Antenna Detect

Future hardware PCB change, an "ANT_DET_N" (Antenna Detect –
active low) line




Software will be able to determine whether the radio is receiving RF via the
antenna or the RF connector
When ANT_DET_N is low, RxLevOffset_1_[Band] is applied; if this line is not
low then RxLevOffset_2_[Band] is applied.
State of ANT_DET_N will be interrupt driven so that the phone will not have
to wake up periodically and poll this signal.
This feature provides the following benefits:






Generally faster camping upon power-up.
Less frequent “No Service” displays (detach from network)
Faster removal of “No Service” displays (re-attach to network)
Improved standby current drain due to less frequent channel scanning.
Remedies a large competitive disadvantage in camping performance,
relative to the Nokia 3390.
The Nokia unit exhibits a similar RxLev offset.
