The document discusses the visualizing of mobile broadband data by the Federal Communications Commission (FCC), highlighting the use of a mobile app that collects data from nearly 100,000 mobile installs. It describes the architectural development using MongoDB and the creation of maps to represent carrier performance. The planned release of a web application and additional resources is set for August 2014, inviting public participation in data collection.

available in Google Play and iTunes App Store

4. "I like the idea of this app but it's not that useful
when I can only see my data. I'm waiting to see if
they release their heat maps & infographics of
carrier performance in Nov 2014 like they
promised... "

6. How the Gov't
normally
releases info

7. There is a better way

8. Feeling Spatial

10. xkcd on Heat
Maps

11. Hex Binning

12. Some early examples

13. Later Versions
(based on early draft data)

14. SQL approach was good for early
investigation, but not for delivering
a useful product to consumers.
Enter MongoDB

15. Architecting the System

16. MongoDB

17. Importing the Speed Test Files

18. Aggregation
Validated Mobile tests are stored in a collection for
aggregation.
$geoIntersects operator is used to determine the geographies that
each test is contained by.

19. Aggregation

20. Now, Let's Make a Map!

21. Actually, let's make 36 maps!

22. Developing the API
/api/mmba/carrier/verizon.json?
lat=34&lon=-118.2
json, jsonp, geojson, and xml
are supported
if (validLatLon(lat, lon)) {
console.log('lon ' + lon);
console.log('lat ' + lat);
lat = Number(lat);
lon = Number(lon);
geo_find = {geometry: { $geoIntersects: { $geometry: { type: 'Point', coordinates: [lon, lat] }}}};
}

23. Developing the UI
Some inspiration from the
Yahoo Weather App

24. Iterate the Design

25. Finish with
something
everyone is
proud of

26. Putting it all together
Planned Release in August 2014:
Web application, API, Developer
Resources, Data Download, and all
source code released on GitHub.

27. Next Steps:
Deploy the web
application
Start the next cycle.
Get more data!
