not
be

CDMA2000 1X services
The Sierra Wireless SB555 modem operates over a type of wireless
network called CDMA (Code Division Multiple Access).
CDMA technology provides a variety of connectivity features,
depending on your service provider and account:
•
high-speed packet data, sometimes known as 1xRTT, this
supports Internet connections with data rates up to 153.6 kbps
(downlink) and 76.8 kbps (uplink). Actual speed will depend
on the network.
•
Circuit switched (dial-up) data
, using the earlier CDMA
IS-95 specification, supports data connections to any dial-in
service at rates up to 14.4 kbps.
•
SMS (Short Message Service),
allows you to send and
receive short text messages using the SB555 modem.
A CDMA service provider account
Companies that operate CDMA networks and provide access to these
networks are called
service providers
. You must have an account with
a CDMA service provider to use the SB555 modem.
Each SB555 has been provisioned at the factory for use with a
particular service provider. This sets the SB555modem to use
particular radio channels and enable services specific for that provider.
The process of setting up your account is called
activation
. Activation
involves action by the service provider and configuration of the SB555
modem. The procedure to configure (activate) your SB555 modem is
covered in “Activation” on page 5.
