Alina Selyukh and Marina Lopes report to Reuters that "The top U.S. communications regulator on Friday said he is asking all large U.S. wireless carriers to explain how they decide when to slow download speeds for some customers, after questioning Verizon Wireless about such a plan"
This follows the letter sent earlier to Verizon (See "The FCC "Deeply Troubled" by Verizon's LTE Optimization" - here) following the MNO's decision to expand its "optimization" policy to LTE and limit unlimited users in congested locations (see "Verizon Expands "Optimization" to LTE Subs to Fight Cell Congestion" - here).
Verizon's response to FCC worries was (here, by TheRegister) that it is the right thing to do and everybody does that (try to claim that in a trial): "The Commission Has Recognized the Reasonableness of this Form of Network Management .. Such Practices Are Widely Used Throughout the Industry and Have Been Widely Accepted [we are] Managing our 4G LTE to Ensure the Best Wireless Experience [and] With network optimization, our customers continue to be free to go where they want on the Internet and to use the applications, services and devices of their choice"
So ... if everybody does it, need to ask them as well.
Back to Reuters report - "AT&T Inc representatives did not immediately comment. A Sprint Corp spokeswoman said her company "goes to great lengths to be transparent about its network management practices," and will respond to Wheeler's letter as appropriate. "Our network practices are consistent with the Commission’s rules on the open Internet, are innovative and are good for consumers and competition," a T-Mobile US spokeswoman said."
