GB-X10 Installation Guide

1 Introduction

1.1 Purpose

The information in this guide is directed to persons who must perform or coordinate the tasks

associated with the process of installing wireless communication devices and planning

communication network applications.

Installation of a 1+0 non-protected GB-X10 system is described in sections 2 -5.

Installation of 1+1 Hot Standby Protection (Protection) and 2+0 Orthogonal Mode Transducer

(OMT-80) GB-X10 systems are described in section 5. The appendices provide additional

information for GB-X10 systems with any of these options.

1.2 Prior Knowledge

This guide assumes the operator has at least basic experience with, and an understanding of, wireless

technology; and some familiarity with configuring and operating networking equipment. Preferably,

the person installing this equipment fully understands the information covered in this guide, prior to

attempting these procedures.

DANGER, WARNING, and NOTE statements have been placed in various sections throughout

this document to alert personnel of possible traffic-affecting issues, and to provide additional tips

and helpful information. These statements should be closely observed.

GB-X10 Installation Guide

2 Site Planning

2.1 General

Before the start of any installation, a survey of the planned deployment site should be conducted.

The surveying personnel should be fully familiar with the details and requirements needed to

successfully install the GB-X10 radio system.

2.2 Equipment Checklist

The following lists suggested equipment the site survey team may require:

•Binoculars (not always required)

•WAAS-capable GPS location device

•Tape measure to determine distances for cable runs to ingress points

•Digital camera (not always required)

•Site survey report form to document and help assess site

•Signaling mirror (not always required)

2.3 Line of Sight

The GB-X10 80GHz Wireless Gigabit Ethernet link requires Line of Sight (LOS) for proper

operation. Binoculars and spotting mirrors may be used to assist in the confirmation of LOS.

Path planning should include an investigation into future building plans that could block the LOS

path and other long-term incremental obstructions, such as tree growth. Intermittent obstructions,

such as aircraft at a neaGB-X10y airport, should also be considered.

The following table lists near-field distances.

Table 2.3-1: Near-Field Distances

Frequency/Antenna Low Band High Band

80 GHz 1 ft. (30 cm) 17.84 ft. (5.43 m) 20.30 ft. (6.18 m)

80 GHz 2 ft. (60 cm) 71.36 ft. (21.75 m) 81.20 ft. (24.75 m)

The following table details the minimum F1 (First Fresnel) clearance required from obstacles in

order to ensure the radios will operate properly.

2.4 Link Distance

Measurement of the link distance is important in estimating the link availability and calculating the

expected Receive Signal Level (RSSI). This measurement can be performed using the latitude and

longitude coordinate readings from a Global Positioning System (GPS) device, which is placed near

the proposed locations of the antennas. Additionally, a GPS reading will be required in order to

comply with the FCC registration process.

The minimum link distance is dependent on the antenna sizes used along with the minimum allowed

transmit power of 2dBm, so as not to exceed the maximum received signal level of -26 dBm.

GB-X10 Installation Guide

2.5 Antenna Location

The optimum location for the antennas must be determined. The ideal location should provide for

ease of erecting and mounting the antenna, as well as providing unimpeded LOS to the remote

location. The following factors should be taken into account:

•Type of mounting—fixed or roof-safe pole mounting.

•Location of fiber and DC power wiring at ingress/egress of the building.

•Length of cable runs.

•Confirmed earth grounding connection points.

•Obstructions, including allowances for tree growth.

•Accessibility of the radio mounting location.

•Accessibility of the site during and after working hours.

•Monopole towers are not typically stable enough for this application and should be avoided

There is a finite incline and decline range of the elevation

adjustment when installing the radio link.

Depending upon which Manufactures Antenna is used, the mount

can only be adjusted either +/- (25, 30, or 45) degrees from the

mechanical elevation adjustment

2.6 GB-X10 Cover Removal

When the DC, RJ45, or SFP connections are required to be attached to the GB-X10 product, the

Cover will need to be removed and re-installed when connections are completed.

2.8 SFP Modules Installation

The Small Form-factor Pluggable (SFP) is a compact, hot-pluggable transceiver designed to support

Gigabit Ethernet in the GB-X10 product. It is a popular industry format.

This product may only be operated with the SFP types provided by Solectek.

2.9 Cabling Considerations

2.9.1 Fiber and Power

The installation site should be inspected to determine the run paths for the fiber cable and power

cable from the radio equipment to the termination point. Locations for roof penetration should be

identified. The routing and securing of all cables should conform to all applicable codes and

requirements. Depending on the likelihood of damage due to foot traffic or equipment movement,

cabling conduit may be required. The maximum cable run length, as specified for the equipment

being installed, must not be exceeded: refer to Table 2.10-1 for cable types and limitations.

The radio requires LC type connectors on multi-mode and single-mode fibers to properly connect

between the radio and the user’s network equipment. The network equipment end of the fibers

should be terminated with connectors that match the user’s network equipment fiber interface.

9/125 μm SMF

When planning the DC power cable run from the DC power source to the radio unit, it is required to

use 12 or 14 gauge (AWG) cable to ensure adequate voltage at the radio.

12AWG wire is rated up to 9 amps while the 14AWG wire is rated

up to 6 amps which will adequately support GB-X10.

The indoor and outdoor portions of the DC power cabling must conform to all respective indoor and

outdoor national and local electrical and building codes. Requirements may differ for the indoor and

outdoor portions of the cabling, and a grounded surge protector is normally required at the point

where the cable enters the building. The DC power cabling must consist of two 12 or 14 gauge,

stranded conductors, based on your required cable run length.

The maximum cable length is dependent on the power consumption of the radio. The GB-X10 has a

DC input voltage range of ±37.5 to ±60 VDC.
