The Federal Communications Commission yesterday posted a letter from U.S. Cellular Corp. documenting a recent ex-parte meeting between the wireless carrier and staff members from the FCC’s wireless telecommunications bureau. In the letter, U.S. Cellular Corp. says that its meeting with FCC staff was geared toward urging action on interoperability rules.
Specifically, U.S. Cellular Corp. told the FCC that it believes that all its commercial band 12 devices would pass band 17 interference testing consistent with 3GPP specifications. U.S. Cellular also told the FCC that it would be moving forward with VoLTE equipment deployment in 2013 and 2014.
U.S. Cellular Corp. expects VoLTE will reduce disparities between CDMA and GSM devices and that VoLTE would bolster the argument that CDMA carriers should have AT&T devices that are interoperable with Band 12.
