The Cisco® Connected Grid Cellular Modules are 3G and 4G LTE wireless W AN connections for the Cisco 1000 Series Connected Grid Routers (CGR 1000 Series). The ruggedized 3G and 4G LTE 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/4G LTE Cellular Modules deliver service provider-based (public) wireless WAN connectivity for Cisco 1000 Series Connected Grid Routers (CGR 1000). These modules support the 3G or 4G LTE standards for evolved Long Term Evolution (LTE), 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 The Connected Grid 2G/3G 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. The Connected Grid 2G/3G/4G LTE Cellular Modules support the latest Third-Generation Partnership Project (3GPP) Release 9 Category 3 LTE standards.
