Network speed map

A system comprising:

• a processor;
• and
• memory storing computer-executable instructions that, when executed by the processor, cause the system to:
• receive, from a plurality of communication devices within a geographical area, a plurality of data samples, each data sample including a Channel Quality Indicator (CQI) value and a geolocation;
• determine, for a subset of the data samples that specify geolocations within a bin within the geographical area, efficiency values that correspond to CQI values specified in the subset of the data samples;
• determine a spectrum efficiency value associated with the bin based at least in part on the efficiency values;
• estimate a data rate associated with the bin based at least in part on the spectrum efficiency value;
• create a network speed map of the geographical area that indicates at least the data rate associated with the bin;
• and
• cause presentation of the network speed map on a display of a user computing device.

A computer-implemented method comprising:

• receiving, by a server computer, from a plurality of communication devices within a geographical area, a plurality of data samples;
• determining, by the server computer, and for a subset of the data samples that specify geolocations within a bin within the geographical area, efficiency values that correspond to Channel Quality Indicator (CQI) values specified in the subset of the data samples;
• determining, by the server computer, a spectrum efficiency value associated with the bin based at least in part on the efficiency values;
• estimating, by the server computer, a data rate associated with the bin based at least in part on the spectrum efficiency value;
• generating, by the server computer, a network speed map of the geographical area that indicates at least the data rate associated with the bin;
• and
• causing, by the server computer, presentation of the network speed map on a display of a user computing device.
