1. A monitoring system for monitoring one or more objects by an electronic device, the system comprising:
- a define module for defining a distance threshold between the electronic device and the one or more objects comprising a radio frequency identification (RFID) tag, the RFID tag comprising associated information of the corresponding one or more objects;
a signal module for radio frequency (RF) communications with the one or more objects by transmitting RF signals to the RFID tag of the one or more objects and by receiving corresponding RF signals from the RFID tag of the one or more objects, the signal module further comprising a timer; and
an alarm module for calculating a distance between the electronic device and the one or more objects based on a round trip time of the corresponding RF signals calculated by the timer of the signal module, and for generating monitoring alerts upon detection that the distance is greater than the distance threshold.

7. A computer-implemented method for monitoring one or more objects by an electronic device, the method comprising:
-
defining a distance threshold between the electronic device and one or more objects comprising a RFID tag; transmitting RF interrogation signals to the RFID tag of the one or more objects; receiving the RF signals indicative of associated information of the RFID tag; calculating a distance between the electronic device and the one or more objects basing on a round trip time of the RF signals by a timer of the electronic device; and generating monitoring alerts upon detecting that the distance is greater than the distance threshold. - View Dependent Claims (8, 9, 10, 11)

12. A computer-readable medium for monitoring one or more objects, the computer-readable medium having stored thereon instructions that, when executed by an electronic device, cause the electronic device to:
-
define a distance threshold between the electronic device and one or more objects comprising a RFID tag; transmit RF interrogation signals to the RFID tag of the one or more objects; receive the RF signals indicative of associated information of the RFID tag; calculate a distance between the electronic device and the one or more objects basing on round trip time of the RF signals by a timer of the electronic device; and generate monitoring alerts upon detecting that the distance is greater than the distance threshold. - View Dependent Claims (13, 14, 15, 16, 17)
