Sharing

The National Telecommunications and Information Administration commented in response to the Federal Communications Commission’s Notice of Proposed Rulemaking addressing federal earth stations, launch spectrum, and operation of a new federal environmental sensing satellite. These issues are connected by the principle that the responsibilities of the FCC and NTIA to manage our respective spheres of spectrum use require continued adjustment to reflect the realities of their interdependence. Here, it means:

At the beginning of the COVID-19 pandemic, T-Mobile wrangled additional 600 MHz spectrum from a number of companies and from unused spectrum held by the Federal Communications Commission to bolster its capacity for Americans during a crisis. On July 27, T-Mobile filed a sixth application with the FCC f

The massive infrastructure bill making its way through the US legislature includes a section on spectrum auctions, including pre-auction funding for the Department of Defense (DoD) to research sharing and commercial use in the 3.1-3.45 GHz band. The section says once the bill is enacted, $50 million from the Spectrum Relocation Fund would be transferred to the DoD for research, planning and other activities for efficient spectrum use for the purpose of making the band available, including reallocating spectrum for shared federal and non-federal licensed users and conducting an auction. Shar

The Federal Communications Commission’s Wireless Telecommunications Bureau (WTB) and the National Telecommunications and Information Administration (NTIA) issued a joint Public Notice to provide information about the cooperative sharing framework for federal and non-federal coordination in certain defined areas where and when federal incumbents require continued access in the 3.45–3.55 GHz band. The notice provides information and guidance on the overall coordination process, as contemplated by the 3.45 GHz Band 2d R&O.

The Federal Communications Commission denied an appeal from a California-based company that repeatedly disregarded its obligations to reasonably share a channel with other licensees. Mobile Relay Associates disputed the FCC Enforcement Bureau’s earlier imposition of a fine for improperly monopolizing use of a shared wireless communications channel, failing to monitor the channel to detect possible interference problems, and actually causing interference to co-channel licensees. The Bureau had warned the company repeatedly to change its behavior, but Mobile Relay did not do so.

Dish Network has its sights set on the 12 GHz band for 5G, and it isn’t backing down, even in the face of some pretty stiff competition. Dish—which is in the process of building out a cloud-native, open RAN-based 5G network—itself uses the 12 GHz band for direct broadcast satellite (DBS). Yet it says sharing with 5G in the band is feasible, and while it still wants to support the diminishing TV satellite business (DBS) business, it’s confident that sharing isn’t going to hurt those customers.

INCOMPAS and the Computer & Communications Industry Association (CCIA) filed joint public reply comments urging the Federal Communications Commission to follow the robust record supporting expanding the 12 GHz spectrum band for new or expanded terrestrial mobile use. As the data clearly shows, the FCC’s action to open up this key mid-band spectrum would accelerate mobile market competition, bolster the economy, and strengthen America’s 5G edge.

Verizon is rolling out an enhancement to 4G that absolutely blows away its own "nationwide" 5G, and that shows good signs for the new C-band 5G coming in 2022. Citizens Band Radio Service (CBRS), a set of airwaves close to the C-band, has quietly started rolling out nationwide. I got a tip on two locations near me, so I went to check it out. CBRS appeared on sites configured for all of Verizon's latest technologies: 4G, its "nationwide" Dynamic Spectrum Sharing (DSS) 5G, and its super-speedy ultra wideband (UWB) 5G.

We’ve been promised a fourth industrial revolution with fantastical things like remote surgery and driverless cars. Instead, what we have now is widespread 5G that’s more or less the same speed as (or even slower than) 4G and super-fast mmWave 5G in some parts of some major cities with highly limited range. So where is this 5G future we’ve been promised? The truth is that it’s coming along, but it will materialize more slowly and in less obvious ways than what we’ve been led to believe.

The next big spectrum tug of war will play out in the 12 GHz band, where a broad 500 MHz of spectrum could be available for fixed or mobile use, possibly involving 5G and Wi-Fi. The Federal Communications Commission in Jan adopted a notice of proposed rulemaking (NPRM) about possibly changing the rules for the 12 GHz band that could allow spectrum sharing and other changes. The NPRM is likely to generate a barrage of comments including diverse and, in some cases, mutually exclusive, recommendations.
