AirLink MP595 / MP595W Modem User Guide
About CDMA
The MP modem operates over 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
•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 aCDMA service provider for each MP modem you install. After installing the MP modem software, you must configure it to use an account.
