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 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 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.
You must set up an account with a service provider for each MP modem you
install. After installing the MP modem software, you must configure it to use an
account.
The ability of the MP modem to obtain service and the type of service obtained in
any area is determined by several factors:
Network proximity and 1x or EV-DO CDMA availability
To obtain service, you must be within the coverage area of a network operating in
one of the radio frequency bands supported by the MP modem. The type of
connection depends on the service available in that area. For example, there are
areas with 1xservice in which EV-DOhas not yet been implemented.
If you are within the coverage of a network operated by a different
Roaming
service provider, your ability to obtain service depends on whether a roaming
agreement exists between your service provider and the one operating your
current local network. There may be additional fees for roaming service. Contact
your reseller or service provider for information.
Your account may restrict usage of certain networks or may
Account provisions
limit your connection time or data transmission.
Supported CDMA radio frequencies
CDMA networks operate on two sets of radio frequency bands. The MP modem is
a dual-band product that operates on both bands:
•
1900 MHz (also called the PCS, or Personal Communications Services,
band)
•
800 MHz (Cellular band)
Receive diversity
The MP modem supports receive diversity for improved signal reception. Receive
diversity uses two antennas to enhance the quality of the signal, but does not
extend the MP modem's coverage area.
