Introducing the MP Modem
Rev 1.5 Jul.08 9
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 1xEV-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 1x service in which 1xEV ‐ DO has not yet been
implemented.
Roaming If you are within the coverage of a network
operated by a different 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.
Account provisions Your account may restrict usage of
certain networks or may limit your connection time or data
transmission.
Supported CDMA radio frequencies
CDMA networks operate on two sets of radio frequency
bands. The MP 595 modem is a dual ‐ band product that
operates on both bands:
• 1900 MHz (also called the PCS, or Personal Communica ‐
tions Services, band)
• 800 MHz (Cellular band)
Receive diversity
The MP 595 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.
Connection methods
You can connect the MP modem to a USB, Ethernet (RJ45), or
serial (DB9) port on a computer. When connected to a USB or
Ethernet port, the MP modem behaves like a network card.
When connected to a serial port, the MP modem behaves like a
dial ‐ up modem.
