CDMA and GSM / UMTS Mini Card Hardware Integration Guide
Note: When performing RF
tests, use a test platform similar
to those shown in
(page 98) and
(page 99).
Note: The GPS receiver does
not need to be tested for UMTS
(MC878x) or CDMA (MC57xx)
modules supporting diversity
because RF connectivity is
validated by testing the diversity
receiver in Step 14.
Note: To power-off the module,
drive W_Disable# low for the
required minimum period. See
State change: Power off / on
page 23 for details.
Note: To install minicom, you
must have root access, or be
included in the sudoers list.
