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.

Abstract
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.

9. A tangible computer readable storage medium comprising instructions that, when executed, cause a machine to at least:
-
identify a deficiency in a first measurement record from a first scanner that has captured signal strength measurements of a wireless communication spectrum; determine a type of the deficiency in the first measurement record; when the type of the deficiency is associated with an insufficient location measurement, correct 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, correct 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. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. An apparatus to correlate data from multiple scanners comprising:
-
a first scanner to capture first signal strength measurements of a wireless communication spectrum to form a first measurement record; a second scanner to form a second measurement record by capturing second signal strength measurements of the wireless communication spectrum and determining a base station identifier associated with the second signal strength measurements; a timestamper to determine 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; a geographic locator to determine 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; and a correlator to; determine a type of deficiency in the first measurement record; when the type of the deficiency is associated with an insufficient location measurement, correct a lack of the base station identifier in the first measurement record by correlating the first measurement record to the second measurement record based on the timestamp information; and when the type of deficiency is not associated with the insufficient location measurement, correct the lack of the base station identifier in the first measurement record by correlating the first measurement record to the second measurement record based on the geographic location information. - View Dependent Claims (18, 19, 20, 21, 22, 23)
