6LWH (YDOXDWLRQ Chapter 1 describes the process for completing a proper site evaluation. 1.1 What Is a Site Evaluation?......................................... 1-2 1.2 Why Perform a Site Evaluation? ............................... 1-2 1.3 Preparing for a Site Evaluation ................................. 1-2 1.4 Site Evaluation Process ............................................. 1-3 1.5 Documenting a Site Evaluation ...............................
Installation and Commissioning Guide - R2.0 1.1 What Is a Site Evaluation? A site evaluation consists of a series of procedures for gathering specific information about potential IFU locations. These processes are outlined in Section 1.4, Site Evaluation Process. Use these procedures to gather the required information and record that information on the site evaluation form. This information is critical to the successful design and deployment of a network. 1.
Site Evaluation The following tasks must be completed prior to performing a site evaluation: • 1.4 Prepare the initial network design plan by performing the following: ß ß Identify potential buildings by identifying targeted customers Identify potential links by selecting buildings based on the high probability of line of sight • Arrange for access with the facility personnel into the buildings, equipment rooms, and architectural plans to become familiar with the location of all ducts, risers, etc.
Installation and Commissioning Guide - R2.0 1.4.2 Ensure Compliance With Laws, Regulations, Codes, and Agreements Ensure that any installation performed as a result of the site evaluation is in full compliance with applicable federal and local laws, regulations, electrical codes, building codes, fire codes, and licensing agreements. 1.4.
Site Evaluation • A minimum of 0.5 inch (12.7 millimeters) diameter or bolts with lock washers or positive locking nuts are used. • The minimum distance between IFUs is three feet (91 centimeters). Refer to the Triton Network Systems white paper RF Design Guidelines for Consecutive Point Networks for additional information about colocating IFUs. • The bottom of the IFU is a minimum of seven feet above the roof to ensure line of site is maintained.
Installation and Commissioning Guide - R2.0 • Polarity (horizontal or vertical) • Transmit power level • Antenna direction 1.4.7 Measure the Link Distance The two ways to measure link distance are as follows: • GPS - record the latitude and longitude for the near and far IFU sites and calculate the link distance. NOTE: Record the mapping datum used by the GPS unit and ensure the same mapping datum is used for all site evaluations in a given network.
Site Evaluation 1.4.10 Determine Site Equipment Location and Requirements Site equipment can be installed in a free-standing rack or wall-mounted cabinet. Triton Network Systems recommends a lockable cabinet for maximum physical security. A site equipment cabinet typically contains the power source for an IFU and is the primary cable termination point for the power, GPI, and fiber optic cables that are connected to an IFU. It is possible to mount the site equipment indoors or outdoors.
Installation and Commissioning Guide - R2.0 • Use a custom fiber outdoor cable assembly of sufficient length to directly connect the IFU to the site equipment interface. It is the customer’s responsibility to determine the required length for custom cables and to acquire custom cables from a third-party provider. Triton Network Systems Customer Service will assist in determining proper specifications for cables if so requested by the customer.

Installation and Commissioning Guide - R2.0 • UV-rated plenum cable (Option 2). This option uses a single UV-rated plenum fiber cable to connect directly to the site equipment interface without the use of conduit or a demarcation box. Use Option 2 when the site engineering plan specifies that the IFU fiber cable will be installed within building heating, ventilation and air conditioning (HVAC) ducts (see Figure 1-1 B). NOTE: Only plenum-rated cables should be installed within building HVAC ducts.
Site Evaluation 1.4.12 Determine the Length of Power Cables When Using Triton Network Systems Outdoor Power Cables Table 1-1 and Table 1-2 show the maximum lengths of indoor power cable lengths when used with representative Triton Network Systems outdoor power cables. Table 1-1: Maximum Indoor Power Cable Length with One Pair of Conductors Outdoor Cable Length (Feet and Meters) Indoor Cable Gauge 65 Feet (20 Meters) 133 feet (40 Meters) 333 Feet (100 Meters) 10 AWG 1125.6 (343.1) 1090.0 (332.2) 992.
Installation and Commissioning Guide - R2.0 Ro is the resistance of the outdoor cable (see Table 1-4) w is the number of pairs of wires in the indoor cable tCu is the temperature coefficient of copper and is equal to 1.003930 In most cases, a 10, 12, or 14 gauge wire will be used in the indoor cable. Table 1-3 gives R· values for these three wire sizes. Table 1-3: Resistance Per Foot R· 10 AWG 12 AWG 14 AWG .001 Ω/ft. .00202 Ω/ft. .00252 Ω/ft.

Otherwise, use this procedure as a guideline to ensure that the IFU sling has been properly secured to the IFU. 1. If the sling is not already placed over an IFU, carefully remove the sling from its container. 2.

Mounting and Aligning an IFU 10. Neatly fold the sling and store it in a cool, dry, dark place to prevent environmental damage. 4.3.2 Mounting the IFU Use the following procedure and refer to Figure 4-6 to mount an IFU on a mounting bracket: 1. Make sure that the model number of the IFU (located on the aft housing assembly) matches the model number referenced on the site drawing in the site engineering folder. 2.
Installation and Commissioning Guide - R2.0 4.3.3 Attaching IFU Cables 1. Remove the dust caps from the power, GPI (optional), and fiber optic cables. 2. Connect the power, GPI (optional), and fiber optic cables to the IFU locations as shown in Figure 4-7. NOTE: To prevent shearing of the fiber, hold the base of the fiber cable with one hand and secure it on the connector by rotating the twist lock with your other hand. 3.
Mounting and Aligning an IFU 4.4 IFU Alignment The alignment procedure should be performed for one IFU at a time. Do not attempt to align both the near and far IFUs in a link simultaneously. This procedure requires personnel to be present at both the near and far IFU. 4.4.1 Alignment Setup Use the following procedure and refer to Figure 4-8 to set up an IFU for alignment: 1. Loosen the four vertical alignment screws, the horizontal alignment nut, and visually align the near IFU to the far IFU.

Repeat Step 10 through Step 13 for the far IFU. 14. Using IFU link manager, verify modem lock on both IFUs. 15. Using IFU link manager, turn on AdTPC for both the near and the far IFUs. 16. Verify that AdTPC reads Power Control, indicating that power control is on and active.
Mounting and Aligning an IFU 4.5 Link Verification RF link verification is based on meeting the following objectives: • Minimizing RF Tx power for dense deployment • Avoiding “side lobe” link alignment • Achieving rapid deployment by verifying link at the time of installation The RF link verification procedure focuses on the RSSI and modem power display for IFU wireless links.
Installation and Commissioning Guide - R2.0 Verify Main Beam Alignment Use Tx power to determine if you are aligned on a side lobe. First, make sure AdTPC is turned on. Second, record the Tx power on both sides of the link. If (Tx1 - nominal Tx) < 3.5 dB or (Tx2 - nominal Tx) < 3.5 dB, proceed to Verify Link Integrity. Otherwise, realign the link. NOTE: If main beam alignment and modem power are verified, minimum Tx power is being transmitted.
Mounting and Aligning an IFU 4. Move the IFU up and down (using fine motions) until you obtain a peak reading on the voltmeter. 5. Tighten the four vertical alignment screws on the bracket. 6. Tighten the horizontal alignment nut. If two equal peaks appear while sweeping the vertical plane: 1. Move the IFU to the null spot in the middle of the two equal peaks. 2. Tighten the four vertical alignment screws on the bracket. 3. Loosen the horizontal alignment nut. 4.
