ABSTRACT:
Described is a system comprising a computing device, a wireless computing unit and a network management arrangement (“NMA”). The NMA receives a first signal and a second signal from the computing device. The NMA forwards the second signal to the unit and receives a third signal from the unit which is an acknowledgment of receipt of the second signal. The NMA determines a first time value indicative of a difference between a time of receipt of the first signal and a time of receipt of the second signal. The NMA compares the first time value to a first threshold range to generate a first output data. The NMA determines a second time value indicative of a difference between a time of transmission of the second signal and a time of receipt of the third signal. The NMA compares the second time value to a second threshold range to generate second output data. The NMA executes a response procedure as a function of at least one of the first and second output data.
