Claim Text:
1. A non-transitory computer readable medium comprising instructions which, when executed by one or more hardware processors, causes performance of operations comprising: obtaining samples corresponding to a first wireless signal, wherein the first wireless signal is received in a first time period; determining a signal strength of the first wireless signal from the samples corresponding to the first wireless signal received in the first time period; obtaining samples corresponding to a second wireless signal, wherein the second wireless signal is received in a second time period different than the first time period; determining a signal strength of the second wireless signal from the samples corresponding to the second wireless signal received in the second time period; responsive to determining that a difference between the signal strengths of the first and second wireless signals is greater than a threshold, determining that the first wireless signal is transmitted from a first source and that the second wireless signal is transmitted from a second source different from the first source; obtaining samples corresponding to a third wireless signal received in a third time period; determining a signal strength of the third wireless signal from the samples corresponding to the third wireless signal received in the third time period; determining a difference between the signal strengths of the first and third wireless signals is less than the threshold; and estimating that a duration of a wireless signal burst from the first source is longer than the first time period.
