The Cisco® Connected Grid 2G/3G Cellular Modules are 3G wireless WAN connections for the Cisco 1000 Series Connected Grid Routers (CGR 1000 Series). The ruggedized 3G cellular modules and CGR 1000 routers together provide a versatile communications platform for a diverse set of field area network (FAN) and Internet of Things (IoT) deployments. They also support and extend utility applications such as Advanced Metering Infrastructure (AMI), Distribution Automation (DA), integration of Distributed Energy Resources (DER), and Remote Workforce Automation to endpoints in the grid.
Product Overview
Cisco Connected Grid 2G/3G Cellular Modules deliver service provider−based (public) wireless WAN connectivity for Cisco 1000 Series Connected Grid Routers (CGR 1000). These modules support the 3G standards for evolved High-Speed Packet Access (HSPA+) and Evolution-Data Optimized (EV-DO) Rev A. They're also backward-compatible with the following 2G/3G cellular network technologies:
• High-Speed Packet Access (HSPA)
• Universal Mobile Telecommunications Service (UMTS)
• Enhanced Data Rates for Global Evolution (EDGE)
• General Packet Radio Service (GPRS)
• EV-DO Rev 0/1xRTT
Connected Grid Cellular Modules have two variants:
• Global System for Mobile Communications (GSM) and UMTS models are based on 3GPP. They support HSPA+, HSPA, UMTS, EDGE, and GPRS.The ruggedized cellular module and the CGR1000 routers provide a versatile communications platform for a diverse set of FAN and IoT deployments for smart utility grids.
• Code Division Multiple Access (CDMA) models are based on 3GPP2. They support EV-DO Rev A/Rev 0 and 1xRTT.

There are five SKUs in the Cisco Connected Grid 2G/3G Cellular Module family. They offer utilities a choice of different technologies, carriers, and regions, as defined in Table 1.
Table 1. Cisco Connected Grid 2G/3G Cellular Modules for CGR 1000 Series
1 For 900 MHz-based AMI deployments, a CGM-3G-HSPA-G cellular module should be used (CGM-3G-HSPA-AB-G should not be used).
Utilities that need to improve business continuity and reduce operating costs should consider these modules. When they add a service provider wireless data plan, utilities gain a rapidly deployable solution for remote sites. And these modules make full use of the network services provided by Cisco CGR 1000 routers.
Connected Grid 2G/3G Modules offer embedded intelligence (such as intelligent WAN sensing and modem reset). Links can be restored automatically, with no need for a service visit.
In addition, Connected Grid 2G/3G Modules provide detailed diagnostic information about the 3G WAN link so that utilities can troubleshoot connectivity issues and provide detailed performance logs to their service providers. Please refer to the software specifications in Table 3 for more details.
Since Connected Grid 2G/3G Cellular Modules can be deployed in many utility environments worldwide, they offer a variety of antenna and cabling options. They support indoor- and outdoor-rated antennas, omnidirectional stick antennas, flat-panel antennas, low-profile saucers, ceiling-mounted antennas, and standard dipole antennas. Refer to the antenna specifications (Table 4), cable specifications (Table 5), and accessories specifications (Table 6) for more details.
