Mobile Testing Findings Presented to California Broadband Council

On Tuesday, November 18 in San Francisco, Ken Biba, CTO and Co-founder of Novarum, presented recent findings from the past five rounds of mobile field testing to the California Broadband Council. His six key themes were:

  • Mobile broadband continues to get much better VERY quickly (on average)
  • There is a wide variation in mobile broadband performance across California
  • Not all carriers are equal
  • Mobile broadband service is not just wireless access
  • Real and growing mobile digital divide
  • The bulk of California’s mobile network is still not yet VoIP ready
  • Measured service substantially less than advertised
Here's one of his graphs, showing estimated VoIP readiness:




Round 6 Testing Finished!

Our testers completed the sixth round of mobile field testing this week, well before the Thanksgiving holidays. A big thanks to everyone who made this possible: Tyler, David, Darren, YoungJoon, Jason, and the testers at CSU Chico and CSU Northridge. Also, a big thank you to the Computer Science and Information Technology Department at CSU Monterey Bay for the app and server support. Great job!

Our Testers Go To the End of the Earth

Breathtaking!

Odd Thing On The Way to a Testing Location...

From Steve Crews:
"Just up the road from location 2022 was the strangest thing I've come across so far this round, the Rice Shoe Tree, which apparently used to be a real tree that people did this to, until it was burned down by vandals:

Change! Data Card Testing --> Tablet Testing next Spring

Mobile field testing is staying current by transitioning from netbooks/data cards to tablets. The change will happen next Spring (2015), when we retire the trusty netbooks.

Other changes being considered are adding trace route to the field test software and CalSPEED in order to gather more data on backhaul networks.

Finally, we have re-started development for CalSPEED on the iPhone!

More on this later...

Round 6 Testing 25% Complete


We finished our second full week of Round 6 mobile field testing today. We are 1/4 of the way there. We did discover a problem wth UDP tests failing consistently on T-Mobile phones upgraded to Android 4.4. We tried rolling back to an earlier version of Android, but the phones don't allow us to do that. We are exploring a fix through our developers at CSU Monterey Bay and will be contacting T-Mobile as well.

CalSPEED update

We've been digging into analysis of the CalSPEED results, and to date, we've had over 6,000 tests performed. After removing tests not performed in California, we identified over 4,400 tests -- 44% of which were done on Verizon Wireless devices, 20% on Sprint, 16% on AT&T, and 15% on T-Mobile. The top devices used for testing were:

Samsung Galaxy S4 - 44% of tests
Samsung Galaxy S3 - 11%
Galaxy Tab 7.7 - 4%
DROID RAZR - 3%
Epic 4G - 3%
