Installation

6.1 Inventory

The first thing an installer physically does once onsite is to check to see that all equipment and materials

have arrived, as well as to make sure all necessary documents and forms are available.

6.2 BWX 8415 Basestation Radio Unit (RU) Installation

6.2.1 Overview

Caution Only trained and qualified personnel should be allowed to install, replace, or service this

equipment. Statement 1030

Caution - Refer installation and service to qualified service personnel only. No user serviceable parts inside.

- Installation must be done in accordance with the instructions contained in this manual.

- Read these instructions before installing.

- Save these instructions.

Warning

Installation of the equipment must comply with local and national electrical codes.

Statement 1074

The Radio Unit (RU) is a lightweight unit that connects easily with the Antenna Unit (AU) to form the

complete BWX 8415 Basestaion (BS). All customer accessible connectors will be located on the bottom

of the RU (

Figure 6-1).

Note that the circuit cards inside the BS are not field replaceable. Therefore, if a severe fault occurs, the

entire unit is removed and replaced. The design intent is to cut down on the time it takes to troubleshoot

or otherwise have a field support person onsite.

(MORE DETAILS ONCE FIELD TEST KIT IS AVAILABLE) Step 8 After the calibration has been completed successfully, power down the RU. Disconnect the RU from the DC power source. Step 9 Disconnect the ground cable and DC power leads from the RU. Step 10 Disconnect the RF cables and GPS cable from the RU.

Step 4 Replace the faceplate covers. Be sure to insert the pin on the faceplate covers into the mechanical interlock holes on the AU and RU units, these holes should align when the RU is inserted into the AU.

Chapter 6 Installation 6.3.2 Install the GPS Antenna Cable P R E L I M I N A RY 6.3.1.1 Channel Filters In the BWX 8415 Basestation you have the option to: • 1 - Use a Channel filter: The functions of Channel filters are two-fold: (1) to shape the power amplifier out-of-band emission during transmission in order to meet FCC or other regulatory requirements; and (2) to provide high rejection for close-in jammers during the receive period. The latter improves receiver selectivity.

Each of the antenna elements in the AU are covered by the individual radomes on the panel. At all times handle the antenna carefully.

Figure 6-12 provides some general guidelines for avoiding adjacent interference. The illustration shows the horizontal and vertical separation in feet and in meters for panel antennas.

Chapter 6 Installation 6.3.5 Antenna Separation P R E L I M I N A RY Caution There can be no co-location of MC-SCDMA with Mobile WiMAX basestations. If 2 or more BSs are co-located on the same structure, they must run the same technology or be upgraded in the same maintenance window. Use frequency separation to minimize interference between a MC-SCDMA and Mobile WiMAX basestation. A reasonable frequency separation is 15 MHz for BSs that are 2 kilometers apart.
