Wireless Carrier Claims versus Customer Performance

In March 2014, Jim Warner from the University of California, Santa Cruz, explored the economic implications of exaggerated wireless claims, particularly regarding over-subscription issues that can diminish performance during peak usage. The impact of coverage quality, both indoors and outdoors, is assessed using a crowd-sourced methodology by the FCC and CPUC to collect relevant data. This study analyzes Verizon's LTE performance in a specific survey area, detailing upload and download speeds, ping times, and building penetration tests, providing crucial insights for consumers.

Presentation Transcript

  1. Wireless Carrier Claims versus Customer Performance Jim Warner University of California Santa Cruz March 2014

  2. Exaggerated claims might have an economic impact. • What about over subscription reducing performance during high use? • What is the effect of indoor v outdoor coverage? Great questions, but not in 10 minutes. • FCC and CPUC will employ crowd source approach to get data.

  3. Claim: almost perfect LTE

  4. Small LTE extended area

  5. Verizon reports to the CPUC • Border shows 5 sq mile survey area • Claim: 10-25 Mb/s up • Claim: 3-6 Mb/s down • Elevation: 400 ft to sea level • Area has 6 cell sites

  6. Survey method • Verizon LTE 7 inch tablet • Measurement at every street intersection • No do overs • Ookla speed test

  7. Links • Data for each measured point: upload and download speed, ping time and coords http://people.ucsc.edu/~warner/verizon-SC.kml • Test of building envelope penetration http://people.ucsc.edu/~warner/in-bldg CPUC data in KML format • http://people.ucsc.edu/~warner/mobile-test/
