【美国FCC计划开放5G中频频段,缩减数字鸿沟】美国联邦通信委员会(FCC)正在计划开放5G的中频频段。委员会投票赞成了这一项命令,该命令将取消对拥有2.5GHz频谱的人的限制,包括肯尼迪时代的教育用途要求。美国联邦通信委员会声称,这些无线电波已经“未充分利用”多年,从理论上讲,它们可用于解决农村地区“缩小数字鸿沟”和推进现有的美国5G战略。http://www.looooker.com/?p=67600

FCC loosens rules to make 5G available in lower frequencies

It's eliminating educational use requirements in the process, however.

The FCC is acting on its plans to open up mid-band frequencies for 5G. The Commission has voted in favor of an order that would eliminate the restrictions on who can own 2.5GHz spectrum, including a Kennedy-era requirement for educational uses. These airwaves have been "underutilized" for years, the FCC claimed, and making them available will theoretically help with both "closing the digital divide" in rural areas and furthering the current US 5G strategy.

The order aims to preserve incumbents' existing private arrangements and provisions, and removes limits on leases in the future based on the FCC's rules for secondary markets. This should motivate carriers to build in rural areas, the FCC claimed. Accordingly, there's a "priority filing window" for rural tribal nations to claim unused 2.5GHz frequencies.

This could help the US catch up in some areas. Many 5G deployments in other parts of the world rely on mid-band data that might not be as fast as the ultra-wideband access in the US, but offers considerably better coverage. Existing American 5G tends to require a glut of cell sites (with accordingly slow rollouts) and often falls apart indoors due to the extra-high frequencies.

At the same time, there are concerns that the FCC is tossing away an opportunity to improve education in the name of commercial success. Commissioner Jessica Rosenworcel, who partly dissented on the order, said that the FCC effectively "burns this [educational] policy down" with no replacement. She instead suggested that the FCC conduct an incentive auction for 2.5GHz space and create a Homework Gap Fund to ensure that students can get online when they can't at home. While it's true that the spectrum largely went untapped, the FCC's measure effectively eliminates the chance to use it for the public interest.
