2. Overview 

 

 

2.1 Application Descriptions 

 

The  CDMA  Wireless  Data  Module  is  a  complex  consumer  communications  instrument  that  relies 

heavily  on  both  digital  signal  and  embedded  processor  technologies.  The  Wireless  Data  Modules 

manufactured  by  AnyDATA.NET  support  Code-Division  Multiple  Access  (CDMA).  This  operates  in 

both the cellular and PCS spectrum.   

In a continuing effort to simplify the design and to reduce the production cost of the Wireless Data 

Module,  AnyDATA.NET  has  successfully  developed  the  DT2000  series.  The  DT2000-Dual  is 

AnyDATA.NET

s latest compact Wireless Data Module operating in the Cellular and PCS spectrum. The 

DT2000-Dual also contains a complete digital modulation and demodulation system for CDMA standards 

as specified in IS-95 A/B and IS-2000. 

The  subsystem  in  the  DT2000-Dual  includes  a  CDMA  processor  (MSM5100),  an  integrated 

CODEC with an ear piece and microphone amplifiers, and an RS-232 serial interface supporting forward 

link data communications at a rate of 230.4kbps. 

The DT2000-Dual provides  an external interface that includes  the standard  RS-232, Digital  Audio, 

External reset control, LCD Display, Keypad, and Ringer extension ports.   

The  DT2000-Dual  has  the  capability  to  power  down  unused  circuits  in  order  to  dynamically 

minimize power consumption.
