Assisted global positioning system (AGPS)
capability is offered as an option to the
i.250-21 platform. By attaching Freescale’s
MCM29500 GPS processor and MC13240
GPS RF front-end IC to the i.250-21, and
licensing the SiRFLoc client software directly
from SiRF Technology, Inc., the i.250-21
customer has a complete AGPS solution that
is capable of supporting the E-911 U.S.
government mandate as well as a broad suite
of location-enabled applications where size,
cost and performance are critical. In addition,
Freescale will offer a GPS hardware
reference design and interface software to
simplify the integration of this optional GPS
Platform Development Environments
The i.250-21 platform is designed to simplify
the development process for a GSM/GPRS
product by organizing the tools and different
pieces of the solution into the following three
major development environments:
> Integrated development environment (IDE)
for software and man-machine interface
(MMI) development
• Application Development System (ADS)
• Software—GSM engine with
GPRS and MMI toolkit
• Supporting tools for
handset development
> Radio Test Environment (RTE) for radio
development and performance optimization
• Flash loader tool
• Radio tuning tool
> Manufacturing Test Environment (MTE) for
meeting type approval and production line
test requirements
• Test planning
