A consortium of regional wireless network operators, including Cavalier Wireless, C Spire Wireless, Continuum 700, King Street Wireless, MetroPCS, U.S. Cellular, and Vulcan Wireless, today submitted a test report to the Federal Communications Commission that contradicts claims made by AT&T with respect to 700MHz roaming. The companies submitted the report in response to the FCC's call for lower 700MHz device interoperability studies. The report used commercially available AT&T equipment and "conclusively demonstrates that the interference concerns AT&T has alleged as the basis for its use of an essentially proprietary band (Band 17) in the lower 700MHz spectrum, which effectively prevents competitors’ use of lower 700 MHz A Block licenses, are unsupportable." The companies say they performed tests both in the laboratory and in the field, and conclude that "Band Class 12 devices that comply with 3GPP performance specifications would exhibit normal performance in a commercial system deployment using the Lower B and C Blocks." Were AT&T to use Band Class 12 rather than Band Class 17, there would be no interference threats. AT&T hasn't responded publicly to the group's claims.

Vulcan Wireless?

No wonder why they debunked AT&T's interference claims, CEO Spock said it was highly illogical. Laughing Laughing Laughing
It's serious business. The behemoth carriers will starve these small carriers without roaming agreements. One day there will no longer be voice...just Voice over LTE. If Verizon and AT&T shut down their voice networks and only have data AND that da...

"AT&T hasn't responded publicly to the group's claims."

And they won't.

Someone explain

the difference between "Band Class 12" and "Band Class 17?"
AT&T uses the lower 700 band, while Verizon uses upper 700
