The Cisco® Connected Grid router portfolio is designed specifically for the harsh, rugged environments often found in the energy and utility industries. These routers include the Cisco 2010 Connected Grid Router (CGR 2010), which is designed to support the communications infrastructure needs of the energy delivery infrastructure across the generation, transmission, and distribution sectors
Designed for highly secure, reliable, and scalable infrastructure, the CGR 2010 is an ideal platform to support Smart Grid and other energy delivery infrastructure needs of customers. The CGR 2010 has been extensively tested to meet the challenging substation compliance standards, including IEEE 1613 and IEC 61850-3. The CGR 2010 offers four module slots to utilize Grid Router WAN Interface Cards (GRWIC). These modules allow for WAN connectivity to both legacy networks such as ISDN, DSL, serial, etc., as well as new WAN technologies such as 4G Long Term Evolution (LTE).
Product overview
The Cisco Connected Grid 2G/3G/4G Multimode LTE GRWIC modules are designed for use with the Cisco 2010 Connected Grid Router (CGR 2010). These GRWICs provide second-generation (2G), third-generation (3G), and fourth-generation (4G) cellular technologies and are backwards-compatible with older technology. Suitable as both primary and secondary WAN connections, these GRWICs support the latest 4G standards (3GPP Release 8 LTE) as well as 3GPP and 3GPP2-based 3G and 2G access technologies, and transparent handoff from 2G/3G to 4G LTE.
These GRWICs support the 3GPP2 technologies of Code Division Multiple Access (CDMA) such as CDMA 1xRTT, Evolution-Data Optimized, or EVDO Rev 0 and Rev A. They also support the 3GPP technologies of the Global System for Mobile Communications (GSM) and Universal Mobile Telecommunications Systems (UMTS) such as GSM, EDGE, or Enhanced Data Rates for Global Evolution; General Packet Radio Service (GPRS); and High-Speed Packet Access (HSPA), which included High-Speed Uplink Packet Access (HSUPA) and High-Speed Downlink Packet Access (HSDPA). In addition, the new LTE 4G technology is supported.
Figure 1 displays the CDMA, EVDO, and LTE GRWIC.
These cards support various technologies, frequency bands, and regions around the world (see Table 1).
The Cisco 2G/3G/4G Multimode GRWICs are tightly integrated with the services provided on the Cisco 2010 Connected Grid Router. Utility and energy companies are looking for ways to reduce costs, increase revenue, and improve business continuity. The Cisco 2G/3G/4G LTE Multimode GRWICs, when coupled with a service provider wireless data plan, provide a cost-effective, rapidly deployable, reliable, and highly secure backup solution for primary and remote sites. With wireless data rates surpassing T1 speeds, 4G networks provide an alternative to wire-line backup solutions such as ISDN, cable, and DSL. If a network fails, the Cisco CGR 2010 routes mission- critical data to the Cisco 2G/3G/4G GRWIC for transmission across the wireless infrastructure. In addition, the router can distinguish different types of traffic and allow only mission-critical traffic to flow over the backup interface.

Note: Throughput depends on multiple factors such as RF interference, carrier network load, and network optimization.
Cisco 2G/3G/4G Multimode LTE GRWICs can be deployed in many environments found in the worldwide energy infrastructure. Therefore, the product comes with a multitude of antenna and cabling options to allow for deployments in multiple environments. The GRWICs support both indoor- and outdoor- rated antennas, and different types such as omni-directional stick antennas, flat-panel antennas, low-profile saucers, ceiling-mounted antennas, and standard dipole antennas. Table 3 provide details on the supported antennas.
