2. Overview
In this document all the basic functions of a mobile phone are taken into account; for
each one of them a proper hardware solution is suggested and eventually the wrong
solutions and common errors to be avoided are evidenced. Obviously this document
cannot embrace the whole hardware solutions and products that may be designed.
The wrong solutions to be avoided shall be considered as mandatory, while the
suggested hardware configurations shall not be considered mandatory, instead the
information given shall be used as a guide and a starting point for properly
developing your product with the Telit GC864-QUAD / PY module. For further
hardware details that may not be explained in this document refer to the Telit GC864-
QUAD / PY Product Description document where all the hardware information is
reported.
NOTICE:
(EN) The integration of the GSM/GPRS GC864-QUAD / PY cellular module within user
application shall be done according to the design rules described in this manual.
The information presented in this document is believed to be accurate and reliable.
