2.2.3 HSDPA Throughput Rates
The peak download speed is rated up to 1.8 Mbps for the Ericsson W20
and 3.6 Mbps for the Ericsson W21 and Ericsson W25. The peak up-link
speed is 384 kbps. The rated HSDPA peak download speeds will
eventually evolve up to 14.4 Mbps with enhanced radio performance
(increased modulation and coding schemes) according to the table below
(current W2x rated peak speeds highlighted):

However peak upload speeds are only possibly with normal usage in a cell
and with optimal signal conditions. Typical download speeds experienced
by the users with multiple concurrent voice and data users in the cell,
ranges from 0.6 Mbps to 1.1 Mbps on average with current W2x series
radio configuration according to simulations in urban and suburban
environments. This rate will eventually evolve up to 6-7 Mbps with future
radio configuration updates of the W2x series.
