2.1 Application Descriptions
The CDMA Wireless Data Modem is a complex consumer communications instrument that relies
heavily on both digital signal and embedded processor technologies. The Wireless Data Modem
manufactured by AnyDATA.NET supports Code-Division-Multiple-Access (CDMA). This operates in
800MHz CDMA and 1900MHz PCS spectrum.
In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data
Modem, AnyDATA.NET has successfully developed the EMIV-DUAL V2.0. The EMIV-DUAL V2.0 is
AnyDATA.NET’s latest compact Wireless Data Modem operating in 800MHz CDMA and 1900MHz
PCS spectrum, also contains complete digital modulation and demodulation system for CDMA standards
as specified in IS-95 A/B and IS-2000.
The subsystem within the EMIV-DUAL V2.0 includes a CDMA processor (MSM6050), an
integrated CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface
supporting forward link data communications of a rate of 153kbps.
The EMIV-DUAL V2.0 provides external interface. External interface includes the standard RS-232,
Digital Audio, External reset control, parallel LCD Display, Keypad, Ringer extension ports and R-UIM
for China market.
The EMIII-DUAL has the capability to power down unused circuits in order to dynamically
minimize power consumption.
