<p>The FCC Measuring Broadband America (MBA) Program's Mobile
Measurement Effort developed in cooperation with SamKnows Ltd. and
diverse stakeholders employs a client-server based anonymized data
collection approach to gather broadband performance data in an open
and transparent manner with the highest commitment to protecting
participants privacy. All data collected is thoroughly analyzed and
processed prior to public release to ensure that subscribers’ privacy
interests are protected.</p>
<p>Data related to the radio characteristics of the handset,
information about the handset type and operating system (OS) version,
the GPS coordinates available from the handset at the time each test
is run, the date and time of the observation, and the results of
active test results are recorded on the handset in JSON(JavaScript
Object Notation) nested data elements within flat files. These JSON
files are then transmitted to storage servers at periodic intervals
after the completion of active test measurements. This document
describes the JSON schema nested format of the radio, handset, active
test result and other data recorded on the handset prior to
transmission to the storage infrastructure.</p>
