Dear Mr. Shapiro:

I am writing on behalf of Telefonaktiebolaget LM Ericsson (“Ericsson”) to request that Ericsson be permitted to respond by October 27, 2017 to your letter dated September 28, 2017 regarding the Securities and Exchange Commission Staff’s review of Ericsson’s Form 20-F for the Fiscal Year Ended December 31, 2016 filed on April 26, 2017. Ericsson requests the additional ten business days to permit it to complete the preparation and review of the requested response.

Please do not hesitate to call me at (202) 636-5804 with any questions.

Very truly yours,
