FCC Above 24 GHz Report and Order and Further Notice of Proposed Rulemaking

According to the FCC:

Today, we take a significant step towards securing the Nation’s future in the next generational evolution of wireless technology to so-called 5G. We build upon years of successful spectrum policy – including flexible use, unlicensed, and sharing policies – to create service rules for using four spectrum bands above 24 GHz. These high frequencies previously have been best suited for satellite or fixed microwave applications; however, recent technological breakthroughs have newly enabled advanced mobile services in these bands, notably including very high speed and low latency services. To promote the deployment of these highly beneficial technologies, we are acting quickly –- more quickly than most of our counterparts around the world – to establish a coherent framework built on a robust public record. In addition to this significant step forward, we will also continue to explore new opportunities to make additional bands available and to explore other issues, including robust Federal sharing, raised in the accompanying Further Notice of Proposed Rulemaking.

Boeing Petition for FSS Uplink Spectrum in 50.4-52.4 GHz

According to Boeing:

Currently, FSS V-band allocations exist for four and a half gigahertz of downlink spectrum (37.5-42.0 GHz, space-to-Earth). To this existing allocation, the Commission has appropriately proposed adding an additional one half gigahertz of downlink spectrum at 42.0-42.5 GHz in order to make more intensive use of this underused block while maintaining adequate protection for radio astronomy in the adjacent 42.5-43.5 GHz band. This action will create five gigahertz of FSS V-band downlink spectrum.

There are currently four gigahertz of allocated FSS uplink spectrum (47.2-50.2 GHz and 50.4-51.4 GHz, Earth-to-space) in the United States, although the upper most one gigahertz has not been designated for FSS use in Part 25 of the Commission’s rules. To realize the full benefits of nationwide broadband via high data-rate V-band FSS, the Commission should authorize FSS Earth-to-space operations in the 50.4-51.4 GHz band and allocate the 51.4-52.4 GHz band for FSS uplinks to create a full five gigahertz of paired spectrum for V-band FSS operations.
