Site Identification – General Requirements
• Tall structure such as radio towers, buildings, and water towers are ideal radio sites
• Source of power is needed– AC, DC, Solar
• Data source must be available– IPOP (Internet Point of Presence)– T1/E1, Satellite, fiber, backhaul, etc.
• Is the frequency you plan to use available?

Submission
Site Identification – Visual Validation
• How high does the radio need to be mounted?
• Are any major obstructions between the tower radios and potential “remote” installations?
• What is the roof material made out of? – Many owners of membrane roofs will not
allow you to access the roof when the temperature is below 320.

Submission
Site Identification – Physical Protection
• Is the site properly grounded?• Is there lightning protection?• Is there a radio shed for equipment that
cannot survive outdoor conditions?• Can you access the site after hours to
perform maintenance?• Can the tower physically support the
equipment AND a climber?

RF Analysis - Conduct Potential Site Assessments
• Begin identifying locations for the radios– Study local and topographical maps– Drive the proposed coverage area– Take photographs
• If necessary, use a Spectrum Analyzer to sweep the proposed coverage area to determine what type of RF activity is present. – Canopy Subscriber Modules and Backhaul
Slave modules (10 or 20 Mbps) can be used as spectrum analyzers.
– The Canopy 45 Mbps backhaul has a Link Calculator tool that should be used when assessing potential paths.

RF Analysis - Graphical Spectrum Analyzer Display
• Enable the Spectrum Analyzer from the SM or BHS Expanded Stats web page.
• All frequencies in the band are scanned and reported.
- Green bars show the latest reading.
- Yellow tick marks show the maximum reading over time.
- Red tick marks indicate strong readings (-40 dBm or greater).
• Select Enable to refresh the readings, or set the page to auto-refresh.
• Select Disable to re-establish SM or BHS connectivity to APs or BHMs.
• Enabling Spectrum Analyzer will drop the RF link. If not disabled, the Spectrum Analyzer will time out after 15 minutes.

Installation – LPS/Grounding
• Outdoor Considerations– Masts, Towers– Transmission lines– Outdoor enclosures– All cable entering or leaving a structure– Radios
• Canopy radios must NOT be mounted directly to lightning rods
• Radios should be 2’ or more below the top of mounting structure.
• Properly designed Lightning Protection Systems (LPS) should provide a path for current to travel to ground.

Installation - LPS Components
• Air Terminals – Slender rods installed on roof or tower as defined by industry standard.
• Conductor – Copper cabling that interconnect the air terminals and grounding plates.
• Ground Terminators – Metal rods driven into the earth to guide lightning current harmlessly to ground.
• Surge Arrestors and Suppressors – Devices installed in conjunction with a LPS to protect electrical wiring and electronic systems. Should be installed at point of entrance of cable into a building.

Installation - Tools
• Safety Harness must be worn at all times when climbing.
• A multipoint safety harness can be purchased for approximately $270.
• Tower Climbing Safety & Rescue (book by Comtrain) $29.95. Contains ANSI, OSHA, and CSA climbing and tower requirements.

Installation – Basic Tools
• Punch down tool - $69.00
• Cat5 Cable tester - $79.00
• Cat5 Cable crimper - $45.00
• Fluke 110 Volt Meter -$99.00
• Wire cutters, screw drivers, small socket set, tie wraps

Installation – Alignment and Configuration tools
• Laptop or iPAQ – Needed for accessing Canopy web page via the Ethernet (RJ45) interface.
• Audio Tone headset for alignment – RJ11 port on SM and BHS’s produces volume, pitch, and cadence.– Volume – higher volume
means less Jitter– Pitch – higher pitch means
better RSSI– Cadence – tone interruption
of .155 seconds every 2 seconds means the SM/BHS has registered.
