US Regulators Clash Over 5G Rollout and Aircraft Safety
Late in 2021,US wireless companies were set to dramatically increase the performance of their fifth generation(5G)networks.Although they had been offering 5G service since 2019,they were transmitting data in sections of the electromagnetic spectrum that often are no faster than the fourth generation(4G)or that provide restricted coverage[1,2].On 5 December 2021,the two biggest companies,AT&T and Verizon,were scheduled to expand into the C-band,a range of mid-band frequencies often dubbed the"sweet spot"for wireless because it combines high speed with broad coverage(Fig.1)[2].
