Back in December, a FCC pronounced that it had conducted expostulate tests of T-Mobile, Verizon, and U.S. Cellular’s networks and found that a carriers had skewed their farming coverage. The FCC pronounced that it won’t retaliate a carriers since they “did not find a amply pure violation”, yet T-Mobile has still taken a time to respond to a FCC’s report.

T-Mobile pronounced in a filing this week that FCC’s strange news used a “flawed corroboration process” and that a group “failed to follow commonly-accepted coverage contrast procedures as good as a possess MF-II instructions.” T-Mo afterwards goes on to call out 4 ways in that it believes a FCC done errors:

  • the sampling was intensely singular and not statistically sound, regulating usually a singular contrast indicate for any grid;
  • in transgression of a FCC’s possess requirement to magnitude outward coverage, staff conducted expostulate tests regulating handsets mounted inside cars, that is deliberate in-vehicle coverage;
  • testers unsuccessful to commend or pill a fact that their device was sealed onto a 3G vigilance while attempting to exam 4G speeds; and
  • the Staff Report contains apparent dimensions errors

T-Mobile afterwards goes into some-more fact about a errors that it believes a FCC made. For example, it says that a FCC’s outward contrast consisted of usually 7 exam locations in dual states and that a still tests were done during a locations usually once.

“This is deficient from a statistical basement to form conclusions per specific locations and is unconditionally unsound to form a basement for conclusions about coverage,” T-Mo argues.

T-Mobile also says that regulating phones mounted inside a automobile resulted in around 6db of vigilance attenuation due to blockage from a vehicle.

Additionally, T-Mo argues that a series of a “failed” tests occured when a phone was on a 3G vigilance even yet it was in an area with 4G coverage. T-Mobile suggests that a exam phone might have been inadvertently sealed onto a 3G signal. For example, a FCC’s contrast on Apr 1, 2019 showed 109 unsuccessful samples on 3G in areas where 4G LTE was available, T-Mo says.

Finally, T-Mobile says that a FCC’s news contains “obvious dimensions errors” including mixed reports that had RSRP values that were outward of picturesque values. T-Mo points to some-more than 60 exam formula in Montana where a reported RSRP value was reduction than -150dBm and mostly had “clearly impractical values” like -222 or -218dBm while also display multi-megabit download speeds.

“T-Mobile is committed to providing accurate coverage information to consumers,” T-Mo says in a end of a filing. “We demeanour brazen to operative with Congress, a FCC, and wireless attention in substantiating an fit and pure wireless coverage mapping routine for a 5G Opportunity Fund and other open routine initiatives in a future.”

The FCC creatively conducted these tests since of concerns that some carriers might have farfetched their coverage in maps submitted as partial of a Mobility Fund Phase II auction. This acquiescence routine helps a FCC establish where it should allot adult to $4.53 billion over 10 years.
