About CDMA
The MP modem operates over
•
• High Speed Downlink Packet Access (HSDPA) — up to 3.6
megabits per second (Mbps)
a type of wireless network called Code Division Multiple
Access (CDMA). CDMA Third Generation (3G) technology
provides a variety of connectivity features, depending on your
service provider and account:
• 1x Evolution ‐ Data Optimized Revision A
(1xEV ‐ DO Rev. A) supports Internet connections with data
rates up to 3.1 Megabits per second (Mbps) downlink from
the network and 1.8 Mbps uplink to the network. Average
data rates are 450 ‐ 800 kilobits per second (kbps) downlink
and 300 ‐ 400 kbps uplink. Actual speed depends on
network conditions.
• 1xEV ‐ DO Revision 0 (Rev. 0) supports Internet connections
with data rates up to 2.4 Mbps downlink and 153 kbps
uplink. Average data rates are 400 –700 kbps downlink and
40 ‐ 80 kbps uplink. Actual speed depends on network
conditions.
• 1x supports Internet connections with data rates up to
153 kbps. Actual speed depends on the network condi ‐
tions.
• Circuit switched (dial ‐ up) data, using the earlier CDMA
IS ‐ 95 specification, supports data connections to any dial ‐
up service at rates up to 14.4 kbps.
The MP 595 modem is primarily designed to provide 1x or
better data connections but it also allows for Circuit
Switched Data (CSD) connections in areas that have
CDMA IS ‐ 95 coverage but no 3G (1xEVDO or 1x) high ‐
speed packet service.
Quick Net Connect (QNC) provides a simplified way to
dial into an Internet connection using CSD, assuming CSD
is supported by your service provider.
Once a connection is established, you can open your browser
and connect to web sites and access other Internet services
such as e ‐ mail.
CDMA account and coverage
You must set up an account with a CDMA service provider for
each MP modem you install. After installing the MP modem
software, you must configure it to use an account.
