Methods and apparatus to scan a wireless communication spectrum

摘要

Methods and apparatus are disclosed to scan a wireless communication spectrum. An example method disclosed herein includes causing a first scanner to determine, for a frequency of a wireless communication spectrum, a decoded base station identifier, causing a second scanner to determine a plurality of signal strengths at the frequency without determining a base station identifier, and determining that the base station identifier is associated with a subset of the plurality of signal strengths by comparing at least one of timestamps and locations associated with the base station identifier and the plurality of signal strengths.

1. A method to improve data correlation from multiple scanners comprising:
identifying, with a processor, a deficiency in a first measurement record from a first scanner that has captured signal strength measurements of a wireless communication spectrum; determining a type of the deficiency in the first measurement record; when the type of the deficiency is associated with an insufficient location measurement, correcting a lack of a base station identifier in the first measurement record by correlating the first measurement record from the first scanner to a second measurement record including the base station identifier from a second scanner based on timestamp information indicating the second measurement record corresponds to a first time window, the timestamp information being in the first and the second measurement records; and when the type of deficiency is not associated with the insufficient location measurement, correcting the lack of the base station identifier in the first measurement record by correlating the first measurement record from the first scanner to the second measurement record including the base station identifier from the second scanner based on geographic location information indicating the second measurement record corresponds to a same physical location as the first measurement record, the geographic location information being in the first and the second measurement records.
