Librem 5 FCC Certification

I’m relieved that there will no longer be questions about the FCC certification.

If anyone wants to read the documents from the FCC tests, they are available here:
https://apps.fcc.gov/oetcf/eas/reports/ViewExhibitReport.cfm?mode=Exhibits&calledFromFrame=Y&application_id=EyPB2%2BlYJby%2BsY6aQJj3mQ%3D%3D&fcc_id=2AT9R-LIBREM5

Just some random info for people who are curious:

  • It only took 5 days for the FCC certification to be granted. Purism submitted the FCC application on July 17 and it was granted on July 22. In contrast, it took 10 days for the PinePhone.
  • The actual testing took place in Shenzhen LCS Compliance Testing Laboratory Ltd. between April 26, 2021 and May 31, 2021, which issued its report on June 18, 2021. It took 3 months to get the FCC certification from the start of the testing, which is relatively slow. I have heard of companies getting their FCC certification in less than 2 months.
  • I can’t find any mention of which cellular modem was tested in the documents, but I would assume that it was the Broadmobi BM818, and Purism will have to do separate testing for the PLS8 modem.
  • I was disappointed that Purism requested that the following information that was submitted to the FCC not be publicized since Purism considers it to be confidential: Schematic, Block Diagram, Parts List, Operational Description, Tune-up Procedure, and Declaration of Software Security Requirements For U-NII Devices. I don’t see any reason why Purism should hide this info from the public.
  • I was happy to see the photo of the 18W charger, which supports USB Power Delivery 3.0 at 5V-3A, 9V-2A and 12V-1.5A.
  • I can’t figure out how to compare the L5’s SAR measurements with other phone models. For example, here is what is listed for the Xiaomi Redmi Note 10 Pro at gsmarena.com:
SAR 1.09 W/kg (head) 1.06 W/kg (body)
SAR EU 0.60 W/kg (head) 0.99 W/kg (body)

I can’t find this info listed as clear numbers in the L5’s documents. Does anyone know which numbers are being used?
