Feature Descriptions
Integration Reduces Space, Power and Cost. The ModemModule CDMA integrates the controller, RF
transceiver, and antenna interface in one compact unit. This integration requires low power, low real estate
and provides an overall reduction in costs.
Reduces Development Time. The ModemModule CDMA can make your existing and next generation device,
machine, or system, communication-ready without requiring significant hardware changes to its design. It
actually provides faster time-to-market because it relieves the burden and expense of obtaining network and RF
approvals. This complete, ready-to-integrate wireless module allows you to enhance your product while you
focus on developing its core features.
Voice Features. The ModemModule CDMA provides telephony and Dual Tone Multi Frequency (DTMF)
functionality as well as QCELP (13K) and echo cancellation.
Short Message Services. The ModemModule CDMA offers SMS features such cell broadcast, Over the Air
Activation (OTA), OTASP, and OTAPA. The ModemModule CDMA is SMS Mobile as Originated and SMS
Mobile Terminated.
Compatible Supplementary Services. The ModemModule CDMA is compatible with supplementary services
such as call forwarding, call barring, multiparty, call waiting and call hold, calling line identification, closed user
group and call transfer.
Management Features. The ModemModule CDMA provides advanced management features including phone
book management, fixed dialing number, real-time clock and alarm management.
Industry-standard Modem Commands. The ModemModule CDMA provides industry-standard AT-style
commands for ease of integration into your existing software application.
ModemModule Pin-Out. The ModemModule CDMA interfaces easily with existing products through a standard
serial communication channel. The complete on-board RF transceiver interfaces with an antenna for direct
connection to wireless SMS, circuit-switched dial-up, or packet data networks. The ModemModule is a Data
Terminal Equipment (DTE) device with serial asynchronous protocol support. The serial DTE channel is capable
of transfer speeds to 230K bps and can be interfaced directly to a UART or micro-controller. It can be board-to-
board or board-to-cable mounted.
