CTIA, AT&T propose different frameworks for 28 GHz sharing

Both CTIA and AT&T are proposing frameworks for sharing spectrum with satellite operators, but they're not the same framework. AT&T's guidelines for the 28 GHz band were developed with EchoStar, Hughes Network Systems and Alta Wireless in a way that they say will allow fixed satellite services (FSS) and Upper Microwave Flexible Use (UMFU) licensees to fairly share the 28 GHz band outside the protected "urban core" areas. CTIA says its framework for sharing in the 28 and 37-40 GHz bands will enable both terrestrial and satellite services to make intensive use of the spectrum bands in a way that fairly balances the rights of all affected stakeholders.

"In both the 28 GHz and 37-40 GHz bands, while there are international allocations for FSS, the [Federal Communications Commission] has consistently given priority to terrestrial uses of these bands," CTIA Vice President of Regulatory Affairs Scott Bergmann said. "CTIA believes that this prioritization should continue, especially in the most populated areas of the United States, to ensure that 5G mobile broadband services can be deployed."
