The  aim  of  this  document  is  the  description  of  typical  hardware  solutions  useful  for  developing  a 
product with the Telit CE910 module. 

In this document all the basic functions of a mobile device will be taken into account; for each one of 
them a proper hardware solution will be suggested and eventually the wrong solutions and common 
errors  to  be  avoided  will  be  evidenced.  Obviously  this  document  cannot  embrace  all  hardware 
solutions  and  products  that  may  be  designed.  Avoiding  the  discussed  wrong  solutions  must  be 
considered  as  mandatory.  While  the  suggested  hardware  configurations  must  not  be  considered 
mandatory, the information given must be used as a guide and a starting point for properly developing 
a product with the Telit CE910 module. 

 

NOTE: 

The integration of the CDMA 1xRTT module within a user application must be done according to the 
design rules described in this manual. 

 

The  information  presented  in  this  document  is  believed  to  be  accurate  and  reliable.  However,  no 
responsibility  is  assumed  by  Telit  Communication  S.p.A.  for  its  use,  such  as  any  infringement  of 
patents  or  other  rights  of  third  parties.  No  license  is  granted  by  implication  or  otherwise  under  any 
patent rights of Telit Communication S.p.A. other than for circuitry embodied in Telit products. This 
document is subject to change without notice.
