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.
