3G wireless networks support peak data rates of 144 Kbps at mobile user speeds, 384 Kbps at pedestrian user speeds and 2 Mbps in fixed locations (peak speeds), although some initial deployments were configured to support only 64 Kbps. The International Telecommunication Union (ITU) coordinates 3G standards through its International Mobile Telecommunications-2000 (IMT-2000) project and incorporates the key standards bodies, Third-Generation Partnership Project (3GPP) and 3GPP2.
