Chapter 1 Overview

This document provides the procedure necessary to install the CGR ACT Module 3 (CAM3) in the 1000 Series Cisco® Connected Grid Router (CGR). In addition to the physical installation of the Adaptive Communications Technology (ACT) module, a procedure for loading the ACTD application into the CGR Guest Operating System (GOS) is also provided. The ACTD application serves as a communication gateway between the CGR operating system (IOS) and the CAM3. A procedure for the installation of an external antenna is also included. An external antenna is required to ensure optimal radio performance when the CGR is deployed in a star configuration for battery-powered-device (BPD) deployments.

This document is intended for field installers who are familiar with the CGR, its function, and operation. The information in this document is complementary to the base CGR installation procedures and addresses the addition of the CAM3/ACTD and the external star network antenna.

Chapter 5 External Antenna Installation

This chapter describes two processes for external antenna installation:

• External Antenna Only

• External Antenna with RF Filter

Note: The requirement for the RF Filter is dependent on the geographic territory where the CGR is installed and used. The RF Filter is not required for North American deployments.

External Antenna Only

This section describes the installation of an external antenna in territories where an RF Filter is not required.

Placement

Antenna placement is one of the most important factors in determining overall system performance. Careful consideration must be given to proper antenna placement. Follow these general guidelines when determining the ideal location for a remote-mounted external antenna:

• Mount the antenna vertically.

• Mount the antenna in a location where there is a clear, unobstructed, 360-degree view of the horizon. The antenna receives and transmits in all directions. Objects such as building walls, nearby metal surfaces, or other obstructions might interfere with the proper operation of the antenna.

• Do not mount the antenna on a rooftop where nearby buildings are higher than the installation location.

• Do not mount the antenna near existing RF radiating antennas. If existing RF radiators are nearby, the horizontal separation distance must be a minimum of 30 meters and/or three meters of vertical separation. In instances where nearby RF radiators are present, conduct an inter-modulation interference study to evaluate the potential for interference and any effects it may have on system performance. Consult your Itron systems engineer for more information.

• Height is preferred for optimal performance. Itron recommends installing the antenna no higher than 30 meters.

A side arm antenna installation must be done if the antenna is mounted where it does not have an unobstructed 360-degree view. Refer to the following guidelines for a side arm antenna installation:

OpenWay® Riva CAM3 Installation Guide 17

Proprietary and Confidential

External Antenna Installation

• The minimum standoff distance is 60 centimeters, where the interfering structural members are 10 centimeters or less in diameter and spaced more than two meters apart.

• For structural members between 10 and 25 centimeters in diameter, use a sliding scale of

0.6 to 1.5 meters (for example, a 60-centimeter standoff at 10-centimeter diameter to a 150-centimeter standoff at 25-centimeter member diameter).

Disconnecting the CGR Cables

1. Disconnect the power source from the CGR and remove the power cable.

Callout Number Description

1 CGR power cable

2. Check the SYS LED. To confirm that the router is powered off, verify that the SYS LED is off. The SYS LED is on the bottom exterior of the router enclosure. If the SYS LED is still on, the BBU must be disconnected after the CGR door is opened.

6. Make sure the antenna holder and the adapter plate are flush on all sides. See the following illustrations.

7. Attach the antenna to the mounting bracket.

a) Push the 1¾-inch bolt through the antenna holder, the remote mount adapter plate,

and the mounting bracket. b) Place the flat washer on the bolt. c) Place the split washer on the bolt. d) Add a drop of anti-seize lubricant to the nut and attach the nut to the bolt.

8. Replace the black rubber bumper on the end of the antenna.

External Antenna with RF Filter

This section describes installing the RF Filter to an existing pole-mounted CGR application that uses the external antenna option. To install the CGR, refer to the CGR installation procedure in the Cisco 1240 Connected Grid Router Hardware Installation Guide.

External Antenna Installation

An external antenna is required to ensure optimal radio performance when the CGR is deployed in a Star configuration for battery powered device (BPD) deployments. Standard height external antennas are mounted directly above the CGR (3–5 feet above the CGR) and connected to the RF Filter with an external RF cable. External antennas can be mounted at an extended height above the CGR. The coax RF cable from the RF Filter to the antenna will be locally sourced to the required length needed for specific antenna mounting locations (½" superflex is recommended for runs less than 35 feet).

The following illustration indicates how the external antenna and RF filter are connected to a CGR.

Placement

• Mount the antenna vertically

• Mount the antenna in a location where there is a clear, unobstructed, 360-degree view of the horizon. The antenna receives and transmits in all directions. Objects like building walls, nearby metal surfaces, or other obstructions might interfere with the proper operation of the antenna.

• Do not mount the antenna on a rooftop where nearby buildings are higher than the installation location.

• Do not mount the antenna near existing RF radiating antennas. If existing RF radiators are nearby, the horizontal separation distance to the radiator must be a minimum of 30 meters and/or three meters of vertical separation. In instances where nearby RF radiators are present, conduct an inter-modulation interference study to evaluate the potential for

interference and any effects it may have on system performance. Consult your Itron systems engineer for more information.

• Height is preferred for optimal performance. Itron recommends installing the antenna no higher than 30 meters.

Caution: Do not install a 5.5 dBi antenna directly on the CGR/CAM3. Antenna installation directly on the CGR/CAM3 will compromise mechanical integrity and will not meet the compliance requirements.

A side arm antenna installation must be done if the antenna is mounted where it does not have an unobstructed 360-degree view. Refer to the following guidelines for a side arm antenna installation:

•

The minimum standoff distance is 60 centimeters, where the interfering structural members are 10 centimeters or less in diameter and spaced more than two meters apart.

• For structural members between 10 and 25 centimeters in diameter, use a sliding scale of

0.6 to 1.5 meters. (For example, a 60-centimeter standoff at 10-centimeter diameter to a 150-centimeter standoff at 25-centimeter member diameter.)
