1xEVDO (Revision A)

1xEVDO Revision A is the latest improvement of 1xEVDO Revision 0. Revision A provides greater data
access speeds than Revision 0, is more efficient in its use of airlink resources, provides a more synchronic
broadband experience, and supports prioritization and delivery of individual information packets based on
application type or user profiles. Revision A is capable of transfer speeds of up to 3.1 Mbps in a single

1.25 MHz FDD carrier, and speeds up to 800 kbps in commercial networks.

Cellular Technology Speed Influences

Although the 3G CDMA NIM is capable of operating at any of the available speeds, transfer rate and
signal type will depend upon the coverage area in which the unit is operating. Performance decreases as
proximity to the cell tower decreases, and performance decreases as the number of cell tower users
increases. The 3G CDMA NIM will operate at the fastest speed available in the coverage area. To verify
the speeds available in your area, contact your cellular provider.
