CTIA and Big 3 US carriers oppose D2D in 5G bands

CTIA and AT&T, Verizon and T-Mobile urged the FCC to drop the 2.5GHz and 3.45GHz bands from draft rules for Supplemental Coverage from Space and direct-to-device service. The carriers argue TDD-based 5G bands cannot coexist with FDD satellite links without harming terrestrial networks.

• FCC votes this week on making 482MHz more spectrum available for SCS
• T-Mobile: up to 96% of a cell site's uplink area could be lost
• Uplink speeds could drop 88–99% where satellite coverage exists
• Carriers want 2.5GHz and 3.45GHz removed from the draft
