1xEV-DV

1xEV-DV is the last evolution expected for a CDMA2000-1X platform. The
1xEV-DV system will enable both voice and packet data services to share
the same resource FA; similar to 1xEV systems, but they have the packet
data throughput associated with 1xEV-DO systems.
Effectively, they are the introduction of 1xEV-DV is envisioned to meet or
exceed the capacity envisioned for 3X platforms and may have itself precluded
the purpose of implementing a 3X system. Data rates are envisioned
for 1xEV-DV to reach a peak rate of 5 Mbps with an average throughput of
1.2 Mbps. The current effort to develop 1xEV-DV has begun to question the
need for a 3X platform. However, that decision point has not arrived.
