SYSTEM AND METHOD FOR DEVICE BEHAVIOR MODIFICATION BASED ON EXTERNAL ANTENNA DETECTION INSIDE RESTRICTED AREAS

摘要

A device behavior modification apparatus is provided to detect insertion of an external antenna into a portable communication device, and identify the external antenna as being either, e.g., a valid, FCC-approved external antenna or an invalid external antenna. The apparatus may determine whether or not an internal antenna is being utilized and/or has been substituted with the inserted external antenna. Depending on the type of external antenna inserted, the apparatus may react and effectuate changes to the operation of the portable communication device and/or the external antenna. Such behavior modification may include, e.g., reducing the RF signal power output or disabling the radio portion of the portable communication device altogether. Additionally, the apparatus may receive certain augmentative information to notify the apparatus or allow the apparatus to determine the region within which it is operating.
