the spring, when leaves appear. Access Hub A group of APs, each serving a group of CPEs. Also called a cellsite. Access Point The base station of the network.
11.2 B Bandwidth The size of a communications channel, measured in cycles per second. "Bandwidth" is often used as a synonym for data rate. Base Station The central control unit of the wireless network. A base station polls remote units and routes traffic to them. The base usually connects to a major access point of main network. Beamwidth The beamwidth of an antenna describes how a signal spreads out from the antenna, as well as the range of the reception area.
CrossPolarization Discrimination This specifies the signal isolation achieved when the receiving element of an antenna is perpendicular to the radiating element. This is important when co-locating Access Points. 11.4 D dB Decibel. A relative measure used to specify power gains and losses. The difference between power P1 and power P2 expressed in dB is: 10log10(P1/ P2) DB-9 A D-shaped connector to the serial port on EI ON equipment, with nine pins. Used to connect the I DU and PC.
11.5 E EEPROM Electrically Erasable, Programmable Read Only Memory: Nonvolatile memory, it must be removed from board to be erased. EIRP Effective I sotropically Radiated Power. EI RP is the amount of power transmitted to the air by the antenna. EI RP levels depend on the power of the radio transmitter, the type of antenna, and the losses incurred in the antenna cable. ERP Effective Radiated Power.
11.7 G Gain The ability of a device to amplify a signal. Gain is the ratio of output power divided by input power, usually expressed in decibels (dB). Gain can also be measured as an absolute value, referenced to an input signal of one milliwatt (dBm). For antennas, gain measures the ability of an antenna to focus a signal and is expressed in dBd (half-wave dipole reference) or dBi (isotropic radiator reference). GPS Global Positioning System.
LOS Line of Sight (Free Space) An unobstructed straight line between two transmitting devices. The transmission path is not established by nor dependent upon reflection, refraction or diffraction. As long as 60 per cent of the first Fresnel zone is clear, then it may be considered almost equivalent to LOS transmission. Link budget The amount of power, expressed in decibels, needed for a radio link to work. Linktest A method of proving a new radio link or troubleshooting an existing one.
Null An RF signal component with a smaller amplitude than the rest of the RF signal in multipath interference. Nulls are caused by subtractive combination as a result of multipath fading. Null Depth The ratio in dB between the strongest OFDM carrier and the weakest carrier in multipath interference. A null depth of zero indicates that there is no multipath reception. 11.
Ping A method of testing a link. Executing the ping command sends a signal to the remote station. The station returns the signal. I f the signal comes back on time and intact, the link works. See Also FTP. Polarization The orientation of the radiating element of an antenna with respect to Earth. The polarization of antennas is usually described as vertical, horizontal, or circular. PN Pseudo-random noise. A code used to change a narrowband signal into a spread spectrum signal.
RF Station I D This is a configurable number, from one to 2.048, that identifies an AP or CPE to the network. RSSI Received Signal Strength I ndicator. Strength of received signal expressed in dB. The Access Point measures RSSI as a fade margin value. 11.16 S Sensitivity The minimum signal strength required for usable performance, expressed in dBm.
11.18 U Uptilt See Also Dow ntilt . 11.19 V VSWR (Voltage Standing Wave Ratio) VT 100 VSWR is the voltage ratio of minimum to maximum across a transmission line. A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a VSWR of 1.5:1. For example, when using a radio with a four-watt output with an antenna VSWR of 1.5:1, the reflected power will be 160 milliwatts. A terminal emulation system. 11.20 W WAN Wide Area Network.
