3. LG Electronics Descriptions of HDR System Standardization of 1x EV-DO as part of cdma2000 1X Asymmetric Data Transmission with TDM/CDMA - Forward link : 38.4 Kbps - 2.4 Mbps - Reverse link : 4.8 Kbps - 153.6 Kbps  Dynamically assigned data rate adjusts as rapidly as every 1.67 msec, providing every subscriber with the best possible rate at any given moment  “ Always On ” Service Applicable Services : Multimedia, Online Game, File Download, VOD, etc.. HDR is optimized for the wireless internet service with full duplex IP connectivity between all the access terminals and hosts on the Internet. 2/13
