CDMA 3G services
The modem operates over a type of wireless network called
(Code Division Multiple Access).
CDMA 3G technology provides a variety of connectivity
features, depending on your service provider and account:
•
Rev. A supports Internet connections with data
rates up to 3.1
(downlink from the network) and
1.8 Mbps (uplink to the network). Average data rates are
450‐800
(downlink from the network) and
300‐400 Kbps (uplink to the network). Actual speed
depends on the network conditions.
•
Rev. 0 supports Internet connections with data
rates up to 2.4
(downlink from the network) and
153

400‐700 Kbps (downlink from the network) and

and connect to any web site that is accessible through the
Internet, or access other Internet services (such as e‐mail).

occurring. If data transmission stops for a period of time
(determined by the network), the connection becomes
