A high data rate (HDR) version of Code Division Multiple Access 2000 (CDMA2000) that employs 16-QPSK modulation in support of a peak data rate of 2.4 Mbps on the downlink and 153 kbps on the uplink. In a fully loaded cell, 1xEV-DO supports average aggregate throughput of 4.1 Mbps on the downlinks and 660 kbps on the uplinks. 1xEV-DO can run in any band and can coexist in any type of network. See also 16-QPSK, CDMA2000, downlink, modulation, throughput, and uplink.
